P0217 ENGINE OVER TEMPERATURE

DTC Logic

INFOID:0000000001102011

DTC DETECTION LOGIC

If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

Diagnosis Procedure

INFOID:0000000001102013

1.

CHECK COOLING FAN LOW SPEED FUNCTION

1.

Start engine and let it idle.

2.

Turn air conditioner switch and blower fan switch ON.

3.

Make sure that cooling fan operates at low speed.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Refer to 

EC-1422, "Diagnosis Procedure"

.

2.

CHECK COOLING FAN HIGH SPEED FUNCTION

1.

Turn ignition switch OFF.

2.

Turn air conditioner switch and blower fan switch OFF.

3.

Disconnect engine coolant temperature sensor harness connector.

4.

Connect 150

Ω

 resistor to engine coolant temperature sensor harness connector.

5.

Restart engine and make sure that cooling fan operates at higher speed than low speed.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Refer to 

EC-1422, "Diagnosis Procedure"

.

3.

CHECK COOLING SYSTEM FOR LEAK-I

Check cooling system for leak. Refer to 

CO-52, "Inspection"

.

Is leakage detected?

YES

>> GO TO 4.

NO

>> GO TO 5.

4.

CHECK COOLING SYSTEM FOR LEAK-II

Check the following for leak. Refer to 

CO-52, "Inspection"

.

• Hose
• Radiator
• Water pump

>> Repair or replace malfunctioning part.

5.

CHECK RADIATOR CAP

DTC No.

Check radiator cap. Refer to 

CO-55, "RADIATOR CAP : Inspection"

.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Replace radiator cap.

6.

CHECK THERMOSTAT

Check thermostat. Refer to 

CO-62, "Removal and Installation"

.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Replace thermostat.

7.

CHECK ENGINE COOLANT TEMPERATURE SENSOR

Refer to 

EC-1344, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> Replace engine coolant temperature sensor.

8.

CHECK MAIN 12 CAUSES

If the cause cannot be isolated, check the following.

*1: Engine running at idle speed.

*2: Engine running at 3,000 rpm for 10 minutes.

*3: Drive at 90 km/h (55 MPH) for 30 minutes and then let idle for 10 minutes.

*4: After 60 minutes of cool down time.

P0225 APP SENSOR

P0225 APP SENSOR

Description

INFOID:0000000001090480

The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensors detect the accelera-
tor pedal position and sends a signal to the ECM. The ECM uses the
signal to determine the amount of fuel to be injected.

DTC DETECTION LOGIC

NOTE:
• If DTC P0225 is displayed with DTC P0641, first perform trouble diagnosis for DTC P0641. Refer to

EC-1393, "DTC Logic"

.

• If DTC P0225 is displayed with DTC P0651, first perform trouble diagnosis for DTC P0651. Refer to

EC-1395, "DTC Logic"

.

• If DTC P2120 is present at the same time, check that the APP sensor connector is connected cor-

rectly.

• Conditions for applying the diagnostic procedure to the stored DTCs: 
- The DTC is declared present after a series of full load/no load action on the accelerator.
• If the DTC is present:
- Malfunction indicator (Red) lights up.

GI-41, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK ACCELERATOR PEDAL POSITION SENSOR POWER SUPPLY CIRCUIT

1.

Disconnect accelerator pedal position sensor harness connector.

2.

Turn ignition switch ON.
