Inspection Procedure

HINT:

Read freeze frame data using the hand-held tester. Freeze frame data records the engine condition when malfunctions are detected. 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.

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2111 OR P2112) 
   1. Connect the hand-held tester to the DLC3.
   2. Turn the ignition switch on (IG).
   3. Turn the tester on.
   4. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
   5. Read DTCs.

      Result: 

      DTC OUTPUT

      HINT:

      If any DTCs other than P2111 or P2112 are output, troubleshoot those DTCs first.

   1. B: GO TO DTC CHART (SEE  DIAGNOSTIC TROUBLE CODE CHART  ) 
   2. A: Go to Next Step. 
2. INSPECT THROTTLE W/MOTOR BODY ASSY (VISUALLY CHECK THROTTLE VALVE) 
   1. Check for contamination between the throttle valve and the housing. If necessary, clean the throttle body. And check that the throttle valve moves smoothly.

      OK: Throttle valve is not contaminated with foreign objects and moves smoothly. 

   1. NG: REPLACE THROTTLE W/MOTOR BODY ASSY (SEE  REPLACEMENT  ) 
   2. OK: Go to Next Step. 
3. CHECK WHETHER DTC OUTPUT RECURS (DTC P2111 OR P2112) 
   1. Connect the hand-held tester to the DLC3.
   2. Turn the ignition switch on (IG).
   3. Turn the tester on.
   4. Clear DTCs (see DTC CHECK/CLEAR  ).
   5. Start the engine, and fully depress and release the accelerator pedal quickly (to fully open and close the throttle valve).
   6. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
   7. Read DTCs.

      Result: 

      DTC OUTPUT
      
      

      Display (DTC Output)	Proceed To
      No DTC	A
      P2111 or P2112	B

   1. B: REPLACE ECM (SEE  REPLACEMENT  ) 
   2. A: CHECK FOR INTERMITTENT PROBLEMS (see  CHECK FOR INTERMITTENT PROBLEMS   )
