DTC P2135: Throttle / Pedal Position Sensor / Switch “A”/“B” (Main / Sub) Voltage CorrelationS7RS0B1104076
Wiring Diagram9
Ground circuit check
1) Remove ECM from its br acket with ECM connectors
connected.
2) Check for proper connection of ECM connector at “E23- 51” terminal.
3) If OK, measure resistance between “E23-51” terminal of ECM connector and engine ground.
Is resistance below 5
Ω? “WHT” wire is open or
high resistance circuit.
Faulty ECM ground
circuit. If circuit is OK,
substitute a known-
good ECM and recheck.
10 APP sensor check
1) Check APP sensor (sub) re ferring to “APP Sensor
Assembly Inspection in Section 1C”.
Is output voltage within specified value? Substitute a known-
good ECM and recheck.
Replace APP sensor.
