A/f sensor circuit slow response (bank 1 sensor 1)
Hint: Sensor 1 refers to the sensor mounted in front of the three-way catalytic converter (twc) and located near the engine assembly. Description Refer to dtc p2195 (see page es-292). Monitor description After the engine is warmed up, the ecm performs air-fuel ratio feedback contro ...

Terminals of ecu (2006/01- )
Check air conditioning amplifier Measure the voltage and resistance of the connectors. Hint: Check from the rear of the connector while it is connected to the air conditioning amplifier. Hint: *: For 2gr-fe Using an oscilloscope, check waveform 1. Can communi ...

Starter relay circuit high
Description While the engine is being cranked, the positive battery voltage is applied to terminal sta of the ecm. If the ecm detects the starter control (sta) signal while the vehicle is being driven, it determines that there is a malfunction in the sta circuit. The ecm then illuminates ...
