Cheapskate question

After they got the new engine in my Jeep the check engine light came on.
Not really a big surprise, it's been doing that once in a while for
about the last 100,000 miles.

The put it on the scanner and it was the rear oxygen sensor, which costs
about $140.

My understanding is that sensor basically just tells the computer the
Cat is working, and it doesn't really effect the way the engine runs.

Now the cheapskate question. These sensors go bad because they have
deposits built up on them correct? Has anyone had any luck cleaning one
of these things? If I have to spend the money I'll spend the money...
after spending about 4 grand on an engine $140 isn't that much, but it's
STILL $140 bucks!

Thanks!

Sensors can't be cleaned. Chemical sprays kill them (RTV especially).
I have heard folks burn them clean with a acetylene torch. At any rate,
$140 is too much, chryslerpartsdirect.com has them for about $84 and
NAPA has them for $76 (BSH 13138)

Replaceing the sensor is a one-bannanna job. Take the old one out,
screw the new one in, and hook it up.

The cheapest place on those sensors that I have seen is at
www.xtremeterrain.com

They have them for like $55.00!

Wow, that is cheap! Have you or anyone else here done business with
them? Any idea if this a quality part or am I going to be replacing it
in a year?

Thanks!
