DTC P2135

DTC P2135 Accelerator pedal position (APP) sensor No.1/No.2 voltage correlation
• The PCM monitors the input signals from accelerator pedal position sensor No.1 and accelerator pedal
position sensor No.2. If the difference between accelerator pedal position sensor No.1 and accelerator
pedal position sensor No.2 is more than 0.9 V, the PCM determines that there is a malfunction in the
accelerator pedal position sensor characteristic.
