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.

  • 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
P0011, P0021 VVT system
  • Idling up (misfire prevention), or 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
P0012, P0022 VVT system
  • 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
P0015, P0025 Exhaust camshaft oil control valve
  • Idling up
  • Valve timing of bank that is operating normally is fixed at advanced angle
 Pass condition detected
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 800 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 opening 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 800 RPM or less
 Pass condition detected and then engine switch turned off
P0201, P0202, P0203, P0204, P0205, P0206, P0207, P0208, P062D, P062E Injector Driver (EDU)
  • Stop fuel injection for an abnormal cylinder and related other cylinders
  • Limit the engine speed to 1000 RPM or less
 Pass condition detected and then 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 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 800 RPM or less
 Pass condition detected
P1276, P1277, P1278, P1279, P127A, P127B, P127C, P127D Fuel injector for port injection
  • Limit the engine speed to 1000 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
  • Current the A/F sensor heater is cut
 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
(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.
