You are already paying inflated prices for the fuel you’re pumping into your gas tank, so why would you want to deflate your wallet by letting your engine waste gas? If you have a faulty Chrysler PT Cruiser oxygen sensor, that is exactly what your engine is doing. Your engine generates power by burning a mixture of oxygen and fuel in your combustion chambers. The job of your PT Cruiser oxygen sensor, which is located near your exhaust manifold, is to tell your vehicle’s onboard computer how much fuel to inject into the cylinders, according to the amount of oxygen the sensor is reporting.

The optimal oxygen-to-fuel ratio is 14.7 to 1, and that is the number your Chrysler PT Cruiser oxygen sensor strives for. However, if there is a problem with this sensor, your vehicle’s computer is not receiving accurate oxygen measurements, because the oxygen sensor is the only one located in the direct path of your exhaust.

When your engine has to guess at oxygen content, it will inject too much fuel rather than too little, because too little fuel can damage your engine. Your fuel will not be used to optimal efficiency. In addition, a bad Chrysler PT Cruiser oxygen sensor will eventually cost you even more money, since the excess fuel running through your exhaust system will damage your catalytic converter. Often, a faulty oxygen sensor will work intermittently rather than stop working altogether, so it can be difficult to tell when there is a problem. Poor gas mileage, rough engine running, and black or foul-smelling exhaust smoke can indicate a bad PT Cruiser oxygen sensor, but these symptoms can also stem from other problems. You should replace your oxygen sensor at least every 100,000 miles, and whenever you have other exhaust work done.Find the oxygen sensor you need right here in our extensive online catalogue.
