Does an oxygen sensor from a Mustang work properly in a Mercedes?

Yes, I understand that clean combustion should be the same in either car, but perhaps the sensor would be calibrated differently. That is, the signal the computer would expect.

To give a rough example, perhaps the Mustang computer expects a 5-volt signal from the O2 sensor, and the Mercedes expects 10-volts when burning clean. Use the wrong sensor, and your computer thinks something is wrong because the calibration is different.

I'm surprised it would even fit in your car. Are we talking about the sensor that normally threads into the exhaust pipe somewhere?
