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: Powertrain Control Module (PCM) Internal Power Off Timer Malfunction: General Description
The powertrain control module (PCM) has a built-in power off timer that measures the duration of time the ignition switch is off. This measurement is used for evaporative emission (EVAP) leak detection and temperature assumption of the catalytic converter.
The CPU in the PCM accesses the power off timer when reading the measured time. When the access process fails, a malfunction is detected and a DTC is stored. When an abnormality is found in the read data, a malfunction is detected and a DTC is stored.
