Inspection Procedure

HINT:

• The detection of DTC P0505 may also be caused by: 1) the floor carpet overlapping onto the accelerator pedal, causing the accelerator pedal to be slightly depressed (throttle position to be slightly open); or 2) the accelerator pedal not being fully released.
• Read freeze frame data using the hand-held tester. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was LEAN or RICH, and other data from the time the malfunction occurred.

1. CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0505)
