Fuel Sensors, Relays & Switches

The fuel injection system gives you the kind of efficiency and performance older technologies are not capable of, but it comes at a cost. This cost is complexity, and there are more things waiting to go wrong with your fuel injection system than with older engines, so you need to keep on top of your maintenance. An important part of the system is a number of different sensors used to determine how much fuel and oxygen is to be mixed into the cylinder.

Featured Products

The range of sensors feeding information to your vehicle's computer is important, because it is this information that determines how much fuel and air are mixed together to be burnt in the cylinder. When the sensors are working well, your vehicle runs efficiently and gives you the power you expect. However, when one or more of the sensors fail, your vehicle's computer gets the wrong information, and efficiency and performance become less and less.

We aim to provide our customers with the finest Fuel Sensors, Relays & Switches the industry can offer, which is why we accept no compromise when it comes to the quality. Created by the most reputable names in the industry, such as Delphi, Dorman, Airtex, Motorcraft, Genuine, Forecast, Bosch the Fuel Sensors, Relays & Switches we've gathered for you feature precise design and everlasting durability.

To check your sensors, you need to know what they look like. Unfortunately, they can be difficult to find because they are almost always small, and will usually be deeply embedded into the component they are measuring. However, there are some things you can do to lift your chances of finding them, and one of those is consulting the vehicle's hand book. Each sensor will usually have an electrical cable running from it to the vehicle's computer, and most sensors are small. Of course, finding these sensors can be difficult but very worthwhiles because you will eventually need to replace them.

Because they work every time you start the engine, they will wear out after a period of time. They will usually last longer than most components in the vehicle, but they can fail without warning because they are close to the hot engine. A number of them, including the coolant temperature sensor, will also have liquids and other substances running through or around them, and any contaminants in those substances can cause an early fail. When one or more sensors do fail, you will quickly become aware of it because the symptoms are serious.

The symptoms of failing sensors include things like your engine running roughly at idle or under power, a fast idle when the engine is warm because the coolant temperature sensor has failed, or even an inability to start because the oxygen sensor is providing the wrong information so the wrong mixture of fuel and air is being used. Each symptom can begin slowly, so you barely notice it, but they can quickly become worse over a short period of time, and you can find your vehicle impossible to drive. Once these symptoms appear, it is time to replace the right sensor!

The throttle controller will basically bypass the computer in the vehicle. It is designed to take the information right from the accelerator position sensor and compile it in a high speed controller circuit that compiles the signal sent from the Accelerator position sensors. With this controller you are able to program it to different options and the throttle...

1985 Chevy Cavalier | Posted by Thomas | (Woodstock, GA)

I was rebuilding the Fuel system in a 85 Chevy Cavalier and a friend told me I should check out this place he found on the internet, CARiD so I purchased everything that I needed it came in a timely fashion, a few days it was of good quality the fuel pump could of had a few more details in the instructions of installation, the relay was fine, the fuel injector was very good all the gaskets came with it, so all in all in am satisfied with my purchase. The wife's car is running like new again, no complaints. I am looking for some 13" wheels and tires for the same vehicle if you carry them e-mail me and let me know, your web-site says it takes a 14" but it came with 13's I bought the car new don't think 14's will fit, so let me know. Thanks for the help.
