Will timing cause code p0172 and p0175?

Answer 1

Codes P0172 and P0175 indicate that the engine is running rich on bank 1 and bank 2, respectively. While timing issues can affect engine performance and fuel mixture, these specific codes are more commonly related to problems with fuel delivery, air intake, or sensor malfunctions (like the MAF or O2 sensors). Therefore, while incorrect timing can contribute to overall engine problems, it is not a direct cause of these rich condition codes. Proper diagnostics should focus on fuel and air management components.
