Warning Signs that Your Porsche’s Oxygen Sensor is Bad

Porsche’s are powerful but intricate vehicles with a reputation of power, luxury, and style. One of its many components is the oxygen sensor. A Porsche’s oxygen sensor keeps track of your vehicle’s air to gasoline ratio and uses a computer to modify it, if necessary.

Several factors can affect the amount of oxygen in your Porsche’s engine, which can make it run rich or lean. Your Porsche’s oxygen sensor has everything to do with this dynamic. Let’s take a look at what you can do if your Porsche’s oxygen sensor is bad and how you can tell.

Your Check Engine Light Comes On

When your Porsche’s check engine light comes on, it almost always means trouble. Porsche’s are advanced vehicles that can self-correct to some extent, so when a problem is deemed too much for your Porsche to fix the check engine light will illuminate. This can be initiated by a bad oxygen sensor, but a bad gas cap or loose gas cap fit can set it off.

Declining Gas Mileage

Your Porsche’s gas mileage will vary based on the type of travel you are doing. Driving on the highway almost always yields better fuel economy than driving in the city. If you start to notice the fuel economy of your Porsche declining substantially, your oxygen sensor may be to blame.

When the oxygen is too rich or lean, your fuel economy suffers. A gradual decrease in fuel economy is common, but eventually, you will notice the vast difference.

An Engine That Sounds Noisy And Rough

The way a vehicle’s engine sounds normally can be difficult to explain, but it should sound smooth and even with easy transitions when shifting. If your Porsche’s oxygen sensor is bad, it may cause your engine to run irregularly or stall altogether. Your engine’s timing or combustion intervals may be off, so other functional problems may occur. Stalling or slower acceleration is also common with a bad oxygen sensor, which can be very dangerous as you’re merging into traffic.

Failing An Emissions Test

Many emissions tests fail, due to undetected bad oxygen sensors. It can cost hundreds to fix the problem and pass your emissions test, which is necessary for a vehicle inspection in some states. A bad oxygen sensor can also cause a horrible smell in your Porsche, and it could cause carbon monoxide to come back into the cabin.

Age Of Your Porsche

Older Porsche models are more prone to corrosion, wear, and tear, and byproduct buildup, due to their age and use. This can cause your vehicle’s oxygen sensor to go bad more quickly, so it is important to keep an eye on this component in older models. Replacing your oxygen sensor in older Porsche models should also be done more frequently than in newer Porsches.
