DTC P062C
DTC P062C: Internal Module Vehicle Speed Performance
General Description
The dual speed sensor is integrated to the sensor unit in the transmission. If the transmission control module (TCM) judges that the calculations to the speed from the pulse signals of dual speed sensor (input speed) and dual speed sensor (output speed) are not valid, the TCM detects a malfunction and stores a DTC.

Malfunction Threshold
The TCM judges that the calculations to the speed from the pulse signals of dual speed sensor (input speed) and dual speed sensor (output speed) are not valid.
Possible Cause
The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- Dual speed sensor NM line open (includes a loose or disconnected connector)
- Dual speed sensor NOUT line open (includes a loose or disconnected connector)
- Dual speed sensor VCC2 line open (includes a loose or disconnected connector)
- Dual speed sensor NM line short to ground
- Dual speed sensor NOUT line short to ground
- Dual speed sensor VCC2 line short to ground
- Sensor unit failure (dual speed sensor)
- TCM internal failure
Confirmation Procedure
Operating Condition
Start the engine, and wait few seconds.
With the HDS
None.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the A/T gear position indicator blinks, the MIL comes on, and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the TCM memory.
Conditions for clearing the DTC
The A/T gear position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
