Inspection Procedure

HINT

When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction
• This DTC relates to the accelerator pedal position sensor
