Control
System
(ETCS)
When misfire occurs, fuel cut is performed
for catalyst overheat malfunction
prevention.
During normal load and normal
engine speed (MIL is blinking):
- Fuel cut is performed on
malfunctioning cylinder.
During high load and high
engine speed (MIL is blinking):
- Throttle valve opening angle
control is performed.
- All cylinder fuel cut or
malfunctioning cylinder fuel cut
is performed.

Knock Sensor
ECM sets ignition timing to maximum
retard.
Ignition switch off
P0351 to P0358
Igniter
ECM cuts fuel.
Pass condition
detected
P0401
EGR Valve
ECM assumes that EGR valve is closed so
that ignition advance is set to a safe
value.

P0403
EGR Valve
ECM assumes that EGR valve is closed so
that ignition advance is set to a safe
value.

Stop Light Switch
The accelerator pedal opening angle is
fixed when there is an accelerator pedal
detected
P2120, P2121, P2122,
P2123, P2125, P2127,
P2128 and P2138
Accelerator Pedal
Position (APP) Sensor
The accelerator pedal position sensor has
2 sensor circuits: Main and Sub.
If either circuit malfunctions, the ECM
limits the engine output.
If both circuits malfunction, the ECM
regards the accelerator pedal as being
released. As a result, the throttle valve is
closed and the engine idles.
Pass condition
detected and then
ignition switch
turned off
P2432, P2433, P2437
and P2438

HINT:
*1: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly. If the
accelerator pedal is depressed quickly, the vehicle may speed up and slow down erratically.
*2: Misfire related fail-safe operations occur when catalyst overheat malfunctions occur.
