What is an ho2 sensor

Une sonde lambda aussi appelée sonde à oxygène est un capteur destiné à mesurer le taux de dioxygène d’un gaz. Elle est souvent installée dans l’échappement des moteurs thermiques afin de contrôler la qualité de la combustion en mesurant la teneur... Wikipédia

What does a ho2 sensor do?

It sends real-time data about the amount of unburnt oxygen in the exhaust system to the engine's computer to determine the correct air-to-fuel ratio for the car's engine.

Where is the ho2 sensor located?

The O2 sensor is normally located on the exhaust manifold near the catalytic converter. In newer cars, there are usually two oxygen sensors for each catalytic converter (one before and one after). Older cars typically have a single oxygen sensor. Some modern vehicles have even more sensors!

Is an O2 sensor a serious problem?

If you ignore the signs of an O2 sensor issue, your catalytic converter is likely at risk and could potentially cause further damage to your vehicle if it quits on you. A service that could run you a couple hundred (depending on how many oxygen sensors your vehicle has) could now cost $500- $2,000 more.

What happens when O2 sensor fails?

If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine's timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.
