Delphi Oxygen Sensor P/N:ES20000
Delphi ES10678 front oxygen sensor for the 1990-1995 Mitsubishi Mighty Max 4-cylinder 2.4L and other vehicles measures the oxygen left in the exhaust and sends that reading to the engine computer. The computer uses it to help keep the air-fuel ratio in range.
A worn sensor can show up as a check engine light, poorer fuel economy or a rough idle. Before you replace the sensor, rule out an exhaust leak, damaged wiring or another fault that sets off the same warning, because those need different repairs.
This sensor fits the 1990-1995 Mitsubishi Mighty Max 4-cylinder 2.4L and the 1990-1993 Dodge Ram 50 4-cylinder 2.4L.
