Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 3UR-FE ENGINE CONTROL
SFI SYSTEM - FAIL-SAFE CHART
If any of the following DTCs are stored, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily.
| DTC | Component | Fail-Safe Operation | Fail-Safe Deactivation Condition |
| P0011, P0021, P0015 and P0025*2 | Camshaft oil control valve (OCV) | Idle up (control of combustion worsening) Stopping fuel cut control | Pass condition detected |
| P0031, P0032, P0051, P0052 and P102D and P105D | Air Fuel ratio (A/F) Sensor Heater | The ECM turns off the A/F sensor heater. | Engine switch off |
| P0037, P0038, P0057, P0058, P101D and P103D | Heated Oxygen (HO2) Sensor Heater | The ECM turns off the HO2 sensor heater. | Engine switch off |
| P0102 and P0103 | Mass Air Flow (MAF) Meter | The ECM calculates ignition timing according to the engine speed and throttle valve position. | Pass condition detected |
| P0112 and P0113 | Intake Air Temperature (IAT) Sensor | The ECM estimates the IAT to be 20°C (68°F). | Pass condition detected |
| P0115, P0117 and P0118 | Engine Coolant Temperature (ECT) Sensor | The ECM estimates the ECT to be 80°C (176°F). | Pass condition detected |
| P0120, P0121, P0122, P0123, P0220, P0222, P0223, P0604, P0606, P060A, P060B, P060D, P060E, P0657, P2102, P2103, P2111, P2112, P2118, P2119 and P2135 | Electronic Throttle Control System (ETCS) | 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 opening angle to allow the vehicle to continue at minimal speed*1. | Pass condition detected and then engine switch turned off |
| P0327, P0328, P032C, P032D, P0332, P0333, P033C and P033D | Knock Sensor | The ECM sets the ignition timing to maximum retard. | Engine switch off |
| P0351 to P0358 | Ignition Coil | The ECM cuts fuel. | Pass condition detected |
| P0504 | Stop Light Switch | The accelerator pedal opening angle is fixed when there is a accelerator pedal malfunction or history of a malfunction. | Pass condition detected and then engine switch turned off |
| P2120, P2121, P2122, P2123, P2125, P2127, P2128 and P2138 | Accelerator Pedal Position (APP) Sensor | The APP 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 |
- 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: Only for M-OBD.
