Autozone has this Sensor (BOSCH) for around $115.00. They have a DENSO for much lmore around $269.00. Both of these are listed BEFORE the Catalytic Converter.

On Autozone site it says that I should get around 10 ohms between the +B and the HT on the currently installed A/F sensor when unplugged. I get less than 1 ohm. Searching for another site to see if that is the correct ohms. Another site said it was less.

Questions:

1. I bought an O2 Sensor removal tool, but the covers or plates that cover the area (Cat Converter?) on the front of the engine make it impossible for the tool to fit on the sensor. Should I take these covers off to work on the O2 Sensor or is there another tool that might be a deeper O2 socket?

2. Are one of these two replacements listed (hopefully the $115.00 version) the right A/F Sensor I need for the code?

3. Is there any other test that I can perform on the original sensor, prior to purchasing and installing this new $115 Sensor?

First option would dictate taking it to a dealer to fix. Second choice is take it to a really good and reliable mechanic to fix. After that you are a bit on your own as you know. Do what you need to do to remove the sensor and on the bench, check the resistance and compare to the new one. Take it to the parts store with your ohm meter and test both. If they are both close to each other then it might not be the problem.

What does your Service Manual say???

Bought the $115 A/F O2 Sensor from autozone. Got the loaner tool, with the deep O2 Socket. Too 15 seconds to unplug electrical socket for O2 Sensor. Took 45 Seconds to crack loose O2 Sensor with loaner socket, and unscrew. Too 30 seconds to put Antiseeze compound on threads. Took a minute to screw in and tighten new o2 Sensor, and plug in. Reset the codes another 2 minutes, and car CEL is OUT. Wife on her trip now.

From the reading I have done on the net, this job may have cost more than $500 at a dealer. Mine 43 dollars for OBII Reader. and 115 dollars for new Sensor.

Yes manual did help, but never did read between 1.8 and 3.x ohms on the two black wires. Not sure why my old O2 and New O2 sensor both read aroun 1.0, but this one works. Maybe my digital gauge is off for reading ohms, and something else is wrong with my old O2 sensor then the Heater circuit.

Thanks..
