5. CHECK COMPONENT PARTS
Check the following.

Radiator cap (Refer to CO-14, "Checking Radiator Cap" .)

Thermostat (Refer to CO-24, "THERMOSTAT AND WATER CONTROL VALVE" .)

Engine coolant temperature sensor (Refer to EC-135, "Component Inspection" .)
OK or NG
OK >> GO TO 6.
NG >> Replace malfunctioning component.
6. CHECK MAIN 12 CAUSES
If the cause cannot be isolated, go to EC-227, "
Main 12 Causes of Overheating" .
>>INSPECTION END
CHECK COOLING FAN CONTROL CIRCUIT
1. CHECK COOLILNG FAN POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connectors E6.
3. Check voltage between IPDM E/R terminal 15 and ground with
CONSULT-II or tester.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. DETECT MALFUNCTIONING PART
Check the following.

40A fusible link

Harness for open or short between IPDM E/R and battery
>> Repair open circuit or short to ground in harness or connectors.
3. CHECK COOLING FAN GROUND CIRCUIT
1. Disconnect IPDM E/R harness connectors E8, E9.
2. Check harness continuity between IPDM E/R terminal 16, 38, 60 and ground.
Refer to Wiring Diagram.
3. Also check harness for short to power.

DTC P1225 TP SENSORPFP:16119
Component DescriptionBBS005GF
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are
a kind of potentiometers which transform the throttle valve position
into output voltage, and emit the voltage signal to the ECM. In addi-
tion, these sensors detect the opening and closing speed of the
throttle valve and feed the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these sig-
nals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condi-
tion.
On Board Diagnosis LogicBBS005GG
The MI will not light up for this self-diagnosis.
DTC Confirmation ProcedureBBS005GH
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON.
5. If 1st trip DTC is detected, go to EC-230, "
Diagnostic Procedure"
.
WITHOUT CONSULT-II
1. Turn ignition switch ON.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If 1st trip DTC is detected, go to EC-230, "

CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
