It is for the oxygen sensor. There are two, one before the catalytic convertor and one after, this is for the one after it. Follow the exhaust from the side of the engine down and look for something resembling a spark plug in the exhaust pipe.
Downstream ... This is after the Catalyst Converter.
DTC P0141 Indicates "O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)". Bank 1 Sensor 2 is the HO2S after the catalytic converter.On a 4 cylinder engine it is the sensor on or after cat. It could be a bad wire or a bad ecm most of the time it is the Sensor that goes bad. On a 6 cylinder engine with 4 oxygen sensors it is the bank with cylinder one, sensor after catalytic convertor.
P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
p0141 is for the sensor behind the catalytic converter.
