Inspection Procedure

HINT:

• 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 (See FREEZE FRAME DATA ).
• This DTC relates to the Accelerator Pedal Position (APP) sensor.

1. READ VALUE USING TECHSTREAM (ACCEL POS #1 AND ACCEL POS #2)  (See INSPECTION PROCEDURE  )

   OK :  Go to step  3

2. CHECK HARNESS AND CONNECTOR (ACCELERATOR PEDAL POSITION SENSOR - ECM)  (See INSPECTION PROCEDURE  )

   OK : Go to next step 

3. REPLACE ACCELERATOR PEDAL ROD ASSEMBLY 

   Replace the accelerator pedal rod assembly (See REMOVAL ).

4. CHECK WHETHER DTC OUTPUT RECURS (ACCELERATOR PEDAL POSITION SENSOR DTCS) 
   1. Connect the Techstream to the DLC3.
   2. Turn the engine switch on (IG) and turn the Techstream on.
   3. Clear DTCs (See DTC CHECK/CLEAR ).
   4. Start the engine.
