A thermistor, whose resistance value varies according to the temperature, is built into each sensor. When the temperature is low, output from the sensors, the ECM determines the fuel injection time and the ignition timing to control the engine. DTC CODE DTC DETECTION CONDITION TROUBLE AREA P011B a. 7 hours or more have elapsed from engine stop on the previous trip. b. 15 seconds*1 or 102 seconds*2 after a cold engine start. c. The minimum Intake Air Temperature (IAT) after the engine starts is higher than -10°C (14°F). d. The average Engine Coolant Temperature (ECT) before the engine starts is higher than -10°C (14°F). e. f. IAT sensor ECT sensor ECM *1: for 100 L (26.4 US gal) Fuel Tank *2: for 144 L (38 US gal) Fuel Tank 3UR-FBE ENGINE CONTROL SYSTEM: SFI SYSTEM: P011B; Engi... |
