P0008 on Cadillac
Engine Position System Performance - Bank 1
P0008 on Cadillac vehicles indicates engine position system performance - bank 1. Au7o has documented this code across 1 Cadillac model — most commonly on STS. P0008 means the engine computer detected that Bank 1 of the engine is timed incorrectly relative to where it should be — specifically, the relationship between the crankshaft and camshaft positions on that bank is off. The 'Engine Position System' refers to the components (timing chain/belt, sprockets, tensioners, and the variable valve timing actuators) that keep the camshafts synchronized with the crankshaft. When the computer commands a timing position but the sensors report the bank is out of the expected range, it sets this code. It generally signals a mechanical timing problem on Bank 1 that can affect performance and, if severe, risk internal engine damage. Typical repair costs on Cadillac range from $1,500 to $3,000, depending on the specific model and root cause.
Common Causes of P0008
- •Stretched or worn timing chain
- •Failed or worn timing chain guides or tensioner
- •Faulty camshaft position (VVT/VCT) actuator or solenoid
- •Low or dirty engine oil affecting timing actuator operation
- •Jumped or mistimed timing chain/belt after service
- •Faulty crankshaft or camshaft position sensor
- •Clogged oil control valve or oil passages
P0008 on Cadillac by Model
Cadillac STS(1 issue)
- 3.6L V6 Timing Chain Stretch and Guide Failure2005-2011
The 3.6L V6 LY7 engine suffers from premature timing chain stretch and plastic timing chain guide failure, often before 100,000 miles. The stretched chain causes valve timing errors that trigger check engine lights and can eventually lead to jumped timing and catastrophic engine damage. This is one of the most expensive repairs on the STS.
