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 3 Cadillac models — most commonly on SRX, STS, XTS. 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.
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 SRX(1 issue)
- High-Feature V6 Timing-Chain DTCs Require Exact Kit Identification2010-2012
GM bulletin 12-06-01-009E covers listed 2010-2012 SRX High Feature V6 applications when worn timing chains set P0008, P0009 or P0016-P0019. It identifies application-specific service kits and warns that sprockets, actuators and guides should not be replaced automatically; guides are replaced only when wear reaches the base friction material.
Cadillac STS(1 issue)
- 3.6L V6 Timing-Chain DTCs Require Exact Kit and Guide Inspection2007-2011
GM bulletin 12-06-01-009E covers listed 2007-2011 STS 3.6L High Feature V6 applications when worn timing chains set P0008, P0009 or P0016-P0019. It identifies application-specific service kits and warns that sprockets, actuators and guides should not be replaced automatically; guides are replaced only when wear reaches the base friction material.
Cadillac XTS(1 issue)
- Multiple Cam/Crank Correlation DTCs Require Chain, Tensioner and Reluctor Diagnosis2013-2019
GM PIP3423P covers 2013-2019 XTS vehicles with the 3.6L LFX or LF3 engine when two or more of P0008, P0009 and P0016-P0019 are present. GM directs technicians to check for loose chains or tensioners and, if normal SI diagnosis does not find the cause, inspect whether the crankshaft-sensor reluctor moved. The bulletin does not establish automatic chain replacement.

What does P0008 mean on Cadillac?▼
P0008 stands for "Engine Position System Performance - Bank 1." 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. On Cadillac specifically, this code is documented across 3 models.
What causes P0008 on Cadillac vehicles?▼
Common causes on Cadillac: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0008 on a Cadillac?▼
Repair costs vary widely depending on the root cause and specific Cadillac model.
Which Cadillac models have P0008 documented?▼
Au7o has documented P0008 on 3 Cadillac models: SRX, STS, XTS.
