05047787AC and 5047787AC are alternate catalog formats for the same Mopar intake oil control valve used on selected Chrysler, Dodge, Jeep, and Ram 3.6L engines. To confirm the correct replacement, I check the exact part number, vehicle year, make, model, trim, engine, VIN, connector, and intake-side application before ordering.

The 05047787AC oil control valve is an intake-side engine variable valve timing oil control valve, also called a VVT solenoid, camshaft oil control solenoid, or spool valve. It regulates pressurized engine oil sent to the intake camshaft phaser, allowing the engine control module to adjust intake cam timing according to engine speed, load, temperature, and operating conditions. The component is associated with the Chrysler Pentastar 3.6L V6 family, but the part number alone does not prove that it fits every 3.6L vehicle.
In catalogs, the number may appear as 05047787AC, 5047787AC, or with spaces and punctuation removed. These formats generally refer to the same Mopar intake oil control valve, while the leading zero may be omitted in some electronic parts systems. I still verify the catalog record and VIN because similar-looking intake, exhaust, VVT, and variable valve lift components can have different electrical and mechanical applications.
The component is not the camshaft phaser itself. The valve controls oil flow to the phaser, while the phaser changes camshaft position. A diagnostic code related to cam timing may involve the oil control valve, wiring, oil passages, oil pressure, the camshaft position sensor, the phaser, or mechanical timing, so replacing the valve without testing can lead to an unnecessary repair.
The terms 05047787AC oil control solenoid, oil control valve, VVT solenoid, and intake camshaft oil control valve are often used for the same general component. Mopar catalog descriptions commonly identify 5047787AC as an “oil control valve” with an “intake” application, while other parts catalogs describe it as an engine variable valve timing solenoid. These labels describe the operating role rather than separate parts automatically.
In most repair and parts-ordering contexts, an oil control valve and a VVT solenoid refer to the same type of electronically controlled oil valve. The engine computer energizes the solenoid, and the internal valve directs oil toward the appropriate camshaft phaser circuit. The important distinction is not usually the name but the application: intake versus exhaust, engine family, connector design, mounting arrangement, and calibration.
I do not use a visual match as the final identification method. Two valves may share a similar body shape while having different oil ports, electrical resistance, connector indexing, or flow characteristics. A catalog description that specifically states “intake” is more useful than a photograph alone, but VIN confirmation remains the safest purchasing step.
The numbers 05047787AC and 5047787AC refer to the same Mopar part-number family in the catalogs reviewed for this guide. The difference is the leading zero, which some systems retain and others suppress when displaying a manufacturer part number. If a seller lists 5047787AC instead of 05047787AC, I compare the manufacturer reference, application description, and supersession information before treating it as a valid substitute.
| Catalog detail | What it usually means | What I verify before ordering |
|---|---|---|
| 05047787AC | Full Mopar-style reference with leading zero | Exact catalog match and vehicle application |
| 5047787AC | Same reference with leading zero omitted | Manufacturer number, intake designation, and VIN fitment |
| Intake oil control valve | Valve for intake camshaft timing control | Engine diagram and position |
| VVT solenoid or spool valve | Alternate functional description | Connector, mounting, and engine configuration |
A listing that only says “fits 3.6L” is incomplete. Chrysler, Dodge, Jeep, and Ram vehicles can use different revisions, wiring layouts, emissions configurations, and camshaft control arrangements even when displacement is identical. I treat 5047787AC as the same number only when the seller’s catalog identifies it as the Mopar intake oil control valve and confirms the specific vehicle.
I begin by removing dirt and oil residue from the visible valve body without damaging the connector or seal. I record every stamped, molded, printed, or laser-marked identifier, including 05047787AC, 5047787AC, supplier codes, date markings, and directional labels. A partial number can be useful, but I do not place an order until the complete part number is matched against a reliable catalog.
The original valve may not carry the complete service part number in an easily visible location. In that case, I photograph the connector, mounting flange, oil passages, O-ring position, and installation location. These details help distinguish the intake valve from a visually similar exhaust valve or another VVT component.
Next, I collect the vehicle year, brand, model, trim, engine size, fuel type, drivetrain if requested by the catalog, and transmission information. The relevant application group includes selected Chrysler Pacifica and Voyager models, Dodge Durango models, Jeep Gladiator, Grand Cherokee, Grand Cherokee L, and Wrangler models, plus Ram 1500 and ProMaster vehicles equipped with applicable 3.6L engines. These model groups cover multiple production years and configurations, so the model name alone is not enough.
For example, a 2019 Ram 1500 3.6L and a 2022 Ram ProMaster 1500 3.6L may both appear in a broad 3.6L search but still require separate catalog confirmation. The same principle applies to hybrid, mild-hybrid, flex-fuel, and standard gasoline configurations. I use the engine code or factory build information when the parts catalog requests it.
VIN-based parts verification is the strongest practical check because it connects the vehicle to its factory build record. I provide the complete 17-character VIN to a Mopar dealer, qualified parts supplier, or catalog system that supports VIN lookup. I ask the seller to confirm that the result specifies intake oil control valve 05047787AC or 5047787AC, rather than a generic VVT solenoid.
I also compare the VIN result with the vehicle’s year, make, model, trim, engine, and production details. If the VIN lookup returns a different superseding number, I ask whether 05047787AC has been replaced by that number and whether the replacement is a direct service substitute. I keep the written fitment response with the order record in case the part needs to be returned.
The 3.6L V6 can use separate oil control valves for intake and exhaust camshaft control. Catalog diagrams, engine illustrations, repair manuals, and application notes can show whether 05047787AC belongs on the intake side. In the catalog records reviewed for this part number, 5047787AC is described as the intake valve, while a separate part may be listed for the exhaust position.
I compare three pieces of information: the catalog position, the engine diagram, and the physical location of the removed component. I do not assume that left-bank, right-bank, front, rear, intake, and exhaust descriptions are interchangeable. If the vehicle uses multiple valves with similar housings, the position designation must match before purchase.
The 05047787AC oil control valve is associated with selected Chrysler, Dodge, Jeep, and Ram vehicles using the 3.6L V6. Catalog examples include Chrysler Pacifica from approximately 2017–2024 and Voyager from approximately 2020–2024; Dodge Durango from approximately 2016–2025; Jeep Gladiator from approximately 2020–2025, Grand Cherokee from approximately 2016–2024, Grand Cherokee L from approximately 2021–2024, and Wrangler from approximately 2018–2025; and Ram 1500 from approximately 2019–2024 and ProMaster applications from approximately 2022–2024.
These year ranges are reference examples, not a substitute for VIN verification. Trim, engine version, fuel system, hybrid equipment, emissions package, and production changes can affect fitment. I use the vehicle-specific catalog result as the final authority rather than assuming that every 3.6L application uses the same intake valve.
The cataloged part is a new genuine Mopar intake oil control valve, with 5047787AC commonly shown as the manufacturer part number. One Mopar parts listing shows an MSRP of approximately $145, while dealer-discounted listings may be near $98 before shipping and tax. Aftermarket replacements may cost less, but the lower price should be evaluated against connector accuracy, O-ring quality, seller warranty, return terms, and documented vehicle coverage.
| Purchase option | Typical price position | Advantages | Checks required |
|---|---|---|---|
| Genuine Mopar | About $98–$145 in listed examples | Factory part number and application reference | Confirm VIN, intake position, and warranty terms |
| Aftermarket replacement | Varies by brand and seller | Potentially lower purchase cost | Check supplier testing, connector, seal, and coverage |
| Supplier-direct replacement | Varies by specification and quantity | May suit repair shops or wholesale buyers | Request fitment data, inspection records, and return policy |
Ostberg is a supplier of engine VVT oil control valves and transmission-related components, and its product catalog lists a Chrysler 3.6L oil control valve under the 05047787AC and 5047787AC references. If I consider an Ostberg or other aftermarket replacement, I request the exact application list, intake-side designation, connector photos, dimensional information, and warranty conditions. A supplier listing is useful for comparison, but I still match the replacement against the original part and VIN.
Warranty length and coverage depend on the seller and product category. A genuine Mopar part may carry a factory-backed warranty under the seller’s terms, while aftermarket coverage can exclude labor, diagnostic costs, or damage caused by incorrect installation. I confirm whether the warranty requires professional installation, proof of purchase, or return of the failed valve.
A faulty or restricted oil control valve may contribute to variable valve timing codes, rough idle, difficult starting, reduced acceleration, increased fuel consumption, or an illuminated check-engine light. The engine may also show delayed camshaft response or inconsistent operation when oil temperature changes. These symptoms can overlap with problems involving low oil level, incorrect oil viscosity, sludge, wiring, a camshaft sensor, a phaser, timing components, or engine control software.
For that reason, symptoms do not prove that the valve itself has failed. I check engine oil level and condition, inspect the connector for corrosion or loose terminals, scan for diagnostic codes, and follow the manufacturer’s test procedure before replacing the part. If the oil contains debris or the engine has restricted oil passages, a new valve may not correct the underlying problem.
Before installing 05047787AC, I compare the new valve with the old part on several points. The connector shape and terminal position must match, the mounting flange must align, the oil passage arrangement must correspond, and the O-ring must be present and undamaged. I do not reuse a cut, flattened, hardened, or oil-soaked seal when the service procedure calls for replacement.
I clean the mounting area so dirt does not enter the engine oil passage. I apply only the lubricant specified by the repair procedure to the O-ring, install the valve without twisting the seal, and use the manufacturer’s torque specification for the retaining fastener. I avoid guessing the torque because a loose fastener can cause leakage, while excessive torque can damage the housing or engine threads.
After installation, I reconnect the harness fully and check that the wiring is routed away from hot or moving components. I verify the oil level, clear diagnostic codes only after recording them, and start the engine while checking for leaks or abnormal noise. A final scan, road test, and repeat inspection help confirm that the camshaft timing system responds normally and that no new codes appear.
To identify the correct component, I first confirm that the listing describes the Mopar intake oil control valve and that 05047787AC and 5047787AC are being used as alternate formats for the same part number. I then match the valve to the vehicle year, make, model, trim, 3.6L engine configuration, intake-side position, connector, and engine diagram. Finally, I verify the application through the VIN before comparing OEM and aftermarket pricing.
The safest purchase is not automatically the cheapest or the most expensive option. I select the part with confirmed VIN fitment, a matching intake designation, correct connector and O-ring design, clear warranty terms, and a return policy that covers incorrect catalog information. When symptoms are present, I also diagnose the oil system, wiring, sensors, and camshaft phaser so that replacing 05047787AC addresses the actual fault rather than only the warning code.
