If you find that you are in need of a new O2 Sensor, why not replace it with the same brand that your new vehicle came with? Mopar. O2 Sensors from Mopar are top of the line. Plus they are backed by a great warranty; no other brand can promise that.

An O2 Sensor works with your vehicle's onboard computer system to determine the amount of oxygen passing through the exhaust system while it's running. It automatically tells the computer to add or reduce the amount of fuel being sent to the engine until the correct mixture is achieved. This process occurs several times a second on an average car, and helps to reduce harmful emissions while improving engine performance and fuel efficiency.

A failed O2 Sensor can:

• Have you going back for tune-up after tune-up

• Seriously damage your car's catalytic converter

• Cost you the equivalent of six extra fill-ups a year, 70 gallons of gas or more, in reduced mileage alone

• Cause poor mileage or a rough running engine

If you experience any of the following symptoms, chances are you have a failed or worn out sensor:

• Excessive fuel consumption

• High emissions

• Engine surging or hesitation

• Premature failure of the catalytic converter

When examining your engine's O2 Sensor, any gummy deposits or a shiny deposit on the sensor's heat shield indicate it's time to check and/or replace the sensor.

We recommend having a service technician check your oxygen sensor on a regular basis: every 30,000 to 50,000 miles for an unheated one- or two-wire sensor or every 60-100,000 miles for a heated three- or four-wire sensor. Please check your owner's manual for exact inspection information.
