Transmission Range (TR) Position Sensor Assembly
The transmission range (TR) position sensor assembly is an internally mounted sensor that includes the detent spring, rooster comb and bracket, located next to the solenoid body. The components of the TR position sensor are factory adjusted to each other and the sensor must be installed as a calibrated assembly. The TR position sensor contains electronic circuitry that provides the PCM a fixed frequency at a duty cycle for each of the various positions of the manual lever (PARK, REVERSE, NEUTRAL, DRIVE, M3, M2 and M1) to the PCM. The PCM uses the TR position sensor signal for engine functions (start, reverse lamps) and for line pressure control, shift scheduling and TCC operation.

Diagnosing an electronically controlled automatic transmission is simplified by using the following procedures. One of the most important things to remember is that there is a definite procedure to follow. DO NOT TAKE SHORT CUTS OR ASSUME THAT CRITICAL CHECKS OR ADJUSTMENTS HAVE ALREADY BEEN MADE. Follow the procedures as written to avoid missing critical components or steps. By following the diagnostic sequence, the technician will be able to diagnose and repair the concern the first time.
On-Board Diagnostics with Scan Tool
NOTE: For detailed instruction and other diagnostic methods using the scan tool, refer to the tester manual and the Powertrain Control/Emissions Diagnosis (PC/ED) manual.
These quick tests should be used to diagnose the PCM and should be carried out in order.
- Quick Test 1.0-Visual Inspection
- Quick Test 2.0-Set Up
- Quick Test 3.0-Key On, Engine Off
- Quick Test 4.0-Continuous Memory
- Quick Test 5.0-Key On, Engine Running
- Special Test Mode
- Wiggle Test
- Output Test Mode
- PCM Reset Mode
- Clearing DTCs
- OBD II Drive Cycle
- For further information on other diagnostic testing features using the scan tool, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual. Other diagnostic methods include the following.
- Parameter Identification (PID) Access Mode
- Freeze Frame Data Access Mode
- Oxygen Sensor Monitor Mode

P0706
TR Sensor
TR sensor frequency fault detected.
TR sensor signal frequency is out of normal range.
Only REVERSE, NEUTRAL and 5th gear detected. Engine may not crank.
For gasoline engine vehicles, Go To Pinpoint Test C . For diesel engine vehicles, Go To Pinpoint Test H .
P0707
TR Sensor
TR sensor circuit duty cycle low input.
TR sensor signal duty cycle is below threshold, sensor/circuit electrical malfunction.
Only REVERSE, NEUTRAL and 5th gear detected. Engine may not crank.
For gasoline engine vehicles, Go To Pinpoint Test C . For diesel engine vehicles, Go To Pinpoint Test H .
