Damaged sensor Most likely a bad ECT sensor, but it requires diagnosis. The code is only telling you that at some point the PCM got a faulty reading on the ECT circuit. You need to find out what part of the circuit caused that reading, it could be the sensor, the connector at the sensor, the wiring between the sensor and the PCM, or the PCM itself.
