Fail-Safe Operation

Even when a trouble has occurred in such areas of electronic fuel injection system that include the following parts and a failure signal is sent to ECM, control over the injector, ISC solenoid valve and other is maintained on the basis of the standard signals and/or back-up program prestored in the ECM while ignoring that failure signal and/or CPU. This function is called "FAIL-SAFE FUNCTION". Thus, with this function, a certain level of engine performance is available even when some failure occurs in such areas so that disability in running is avoided.

- Water temp. sensor
- Throttle position sensor
- Speed sensor
- Air flow sensor
