OBD-II (EN): ECM/PCM Power Relay Circuit Range/Performance
Code P2510 indicates a problem with the sensor circuit of the ECM/PCM power relay – the heart of the engine's electronics. This can cause engine stalling, starting difficulties, or a complete loss of engine control. Due to the complexity of the electrical system, diagnosis by a qualified mechanic is recommended.
Symptoms
• Engine stalls unexpectedly or fails to start • Rough engine idle • Poor acceleration and loss of power • Difficulty starting the vehicle • Check Engine Light is on • Possible complete power loss to the ECM/PCM module
Possible causes
• Faulty or shorted ECM/PCM power relay • Open or short circuit in the relay sensor circuit • Defective ECM/PCM module (internal failure) • Corrosion or loose electrical harness connectors at the relay • Damaged fuse responsible for powering the control module
