Mercury Grand Marquis Replacement Oxygen Sensor Information


The Mercury Grand Marquis oxygen sensor monitors the amount of burned gases in the exhaust system. Depending on the year and model of your Mercury Grand Marquis, the oxygen sensor is usually located on the header pipe. It tells whether the fuel mixture in your engine contains too much fuel (rich) or too much air/oxygen (lean). The electronic fuel injector sensor will then tell your vehicle to adjust the mixture according to the conditions which change according to variables such as altitude and ambient temperature of the environment. As the vehicle travels higher in altitude, there is less oxygen available and will need to provide less fuel and needs to compensate one way or another. If the CO2 sensor malfunctions, it can dump fuel and begin smoking black smoke from the tailpipe indicating that there may be too much fuel and not enough air. Removing the oxygen sensor is done simply and quickly. Generally it is visible on the exhaust header and can be easily removed with an open-end or box wrench. Unplug the old CO2 sensor first. This is important because the wire twists along with it and could twist right out of the sensor, then just screw in the new one and plug in the wire.

Research on Oxygen Sensor for Mercury Grand Marquis

Mercury Grand Marquis Bumper Cover

Reliable and powerful, your Mercury Grand Marquis represents a rare combination in the automotive industry, and that’s why it has been such a popular vehicle through so many design generations. When your bumper has been visually damaged, a new bumper cover can often provide the cosmetic repair you need without a full replacement. That’s because the Mercury Grand Marquis bumper cover was built to take the initial hit without letting your bumper be permanently damaged, making it more likely that you can just replace the cover itself.

Parts Geek recognizes that a new bumper cover is an opportunity to change up your vehicle’s visual styling, which is why we stock as wide a variety as possible for our customers. When you can choose between practically any bumper cover manufacturer that services your vehicle, finding just the right look gets to be a lot easier.

What is the Bumper Cover?

Bumper covers are a rubber or composite sheath that goes over the metal bumper. They absorb the first impact, which reduces damage to both vehicles, and they are also built to take damage easily on the theory that a cover is going to be easier and more cost effective to replace than a full bumper.

How Much Does a New Mercury Grand Marquis Bumper Cover Cost?

There are a few factors that control the cost of a new bumper cover:

  • The materials used in the manufacture
  • The stylistic elements that go in to the bumper cover’s visual appeal
  • The brand of manufacturer

Depending on the choice you make, your new bumper cover could cost as little as $75 or as much as $225.

When Should I Replace a Bumper Cover?

These parts are made to last until they actually sustain damage, so the best time to replace them is after an accident. Otherwise, they should not wear out on you the way that some mechanical system components do. Of course, if the weather and wear winds up taking a toll on the bumper cover’s appearance, you may want to take the time to order a replacement early.
