(P0116) ENGINE COOLANT TEMPERATURE SENSOR SHORT CIRCUIT (CONTINUED)

When Monitored and Set Condition

•

When Monitored: With the engine running and no fault in the throttle valve actuator.

•

Set Condition: The ECT Sensor value is more than 170°C (338°F) for more than 1 second.

POSSIBLE CAUSES

ENGINE COOLANT TEMPERATURE SENSOR SIGNAL CIRCUIT SHORT TO GROUND

ENGINE COOLANT TEMPERATURE SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE

ENGINE COOLANT TEMPERATURE SENSOR

POWERTRAIN CONTROL MODULE

For a complete Powertrain Control Module Circuit Diagram, (Refer to 9 - ENGINE - SCHEMATICS AND DIA-
GRAMS).

Diagnostic Test

1.

CHECK FOR CURRENT DTC

Turn the ignition on.

With the DRB III

T

, read PCM DTCs.

Is this DTC present?

Yes

>> For complete diagnosis of this DTC, refer to (P0116)

ENGINE COOLANT TEMPERATURE SENSOR PERFOR-
MANCE.

No

>> Go To 2

2.

INTERMITTENT WIRING AND CONNECTORS

The conditions necessary to set this DTC are not present at this time.

Note: Check connectors — Clean/repair as necessary. Poor pin to terminal connections can set DTCs. Using
the wiring diagram/schematic as a guide, inspect the wiring and connectors specific to this DTC. Wiggle the
wires while checking for shorts and open circuits.

Note: Check for any Technical Service Bulletins that may apply.

Were there any problems found?

Yes

>> Repair as necessary.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

No

>> The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for

a possible intermittent condition.
