DTC P0117:00 DIAGNOSTIC PROCEDURE

STEP INSPECTION ACTION
1 VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAVE BEEN RECORDED
  • Have the FREEZE FRAME DATA (Mode 2)/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS (engine cooling system related) been recorded?
Yes Go to the next step.
No Record the FREEZE FRAME DATA (Mode 2)/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS on the repair order, then go to the next step.
2 VERIFY RELATED REPAIR INFORMATION AVAILABILITY
  • Verify related Service Bulletins and/or on-line repair information availability.
  • Is any related repair information available?
Yes Perform repair or diagnosis according to the available repair information.
  • If the vehicle is not repaired, go to the next step.
No Go to the next step.
3 VERIFY ENGINE CONDITION
  • Verify the engine condition.
  • Is the engine overheating?
Yes Perform the symptom troubleshooting "NO. 17 COOLING SYSTEM CONCERNS-OVERHEATING".
(See NO. 17 COOLING SYSTEM CONCERNS-OVERHEATING .)
No Go to the next step.
4 INSPECT ECT SENSOR CONNECTOR CONDITION
  • Switch the ignition to off.
  • Disconnect the ECT sensor connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Is there any malfunction?
Yes Repair or replace the connector and/or terminals, then go to Step 9.
No Go to the next step.
5 CLASSIFY ECT SENSOR MALFUNCTION OR WIRING HARNESS MALFUNCTION
  • Reconnect all disconnected connectors.
  • Access the ECT PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .)
  • Verify the ECT PID value when disconnecting the ECT sensor connector.
  • Does the ECT PID value change?
Yes Replace the ECT sensor, then go to Step 9.
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION .)
No Go to the next step.
6 INSPECT ECT SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
  • Verify that the ECT sensor connector is disconnected.
  • Switch the ignition to off.
  • Inspect for continuity between ECT sensor terminal A (wiring harness-side) and body ground.
  • Is there continuity?
Yes If the short to ground circuit could be detected:
  • Repair or replace the wiring harness for a possible short to ground.

If the short to ground circuit could not be detected:

Go to Step 9.
No Go to the next step.
7 INSPECT PCM CONNECTOR CONDITION
  • Disconnect the PCM connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Is there any malfunction?
Yes Repair or replace the connector and/or terminals, then go to Step 9.
No Go to the next step.
8 INSPECT ECT SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER
  • Verify that the ECT sensor and PCM connectors are disconnected.
  • Inspect for continuity between ECT sensor terminals A and B (wiring harness-side).
  • Is there continuity?
Yes Repair or replace the wiring harness for a possible short to each other, then go to the next step.
No Go to the next step.
9 VERIFY DTC TROUBLESHOOTING COMPLETED
  • Make sure to reconnect all disconnected connectors.
  • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE .)
  • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST .)
  • Is the same DTC present?
Yes Repeat the inspection from Step 1.

Go to the next step.
No Go to the next step.
10 VERIFY AFTER REPAIR PROCEDURE
Yes Go to the applicable DTC inspection.
(See DTC TABLE .)
No DTC troubleshooting completed.
