INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand−held tester or the OBD II scan tool. Freeze frame data records the

mine if the vehicle was running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean
or rich, as well as other data from the time when a malfunction occurred.
1 Check valve timing (Check for loose and jumped tooth of timing chain)
(See page EM−16).
OK
Replace ECM (See page SF−78).
