Throttle Sensor Output Voltage
Connections to Sensor
Meter (+) → G/W lead
Meter (–) → BK/W lead
Meter (–) → BK/W lead
•
Measure the sensor output voltage with the idle speed.

CAUTION
Never drop the throttle sensor, especially on a hard
surface. A shock to the sensor can damage it.

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).
