INSPECTION PROCEDURE

HINT:  Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame records the engine conditions when
the malfunction is detected, when troubleshooting it is useful for determining whether the vehicle was running or stopped, the engine warmed up or
not, the air-fuel ratio lean or rich, etc. at the time of the malfunction.

System Too Lean (Fuel Trim) (CA Only.)
