TEST PROCEDURE 4 – Throttle Position Sensor Voltage
See General Warnings on page 1-1.
The accelerator position, which is proportional to the sensor voltage, can be displayed with the IQDM handset. If an
IQDM handset is not available, proceed to
Throttle Position Sensor Voltage Test without the IQDM Handset .
Throttle Position Sensor Voltage Test with the IQDM Handset
1. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position jack stands
under the frame rails just forward of each spring mount.
See WARNING “Lift only one end...” in General
Warnings on page 1-1. See also following WARNING.
WARNING
• The key switch should be placed in the OFF position and left in the OFF position for the duration
of this test.
2. Connect the IQDM to the vehicle.
3. Access the Test menu and select THROTTLE % by using the SCROLL DISPLAY buttons.
4. The IQDM should indicate 0 % with the pedal not pressed. While monitoring the IQDM display screen, slowly
press the accelerator pedal. As the pedal is pressed, the IQDM should indicate a rise from 0 % (pedal not
pressed) to 100 % (pedal fully pressed).
5. If the throttle position sensor does not operate as described in previous step, proceed to Throttle Position
Sensor Voltage Test without the IQDM Handset .
Throttle Position Sensor Voltage Test without the IQDM Handset
1. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position jack
stands under the frame rails just forward of each spring mount.
See WARNING “Lift only one end...” in
General Warnings on page 1-1.
2. With key switch OFF and batteries connected, place Tow/Run switch in RUN. Using a multimeter set to 200 volts
DC, place red (+) probe on battery no. 1 positive post and place black (–) probe (with insulation-piercing probe)
on the purple/white wire at a point close to the six-pin connector at the throttle position sensor. The reading should
be approximately 48-50 volts (full battery voltage).
3. If reading is zero volts, check the purple/white wire continuity from the six-pin connector at the sensor to the
16-pin connector at the speed controller. Check terminal positions in six-pin connector at the sensor and the
16-pin connector. If all of the continuity readings are correct and the connectors are wired correctly, replace the
speed controller.
