The fuel injectors in your Toyota are essential parts that work to deliver fuel to your engine at the precise time. They work by using electronically controlled valves that will open and close as needed to send gasoline to your engine. Your vehicle will typically have one injector per cylinder. You have an engine control unit, or ECU, that works to activate the injectors. This sends the fuel to the combustion chamber through the different nozzles. Fuel injectors are important components to maintain, because if you don't do so, they can start to develop wear and tear or might become clogged. It's important to know how to spot signs of a bad fuel injector so you can get a replacement sooner versus later. Fuel injectors might become clogged with debris or have mechanical issues that occur. Your check engine warning light can come on if you have a faulty fuel injector. While there are many reasons the light can come on, the ECU can trigger a warning light if your injectors aren't delivering the right amount of fuel. Your engine also might start to misfire because of a lack of fuel in the combustion chamber. Find OEM Toyota fuel injectors here on our site!
