Oxygen Sensor Replacement in San Carlos, CA

Toole’s Garage in San Carlos provides comprehensive auto care for cars foreign and domestic. Oxygen sensor replacement is among the numerous automotive repairs we offer. Oxygen sensors play a vital role in your vehicle’s operation, so oxygen sensor failure needs to be corrected in a timely fashion.

Oxygen sensors monitor content of gases leaving the combustion chamber, as well as the gases leaving the catalytic converters. Some high performance engines are designed with an oxygen sensor for every cylinder. Oxygen sensors live in a harsh environment – they are bathed in hot exhaust gases, and are bombarded by particulates in the exhaust stream. This harsh environment causes the sensors to degrade and eventually to fail. Over the last few years, catalytic converter theft became an additional cause of oxygen sensor replacements – when thieves cut out a catalytic converter, thee often damage other components, and oxygen sensor systems are the most frequent “collateral damage”.

Signs of a failing oxygen sensor can include poor mileage, rough idling, even stalling, and the check engine light will come “on”. If your car is due for a smog test, it will likely fail the test. If you notice any of the above symptoms, we recommend getting your vehicle to a professional auto repair shop in a timely manner – driving with a failing oxygen sensor may result catalytic converter damage, and replacing catalytic converter is an expensive repair.

At Toole’s Garage in San Carlos we will inspect your vehicle, scan the codes stored in the onboard computer and let you know the root cause of the problems your vehicle exhibits – and if the oxygen sensor turns out to be the culprit, we will not only replace it, but will also check your vehicle for coolant or oil leaks, since they can damage the new oxygen sensor.

So if you notice that your vehicle’s mileage has suddenly decreased, if you notice black smoke from the exhaust, or the check engine light comes “on”, it’s time to look up your friendly “mechanic near me” and bring your car in for a professional inspection.
