DTC Troubleshooting: P0713 (28-4)

DTC P0713:  Open in ATF Temperature Sensor Circuit


NOTE:

1.Check ATF temperature sensor voltage with the Honda PGM Tester or HDS in the A/T data list.

Does ATF temperature sensor voltage exceed 4.84 V?


YES - Go to 2.


NO - Intermittent failure, the system is OK at this time.n


2.Turn the ignition switch OFF.

3.Disconnect the shift solenoid harness connector.

4.Turn the ignition switch ON (II).

5.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 6.


NO - Go to 7.

6.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 - Repair open in the wire between PCM connector terminal A23 and the shift solenoid harness connector.n


7.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 loose or poor connections at PCM connector terminal C14. If the connections are 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.n
