Finding the right Oxygen Sensor to change. 1997 Ford Taurus 3.0 engine?
I am an Electronics Technician (TV Repair) so I know how to use a Meter. I know the Ohms (around 6) for the Heater,I know what to check for the Voltage, but, Is the Voltage taken with the car running, or hot and not running ?
Any advice or tips to figure out which one?
Took it to Auto Zone and they said it was an Oxygen sensor problem.
I have the special socket.
First mistake is AUTOZONE!!!!! They can read codes all day long and sell sensors all day long and fix nothing. First off what O2 codes did you get? most likely P0171 P0174 P0172 P0173 ect. This does not not meen you have a bad sensor, it is a rich or lean code or possibly lack of switching. Of course a bad sensor can cause these codes, but generally they are caused by various other concerns such as vacuum leaks, leaking injectors, leaking fuel pressure regulators, contaminated MAF sensor ect… The only way to be certain of the cause is to monitor your BARO, STFTMS, LTFTMS, O211, O221, MAF ect… these PIDS help determine if you actually have a lean, or rich condition or maybe MAF concern. Then follow a diagnostic routine using real info, then make a proper repair. Before replcing a bunch of parts on a guess to do with a code from AUTOZONE I would have a reputable repair facility help you it will cost you less in the long run. Hope this helps
