DTC P0117 [ZJ, ZY, Z6]

id0102c1804000

Without Throttle Valve Actuator

DTC P0117

ECT sensor circuit low input

DETECTION CONDITION

•  The PCM monitors the ECT sensor signal. If the PCM detects that the ECT sensor voltage is less than 0.20 V, the PCM determines that the ECT sensor circuit has a malfunction.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  PENDING CODE is available if the PCM detects the above malfunction condition.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Engine overheating (Cooling system malfunction)

•  ECT sensor malfunction

•  Connect or terminal malfunction

•  Short to ground in wiring harness between ECT sensor terminal A and PCM connector terminal 2J

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY ENGINE CONDITION • Is the engine overheating?	Yes	Perform the symptom troubleshooting No.17 Cooling system concerns-Overheating procedure. (See NO.17 COOLING SYSTEM CONCERNS-OVERHEATING [ZJ, ZY, Z6].)
3	VERIFY ENGINE CONDITION • Is the engine overheating?	No	Go to the next step.
4	INSPECT ECT SENSOR CONNECTOR FOR POOR CONNECTION • Turn the ignition switch 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 terminal, then go to Step 8.
4		No	Go to the next step.
5	INSPECT ECT SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between ECT sensor terminal A (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 8.
5		No	Go to the next step.
6	INSPECT ECT SENSOR • Inspect the ECT sensor. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [ZJ, ZY, Z6].) • Is there any malfunction?	Yes	Replace the ECT sensor, then go to Step 8. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [ZJ, ZY, Z6].)
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to the next step.
7		No	Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0117 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Start the engine. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [ZJ, ZY, Z6].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [ZJ, ZY, Z6].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ZJ, ZY, Z6].)
9		No	DTC troubleshooting completed.

With Throttle Valve Actuator

DTC P0117

ECT sensor circuit low input

DETECTION CONDITION

•  The PCM monitors the input voltage from the ECT sensor. If the PCM detects that the ECT sensor voltage is less than 0.20 V, the PCM determines that the ECT sensor circuit has a malfunction.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  PENDING CODE is available if the PCM detects the above malfunction condition.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Engine overheating (Cooling system malfunction)

•  ECT sensor malfunction

•  Connect or terminal malfunction

•  Short to ground in wiring harness between ECT sensor terminal A and PCM connector terminal 2AC

•  Both ECT sensor wire are shorted each other

•  PCM malfunction
