AUTOMATIC TRANSMISSION (DIAGNOSTICS)(4AT) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)

DTC P0713 TRANSMISSION FLUID TEMPERATURE SENSOR CIRCUIT HIGH INPUT

DTC DETECTING CONDITION:

Input signal circuit to ATF temperature sensor is shorted.

TROUBLE SYMPTOM:

Excessive shift shock

WIRING DIAGRAM:

STEP	CHECK	YES	NO
1.CHECK HARNESS CONNECTOR BETWEEN TCM AND ATF TEMPERATURE SENSOR. 1) Turn the ignition switch to OFF. 2) Disconnect the connector from TCM. 3) Measure the resistance between TCM connector terminals. Connector & terminal (B55) No. 23 — No. 12:	Is the resistance 500 Ω or more?
2.CHECK HARNESS CONNECTOR BETWEEN TCM AND ATF TEMPERATURE SENSOR. Measure the resistance of the harness between TCM connector and chassis ground. Connector & terminal (B55) No. 23 — Chassis ground:	Is the resistance 1 MΩ or more?
3.CHECK HARNESS. Measure the resistance between TCM connector terminals while shaking the harness. Connector & terminal (B55) No. 23 — No. 12:	Does the resistance change?		Replace the TCM.
4.CHECK HARNESS CONNECTOR BETWEEN TCM AND ATF TEMPERATURE SENSOR. 1) Turn the ignition switch to OFF. 2) Disconnect the connector from transmission. 3) Measure the resistance of the harness between TCM connector and chassis ground. Connector & terminal (B55) No. 23 — Chassis ground:	Is the resistance 1 MΩ or more?		Repair the short circuit of harness between TCM and transmission harness.
5.CHECK HARNESS CONNECTOR BETWEEN TCM AND ATF TEMPERATURE SENSOR. Measure the resistance of the harness between TCM connector and chassis ground. Connector & terminal (B55) No. 12 — Chassis ground:	Is the resistance 1 MΩ or more?		Repair the short circuit of harness between TCM and transmission harness.
6.CHECK ATF TEMPERATURE SENSOR. Measure the resistance between transmission connector terminals. Connector & terminal (T4) No. 11 — No. 15:	Is the resistance 500 Ω or more?	Check for short circuits in the harness or connectors, and repair the fault location.
7.CHECK TRANSMISSION HARNESS. 1) Lift up the vehicle. 2) Drain the automatic transmission fluid. CAUTION: Do not drain ATF until it cools down. 3) Remove the oil pan. 4) Disconnect the harness connector from control valve. 5) Measure the resistance between transmission connector and transmission ground. Connector & terminal (T4) No. 11 — Transmission ground:	Is the resistance 1 MΩ or more?		Replace the transmission harness.
8.CHECK TRANSMISSION HARNESS. Measure the resistance between transmission connector and transmission ground. Connector & terminal (T4) No. 15 — Transmission ground:	Is the resistance 1 MΩ or more?		Replace the transmission harness.
9.CHECK ATF TEMPERATURE SENSOR. Measure the resistance between control valve connector terminals. Connector & terminal (AT2) No. 4 — No. 9:	Is the resistance 500 Ω or more?	Check for short circuits in the harness or connectors, and repair the fault location.	Replace the control valve body.
