oxygen sensor ( in the exhaust , the sensors closest to the engine are used to
" sense " the amount of oxygen in the exhaust to send a signal to the PCM
so the air / fuel mixture for the engine is adjusted under various conditions )
where is the secondary 02 sensor on a 2004 crv
exaust leaks , faster if its before the 02 sensor
P0139 02 Sensor Circuit Slow Response (Bank 1 Sensor 2)P0139 02 Sensor Circuit Slow Response (Bank 1 Sensor 2)
02 sensor
underneath the cam rod with the 02 sensor
02 sensor heater curcuit malfunction (bank 1 sensor1)---change front 02 sensor if need be.
You have a bad 02 sensor after the catalytic converter.
That would be the sensor after the catalytic converter.
That would be the sensor in the exhaust after the catalytic converter ( downstream )
That is the sensor in the catalytic converter.
where is the 02 censor located
you do have an ( 02 ) sensor on the exhaust system
