CHECK Engine (Turbo
1. Check to be sure that the engine coolant tempera ture
is
or below.
NOTE
Disconnecting the engine coolant temperature sensor
connector and connecting the harness-side of the co nnec-
tor to another engine coolant temperature sensor th at
is at
or below is also okay.
2. Check that the operation sound of the stepper mo tor
can be heard after the ignition is ON (but without
starting the motor), then
3.If the operation sound cannot be heard, check the
motor’s activation circuit.
If the circuit is normal, it is probable that there, is

1. Do not disassemble the sensor and motor.
2.Do not immerse solvent to clean the sensor and moto r.
Clean then with shop towel.
REMOVAL
1. Do not remove the throttle valve.
2. Check if the vacuum port or passage is clogged. Use
compressed air to clean the vacuum passage.

(3) Check for continuity between terminals No. 3 (c losed
throttle position switch) and No. 4 (ground).
If not continuity with the throttle valve fully close d,
turn the throttle position sensor counterclockwise, and
then check again.

Caution
Make sure that the fuel gauge unit and pump assembl y

together with the cap when tightening the cap.
If the mating marks are not aligned, the position o f the
