Any idea how much an oxygen sensor costs to replace?

I didn't say it was good for your car, but if you can do some basic math you can 'fix' your engine to expect the voltage drop across an O2 sensor in 'ideal' conditions. Performance will take a bit, and it's probably illegal, but it beats having the engine running in the 'default' mode when the voltage across the sensor is out of range (which is why it needs to be replaced).

Any ideas?

Its for a 95 BMW 325i w/102K miles.

shoot your mechanic. even on a bmw, the sensor should be not much more than 100$ (my non-bmw sensor was 60$)

labor took me 5 minutes.. and i had never done it before. old one was on there tight so i knocked it loose with a flathead & hammer... put the new one on and connected the wires.. badabing

You might as well leave the thing unplugged.

The air/fuel requirements of an engine change across it's RPM range, engine load, and temperature conditions. The O2 sensor tells the ECM to change the injector pulsewidth to maintain a proper 14:1 air fuel ratio depending on those conditions.

Putting a resistor in there would probably provide a proper reading under one specific condition. The other 99% of the time it would be incorrect. It will never run right.

Resistors don't change their resistance values.

So add another 150-175 in labor, and you have your quote.
It also depends on how hard it is to get to in your car, never worked on a bimmer.

I wouldn't put those in any car. Buy the genuine BMW parts, they come with the correct wiring harness which to me is well worth the extra cost.

It is an easy do it yourself job if the sensors aren't too difficult to get to. Using an open end wrench just unscrew the old one and disconnect the wiring harness and screw in the new one.

LOL! BMW almost certainly installs Bosch as OEM.

I can't do it myself even if I knew how. The forms have to be filled out by an authorized service center before the state will pass my car again.

Bosch makes most OEM O2's....

The stock O2's out of my Stang were Bosch...my buddy just got a '00 528i, and it's got two Bosch's in it.

If anything, you might be describing universal O2's, which aren't usually just plug in.

It's not like O2's are some super complicated piece if equipment...

When you buy one for your car @ Autozone, it plugs in and is the exact same as the factory piece...

Yes but they don't come with the correct wiring harness which is the only reason I suggested he buy the OEM version. Duh...:roll:

$4 for an O2 sensor at the junkyard.
Rent the tool for $0 from autozone.
Total cost: $4.

The mechanic says it will cost $77.50 to get it to pass emissions.

Fine by me.
