Pontiac Oxygen Sensor

Passing emissions inspections with flying colors is way easy. You just have to make sure that your emission system is properly functioning and your Pontiac oxygen sensor is in good condition. Having a Pontiac oxygen sensor that’s on tiptop condition doesn’t only improve vehicle emissions but also save you money for fuel costs and repair bills. That’s how important your Pontiac oxygen sensor is. If properly maintained, it enhances the automobile’s fuel efficiency, reduces exhaust emissions and minimizes the risk of costly damage to the vehicle’s catalytic converter. Aside from that, Pontiac oxygen sensors that are in good operating condition also gives top engine performance.

Oxygen sensor is present in all vehicles produced after 1980. Oxygen sensor is spark plug shaped mechanism aimed to perform a very critical task in your automobile even in the harshest of environments. A very vital component of the vehicle’s emissions control system, the oxygen sensor measures the oxygen content of the exhaust after it passing through the catalytic converter. It is an electronic equipment that supplies data to the engine management computer after it has precisely checked the exhaust hundreds of times per minute. Generally, the function of the oxygen sensor is to help the engine achieve a competent performance and ensure that the vehicle will release safer and less hazardous emissions.

On modern vehicles, oxygen sensors are usually located in the engine’s exhaust manifold to sense whether the mixture of gasoline and air going to the engine is lean or rich and converts its status into a corresponding voltage signal. This voltage signal will be sent to the engine management (ECU) computer, which in turn gives a command to the mixture control solenoid positioned in the carburetor to regulate the mixture before it enters the engine. Through this process, your vehicle’s engine will be given not just low exhaust emissions but also the best possible fuel economy.

If your Pontiac oxygen sensor becomes defective, the computer of your vehicle isn’t anymore capable of determining the accurate air and fuel ratio. It thus ends up guessing, which causes the car to perform poorly. It will also require more fuel than it needs before. When this happens, you really need to look for replacement Pontiac oxygen sensor. There are lots of auto-part store in the industry that offers replacement Pontiac oxygen sensor. They are excellently made to perform the task of your factory installed Pontiac oxygen sensor. For that reason, your replacement Pontiac oxygen sensor needs to be capable enough so that the engine performance, gas mileage and vehicle emissions will not be compromised.
