2. Measure the Voltage Between Sensor Terminals
1. Place the key switch in the OFF position, unplug the accelerator
position sensor connector from the socket, and return the key
switch to the ON position again.
2. Measure the voltage between terminals (4) and (6) of
accelerator position sensor connector (at the machine wiring
harness side).
Service

4. Measure the Engine ECU Terminal Voltage
1. Place the key switch in the OFF position, and plug the
accelerator position sensor connector into the socket.
2. Place the key switch in the ON position, and measure the
voltage between engine ECU terminals V66 and V67.
Accelerator pedal fully closed: 1.35 V or lower
Service
Accelerator pedal full throttle: 4.0 V or higher
specification
Follow the OEM adjusted value : 1.1 to 1.35 V, 4.0 to 4.2 V
NOTE
• "Full close" and "Full open" are with the accelerator
position sensor, not with the accelerator pedal or hand
accelerator.
OK Check the engine ECU connectors.
OK Faulty engine ECU → Replace.
NG Replace the engine ECU connectors.
NG Go to "5. Measure the Voltage Between Sensor Terminals".
