This little guy basically measures the amount of oxygen left in your exhaust gases after combustion. It doesn’t just give a simple “yes” or “no” though, it gives a voltage reading. A higher voltage usually means there’s more oxygen, a lower voltage means less. Modern engines use these readings constantly. There are usually several of these sensors – one upstream of the catalytic converter, and one or more downstream. It's a critical part of your engine’s computer system, the ECU. The ECU uses the signal from this sensor to fine – tune the air – fuel mixture going into your engine. It’s constantly making small adjustments to ensure everything burns as cleanly and efficiently as possible. It acts like a shield, helping protect the catalytic converter from overheating, and ensuring it works properly. If this sensor goes bad, your engine can run too rich (too much fuel) or too lean (not enough fuel). You’ll notice if it’s really bad – things like a check engine light, rough idling, poor gas mileage, or even trouble starting. Even a slightly off sensor can gradually hurt your fuel economy and performance. You can find these pretty easily, places like Fixparts Online carry a good selection, and getting a new one isn’t usually too expensive considering how much it affects everything else. It’s a small part with a big job, really. Highly rated and reliable: PRESSURE SENSOR (MPN 0261230600) includes a 12-month warranty!
