FAIL-SAFE FUNCTION REFERENCE TABLE
13100910190
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 item Control contents during malfunction
Air flow sensor 1. 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.
2. Fixes the ISC servo in the appointed position so idle control is not performed.
Intake air temperature
sensor Controls as if the intake air temperature is 25
_
C.
Throttle position
sensor (TPS) No increase in fuel injection amount during acceleration due to the throttle position sensor
signal.
Engine coolant
temperature sensor Controls as if the engine coolant temperature is 80
_
C.
Top dead centre
sensor Injects fuel to all cylinders simultaneously.
(However, after the ignition switch is turned to ON, the No. 1 cylinder top dead centre is not
detected at all.)
Barometric pressure
sensor Controls as if the barometric pressure is 101 kPa.
Oxygen sensor Air/fuel ratio feedback control (closed loop control) is not performed.
