Inspection Procedure

HINT:

Read freeze frame data using the hand-held tester or the OBD II. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, 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, and other data from the time the malfunction occurred.

1. Are there any other codes (besides DTC P2119) 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 the OBD II scan tool main switch ON.
   3. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.

   CHECK: 

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