P0016 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).

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.

The 2.4L DOHC non-turbo engine in the PT Cruiser is highly susceptible to oil sludge formation, particularly when oil changes are delayed beyond 3,000-5,000 miles or conventional oil is used. The engine design with its small oil passages and relatively high operating temperature creates ideal conditions for sludge. Sludge clogs oil passages, starving the valvetrain and camshaft bearings of lubrication, leading to ticking noises and eventual engine damage.
Common Symptoms
- Engine ticking or tapping noise, especially on cold start
- Oil pressure warning light flickering at idle
- Dark, thick sludge visible on oil filler cap or dipstick
- Excessive oil consumption between changes
- Check engine light with cam timing or oil pressure codes
How to Fix
Switch to full synthetic 5W-30 oil and change every 5,000 miles maximum. For engines with existing sludge, perform 3 consecutive oil changes at 1,000-mile intervals using synthetic oil to flush deposits. In severe cases where the engine is ticking, a manual cleaning may be needed — remove the valve cover and manually clean sludge from the cam journals and oil passages. If cam bearings are damaged from oil starvation, engine replacement may be needed ($2,000-$4,000).

Frequently asked questions
What does P0016 mean on a Chrysler?
P0016 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A." P0016 means the engine computer found that the crankshaft and camshaft position sensors on Bank 1 (Sensor A) are not lining up the way they should — the timing 'correlation' between them is out of range. These two sensors tell the computer where the pistons and valves are so it can time fuel injection and spark precisely. When their signals don't agree within tolerance, the computer sets this code. It generally indicates an engine timing issue, which may be a worn timing chain, a sticking variable valve timing component, or a sensor problem, and can cause rough running, hard starting, or potential engine damage if ignored. On Chrysler it is documented across 2 models: Sebring, PT Cruiser.
What are the most common causes of P0016?
The most common causes of P0016 are: Stretched timing chain or worn timing components (guides/tensioner), Faulty camshaft position sensor or crankshaft position sensor, Stuck or faulty variable valve timing (VVT/VCT) actuator or solenoid, Low or dirty engine oil affecting the VVT actuator, Clogged oil control valve or restricted oil passages, Timing chain/belt installed one tooth off after service, Damaged reluctor/tone ring on the crankshaft or camshaft, Wiring or connector faults at the position sensors. The specific cause varies by vehicle.
How much does it cost to fix P0016 on a Chrysler?
Published repair estimates on Chrysler range from $50 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.
