P011511 P011515	Engine coolant temperature sensor	The ECM estimates the engine coolant temperature to be 80°C (176°F).	Pass condition detected
P012011 P012015 P01201C P022011 P022015 P060444 P060604 P060629 P060647 P060A47 P060B49 P060D49 P060E49 P061E49 P065714 P06579E P160700 P210014 P210015 P211172 P211173 P211900 P211904 P211977 P21352B	Electronic throttle control system	The ECM cuts off throttle actuator current 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*3.	Pass condition detected and then ignition switch turned off
P019011 P019015 P123513	Fuel pressure sensor	The ECM performs fuel cut when the engine speed and engine load are high. Fuel pressure is set to 200 kPa.	Ignition switch off
P020113 P020213 P020313 P020413 P062D13	Injector driver (ECM)	The ECM performs fuel cut when the engine speed is 2000 rpm or higher.	Pass condition detected and then ignition switch turned off
P026A00	Intercooler system	Output is limited.	Pass condition detected
P030000 P030027 P030085 P030100 P030200 P030300 P030400 *4	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 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.	Pass condition detected and then ignition switch turned off
P052400	Oil pressure sender gauge assembly	Engine speed is limited due to fuel cut and throttle restriction (4000 rpm or less).	Pass condition detected
P056014	ECM +B circuit	Generator command is maintained.	Pass condition detected and then ignition switch turned off
P137800	Pre-ignition	Output is limited in low-speed boost region	Clear DTC after recovering to normal condition
P15EA12	Oil pressure switching valve assembly	Output is limited.	Pass condition detected
P212012 P212014 P21201C P21201F P212099 P212512 P212514 P21251F P21382B	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 ignition switch turned off
P222611 P222615	Atmospheric pressure sensor (Built into ECM)	Boost prohibited.	Ignition switch off
P223711 P223712 P223713 P223714 P223716 P223717 P22371B P22371A P225111 P225112	Air fuel ratio sensor (sensor 1)	Air fuel ratio feedback control is stopped	Pass condition detected and then ignition switch turned off

Tech Tips

*3: 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.
*4: Misfire-related fail-safe operations occur when catalyst overheat malfunctions occur.
