Inspection Procedure

HINT:

• When the throttle position is slightly opened (the accelerator pedal is slightly depressed) because a floor carpet is overlapped on the accelerator pedal, or if not fully releasing the accelerator pedal, etc., DTC P0505 will possibly be detected.
• Read freeze frame data using the hand-held tester or the OBD II scan tool. 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, as well as other data from the time when a malfunction occurred.

1. Are there any other codes (besides P0505) being output? 

   PREPARATION: 

   1. Connect the hand-held tester or the OBD II scan tool to the DLC3.
   2. Turn the ignition switch ON and push the hand-held tester or OBD II scan tool main switch ON.
   3. When using hand-held tester, enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO/CURRENT CODES.

   CHECK: 

   Read the DTC using the hand-held tester or the OBD II scan tool.
