P0127F-FUEL PUMP CONTROL CIRCUIT 2 OVERCURRENT (TIPM)
For a complete wiring diagramRefer to Section 8W.

When Monitored:
With the ignition on. Battery voltage greater than 10.4 volts. TIPM requesting Fuel Pump operation.
Set Condition:
An overcurrent condition is detected in the fuel pump control output circuit. One Trip Fault. Three good trips to
turn off the MIL.
Possible Causes
TERMINAL DAMAGE OR CORROSION
FUEL PUMP MOTOR GROUND HIGH RESISTANCE
(A109) FUEL PUMP CONTROL OUTPUT CIRCUIT HIGH RESISTANCE
FUEL PUMP MOTOR
TIPM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.FUEL PUMP OPERATION
Ignition on, engine not running.
With a scan tool in the TIPM Actuators, actuate the Fuel Pump.
Is the Fuel Pump operating?
Ye s>>
Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No>>

2.VISUAL AND PHYSICAL CONNECTOR AND TERMINAL INSPECTION
Turn the ignition off.
Disconnect the C10 TIPM harness connector.
Disconnect the Fuel Pump Module harness connector.
Inspect the terminal and connector condition. Check for signs of corrosion build up or damage the would compro-
mise the terminal to controller pin connector.
NOTE: Make sure that all in-line connectors are inspected for corrosion and/or damage.
Visually inspect the wiring harness. Look for any chafed, pierced, pinched or partially broken wires hidden in the
wire insulation.
Were any of the above conditions found?
Ye s>>
Repair or replace as necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

P1281-ENGINE IS COLD TOO LONG
For a complete wiring diagramRefer to Section 8W.
When Monitored:
The ignition key on, engine running.
Set Condition:
The engine does not warm to 176 Deg. F while driving for 20 minutes after start.
Possible Causes
ENGINE COLD TOO LONG
ECT SENSOR OPERATION
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
1.CHECK COOLING SYSTEM PERFORMANCE
NOTE: The best way to diagnose this DTC is to allow the vehicle to remain outside overnight in order to
have a completely cold soaked engine.
NOTE: Extremely cold outside ambient temperatures may cause this DTC to set.
Verify that the coolant level is not low and correct as necessary.
Start the engine.
With the scan tool, set the engine RPM to 1500 and allow the engine to warm up for 10-15 minutes.
With the scan tool, monitor the ENG COOLANT TMP DEG value during the warm up cycle. Make sure the transition
of temperature change is smooth.
Did the engine temperature reach a minimum of 80° C (176° F)?
Ye s>>
Go To 2
No>>
Refer to the Service Information for cooling system performance diagnosis. The most probable cause is
a Thermostat problem. Also, refer to any related TSBs.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2.ECT SENSOR OPERATION
WARNING: WARNING: MAKE SURE THE ENGINE COOLING SYSTEM IS COOL BEFORE REMOVING THE
PRESSURE CAP OR ANY HOSE. SEVERE PERSONAL INJURY MAY RESULT FROM ESCAPING HOT COOL-
ANT. THE COOLING SYSTEM IS PRESSURIZED WHEN HOT.
With the scan tool, read and record the ECT Sensor Temperature value.
Using the DRB Temperature Probe #CH7050, measure the engine coolant temperature.
NOTE: The t-stat housing area should be around 192-195 at start to open.
Is the ECT Sensor value with -15°C (5°F) of the temperature probe reading?
Ye s>>
Te s t C o m p l e t e .
No>>
Replace the ECT Sensor.
Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
