Key Switch Test – Engine Kill Circuit
TEST PROCEDURE 7 – Throttle Position Sensor (TPS)
The throttle position sensor performs the function of two limit switches: the accelerator pedal limit switch and the kill
limit switch. This sensor is sealed and is not to be repaired or replaced. If sensor is determined to need replacing
through test procedures found in this manual, the accelerator pedal assembly must be replaced.
The sensor is joined to the main wire harness through a six-pin connector. Tests for
the sensor are found in the following two procedures.
Accelerator Pedal Limit Switch Function
See General Warnings on page 1-2.
The green and orange wires connect to the accelerator pedal limit switch function of the throttle position sensor. This is
the normally open (NO) portion of the circuit used to energize the starter solenoid.
NOTE:
Keep the battery connected while performing this test procedure.
1.
Place the neutral lockout switch in the MAINTENANCE position, put the Forward/Reverse handle in the
NEUTRAL position, and chock the wheels.
2.
Disconnect the spark plug wire from the spark plug.
3.
Disconnect gray 18-pin connector from ECU.
4.
With battery connected and using a multimeter set to the diode test function (ç), attach the red (+) lead to the
orange wire at the starter solenoid and the black (-) lead to the green wire at the limit switch located on the
Forward/Reverse shifter assembly.
See following NOTE.
NOTE:
It may be necessary to partially pull the green wire from the switch terminal to attach the black lead.
5.
Turn the key switch to the ON position. With accelerator pedal at rest in the fully raised position, the meter
should indicate an over limit (no continuity) condition.
6.
Press the accelerator to engage the starter and engine. With accelerator pedal pressed, the meter should
indicate approximately 1.0 volt. If either reading is incorrect, replace the accelerator pedal assembly.
