C1 VERIFY TR (Transmission Range) SENSOR ALIGNMENT
- Using a scan tool, view the TRD, TRL, TRN, TRP and TRR PIDs to determine if an internal fault is present in the Transmission Range (TR) sensor, refer to the Transmission Range (TR) Sensor Diagnostic PID Chart in Transaxle Connector Layouts Transaxle Connector Layouts.
- If an electrical issue exists in the TR (Transmission Range) sensor electrical circuit, 2 or more binary positions will show 1s.
- Verify TR (Transmission Range) sensor alignment.
Is the TR (Transmission Range) sensor correctly aligned?
Yes
GO to C2.
No
ADJUST the TR (Transmission Range) sensor. TEST the system for normal operation.
C2 VERIFY SELECTOR LEVER CABLE/LINKAGE ADJUSTMENT
- Verify that the selector lever cable/linkage is correctly adjusted.
Is the selector lever cable/linkage correctly adjusted?
Yes
GO to C3.
No
ADJUST the selector lever cable/linkage REFER to Automatic Transmission/Transaxle. TEST the system for normal operation.
C3 CHECK THE TRANSAXLE POWER SUPPLY CIRCUIT

- Ignition ON.
- Measure the voltage between TR (Transmission Range) sensor C167 pins 2, 3, 4, 5, 7 and 8 and ground using the following table:
TR (Transmission Range) Sensor Circuit TR (Transmission Range) Sensor C167 Pin Ground 15S-TA37A (GN/YE) Park C167-5 Ground 15-TA42 (GN/WH) M1 C167-3 Ground 15-TA41 (GN/OG) M2 C167-7 Ground 15S-TA40 (GN/BK) Drive C167-2 Ground 15S-TA38 (GN/BU) Reverse C167-4 Ground 15S-TA39 (GN/RD) Neutral C167-8 Ground
Is any voltage present?
Yes
REPAIR the circuit(s) for a short to power.
No
GO to C6.
C6 CHECK THE VEHICLE HARNESS FOR A SHORT TO GROUND
- Measure the resistance between TR (Transmission Range) sensor C167 pins 2, 3, 4, 5, 7 and 8 and ground using the following table:
TR (Transmission Range) Sensor Circuit TR (Transmission Range) Sensor C167 Pin Ground 15S-TA37A (GN/YE) Park C167-5 Ground 15-TA42 (GN/WH) M1 C167-3 Ground 15-TA41 (GN/OG) M2 C167-7 Ground 15S-TA40 (GN/BK) Drive C167-2 Ground 15S-TA38 (GN/BU) Reverse C167-4 Ground 15S-TA39 (GN/RD) Neutral C167-8 Ground
Is the resistance greater than 10,000 ohms?
Yes
GO to C7.
No
REPAIR the circuit(s) for a short to ground. TEST the system for normal operation.
C7 CHECK TR (Transmission Range) SENSOR CIRCUITRY FOR AN OPEN CIRCUIT
- Measure the resistance between TR (Transmission Range) sensor C167 pins 2, 3, 4, 5, 7 and 8 and the corresponding PCM C175T pin.
TR (Transmission Range) sensor Circuit TR (Transmission Range) C167 Pin PCM Connector C175T Pin 15S-TA37A (GN/YE) Park 5 8 15-TA42 (GN/WH) M1 3 13 15-TA41 (GN/OG) M2 7 14 15S-TA40 (GN/BK) Drive 2 20 15S-TA38 (GN/BU) Reverse 4 35 15S-TA39 (GN/RD) Neutral 8 41
