Why Oxygen Sensor replacement is so important.

Achieving maximum power and fuel efficiency with your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your Mercury Monarch is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Mercury Monarch 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 emissions from your tailpipe may be in excess of legal levels.
