DTC P0710: Problem in ATF Temperature Sensor CircuitNOTE: Record all freeze data and review General Troubleshooting Information 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 step 5.
NO - Go to step 8.
5. 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.
NO - Go to step 6.
6. Turn the ignition switch OFF.
7. Check for continuity between the No. 7 terminal of the shift solenoid harness connector and body ground.
Is there continuity?
YES - Check for poor pin fit at the NO.6 or NO.7 terminals of the shift solenoid harness connector. Update the PCM if it does not have the latest software, or substitute a know-good PCM, then recheck. If the symptom/indication goes away with a know-good PCM, replace the original PCM.
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), or repair poor ground (G101).
8. 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.
NO - Check for poor pin fit between the PCM and PCM connector terminal C14. Check for a short in the wire between PCM connector terminal C14 and the shift solenoid harness connector. If the wire is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
