TROUBLE DIAGNOSIS EC-81 C D E F G H I J K L M A EC Fail-safe Chart EBS00LVX When the DTC listed below is detected, the ECM enters fail-safe mode and the MIL lights up. DTC No. Detected items Engine operating condition in fail-safe mode P0102 Mass air flow sensor circuit Engine speed will not rise more than 2,400 rpm due to the fuel cut. P0117 Engine coolant tempera- Engine coolant temperature will be determined by ECM based on the time after turning Condition Engine coolant temperature decided (CONSULT-II display) Just as ignition switch is turned 40 ° C (104 ° F) More than approx. 4 minutes after 80 ° C (176 ° F) Except as shown above 40 - 80 ° C (104 - 176 ° F) (Depends on the time) When the fail-safe system for engine coolant temperature sensor is activated, the cooling P0122 Throttle position sensor The ECM controls the electric throttle control actuator in regulating the throttle opening in P1121 Electric throttle control (When electric throttle control actuator does not function properly due to the return spring (When throttle valve opening angle in fail-safe mode is not in specified range:) (When ECM detects the throttle valve is stuck open:) P1122 Electric throttle control ECM stops the electric throttle control actuator control, throttle valve is maintained at a P1124 Throttle control motor relay ECM stops the electric throttle control actuator control, throttle valve is maintained at a P1128 Throttle control motor ECM stops the electric throttle control actuator control, throttle valve is maintained at a P1229 Sensor power supply ECM stops the electric throttle control actuator control, throttle valve is maintained at a P2122 Accelerator pedal position The ECM controls the electric throttle control actuator in regulating the throttle opening in |
