FAIL-SAFE FUNCTION REFERENCE TABLE
When the main sensor malfunctions are detected by the diagnosis function, the vehicle is controlled
by means of the pre-set control logic to maintain safe conditions for driving.
Malfunctioning itemControl contents during malfunction
Air flow sensor1. Suspends lean burn operation.
2. Uses the throttle position sensor signal and engine speed signal (crank angle
sensor signal) to take reading of the basic injector drive time and basic ignition
timing from the pre-set mapping.
Intake air temperature sensorControls as if the intake air temperature is 25_
C.
Throttle position sensor (2nd
channel)1. Suspends lean burn operation.
2. Controls the throttle opening angle feedback (half as much as the opening
rate in the normal condition) by using signals from the throttle position sensor
(1st channel). However, this controlling system is not applied if the throttle
position sensor (1st channel) and throttle position sensor (2nd channel)
combination output voltage is outside 4 - 6 V.
3. Refrains from controlling the throttle opening angle feedback if the throttle
position sensor (1st channel) is also defective.
Engine coolant temperature
sensorControls as if the engine coolant temperature is 80_
C. (Moreover, the control system
is working until the ignition switch is turned OFF if the sensor signal returns to normal.)
Camshaft position sensorCuts the fuel supply once a malfunction is detected. (Only when there has been
no occasion of detecting No.1 cylinder top dead centre after the ignition switch
is turned ON.)
Vehicle speed sensor1. Suspends lean burn operation. However, the control is cancelled as a certain
time passes by with the engine speed of 1,500 r/min or more.
2. Suspends lean burn operation during the engine idling.
Barometric pressure sensorControls as if the barometric pressure is 101 kPa.
Detonation sensorFixes the ignition timing as that for standard petrol.
Injector1. Suspends lean burn operation.
2. Suspends the exhaust gas recirculation.
Ignition coil (incorporating pow-
er transistor)1. Suspends lean burn operation.
2. Cuts off the fuel supply to cylinders with an abnormal ignition signal.
Fuel pressure sensor1. Controls as if the fuel pressure is 5MPa.
2
. Suspends fuel injection. (when the low pressure is detected and the engine
speed is more than 3,000r/min)
Alternator FR terminalRefrains from controlling to suppress the alternator output to electrical load.
(Operated as a normal alternator)
Accelerator pedal position sen-
sor (2nd channel)1. Suspends lean burn operation.
2. Controls the throttle valve position by using signals from the accelerator pedal
position sensor (1st channel). (However, the control system is not applicable
if the difference from the accelerator pedal position sensor (1st channel) output
voltage is 1.0 V or higher.)
3
. Suspends the electronic controlled throttle valve system if accelerator pedal
position sensor (1st channel) is also defective.

DATA LIST REFERENCE TABLE
Caution
When shifting the select lever to D range, the brakes should be applied so that the vehicle does
not move forward.
NOTE
*1: Injector running time indicates the time where the power voltage is 11 V and the cranking speed
is 250 r/min or less. As the engine speed increases and the time passes by, the injector running
time decreases.
*2: There may be occasions of taking the injector running time approximately 10% longer than usual
when a vehicle has not been driven for a long time (mileage is no more than 500 km.)
*3: It is normal that the idle switch turns from ON to OFF when accelerator pedal position sensor (1st
channel) voltage increases by 200 - 600 mV from the idling position. Moreover, adjust the idle switch
and accelerator pedal position sesor if the idle switch keeps turning after the accelerator pedal is
depressed.
