its a really hard concept, just bring it into an auto shop.
An O2 sensor unscrews just like a spark plug.
You cannot repair an O2 sensor. Replace it.
Ain't no fixing an O2 sensor. If there is a problem with it, replace it with a new one.
most likely its one of your o2 sensor is bad not hard to replace but they can be kind of expensive
It unscrews just like a spark plug.
THE O2 SENSOR IS LOCATED ON THE MANIFOLD. IT JUST UNSCREWS OFF THE SIDE OF IT, THEN YOU JUST UNPLUG IT.
1996 was the switch over year from OBDI to OBDII so look for a second O2 sensor after the catalytic converter.
yes definately. replace the o2 sensor, and you might want to also replace your pcv valve
first of all the 3.8 is a v6 second the o2 sensors (2 of them) are in the down pipes just before the catalytic converters
did you mean code P0140 ? this means o2 sensor no activity( bank 1 sensor 2) in other words replace the O2 sensor. hope this answers your question.
Mazda 626 frm 1996 doesn't have O2 sensors, have you ECU/PCM inspected, it might have a minor damage.
You will see it if you look directly at the front of the motor. It will have a thick white wire and is screwed in the motor.
