Detecting Condition

If the ECM detects diagnostic trouble code "PO100" it operates the fail safe function, keeping the ignition timing and injection volume constant and making it possible to drive the vehicle.

HINT: After confirming DTC PO100 use the OBD II scan tool or LEXUS hand-held tester to confirm the mass air flow ratio from "CURRENT DATA".
