DTC P0710:  Problem in ATF Temperature Sensor Circuit

NOTE: Record all freeze data before you troubleshoot.

1.Turn the ignition switch OFF.

2.Disconnect the shift solenoid harness connector.

3.Turn the ignition switch ON (II).

4.Measure the voltage between the No. 6 terminal of the shift solenoid harness connector and body ground.

 

Is there about 5 V?


YES - Go to 5.


NO - Go to 15.

5.Turn the ignition switch OFF.

6.Disconnect the battery nagative terminal.

7.Disconnect PCM connector A (31P).

8.Check for continuity between the No. 7 terminal of the shift solenoid harness connector and body ground.

 

Is there continuity?


YES - Repair short in the wire between PCM connector terminal A10 and the shift solenoid harness connector.n


NO - Go to 9.


9.Connect PCM connector A (31P).

10.Connect the battery nagative terminal.

11.Turn the ignition switch ON (II).

12.Measure the voltage between the No. 6 and No. 7 terminals of the shift solenoid harness connector.

 

Is there about 5 V?


YES - Check the ATF temperature sensor and shift solenoid harness in the transmission housing.n


NO - Go to 13.


13.Turn the ignition switch OFF.

14.Check for continuity between the No. 7 terminal of the shift solenoid harness connector and body ground.

 

Is there continuity?


YES - Check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.n


NO - Repair open in the wire between PCM connector terminal A10 and the shift solenoid harness connector, or between PCM connector terminals A23 and ground ( G101), between A24 and ground (G101), and repair poor ground (G101).n

15.Measure the voltage between PCM connector terminal C14 and body ground.

 

Is there about 5 V?


YES - Repair open in the wire between PCM connector terminal C14 and the shift solenoid harness connector.n


NO - Check for a short in the wire between PCM connector terminal C14 and the shift solenoid harness connector. If the wire is OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.n
