(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.
