Subthrottle Sensor (Service Code 32)
After subthrottle sensor voltage inspection, remove the
If the reading is out of the standard range, inspect the
throttle sensor resistance.
If the output voltage is normal, check the wiring for conti-
nuity (see next diagram).
Turn the ignition switch OFF.
Disconnect the subthrottle sensor connector.
Connect a digital meter [A] to the subthrottle sensor con-
Measure the main throttle sensor resistance.
Throttle Sensor Resistance
If the reading is out of the range, replace the throttle body
If the reading is within the range, but the problem still
exists, replace the ECU (see this chapter).
