So here's how to replace a front oxygen sensor for my 1999 C230 Kompressor.

Considering the fact that I've already changed my Mass Air Flow (MAF) sensor, what's left is the front oxygen sensor, which together with the MAF are used by the ECU to do closed-loop control of the air/fuel ratio.Īs for the rear (downstream) sensor, it only needs to be changed if it throws a code or the Check Engine Light turns on.

Increased fuel consumption, driveability problems (hesitation or surging), 'Check Engine Light' lit or emissions test failure could all be signs of an oxygen sensor in need of replacement.Īt 120K miles, I've already seen enough roughness and surges at low speeds to suggest incorrect air/fuel mixture.

Second generation heated oxygen sensors used on mid-1990s and newer vehicles are recommended to be changed every 100K miles.

If the converter gets hot enough, the catalyst substrate inside may actually melt forming a partial or complete blockage. A rich operating condition causes the converter to run hotter than normal.

An additional consequence of any oxygen sensor failure may be damage to the catalytic converter.

The voltage they produce is also not as large as they should be, giving the false impression that the fuel is leaner than it actually is, which causes higher gas consumption and higher emissions.

As oxygen sensors age, they become sluggish, so they are not quick enough to respond to changes in air/fuel mixture.

The oxygen sensor (previously called the 'lambda sensor') monitors the level of oxygen (O2) in the exhaust so that the ECU can regulate the air/fuel mixture to reduce emissions.Whether you like it or not, it is highly encouraged that you change upstream oxygen sensors every 100K miles.
