This little guy basically measures the fuel pressure in your fuel rail—that’s the pipe that delivers fuel to the engine’s injectors. It sends that pressure reading as an electrical signal to your car’s computer – the Engine Control Unit or ECU. The ECU uses that information to figure out how much fuel to deliver to the engine. It’s a pretty simple job, really – measure the pressure and report back. Think of it as one of the many ‘eyes’ your car’s computer uses to make sure everything is running smoothly. The ECU needs to know if the fuel pump is delivering the correct pressure. If the pressure is too high or too low, it can affect how the engine runs, causing all sorts of problems. It works alongside other sensors, like the oxygen sensor, to help the car maintain the ideal air – fuel mixture. If this sensor goes bad, you’ll likely notice if you’re having trouble starting, or if the engine is running rough, hesitating when you accelerate, or even stalling. It can also cause your check engine light to come on, naturally. It isn’t something you can generally ignore for long. A bad reading throws off the whole fuel delivery system, which can lead to reduced fuel economy and even potentially damage other parts of your engine over time. We carry these pretty regularly, and you can often find a good one at places like Fixparts Online, but it’s something you want to address as soon as you suspect it’s failing. A failing sensor doesn’t necessarily mean a huge repair bill, but ignoring it could lead to bigger problems down the road.
