Electronic throttle control system |
When a catalyst-damaging misfire occurs (MIL blinking), the following fail-safe operation is performed for catalyst overheat malfunction prevention.
1.
Under a low load and at a low engine speed: - Fuel cut is performed on the malfunctioning cylinder. 2.
Under a high load and at a high engine speed: - Throttle valve opening angle control is performed. - Fuel cut is performed on all cylinders or the malfunctioning cylinder. |
