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.

P0016, P0017, P0018, P0019	Valve timing deviation	Power to camshaft timing control motor is cut Valve timing of bank that is operating normally is fixed at maximum retard angle	Pass condition detected and then engine switch turned off
P0031, P0032, P0051, P0052	Air-Fuel Ratio (A/F) Sensor Heater	ECM turns off A/F sensor heater	Engine switch off
P0037, P0038, P0057, P0058	Heated Oxygen Sensor (HO2S) heater	ECM turns off HO2 sensor heater	Engine switch off
P0087, P0088	Fuel pump for high pressure	Stop the fuel pump for high pressure Limit the engine speed to 2000 rpm or less	Pass condition detected
P0102, P0103, P010C, P010D	Mass Air Flow (MAF) meter	ECM calculates ignition timing according to engine speed and throttle valve position	Pass condition detected
P0097, P0098, P0112, P0113	Intake Air Temperature (IAT) sensor	ECM estimates IAT to be 20°C (68°F)	Pass condition detected
P0115, P0117, 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, P2135	Electronic Throttle Control System (ETCS)	ECM cuts off throttle actuator current and throttle valve returns to 7° 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 angle to allow vehicle to continue at minimal speed*1.	Pass condition detected and then engine switch turned off
P0190, P0192, P0193	Fuel pressure sensor	Stop the fuel pump for high pressure Limit the engine speed to 2000 rpm or less	Pass condition detected and then engine switch turned off
P0201, P0202, P0203, P0204, P0205, P0206, P0207, P0208	Injector driver (EDU)	Stop fuel injection for an abnormal cylinder and related other cylinders Limit the engine speed to 3000 rpm or less	Engine switch turned off
P062D, P062E	Injector driver (EDU)	Shut off the INJ (INJ2) relay	Engine switch turned off
P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 and P0308*2	Electronic throttle control system	During high load and high engine speed (MIL is blinking) - Throttle valve opening angle control is performed	Engine switch turned off
P0327, P0328, P0332, P0333 P032C, P032D, P033C, P033D	Knock sensor	ECM sets ignition timing to maximum retard.	Engine switch off
P0351 to P0358	Ignition coil	ECM cuts fuel	Pass condition detected
P0504	Stop light switch	Accelerator pedal angle is fixed	Pass condition detected
P1235, P1236	Fuel pump for high pressure side (spill control valve)	Stop the fuel pump for high pressure Limit the engine speed to 2000 rpm or less	Pass condition detected
P1276, P1277, P1278, P1279, P127A, P127B, P127C, P127D	Fuel injector for port injection	Limit the engine speed to 2000 rpm or less Fuel cut of malfunction cylinder	Pass condition detected and then engine switch turned off
P2237, P2238, P2239, P2240, P2241, P2242, P2252, P2253, P2255, P2256	A/F sensor	Air-fuel ratio feedback control is stopped	Pass condition detected and then engine switch turned off
P2120, P2121, P2122, P2123, P2125, P2127, P2128, P2138	Accelerator Pedal Position (APP) sensor	APP sensor has 2 sensor circuits: Main and Sub. If either of the circuits malfunctions, ECM controls engine using the other circuit. If both of the circuits malfunction, ECM regards accelerator pedal as being released. As a result, throttle valve is closed and engine idles.	Pass condition detected and then engine switch turned off

NOTE:

*1: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly. If the accelerator pedal is depressed quickly, the vehicle may speed up and slow down erratically.

*2: Misfire related fail-safe operations occur when catalyst overheat malfunctions occur.
