Code P1996 Description

The P1996 code indicates that there is friction too high in the intake camshaft adjustment for Bank 1. This means that there is an issue with the variable valve timing (VVT) system in the engine, specifically related to the intake camshaft on the first bank of cylinders. The VVT system is responsible for adjusting the timing of the opening and closing of the intake and exhaust valves to optimize engine performance and efficiency. When there is excessive friction in the intake camshaft adjustment mechanism, it can lead to timing issues, reduced engine performance, and potential long-term damage if not addressed promptly.
