Suzuki XL-7 check engine code P0008 related to timing chain replacement issue and concerns about manufacturing defects on Suzuki XL-7

Some Suzuki XL-7 owners report experiencing issues related to check engine code P0008, which signifies problems with engine timing and performance on Bank 1. Common symptoms include noticeable noises from the timing chain area and an illuminated check engine light. Possible causes of the P0008 code include faulty camshaft phasers, timing chain issues, low engine oil pressure, sensor malfunctions, or other component failures. Repairing this code can be challenging, as it typically requires opening the engine to inspect and replace components like the timing chain, tensioner, idler sprocket, or CMP actuator. Additionally, some owners express concerns about manufacturing defects that may lead to failures, such as a timing chain tensioner not receiving adequate oil. The diagnostic process involves the ECM detecting misalignment between the bank 1 camshaft and crankshaft, further complicating resolution efforts.
