ACDelco 12634085 - Heated Oxygen Sensor

GM Original Equipment

SKU: 12634085

An ACDelco GM Original Equipment Oxygen (O2) Sensor is a GM-recommended replacement for your vehicle's original component, and is a special feedback sensor on your vehicle's exhaust system. This sensor measures the proportion of oxygen in the exhaust gases. Using this measurement, the engine management computer can adjust the air/fuel ratio near the optimum value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. This original equipment oxygen sensor has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Availability: Will be special ordered for you.

FAQ

Q: Can I replace an ACDelco Oxygen (O2) Sensor on my own?
A: Yes, but with today's computerized engine systems, maintaining your vehicle's exhaust and emissions system is best left to a professional technician.

Q: Is there a problem when my 'Check Engine Light' turns on?
A: Yes, it could be due to a contaminated sensor probe, broken sensor body, internal sensor failure, or external electrical failure.

Q: Can ACDelco Oxygen (O2) Sensors help provide better gas mileage for my vehicle?
A: Yes, ACDelco Oxygen (O2) Sensors are the primary devices on your vehicle that measure the proportion of oxygen in emission and gases with the amount in outside air. Using this measurement, the vehicle computer can adjust the air fuel ratio to the optimum value of 14.7:1. At this ratio engine performance, emissions, and fuel economy are optimized.

Maintenance & Troubleshooting

Good Maintenance Practices:

With today's computerized engine systems, maintaining your vehicle's exhaust and emissions system is best left to a professional technician.

When replacing oxygen sensors it is important to use GM OE parts. Parts that do not meet GM OE service specifications, such as element type or cover design, can be detrimental to emission controls. Increased nitrogen dioxide emissions, higher exhaust gas temperature, misfires, or loss of engine power can result from using non-compliant sensors. This can also lead to engine component failure caused by overheating of the catalytic converter.

It is critical to ensure that you have the right part with the right wire length for your vehicle. Excess wire can be exposed to extreme heat and abrasions that can lead to premature wire failure. ACDelco Oxygen (O2) Sensors use the correct sensor components that GM has validated to engine specific applications.
