Inspection Procedure

HINT: 

• The following conditions may also cause DTC P0505 to be set:
  1. The floor carpet overlapping slightly onto the accelerator pedal, causing the accelerator pedal to be slightly depressed and therefore the throttle valve position to be slightly open.
  2. The accelerator pedal being not fully released.
• Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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.
• Refer to "Data List / Active Test" [Engine Speed, ISC Feedback Value and ISC Learning Value]. Refer to DATA LIST / ACTIVE TEST .
