P0016 on Mitsubishi: How to Diagnose & Fix
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A
1 Mitsubishi model · 1 documented issue · 1 critical · $800-$2,000 repair
P0016 on Mitsubishi by model: symptoms, diagnosis and fix
The 4B11 engine timing chain stretches over time, particularly when oil changes are neglected. Chain stretch leads to retarded cam timing, rough idle, and potential engine damage if the chain jumps a tooth on the sprockets.
Common Symptoms
- Rattling noise on cold start
- Check engine light for cam timing
- Rough idle
- Reduced power and fuel economy
How to Fix
Replace the timing chain, tensioner, and guides as a set. Use the updated Mitsubishi timing chain kit with the improved tensioner. Maintain strict 5,000-mile oil change intervals to minimize chain wear.

Frequently asked questions
What does P0016 mean on a Mitsubishi?
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 Mitsubishi it is documented across 1 model: Lancer.
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 Mitsubishi?
Published repair estimates on Mitsubishi range from $800 to $2,000 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.
