This summary uses the existing diagnostic information shown in full below.
This code means that the engine's computer thinks the parts inside the engine that help it run are not lined up correctly on one side of the engine.
The P0008 code indicates that the Engine Control Module (ECM) has detected a problem with the alignment of the engine's timing components, specifically in Bank 1.
The P0008 code is triggered when the ECM detects that the camshaft and crankshaft are not in the expected alignment. This misalignment can affect the engine's performance and efficiency. Bank 1 refers to the side of the engine containing cylinder 1.
• Check Engine Light is on
• Engine runs rough or misfires
• Reduced engine performance
• Stretched or worn timing chain
• Faulty timing chain tensioner
• Misaligned camshaft or crankshaft sprocket
ECM: Engine Control Module
Timing Chain: A metal chain connecting the crankshaft and camshaft, ensuring they turn in sync.
• Use an OBD-II scanner to confirm the code
• Inspect the timing chain and tensioner for wear
• Check the alignment of the camshaft and crankshaft
• Replace the timing chain if it is stretched
• Replace the timing chain tensioner
• Realign the camshaft and crankshaft sprockets
• OBD-II scanner
• Timing chain tool kit
• Wrench set
$500 to $1500
Difficult
• Chevrolet Traverse
• GMC Acadia
• Cadillac CTS
• Regular maintenance and oil changes
• Use high-quality engine oil
• Inspect timing components periodically
Engine Performance
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional
• Avoid driving the vehicle if performance is severely affected
Check with the vehicle manufacturer for potential coverage under powertrain warranty.
This code is commonly associated with vehicles that have timing chain issues, particularly in certain GM models.
High – This issue can lead to severe engine damage if not addressed promptly.
Driving with this code active can lead to engine failure, which is a safety risk.
• Engine at operating temperature
• Vehicle in park or neutral
The timing chain and related components are located inside the engine, usually at the front.
Q: Can I drive my car with a P0008 code?
A: It's not recommended as it can lead to severe engine damage.
Q: What happens if I ignore the P0008 code?
A: Ignoring the code can result in poor engine performance and potential engine failure.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
