Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P2610: General Description
The powertrain control module (PCM) has a built-in ignition off timer that measures the duration from ignition off to the next ignition on. The measured duration is used for evaporative emission (EVAP) leak check and temperature assumption of the catalytic converter. The CPU in the PCM accesses the ignition off timer when reading the measured duration. If the access process to the ignition off timer fails, or an abnormality is found in the read data, the PCM detects a malfunction and stores a DTC.
