P0008 on Suzuki: How to Diagnose & Fix

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 Suzuki it is documented across 1 model: Swift.

The most common causes of P0008 are: 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. The specific cause varies by vehicle.

Published repair estimates on Suzuki range from $400 to $900 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
