Allison WTEC II Fault Code: 62 PID: SPN: 23 FMI: Retarder oil temperature sensor, failed high

Main code 62 indicates the retarder temperature sensor or circuitry is providing a signal outside the usable range of the ECU. Retarder temperature sensor failed high (178?C; 352?F)

Main code 62 can be the result of a hardware failure or an actual extremely high or low temperature condition.

NOTE: A combination of codes 62 23, 33 23, and 21 23 indicates a problem with one of the branches of the common ground wire (wire 135) between the throttle and temperature sensors.
