P0008 on Ford
Engine Position System Performance - Bank 1
P0008 on Ford vehicles indicates engine position system performance - bank 1. Au7o has documented this code across 1 Ford model — most commonly on F-150. 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 Ford range from $800 to $3,600, 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 Ford by Model
Ford F-150(1 issue)
- 3.5L EcoBoost cam phaser rattle on cold start2017-2020
Second-gen 3.5L EcoBoost engines develop a loud rattle/knock from the front timing cover for 2-5 seconds on cold start (and sometimes at idle). The variable-cam-timing (VCT) phasers have a lock pin that fails to engage on startup, allowing the phaser to rattle against the cam sprocket. Over time the phasers and timing chain wear, which can throw cam/crank correlation codes and, if ignored, lead to further timing component damage. Ford acknowledged it in service bulletins and a Customer Satisfaction Program with an extended warranty.

What does P0008 mean on Ford?▼
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.
