Yes, a P0495 error code, which indicates a problem with the secondary air injection system, can contribute to a P0128 error code, which signals that the engine is not reaching the proper operating temperature. If the secondary air system is malfunctioning, it can affect engine performance and efficiency, potentially leading to insufficient heat generation. This could result in the engine taking longer to warm up, triggering the P0128 code. It's advisable to address both codes to ensure optimal engine function.
