PEDAL POTENTIOMETER CIR-
CUIT TRACK 2
(Throttle/pedal position sensor/
switch “D” circuit)
• 1.DEF: VOLTAGE TOO LOW
• 2.DEF: VOLTAGE TOO HIGH
• An excessively low voltage from the accel-
erator pedal position (APP) sensor 2 is sent
to ECM.
• An excessively high voltage from the accel-
erator pedal position (APP) sensor 2 is sent
to ECM.
• Harness or connectors
(APP sensor 2 circuit is open or
shorted.)
• APP sensor 2
