Fail-Safe Chart [08/2018 - 08/2019]

If any of the following DTCs are stored, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily or stops fuel injection.

DTC Code	Component	Fail-Safe Operation	Fail-Safe Deactivation Condition
P0011-00 P0011-07 P0015-00 P0021-00 P0021-07 P0025-00	VVT system	Idle up (control of combustion worsening). Stopping fuel-cut control.	Pass condition detected
P0030-12 P0030-13 P0050-12 P0050-13 P101A-9E P103A-9E	Air fuel ratio sensor heater	The ECM turns off the air fuel ratio sensor heater.	Engine switch off
P0036-12 P0036-14 P0056-12 P0056-14 P102A-9E P105A-9E	Heated oxygen sensor heater	The ECM turns off the heated oxygen sensor heater.	Engine switch off
P0087-00 P0088-00 P1235-13	Fuel pump assembly (for high pressure side)	The ECM performs fuel-cut when the engine speed and engine load are high. Fuel pressure is set to 200 kPa.	Engine switch off
P0100-12 P0100-14	Mass air flow meter sub-assembly	The ECM calculates fuel injection volume according to the engine speed and throttle valve position.	Pass condition detected
P0110-11 P0110-15	Intake air temperature sensor	The ECM estimates the intake air temperature to be 20°C (68°F).	Pass condition detected and then engine switch turned off
P0115-11 P0115-15	Engine coolant temperature sensor	The ECM estimates the engine coolant temperature to be 80°C (176°F).	Pass condition detected
P0120-11 P0120-15 P0120-1C P0220-11 P0220-15 P0604-44 P0606-04 P0606-29 P0606-47 P060A-47 P060B-49 P060D-49 P060E-49 P061E-49 P0657-14 P0657-9E P1607-00 P2100-14 P2100-15 P2111-72 P2111-73 P2119-00 P2119-04 P2119-77 P2135-2B	Electronic throttle control system	The ECM cuts off throttle actuator current and the throttle valve is returned to a 7° throttle position by the return spring. The ECM then adjusts the engine output by controlling fuel injection (intermittent fuel-cut) and ignition timing in accordance with the accelerator pedal angle to allow the vehicle to be driven at a low speed*1.	Pass condition detected and then engine switch turned off
P0190-11 P0190-15	Fuel pressure sensor (for high pressure)	The ECM performs fuel-cut when the engine speed and engine load are high. Fuel pressure is set to 200 kPa.	Pass condition detected and then engine switch turned off
P0201-13 P0202-13 P0203-13 P0204-13 P0205-13 P0206-13 P062D-13	ECM (injector driver)	The ECM performs fuel-cut when the engine speed is 2000 RPM or more.	Pass condition detected and then engine switch turned off
P0300-00 P0300-27 P0300-85 P0301-00 P0302-00 P0303-00 P0304-00 P0305-00 P0306-00 *2	Fuel injector assembly Electronic throttle control system	When a catalyst-damaging misfire occurs (MIL blinking), the following fail-safe operation is performed for catalyst overheat malfunction prevention. Under a low load and at a low engine speed: - Fuel cut is performed on the malfunctioning cylinder. Under a high load and at a high engine speed: - Throttle valve opening angle control is performed. - Fuel cut is performed on all cylinders or the malfunctioning cylinder.	Pass condition detected and then engine switch turned off
P0325-11 P0325-15 P0330-11 P0330-15	Knock control sensor	The ECM sets the ignition timing to maximum retard.	Engine switch off
P0351-13 P0352-13 P0353-13 P0354-13 P0355-13 P0356-13	Ignition coil assembly	The ECM cuts the fuel injection.	Pass condition detected
P0504-2B	Stop light switch assembly	The accelerator pedal opening angle is fixed when there is an accelerator pedal malfunction or history of a malfunction.	Pass condition detected and then engine switch turned off
P0560-14	ECM +B circuit	Generator command is maintained.	Pass condition detected and then engine switch turned off
P107A-11 P107A-15	Fuel pressure sensor (for low pressure side)	Fuel pump (for low pressure side) control is maintained. Output is limited.	Pass condition detected and then engine switch turned off
P21CF-13 P21D0-13 P21D1-13 P21D2-13 P21D3-13 P21D4-13	Fuel injector assembly (for port injection)	The ECM performs fuel-cut when the engine speed is 2000 RPM or more.	Pass condition detected and then engine switch turned off
P2120-12 P2120-14 P2120-1C P2120-1F P2120-99 P2125-12 P2125-14 P2125-1F P2138-2B	Accelerator pedal position sensor	The accelerator pedal position sensor has 2 sensor circuits: Main and Sub. If either circuit malfunctions, the ECM limits the engine output. If both circuits malfunction, the ECM regards the accelerator pedal as being released. As a result, the throttle valve is closed and the engine idles.	Pass condition detected and then engine switch turned off
P2237-11 P2237-12 P2237-13 P2237-16 P2237-17 P2237-1B P2240-11 P2240-12 P2240-13 P2240-16 P2240-17 P2240-1B P2251-11 P2251-12 P2254-11 P2254-12	Air fuel ratio sensor	Air fuel ratio feedback control is stopped	Pass condition detected and then engine switch turned off

HINT:

*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.
