ACCELERATOR POT (THROTTLE SENSOR) TESTING
PROCEDURES
STEP DETAILS
Make sure vehicle safe. Turn ignition switch off and remove key.
Set parking brake.
Check resistance of pot. See Figure 5-5. Disconnect pot from harness and take
measurements on pot side of connection while
depressing accelerator. Pin numbers are on the
connector.
Pin 1 to pin 3………… 5 k ohms at all times.
Pin 1 to pin 2………… 15 k ohms to 10 k ohms.
Pin 2 to pin 3………… 10 k ohms to 15 k ohms.
Measure continuity. See Figure 5-6. Of combined harness and pot circuit. Plug pot
connector into main harness.
Measure resistance from pin 27 to pin 28 on the
large controller connector. When accelerator is
depressed resistance should go from 15 k ohms
to 10 k ohms.
Measure from pin 28 to pin 29. Resistance
should go from 10 k ohms to 15 k ohms.
Measure from pin 27 to pin 29. Resistance
should stay at 5 k ohms.
If resistances are correct then pot and harness
are ok. If resistances different than those
shown, proceed to next step.
What to do??? If entire harness and pot check good, problem
must be somewhere else.
If pot is good and harness and pot showed bad,
must be fault in harness.
If pot readings not correct, change pot.
