Removal & Installation
1. Disconnect the negative battery cable.
2. Remove the engine cover.
3. Drain the cooling system (See Cooling System Draining and Filling in Section 06 Cooling).
WARNING!
Always allow the engine to cool before opening the cooling system. Do not loosen the coolant pressure relief
cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and
hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may
result in serious personal injury.
4. Remove the coolant fan & radiator assembly (See Coolant Fan & Radiator Assembly Removal & Installation in
Section 06 Cooling).

Engine Coolant Temperature (ECT) Sensor
Description
The Engine Coolant Temperature (ECT) sensor threads into the coolant outlet connector. The ECT is a negative
thermal coefficient sensor.
Operation
The ECT provides an input to the Engine Control Module (ECM). As temperature increases, resistance of the sensor
decreases. As coolant temperature varies, the ECT sensor resistance changes resulting in a different voltage value
at the ECT sensor signal circuit. The ECM uses the input to control air-fuel mixture, timing, A/C compressor and
radiator fan on/off times.
Removal & Installation
1. Disconnect the negative battery cable.
2. Drain the cooling system (See Cooling System Draining Procedure in Section 06 Cooling System).
WARNING!
Never remove the pressure relief cap under any conditions while the engine is operating or hot. Failure to follow
these instructions could result in personal injury or damage to the cooling system or engine. To avoid having
scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pressure
relief cap. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it
slowly one turn (counterclockwise). Step back while the pressure is released from the cooling system. When you
are certain all the pressure has been released, (with a cloth) turn and remove the pressure relief cap. Failure to
follow these instructions may result in serious personal injury.
3. Disconnect the coolant temperature sensor electri-cal connector.
CAUTION:
Remove the coolant temperature sensor when
the engine is cold.
4. Remove the engine coolant temperature sensor(1).
(Tighten: Engine coolant temperature sensor to 20
N·m)
5. Discard the O-ring.

Engine Coolant Temperature (ECT) Sensor
Description
The Engine Coolant Temperature (ECT) Sensor is beside the thermostat. The ECT Sensor is a negative thermal
coefficient sensor.

The ECT sensor provides an input signal to the ECM. As temperature increases, resistance of the sensor decreases.
As coolant temperature varies, the ECT sensor resistance changes resulting in a different voltage value at the ECT

Removal & Installation
1. Disconnect and isolate the negative battery cable.
2. Release the coolant system pressure.
WARNING!
Never remove the radiator pressure relief cap under any conditions while the engine is operating or hot. Failure
to follow these instructions could result in personal injury or damage to the cooling system or engine. To avoid
having scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pres-
sure relief cap. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn

The following conditions apply to this symptom:
•The engine has poor performance.
• The engine has poor acceleration.
1.PRELIMINARY CHECKS
• Verify symptom is reported under normal driving conditions without excessive engine/vehicle load conditions.
• Carry out the following preliminary checks:
Fuel quality
Vacuum lines (check for damage and correct routing)
Intake air system (check for damaged tubes and dirty air filter)
Vehicle wiring (disconnected, corroded/damaged)
Throttle linkage
Radiator (obstructed)
Transaxle
NOTE :
Be aware of the over RPM limiting functions of the ECM.
Are all checks OK?
Ye s>>Go to the next step.
No
>>Repair as necessary.
Verify the symptom no longer exists.
2.CHECK ECM DTC
• Turn ignition switch on.
• With the scan tool X-431, read the DTC.
Do any DTC displayed on the scan tool?
Ye s>>See the Diagnostic Trouble Code (DTC) List.
Go to the specific diagnostic test to troubleshoot the DTC.
No
>>Go to the next step.
3.CHECK FUEL SYSTEM PRESSURE
• Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).
• Check fuel system pressure (See Fuel Pressure Test in Section 04 Fuel Delivery).
Is fuel pressure correct?
Ye s>>Go to the next step.
No
>>If the fuel pressure is greater than 400 kPa (4.0 bar):
Replace the fuel pressure regulator.
If the fuel pressure is less than 400 kPa (4.0 bar):
Check the fuel supply system for restrictions or leaks.
If no problems, repair or replace fuel filter, pressure regulator or fuel pump assembly.
