| Trouble item | Controls to be provided in the event of trouble |
|---|---|
| Air flow sensor | timing (1) Injector basic drive timing ad basic ignition read from the preset map based on the throttle position sensor (TPS) signal ad engine speed signal (crank agle sensor signal): (2) Idle speed controi servo fixed at predetermined position, and no idling speed control achieved |
| Intake air tem- perature sensor | Controls provided on the assumption that intake air temperature is 259€ (77'F) |
| Throttle position sensor (TPS) | No additional fuel injection provided on the basis of throttle position sensor signal at acceleration |
| Engine coolant temperature sensor | Controls provided on the assumption that engine coolant temperature is 80*C (1762F) (Even if the sensor signal returns to normal, this control mode is retained until the ignition switch is set to OFF , |
| Cam position sensor | (1) Fuel injected into all cylinders simultaneously cylinder top dead center has been detected since the ignition switch (Provided that no No. was placed in the ON position) (2) Fuel cut 4 seconds after a failure was detected cylinder top dead center has been detected since the ignition switch (Provided that no No_ was placed in the ON position) |
| Barometric pressure sensor | Controls provided on the assumption that barometric pressure is 101 kPa (758 mm Hg, 29.8 in. Hg)l |
| Detonation sensor <DOHC> | timingfor super petrol to the timing for standard petrol. The ignition timing is switched from the |
| Ignition coil and power transistor unit | Fuel cut for cylinders whose ignition signal is abnormal |
| Oxygen sensor | No air-fuel ratio feedback control (closed loop control) achieved |
