DTC Troubleshooting: P0713 (28)

DTC P0713:
 ATF Temperature Sensor (Open)
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. Check the ATF temperature sensor voltage with the HDS in the A/T data list.
Does the ATF Temp Sensor (V) exceed 4.93 V?
YES -
Go to Step 2 .
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and the PCM.■
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the shift solenoid harness connector at the shift solenoid valve cover.
  1. Turn the ignition switch to ON (II).
  1. Measure the voltage between shift solenoid harness connector terminal No. 6 and body ground.
Is there about 5 V?
YES -
Go to Step 6 .
NO -
Go to Step 7 .

  1. Measure the voltage between shift solenoid harness connector terminals No. 6 and No. 7.
Is there about 5 V?
YES -
NO -
Repair open in the wire between PCM connector terminal B34 and the shift solenoid harness connector, then go to Step 17 .
  1. Turn the ignition switch to LOCK (0).
  1. Jump the SCS line with the HDS.
  1. Disconnect PCM connector B (49P).

  1. Check for continuity between PCM connector terminal B28 and shift solenoid harness connector terminal No. 6.
Is there continuity?
YES -
Go to Step 11 .
NO -
Repair open in the wire between PCM connector terminal B28 and the shift solenoid harness connector, then go to Step 16 .
  1. Reconnect all connectors.
  1. Start the engine in P, and wait for at least 20 seconds.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0713 indicated?
YES -
If the PCM was updated, substitute a known-good PCM, then recheck. If the PCM was substituted, go to Step 1 .
NO -
Go to Step 15 .
  1. Monitor the OBD status for P0713 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?
YES -
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. If any other DTCs were indicated on Step 14 , go to the indicated DTC's troubleshooting.■
NO -
Check for poor connections and loose terminals at the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then recheck. If the PCM was substituted, go to Step 1 . If the HDS indicates NOT COMPLETED, return to Step 13 and recheck.
  1. Connect PCM connector B (49P).
  1. Connect the ATF temperature sensor connector.
  1. Clear the DTC with the HDS.
  1. Start the engine in P, and wait for at least 20 seconds.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0713 indicated?
YES -
Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then go to Step 1 .
NO -
Go to Step 21 .
  1. Monitor the OBD status for P0713 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?
YES -
Troubleshooting is complete. If any other DTCs were indicated on Step 20 , go to the indicated DTC's troubleshooting.■
NO -
Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then go to Step 1 . If the HDS indicates NOT COMPLETED, return to Step 19 and recheck.
