Inspection Procedure

HINT: 

• The following conditions may also cause DTC P0505 to be set:
  1. The floor carpet overlapping 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 help determine if the vehicle was moving or stationary, 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.
• Refer to "Data List / Active Test" [Engine Speed, ISC Feedback Value and ISC Learning Value]. Refer to DATA LIST / ACTIVE TEST [08/2012 - ] .
