FAIL-SAFE CHART
If any of the following DTCs are set, the ECM enters fail-safe
mode to allow the vehicle to be driven temporarily.
NOTE:
*
: The vehicle can be driven slowly when the accelerator
pedal is depressed slowly. If the accelerator pedal is
depressed quickly, the vehicle may speed up and slow down
erratically.
DTCs
Components
Fail-Safe Operations
Fail-Safe Deactivation
Conditions
P0031, P0032, P0051 and P0052
Air-Fuel Ratio (A/F) Sensor
Heater
ECM turns off A/F sensor heater
Ignition switch off
P0037, P0038, P0057 and P0058
Heated Oxygen (HO2) Sensor
Heater
ECM turns off HO2 sensor heater
Ignition switch off
P0100, P0102 and P0103
Mass Air Flow (MAF) Meter
ECM calculates ignition timing
according to engine speed and
throttle valve position
Pass condition detected
P0110, P0112 and P0113
Intake Air Temperature (IAT)
Sensor
ECM estimates IAT to be 20
°
C
(68
°
F)
Pass condition detected
P0115, P0117 and P0118
Engine Coolant Temperature
(ECT) Sensor
ECM estimates ECT to be 80
°
C
(176
°
F)
Pass condition detected
P0120, P0121, P0122, P0123,
P0220, P0222, P0223, P0604,
P0606, P0607, P0657, P2102,
P2103, P2111, P2112, P2118,
P2119 and P2135
Electronic Throttle Control
System (ETCS)
ECM cuts off throttle actuator
current and throttle valve returned
to 6.5
°
throttle position by return
spring
ECM then adjusts engine output
by controlling fuel injection
(intermittent fuel-cut) and ignition
timing in accordance with
accelerator pedal opening angle,
to allow vehicle to continue at
minimal speed
*
Pass condition detected and then
ignition switch turned off
P0327, P0328, P0332 and P0333
Knock Sensor
ECM sets ignition timing to
maximum retard
Ignition switch off
P0351 to P0356
Igniter
ECM cuts fuel
Pass condition detected
P2120, P2121, P2122, P2123,
P2125, P2127, P2128 and P2138
Accelerator Pedal Position (APP)
Sensor
APP sensor has 2 sensor circuits:
Main and Sub
If either of circuits malfunctions,
ECM controls engine using the
other circuit
If both of circuits malfunction,
ECM regards accelerator pedal
as being released. As a result,
throttle valve is closed and engine
idles
Pass condition detected and then
ignition switch turned off
