Accelerator Pedal Position Sensor Failure - Chery QQ6 Service Manual

11.13 Accelerator Pedal Position Sensor Failure

Failure codes: P2106, P2122, P2123, P2127, P2128, P2138
No.
Put the ignition switch to "ON".

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.
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.
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.
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.
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.
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.
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.
