Oxygen Sensor

Refine Results

Oxygen sensors are part of the fuel and emission system of your car. These sensors gauge the amount of oxygen in the exhaust and send the data to the engine computer to adjust the air-fuel ratio based on the reading. MoparOnlineParts offers 100% authentic OEM oxygen sensors at discounted prices.

Monitor Your Air-Fuel Ratio Using OEM Oxygen Sensors

Oxygen sensors monitor the air to fuel ratio in your engine. These sensors are mounted in the exhaust manifold to analyze the exhaust gases from the engine. The sensors will then send the reading back to the engine control unit (ECU) and adjust the ratio accordingly. The ECU will increase or decrease the amount of fuel depending on the air-fuel mixture reading to achieve the optimal A/F ratio. Too little air in the mixture will result in wasted and unburnt fuel being expelled to the tailpipe, while too much air will burn the fuel slower and irregularly, causing power loss. 

Oxygen sensors are still prone to wear and tear, causing dips in overall vehicle performance. Faulty O2 sensors can cause your check engine light to turn on. Some sensors can still function even if they have numerous issues but will often fail to maintain the optimal emission levels and fuel consumption of the vehicle. If your car starts to have poor fuel economy, less power, rough engine idling, and misfires, have your oxygen sensors checked and replaced immediately.
