Pinpoint Test J : Tr (Transmission Range) Sensor: Notes
WARNING: This page is about a different variant/trim than selected.
TR Sensor
Refer to TRANSMISSION CONTROLS - 6F50/6F55 Wiring Diagrams for schematic and connector information.
Normal Operation
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 Line Pressure Control (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. To aid in identifying the connectors on the solenoid body, REFER to: Transmission Description - System Operation and Component Description . .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0705 | Transmission Range Sensor A Circuit (PRNDL) Input | Mechanical or electrical fault. Input from the TR sensor did not change or is intermittent. |
| 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. |
| P0709 | Transmission Range Sensor "A" Circuit Intermittent | Mechanical or electrical fault. Input from the TR sensor did not change or is intermittent. |
| 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. |
