Frequently Asked Questions
The MHK501050 lambda sensor measures oxygen levels in the exhaust and supplies that information to the engine control unit so the air/fuel mixture can be adjusted for efficient combustion and emissions control. A failing sensor commonly causes increased emissions, reduced fuel economy or rough running and should be diagnosed by checking engine fault codes and sensor operation.
