INSPECTION

1.

INSPECT ENGINE COOLANT TEMPERATURE 
SENSOR
(a) Check the resistance.

(1) Using an ohmmeter, measure the resistance 

between the terminals.
Standard resistance

NOTICE:
If checking the engine coolant temperature 
sensor in water, be careful not to allow 
water to enter the terminals. After checking, 
wipe the water off the engine coolant 
temperature sensor.
If the result is not as specified, replace the 
engine coolant temperature sensor.

ON-VEHICLE INSPECTION

1.

INSPECT THROTTLE BODY ASSEMBLY
(a) Listen to the throttle control motor operating sounds.

(1) Turn the ignition switch to ON.
(2) When pressing the accelerator pedal, listen to 

the running sound of the motor. Make sure no 
friction noises come from the motor.
If friction noises occur, check the throttle body, 
wire harness and ECM.

(b) Check the throttle position sensor.

(1) Turn the ignition switch to ON.
(2) Turn the intelligent tester ON.
(3) Start the engine and warm it up.
(4) Select the following menu items: DIAGNOSIS / 

ENHANCED OBD II / DATA LIST / PRIMARY / 
THROTTLE POS .

(5) Depress the accelerator pedal. When the 

throttle valve is fully open, check that the 
THROTTLE POS value is within the 
specification.
Standard:

60% or more 

NOTICE:
When checking the standard throttle valve 
opening percentage, the transmission 
should be in the neutral position.
If the result is not as specified, check the 
throttle body, wire harness and ECM.
