DTC COMPONENT FAIL-SAFE OPERATION FAIL-SAFE DEACTIVATION CONDITION engine speed: Throttle valve opening angle control is performed. Fuel cut is performed on all cylinders or the malfunctioning cylinder. P0327, P0328, P032C, P032D, P0332, P0333, P033C and P033D Knock Sensor ECM sets ignition timing to maximum retard. Ignition switch off P0351 to P0358 Ignition Coil ECM cuts fuel. Pass condition detected P0504 Stop Light Switch The accelerator pedal opening angle is fixed when there is an accelerator pedal malfunction detected P2120, P2121, P2122, P2123, P2125, P2127, P2128 and P2138 Accelerator Pedal Position (APP) 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 P2432, P2433, P2437 and P2438 Secondary Air Injection System Throttle valve opening angle control is performed Pass condition detected P2440 and P2442 Secondary Air Injection System Throttle valve opening angle control is performed Pass condition detected P2445 and P2447 Secondary Air Injection System Throttle valve opening angle control is performed Pass condition detected HINT: *1: The vehicle can be driven slowly when the accelerator pedal is depressed firmly and slowly.
