YES NO
LG1 (BRN/YEL) LG2 (BRN/YEL) PCM CONNECTOR C (44P)
Problem in Output Shaft (Countershaft) Speed Sensor Circuit (No Signal Input)
NOTE:
• Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information (see page 14-5).
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
1. Clear the DTC with the HDS.
2. Check for proper output shaft (countershaft) speed sensor installation (see page 14-246).
3. 4WD model: Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely.
2WD model: Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle.
4. Start the engine, and turn the VSA off for model equipped with VSA (the light on the VSA OFF switch comes on). Run the vehicle in the D position with engine speed 2,000 rpm (min ) or higher for more than 10 seconds. Slow down and stop the wheel.
5. Monitor the OBD STATUS for P0722 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Go to step 6.
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the output shaft (countershaft) speed sensor and the PCM. If the HDS indicates NOT COMPLETED, return to step 4 and recheck.
6. Turn the ignition switch OFF.
7. Jump the SCS line with the HDS.
8. Disconnect PCM connector C (44P).
9. Check for continuity between PCM connector terminals C40 and body ground, and between C44 and body ground.
Go to step 10.
Repair open in the wires between PCM connector terminals C40, C44 and ground (G101), or repair poor ground (G101), then go to step 36.

Go to step 18.
Go to step 14.
15. Disconnect PCM connector C (44P).
16. Check for continuity between PCM connector terminal C13 and output shaft (countershaft) speed sensor connector terminal No. 1.
Go to step 17.
Repair open in the wire between PCM connector terminal C13 and the output shaft (countershaft) speed sensor, then go to step 36.
17. Check for continuity between PCM connector terminal C13 and body ground.
Repair short in the wire between PCM connector terminal C13 and the output shaft (countershaft) speed sensor, then go to step 36.

software (see page 14-9), or substitute a known-good PCM (see page 14-10).
33. Start the engine, and turn the VSA off for model equipped with VSA (the light on the VSA OFF switch comes on). Run the vehicle in the D position with engine speed 2,000 rpm (min ) or higher for more than 10 seconds. Slow down and stop the wheel.
34. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
If the PCM was updated, substitute a known-good PCM (see page 14-10), then recheck. If the PCM was substituted, go to step 1.
If DTC P0722 is not indicated, or if any other DTCs are indicated, go to step 35.
35. Monitor the OBD STATUS for P0722 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM; R20A1 and R20A2 engine models (see page 11-226), K24Z1 engine model (see page 11-613). If any other DTCs were indicated on step 34, go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor connections and loose terminals at the output shaft (countershaft) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see page 14-10), then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, keep idling until a result comes on.
36. Clear the DTC with the HDS.
37. Start the engine, and turn the VSA off for model equipped with VSA (the light on the VSA OFF switch comes on). Run the vehicle in the D position with engine speed 2,000 rpm (min ) or higher for more than 10 seconds. Slow down and stop the wheel.
38. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
Check for poor connections and loose terminals at the output shaft (countershaft) speed sensor and the PCM, then go to step 1.
If DTC P0722 is not indicated, or if any other DTCs are indicated, go to step 39.
39. Monitor the OBD STATUS for P0722 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Troubleshooting is complete. If any other DTCs were indicated on step 38, go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor connections and loose terminals at the output shaft (countershaft) speed sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 37 and recheck.
