When your Mitsubishi Sigma left the factory, it was destined for a driver who values economical pricing in their automobile. Your Mitsubishi dealership isn't the only place to buy trusted parts to repair your Sigma.

What Oxygen Sensor does for your vehicle.

Achieving maximum power and fuel efficiency with your car or truck depends on your use of properly functioning air and fuel delivery parts. The fuel-injection system on your Mitsubishi Sigma is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Mitsubishi Sigma oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and it will likely be emitting an excess of hazardous exhaust.
