Inspection Procedure

HINT:

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, and other data from the time the malfunction occurred.

1. Is there DTC P2111 or P2112 being output. 
   1. NG: Go to relevant DTC chart (see  DIAGNOSTIC TROUBLE CODE CHART  ).
