Ready to get started? Let’s jump right in.
Key Takeaways
- P0008 indicates an issue with the engine’s timing system, specifically the alignment of the crankshaft and camshaft.
- Common symptoms include the Check Engine Light, poor performance, rough idling, and decreased fuel efficiency.
- Causes range from a stretched timing chain to faulty sensors or wiring issues.
- Diagnosing involves checking the timing chain, tensioner, sensors, and wiring.
- Repairs may require replacing worn parts, correcting timing alignment, or updating ECM software.
- Use an OBD-II scanner to confirm and clear the code after repairs.

What Does P0008 Trouble Code Mean?
The P0008 trouble code means there is a problem with the engine’s timing system.
Specifically, it signals that the Engine Control Module (ECM) has detected an issue with the alignment between the crankshaft and camshaft on Bank 1 of the engine.
These components must be in sync for the engine to run efficiently.
When the ECM picks up that these parts are out of alignment, it triggers the P0008 code.
This misalignment can cause various issues, such as poor engine performance, increased fuel consumption, and potential engine damage if left unaddressed.
In most vehicles, this code is common in engines with Variable Valve Timing (VVT) systems. The VVT system adjusts the timing of the camshaft to improve engine performance and efficiency.
When something goes wrong in this system, it affects the timing, causing the ECM to register the P0008 code.
Several factors can lead to the P0008 code, such as a stretched timing chain, worn timing chain tensioner, or a faulty camshaft or crankshaft position sensor.
In some cases, the issue might be related to the ECM itself or wiring problems.
If you encounter the P0008 code, it’s essential to address it promptly. Ignoring it can lead to more severe engine problems, higher repair costs, and potentially leaving you stranded.
Diagnosing and fixing the issue typically involves inspecting the timing chain and related components, replacing any worn or damaged parts, and ensuring proper alignment.
Understanding the P0008 code helps you know what to expect when you take your car to a mechanic or decide to tackle the problem yourself.
P0008 Trouble Code Symptoms
When the P0008 code appears, your car will likely exhibit several noticeable symptoms:
- Check Engine Light is on
- Poor engine performance
- Rough idling or stalling
- Decreased fuel efficiency
- Engine misfires
- Unusual engine noises
P0008 Trouble Code Causes
The P0008 code can be triggered by several underlying issues:
- Stretched or worn timing chain
- Faulty timing chain tensioner
- Worn timing chain guides
- Defective camshaft or crankshaft position sensor
- Incorrect timing chain installation
- ECM malfunction or software issues
- Wiring problems in the timing system
How To Fix A P0008 Trouble Code
Fixing a P0008 trouble code involves diagnosing the root cause and performing the necessary repairs. Here’s how you can tackle this issue:
1. Check the Code
Use an OBD-II scanner to confirm the P0008 code and check for any additional related codes.
2. Inspect the Timing Chain
The most common cause is a stretched or worn timing chain. Remove the timing cover and inspect the chain for any signs of wear or stretching. Replace if necessary.
3. Examine the Tensioner and Guides
Check the timing chain tensioner and guides. If they are worn or damaged, they can cause the chain to lose tension and misalign. Replace these components if needed.
4. Test the Sensors
Use a multimeter to test the camshaft and crankshaft position sensors. Ensure they are functioning correctly and providing accurate readings. Replace any faulty sensors.
5. Check the Wiring
Inspect the wiring and connections to the camshaft and crankshaft position sensors. Look for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring.
6. Verify Timing Alignment
Ensure that the timing chain is properly aligned. Incorrect installation can cause the P0008 code. Refer to your vehicle’s service manual for the correct timing marks and procedures.
7. Update ECM Software
In some cases, a software update for the Engine Control Module (ECM) may be necessary. Check with your vehicle manufacturer for any available updates.
8. Clear the Code
After performing the necessary repairs, use the OBD-II scanner to clear the code. Start the engine and monitor for any reappearance of the P0008 code.
By following these steps, you can diagnose and fix the P0008 trouble code, ensuring your engine runs smoothly and efficiently. If you’re unsure about any step, it’s always a good idea to consult a professional mechanic.
