Inspection Procedure

HINT:

Read freeze frame data using a hand-held tester or OBD II scan tool. Freeze frame data record 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. Are there any other codes (besides DTC P2119) being output? 
   • YES: Go to DTC chart (See  DIAGNOSTIC TROUBLE CODE CHART   ). 
   • NO: Go to next step. 
2. Replace ECM and Clear DTC (Check if DTC output recur). 

   PREPARATION: 

   1. Replace the ECM.
   2. Clear DTCs (See PRE-CHECK  ).
   3. Start and warm up the engine.
   4. Run the engine at idle for 15 seconds or more.

   CHECK: 

   Read DTCs.

   OK: Standard: No DTC output 

   • OK: System is OK. 
   • NG: Replace throttle body (See  REMOVAL  ).
