Previously, we posted part one of this two-part post. Providing you with clarification about specific auto repair shop terms in which you might have a hard time understanding what they mean. Here, we provide you with some more terms and offer up additional explanation and suggestion regarding these terms.

Anti-lock Braking System (ABS) – While this is a term that you probably hear a lot regarding cars or repair, some of us might not know what the ABS does. This system helps drivers maintain steering control, for example on a slippery road surface, by preventing the wheels from locking up. Pay attention to your anti-lock brake warning light; if it comes on while you’re driving, that signifies a problem that should be checked by your NARPRO mechanic as soon as possible.

Check Engine Light – This is another fairly common term, and while most of us have had an experience with our check engine light, we might not know what it means when this light comes on in our dash – some of us might even ignore it, and think that it’s not a big deal! Most often, this light appears when your car’s engine computer (ECM) detects a problem. The problem can be minor such as a loose gas cap, or a much bigger issue, such as an engine mis-fire. Whether small or large, check engine light occurrences are often related to emissions issues.

Oxygen Sensor – Also known as the O2 sensor, this part measures the amount of oxygen in the exhaust gases; some cars can have up to four O2 sensors. This sensor feeds info into the ECM which is then used to keep the ratio of air and fuel entering the engine at an optimal level.

So next time you have to visit the repair shop, whether it’s for routine maintenance or an unexpected issue, remember to read over this list first, and you will have a much easier time understanding what your mechanic is telling you!
