Question about 1999 Mazda 626
Fault code P0133 O2 Sensor circuit slow response (Bank 1 Sensor 1) 1999 Mazda 626 24 valve V6 How do I look up the part # and how can I replace it. I know how to use my tools, just not where the o2 sensor is and how to change it. Thanks.
This code does not always mean the O2 sensor is low, but if u want to replace it here is the info to do that and the part number.
The sensor you want is the one in the exhaust pipe of the engine cylinder bank that has #1 cylinder in it, as you face the engine with the hood open the cylinder bank u want is the rear bank, u will need to jack the car up and get under it to remove the sensor, u may also need a special socket to remove it, the sensor is the one that is before the catalytic converter. part number is:DENSO Part # 2344068
REAR; Before Catalyst
