Emission Control Parts Features
Information
A GM Genuine Parts Original Equipment Oxygen (O2) Sensor is a GM-recommended replacement for your vehicle’s original component and is a 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 specific GM vehicle, providing the same performance, durability and service life you expect from General Motors. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
- Detect oxygen content in the exhaust gases to optimize emissions and fuel economy.
- GM-recommended replacement part for your GM vehicle’s original factory component.
- Offering the quality, reliability and durability of GM OE.
- Designed, engineered, and tested to rigorous standards, and are backed by General Motors.
Warranty
24-Month/Unlimited Mile Limited Warranty.
FAQ
- Can I replace an Oxygen (O2) Sensor on my own?
-
Yes, but with today?s computerized engine systems, maintaining your vehicle?s exhaust and emissions system is best left to a professional technician.
- Is there a problem when my “Check Engine” light turns on?
-
Yes, it could be due to a contaminated sensor probe, broken sensor body, internal sensor failure or external electrical failure.
- Can GM OE Oxygen (O2) Sensors help maximize the gas mileage for my vehicle?
-
Yes, GM Genuine Parts OE 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
- 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 noncompliant sensors. This can also lead to engine component failure caused by overheating of the catalytic converter.
- It is critical 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. GM Genuine Parts OE Oxygen (O2) Sensors use the correct sensor components that GM has validated to engine specific applications.
