Engine Positions System Performance Bank 1
Code P0008 indicates that the Engine Control Module (ECM) has detected a correlation error between the crankshaft position sensor and the camshaft position sensor on Bank 1. This typically means the timing chain or belt has stretched or jumped a tooth, causing the camshaft and crankshaft to be out of sync. It can also be caused by a faulty variable valve timing (VVT) system, oil flow issues, or sensor problems.
01. Most Common Causes
- Stretched or jumped timing chain/belt
- Faulty camshaft or crankshaft position sensor
- Variable valve timing (VVT) solenoid or actuator failure
- Low engine oil pressure or dirty oil
- Worn timing chain tensioner or guides
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine misfire or rough idle
- Reduced engine power and performance
- Hard starting or no start
- Increased fuel consumption
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Inspect engine oil level and condition; check for proper oil pressure.
Step 3: Visually inspect timing chain/belt for slack or damage; check tensioner and guides.
Step 4: Test camshaft and crankshaft position sensors with a multimeter or oscilloscope.
Step 5: Perform a correlation test using a scan tool to compare cam/crank position data.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. Driving with P0008 can cause severe engine damage, including bent valves or catastrophic failure, especially if the timing chain jumps further.
How much does it cost to fix?▼
Repair costs typically range from $500 to $1500, depending on the cause. Timing chain replacement is labor-intensive and can cost $1000-$2000, while sensor replacement is cheaper ($150-$300).
