P0008 on Pontiac
Engine Position System Performance - Bank 1
P0008 on Pontiac vehicles indicates engine position system performance - bank 1. Au7o has documented this code across 1 Pontiac model — most commonly on G6. 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 Pontiac range from $1,200 to $2,500, 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 Pontiac by Model
Pontiac G6(1 issue)
- G6 2.4L Ecotec (LE5/LAT) Timing Chain Stretch2007-2010
The 2.4L Ecotec LE5 in 2007-2010 G6 (and shared Cobalt SS, Malibu, HHR, Saturn Aura/Ion, Solstice) develops timing chain stretch — a very well-documented engineering issue across Ecotec forums and independent shops. Root cause: GM's original Oil Life Monitor allowed intervals up to 12,000 miles, starving the chain. Note: while GM issued Special Coverage Adjustment 11340C covering timing chain stretch on the 3.6L LFX/LLT V6, the 2.4L Ecotec did NOT receive the same blanket warranty extension. Some owners obtained goodwill repairs through dealer-level escalation.

What does P0008 mean on Pontiac?▼
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.
