(P0116) ENGINE COOLANT TEMPERATURE SENSOR PERFORMANCE (CONTINUED)
5.
ECT SENSOR SIGNAL CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect PCM C3 harness connector.
Note: Check connectors — Clean/repair as necessary.
Measure the resistance between ground and ECT Sensor Signal cir-
cuit.
Is the resistance above 100 kohms?
Yes >> Go To 6
No >> Repair the ECT Sensor Signal circuit for a short to ground.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
6.
ECT SENSOR SIGNAL CIRCUIT SHORT TO SENSOR GROUND CIRCUIT
With the ignition off.
Measure the resistance between the ECT Sensor Signal circuit and
the Sensor Ground circuit at the ECT Sensor harness connector.
Is the resistance above 100 kohms?
Yes >> Replace and program the Powertrain Control Module.
(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/POWERTRAIN
REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No >> Repair the ECT Sensor Signal circuit for a short to the
Sensor Ground circuit.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
7.
ENGINE COOLANT TEMPERATURE SENSOR
Turn the ignition off.
Disconnect the ECT Sensor harness connector.
Note: Check connectors — Clean/repair as necessary.
Turn the ignition on.
Connect a jumper wire between the ECT Sensor Signal circuit and the
ECT Sensor Ground circuit at the ECT Sensor harness connector.
With the DRB III , monitor the ENG COOLANT TEMP value.
Is the value at or above 170°C (338°F)?
Yes >> Replace the Engine Coolant Temperature Sensor. (Refer
to 7 - COOLING/ENGINE/ENGINE COOLANT TEMP
SENSOR - REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No >> Go To 8
