The 05047787AC Oil Control Valve Replacement Guide for Chrysler 3.6L V6 Engine explains how I identify, diagnose, replace, and test the intake-side variable valve timing oil control valve. The part is used on selected Chrysler, Dodge, Jeep, and Ram vehicles with the 3.6L Pentastar V6, but exact application depends on model year, engine configuration, connector design, and VIN. Before ordering a replacement, I verify the original part number and investigate the diagnostic code rather than replacing the valve based on symptoms alone.
The 5047787AC valve regulates engine oil flow to the intake camshaft phaser. When the valve sticks, becomes contaminated, loses electrical control, or receives insufficient oil pressure, the engine may set P0011, run roughly, hesitate, stall, or lose fuel economy. A correct repair therefore includes oil and wiring checks, physical comparison of the replacement, careful installation, and a post-repair scan.
The 05047787AC oil control valve is an electrically controlled hydraulic valve in the Chrysler 3.6L V6 variable valve timing system. It is commonly identified as an intake-side VVT solenoid or camshaft position actuator solenoid, although the exact naming varies between manufacturers and parts catalogs. Its job is to meter pressurized engine oil to the intake camshaft phaser so the powertrain control module can adjust valve timing.
The valve normally has an electrical connector, a solenoid coil, a valve spool, sealing surfaces, and an insertion body that fits into the cylinder-head oil passage. The control module changes the solenoid’s electrical duty cycle, which moves the internal spool and alters oil flow. Because the valve depends on clean oil and correct electrical signals, a fault can originate in the valve, the oil supply, the harness, the connector, the cam phaser, or the timing system.
The part number alone does not prove universal compatibility. I check the vehicle identification number, model year, engine code, original connector, valve shape, mounting arrangement, and catalog application before installation. This is especially important when comparing Jeep Wrangler JK and JL models, because the two generations can use different engine-management components even when both have a 3.6L V6.

The 5047787AC oil control valve is one part of a larger system that includes the powertrain control module, camshaft and crankshaft position sensors, oil passages, cam phasers, timing chains, and engine lubrication system. The valve does not independently set camshaft timing. Instead, it responds to electronic commands and controls hydraulic oil flow that moves the phaser.
This explains why replacing the VVT solenoid may not correct every P0011 or P0017 condition. If the engine has low oil pressure, sludge in the passage, a damaged connector, stretched timing components, or a worn cam phaser, a new valve may produce the same fault. I treat the solenoid as one possible cause rather than assuming that the stored code identifies the failed component.
The intake-versus-exhaust distinction also matters. The 5047787AC application described in this guide is the intake-side valve for compatible applications, while an exhaust-side valve may have a different OE number, body shape, connector position, or electrical specification. I compare the printed number, electrical connector, mounting location, and engine position before removing the original part.
Common symptoms of a failing 5047787AC oil control valve include a check-engine light, rough idle, hesitation during acceleration, reduced fuel economy, hard starting, intermittent stalling, and reduced engine performance. Some vehicles may have only a stored code with no obvious drivability complaint. The symptom pattern depends on whether the valve is stuck open, stuck closed, electrically open, contaminated, or receiving inadequate oil flow.
P0011 generally indicates that the intake camshaft timing is more advanced than the control module expects, or that the commanded and measured cam positions do not agree. On a Jeep or other Chrysler vehicle, P0011 may result from a sticking oil control valve, incorrect oil level, degraded oil, restricted oil passages, damaged wiring, a faulty camshaft sensor, a failing phaser, or a mechanical timing problem. I confirm the cause with testing instead of treating P0011 as proof that the solenoid itself is defective.
Before replacement, I perform the following checks:
Confirm the engine oil level and condition using the manufacturer’s specified viscosity and service interval.
Inspect the valve connector for broken locks, oil intrusion, corrosion, pushed-back terminals, or loose wiring.
Check whether P0011 appears alone or with related camshaft, crankshaft, oil-pressure, or misfire codes.
Compare commanded and actual camshaft angles with a scan tool when live data is available.
Inspect the old valve for sludge, damaged seals, a bent body, or a spool that does not move correctly.
Consider oil-pressure testing and mechanical timing inspection if the fault remains after electrical and hydraulic checks.
A bad oil control valve can cause rough idle or stalling, but those symptoms are not exclusive to the valve. Vacuum leaks, ignition faults, low fuel pressure, throttle-body problems, and camshaft timing defects can create similar behavior. If the engine stalls in traffic, loses oil pressure, or produces loud timing-chain noise, I stop driving it until the underlying risk is assessed.
The replacement itself is often a moderate repair for an experienced technician, but access varies by vehicle. A typical job requires basic hand tools, a small pick or trim tool, a flashlight, a clean container, shop towels, electrical contact cleaner, a scan tool, and the correct replacement seal if one is not supplied. I also keep the vehicle service information available for the exact fastener torque, access procedure, and oil specification.
I park on a level surface, apply the parking brake, switch off the ignition, and allow the engine to cool. I disconnect the negative battery cable when the service procedure or vehicle design requires it, especially if the connector is close to exposed electrical contacts. I then photograph the original valve and connector before disassembly.
Next, I compare the replacement with the original part. The connector orientation, terminal count, mounting flange, seal location, insertion depth, body diameter, and part number should match. A replacement marked as 05047787AC should be treated cautiously because the extra leading zero may be a catalog formatting variation, a seller error, or a different part reference; I verify it against the vehicle VIN and the original 5047787AC number before installation.
The exact location depends on the vehicle and engine layout, but the intake-side valve is mounted in the cylinder-head or camshaft-control area associated with the intake camshaft. I do not identify it by position alone because engine packaging differs between Wrangler, Grand Cherokee, Durango, Pacifica, Ram, and other applications.
The JK-versus-JL distinction is critical. A Jeep Wrangler JK with a 3.6L engine and a Wrangler JL with a 3.6L engine may not share the same valve, connector, harness routing, calibration, or service procedure. I confirm the generation, production year, engine code, and VIN before purchasing a 5047787AC replacement for either platform.
After cleaning loose dirt from the surrounding area, I release the connector lock without pulling on the wires. If the connector is stuck, I use a small tool on the locking tab rather than prying against the terminals. I remove the retaining fastener, if fitted, and pull the valve straight out with controlled movement.
Some valves may resist removal because of oil residue or a hardened seal. I avoid twisting the valve aggressively or striking the housing, because damage to the cylinder-head bore can create an oil leak or prevent the replacement from sealing. I place a clean cloth below the opening to catch oil and immediately cover the passage if the repair is interrupted.
I compare the old valve with the new one and inspect the removed part for sludge, varnish, metal debris, damaged O-rings, or signs of overheating. If the valve is heavily contaminated, I examine the engine oil and filter for evidence that the contamination is not limited to the solenoid. A dirty valve may be a symptom of poor oil maintenance or an internal engine problem.
I clean the connector with electrical contact cleaner and allow it to dry. I do not pack the connector with grease unless the vehicle service information specifically permits it, and I never force debris into the oil passage. If I find significant metal particles, low oil pressure, or damaged wiring, I correct those problems before treating the valve replacement as complete.
I lubricate the new seal with a small amount of clean engine oil when permitted by the service procedure. I align the valve with the bore and press it in evenly, avoiding side loading that could cut the seal. I reinstall the fastener and tighten it to the vehicle-specific factory torque rather than using a general torque estimate.
I reconnect the electrical plug until the lock engages and confirm that the harness is routed away from the exhaust, moving linkage, and sharp edges. I reinstall covers or intake components in their original positions. Before starting the engine, I check that no tools, rags, or loose fasteners remain near the belt, fan, or throttle area.
After reconnecting the battery if it was removed, I start the engine and allow it to reach operating temperature while checking for oil leaks and abnormal timing noise. I clear the stored code only after recording freeze-frame data, because that information can help if the fault returns. I then monitor idle quality, camshaft angle data, and system voltage when the scan tool supports those functions.
A proper road test includes cold-start behavior if possible, normal acceleration, steady cruising, and several idle periods. I rescan the vehicle after the test and confirm whether P0011 or related codes have returned. If the code reappears, I stop replacing parts and continue with wiring, oil-pressure, camshaft-sensor, phaser, and mechanical timing tests.
When I compare an OEM 5047787AC replacement with an aftermarket valve, I focus on application accuracy, connector fit, sealing dimensions, coil resistance, warranty terms, return policy, and supplier documentation. A lower purchase price does not compensate for a wrong connector, incorrect oil-flow calibration, poor seal fit, or a part that causes repeat diagnostic work. The most useful comparison is the total repair cost, including labor and the risk of removing the part again.

Ostberg manufactures engine oil control valves, timing components, and transmission parts through Tianjin Ostberg Science & Technology Co., Ltd. Its published company information describes a 3,600-square-meter factory, more than 45 employees, over 30 production machines, and annual capacity of approximately 1.4 million pieces. The company also reports ISO/IATF 16949-related manufacturing certification and inspection equipment, but I still verify the exact 5047787AC application, test documentation, warranty, and packaging label before ordering.
I use the following checklist before installing a 5047787AC replacement:
Confirm the brand, model, production year, engine displacement, and engine code.
Verify whether the vehicle is a Wrangler JK or Wrangler JL.
Check Pacifica, Grand Cherokee, Durango, and Ram applications individually rather than assuming shared fitment.
Compare the original intake-side valve with the replacement body and connector.
Confirm the OE number through a VIN-based parts catalog.
Check whether the vehicle uses a separate exhaust-side valve with a different part number.
Confirm the replacement includes the correct seal, retaining hardware, and electrical configuration.
Review the seller’s return terms before opening or installing the part.
If the oil is low, overdue, contaminated, or the wrong viscosity, I correct the oil condition and retest before replacing the valve. If the connector has corrosion or an open circuit, I repair the wiring and verify continuity under movement. If the valve fails electrical or mechanical inspection and the oil system is clean, replacing the 5047787AC solenoid is reasonable.
If the new valve does not correct P0011, I evaluate oil pressure, camshaft sensor signals, camshaft position data, phaser operation, timing-chain condition, and mechanical alignment. A cam-phaser repair may be required when the phaser cannot hold commanded position or produces abnormal mechanical noise. This decision tree prevents unnecessary parts replacement and reduces the chance of masking a timing-system failure.
The 5047787AC Oil Control Valve Replacement Guide for Chrysler 3.6L V6 Engine comes down to three priorities: verify fitment, diagnose the cause, and validate the repair. I identify 5047787AC as the intake-side oil control valve for compatible Chrysler, Dodge, Jeep, and Ram 3.6L V6 applications, then confirm the VIN, engine position, connector, and JK-versus-JL generation before ordering.
For a P0011 condition, I inspect oil level, oil condition, wiring, connector integrity, live camshaft data, and related codes before replacing the solenoid. During installation, I protect the oil passage, replace or lubricate the seal correctly, use the vehicle-specific torque specification, and keep the intake and exhaust valve positions separate. Afterward, I clear codes, check for leaks, complete a road test, and rescan the vehicle. If P0011 returns, the next inspection should include oil pressure, sensors, cam phasers, and mechanical timing rather than another unverified valve.
