P1D83 FIAT – Implausible Engine Oil Temperature Signal Recieved

P1D83 FIAT Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P1D83 FIAT Possible Causes

Faulty Oil Temperature (EOT) Sensor,Oil Temperature (EOT) Sensor harness is open or shorted,Oil Temperature (EOT) Sensor circuit poor electrical connection,Faulty Powertrain Control Module (PCM)

P1D83 FIAT Description

After a calibrated amount of cool down time, the Powertrain Control Module (PCM) performs a general temperature rationality monitor and compares the AAT, ECT and IAT Sensor values. If the general temperature rationality passes, the PCM then compares the Engine Oil Temperature (EOT) Sensor value to the other temperature sensor values. If the difference is greater than a calibrated threshold, the diagnostic fails.
