Refer to
• Handle mass air flow sensor carefully to avoid damage.
• Do not clean mass air flow sensor with any type of detergent.
• Do not disassemble electric throttle control actuator.

crankshaft position sensor (POS).
• After performing each TROUBLE DIAGNOSIS, perform DTC
CONFIRMATION PROCEDURE or Component Function
Check. The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Component Function
Check should be a good result if the repair is completed.

the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
• Do not use ECM ground terminals when measuring input/out-

sistor. Use a ground other than ECM terminals, such as the
ground.
