P0012 on Chrysler by model: symptoms, diagnosis and fix
The 2.7L V6 engine is highly susceptible to oil sludge buildup due to higher than average operating temperatures, insufficient oil capacity (5 quarts instead of 6), and a timing chain-driven water pump that can leak coolant into the crankcase. Engine failures have been reported as early as 20,000 miles, but most commonly occur between 50,000 and 60,000 miles. Multiple class action lawsuits were filed.
Common Symptoms
- Engine rattling noise at startup
- Check engine light
- Oil pressure warning light
- Engine overheating
- Rough idle or misfires
- Loss of power
- Engine knocking sounds
How to Fix
Prevention requires strict oil change intervals of 3,000 miles or less with high-quality synthetic oil. Once sludge has formed, engine flush treatments may help in early stages. Severe cases require timing chain replacement ($1,289-$1,642) or complete engine replacement ($3,500-$6,000).
Sources for this issue (1)
The 2.7L V6 uses a timing chain that stretches prematurely due to oil sludge buildup restricting lubrication. The chain-driven internal water pump can seize and cause the timing chain to jump, destroying the engine. Water pump, timing chain, guides, and tensioner are all internal components requiring extensive disassembly to access. 7-8 hours labor.
Common Symptoms
- Rattling noise from engine on startup
- Check engine light with timing codes
- Engine performance deterioration
- Engine misfires
- Complete engine failure if chain jumps
How to Fix
Replace timing chain kit (Mopar 68036787AA, updated design), water pump (Mopar 4892425AA - MUST use Mopar updated design, NOT aftermarket), all guides, tensioner, and seals as a complete job. Preventive maintenance at 100,000 miles. Always replace water pump with timing chain.

Frequently asked questions
What does P0012 mean on a Chrysler?
P0012 stands for "Intake Camshaft Position Timing - Over-Retarded (Bank 1)." This code means the intake camshaft timing on Bank 1 is more retarded than the computer commanded — the variable valve timing system isn't reaching its target position. The computer controls camshaft timing through an oil-fed actuator (cam phaser) and a control solenoid; when actual timing lags the desired setting, this code sets. It is commonly caused by oil flow problems (low, dirty, or wrong oil), a stuck solenoid, or a worn cam phaser. Symptoms can include rough idle, reduced power, poor fuel economy, and sometimes rattling on startup. On Chrysler it is documented across 1 model: Sebring.
What are the most common causes of P0012?
The most common causes of P0012 are: Low, dirty, or incorrect-viscosity engine oil, Faulty or stuck intake camshaft (VVT) oil control solenoid, Worn or stuck camshaft phaser/actuator, Clogged solenoid screen or oil passages, Wiring or connector problems at the solenoid, Timing chain wear or stretch affecting cam timing, Faulty camshaft position sensor. The specific cause varies by vehicle.
How much does it cost to fix P0012 on a Chrysler?
Published repair estimates on Chrysler range from $1,200 to $6,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
