DTC Troubleshooting: P0712 (28)

DTC P0712:
Short in ATF Temperature Sensor Circuit
NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information.
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Turn the ignition switch to ON (II).

1. Check the ATF Temp Sensor voltage in the Data List with the HDS.

Is the ATF Temp Sensor voltage 0.07 V or less?

YES | - | Go to Step 3 .
NO | - | Intermittent failure, the system is OK at this time. Check for an intermittent short to body ground in the ATFT wire between the ATF temperature sensor and the PCM.■

1. Turn the ignition switch to LOCK (0).

1. Disconnect the shift solenoid wire harness connector.

1. Turn the ignition switch to ON (II).

1. Check the ATF Temp Sensor voltage in the Data List with the HDS.

Is the ATF Temp Sensor voltage 0.07 V or less?

YES | - | Go to Step 7 .
NO | - | Replace the ATF temperature sensor, then go to Step 12 .

1. Turn the ignition switch to LOCK (0).

1. Jump the SCS line with the HDS.

1. Disconnect PCM connector; R20A3 engine model: B (44P), K24Z3 engine model: B (49P).

1. Check for continuity between shift solenoid wire harness connector terminal No. 6 and body ground.

Is there continuity?

YES | - | Repair short to body ground in the wire between PCM connector terminal; R20A3 engine model: B27, K24Z3 engine model: B28 and shift solenoid wire harness connector terminal No. 6, then go to Step 12 .
NO | - | Go to Step 11 .
