13E-24
P0093: CRS (Fuel Leak) (warning lamp flashes: 22)
P0101: Airflow Sensor (Plausibility) (warning lamp flashes: 17)
P0102: Airflow Sensor (Low) (warning lamp flashes: 17)
P0103: Airflow Sensor (High) (warning lamp flashes: 17)
Generation condition Fuel system is leaking (significant leakage).
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit Engine stops.
Possible causes
• Malfunction of supply pump
• Malfunction of pressure limiter
• Airtight malfunction of injector
• Clogging of fuel system
Generation condition
Engine electronic control unit has judged air flow sensor abnormal as a result of
comparison with conditions of other sensors.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit
• Carries out control using a backup value (airflow rate equivalent to rate for low
idle speed operation).
• Injection quantity is limited.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped
Possible causes
• Open-circuit or short-circuit of harness between engine electronic control unit
and Air flow sensor
• Malfunction of each connector
• Malfunction of air flow sensor
• Malfunction of engine electronic control unit
Generation condition Airflow sensor voltage is lower than specified value.
