to exist but that mode is canceled when ECM detects normal condition after that.
DTC NO. TROUBLE AREA FAIL SAFE OPERATION
P0100
(No.33, 34)
MAF SENSOR
• Injector drive time (fuel injection volume) is determined accord-
ing to throttle valve opening and engine speed.
• EGR valve stops.
• Air flow of IAC valve is limited.
