Descriptions: 

• The oxygen sensor measures the amount of oxygen in the exhaust gasses that exit the engine. 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.

?

???Can a bad O2 sensor cause loss of power?

• A faulty O2 sensor relays false readings to the computer causing inaccurate adjustments to your combustion engine’s intake and fuel system. These conditions cause inaccurate shifting points directed by your car’s transmission control module. Incorrect timing and fuel injection affect the fuel combustion responsible for efficiently running your vehicle. Inadequate combustion eventually translates to a lack of sufficient power for acceleration and other engine functions.
