Hi, I could do with some help in getting to whatever is bringing on the engine exhaust warning lamp. Checked code and found P0141 O2 sensor heater circuit malfunction (bank1 sensor 2). I believe this is the after cat lamda sensor. Check resistance of heater in sensor and got 9 ohms. Checked supply voltage to heater and got 0 volts. Fuse details in handbook do not give details of this fuse. Does anyone know which fuse supplies the sensor heater? Car is an April 05 model. Thanks.
