ENGINE GENERAL INFORMATION AND DIAGNOSIS (M13 ENGINE) 6-2-19
Fail-Safe Table
When any of the following DTCs is detected, ECM enters fail-safe mode as long as malfunction continues to
exist but that mode is canceled when ECM detects normal condition after that.
DTC NO. DETECTED ITEM FAIL-SAFE OPERATION
P0102 Mass air flow circuit low input • ECM controls injector drive time (fuel injection vol-
ume) according to throttle valve opening (closed
throttle position or not).
• ECM stops EGR control.
P0103 Mass air flow circuit high input
P0112 Intake air temperature sensor circuit
low
• ECM controls actuators assuming that intake air
temperature is 20°C (68°F).
P0113 Intake air temperature sensor circuit
high
P0117 Engine coolant temperature circuit low • ECM controls actuators assuming that engine cool-
ant temperature is 80°C (176°F).
• ECM operates radiator fan.
P0118 Engine coolant temperature circuit
high
P0122 Throttle position circuit low input • ECM controls actuators assuming that throttle open-
ing is about 20 deg.
P0123 Throttle position circuit high input
P0335 Crankshaft position sensor circuit • Fix ignition timing.
• ECM changes injection control system from
sequential injection to simultaneous one.
P0340 Camshaft position sensor circuit ECM changes injection control system from sequential
injection to simultaneous one.
P0500 Vehicle speed sensor ECM controls actuators assuming vehicle speed is 0
km/h (0 mile/h).
P2227 Barometric pressure sensor perfor-
mance problem
ECM controls actuators assuming that barometric
pressure is 101.33 kPa (762 mmHg).
