Pinpoint Test J : DTCS P0706, P0707, P0708, P1702, P1705, P1921: Notes
Refer to Transmission Controls - MPS6 for schematic and connector information.
Normal Operation and Fault Conditions
The TR sensor provides a fixed frequency duty cycle to the PCM for each manual control lever positions (PARK, REVERSE, NEUTRAL, DRIVE and LOW). The PCM uses the TR sensor signal for LPC, shift scheduling and TCC operation. The PCM transmits TR data on the High Speed (HS) CAN to the BCM for engine start and reverse lamp operation.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0706 | Transmission Range Sensor "A" Circuit Range/Performance | Mechanical or electrical fault. Input from the TR sensor did not change or is intermittent. |
| P0707 | Transmission Range Sensor "A" Circuit Low | TR sensor circuit open or short to ground. |
| P0708 | Transmission Range Sensor "A" Circuit High | TR sensor circuit open. |
| P1702 | Transmission Range Sensor "A" Circuit Intermittent | TR sensor circuit open or short to ground. |
| P1705 | Transmission Range Sensor Not Indicating Park/Neutral During Self-Test | TR sensor misaligned or in wrong position during the self-test. |
| P1921 | Transmission Range Signal | The PCM has detected a TR signal duty cycle out of range. |
