The ECM cuts off throttle actuator current for both bank 1, and the throttle valve is returned to a 8° 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 ignition switch turned off
P019011 P019015	Fuel pressure sensor (for high pressure)	Output power is limited. Fuel pressure is set to 200 kPa (2 kgf/cm2, 29 psi)	Ignition switch off
P020113 P020213 P020313 P062D13	ECM (injector driver)	Fuel cut is performed and then the output is limited when the engine speed is 1000 rpm or more.	Pass condition detected and then ignition switch turned off
P023400 P02351C	Turbocharger system	Boost prohibited.	Ignition switch off
P030000 P030027 P030085 P030100 P030200 P030300 *2	Port fuel injector assembly Direct 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 ignition switch turned off
P032511 P032515	Knock control sensor	The ECM sets the ignition timing to maximum retard.	Ignition switch off
P05042B	Stop light switch assembly	The accelerator pedal opening angle is fixed when there is an accelerator pedal malfunction or history of a malfunction.	Ignition switch off
P056014	ECM +B circuit	Generator command is maintained.	Pass condition detected and then ignition switch turned off
P107A11 P107A15	No. 2 fuel pressure sensor (for low pressure side)	Fuel pump (for low pressure side) control is maintained.	Ignition switch off
P137800	Pre-ignition	Output is limited in low-speed boost region.	Clear DTC after recovering to normal condition
P212012 P212014 P21201C P21201F P212099 P212512 P212514 P21251F P21382B	Accelerator pedal sensor assembly	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 ignition switch turned off
P21CF13 P21D013 P21D113	Port fuel injector assembly	The ECM performs fuel-cut when the engine speed is 2000 rpm or more.	Pass condition detected and then ignition switch turned off
P222611 P222615	Atmospheric pressure sensor (ECM)	Boost prohibited.	Ignition switch off
P223711 P223712 P223713 P223716 P223717 P22371B P225111 P225112	Air fuel ratio sensor (sensor 1)	Air fuel ratio sensor (sensor 1) air fuel ratio feedback control is stopped.	Pass condition detected and then ignition switch turned off
P22AB11 P22AB12 P22AB13 P22AB16 P22AB17 P22B211 P22B212	Air fuel ratio sensor (sensor 2)	Control based on air fuel ratio sensor (sensor 2) air fuel ratio feedback is stopped. The ECM turns off the air fuel ratio sensor (sensor 2) heater.	Pass condition detected and then ignition switch turned off
P23AA73	Air by-pass valve assembly	Output power is limited.	Pass condition detected and then ignition 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.

Freeze Frame Data

FREEZE FRAME DATA DESCRIPTION The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction...
