Review the 'Possible Causes' mentioned above and visually examine the corresponding wiring harness and connectors. Ensure to check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.
To diagnose the P242F code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
The Powertrain Control Module (PCM) monitors the pressure decrease at the diesel particulate filter following a diesel particulate filter regeneration for a concern. The PCM calculates the amount of ash and the pressure increase the ash generates in the diesel particulate filter. During a regeneration the PCM expects the pressure to decrease. The amount of pressure decrease expected by the PCM is based on the temperature and flow of the exhaust gas. The test fails when the pressure reading at the diesel particulate filter pressure sensor does not decrease by the amount determined by the PCM.
