11.13 Accelerator Pedal Position Sensor Failure

Failure codes: P2106, P2122, P2123, P2127, P2128, P2138

No. Operating steps Result Follow up steps

1 Put the ignition switch to “ON”. Next step

Yes Next step 2 Pull out accelerator pedal position sensor joint on

harness, and then use a multimeter to check if an

around 5V voltage signal is present between 3#,

6# pins of this joint and ground wire.

No Check the circuit

Yes Check the circuit 3 Pull out accelerator pedal position sensor joint on

harness, and then use a multimeter to check if it is

short or break circuit between 3#, 6# pins of this

joint and 32#, 33# pins of ECU.

No Next step

Yes Check the circuit 4 Pull out accelerator pedal position sensor joint on

harness, and then use a multimeter to check if it is

short or break circuit between 2#, 5# pins of this

joint and 36#, 35# pins of ECU.

No Next step

Yes Check the circuit 5 Pull out accelerator pedal position sensor joint on

harness, and then use a multimeter to check if it is

short or break circuit between 4#, 1# pins of this

joint and 16#, 40# pins of ECU.

No Next step

Yes Next step 6 Use a diagnostic tester to read signal output of

accelerator pedal position sensor, and then check

if signal 1 increases as opening of accelerator

pedal increases.

No Replace the sensor

assembly

Yes Check other part 7 Use a diagnostic tester to read signal output of

accelerator pedal position sensor, and then check

if signal 2 increases as opening of accelerator

pedal increases.

No Replace the sensor

assembly

Note: This pedal is an integrated circuit device, which can not be processed through repair; therefore,

during maintenance process, the service station can maintain it by means of part replacement and can not

disassemble the sensor.
