Oxygen Sensor for 2003-2005 Mercedes-Benz C230 - Bosch 17242

Bosch 17242 oxygen sensor for the 2003-2005 Mercedes-Benz C230 4-cylinder 1.8L measures the air-fuel ratio in the exhaust and reports it to the ECU. As a wideband A/F sensor, this Bosch O2 sensor gives the ECU more detailed readings than a traditional switching sensor.

• Continuous air-fuel ratio measurement across the full lambda range
• Planar pump-cell design with ceramic construction and optimized heater control
• Reaches operating temperature in under 7 seconds for quick closed-loop control
• Withstands exhaust gas up to 1,880°F, with an integrated heater element and TSP coating against vibration, corrosion and contamination

A worn oxygen sensor can show up as a check engine light, poor fuel economy or a rough idle, though other faults can produce those signs too. If a failed sensor is the cause, this one replaces it. Before replacing it, look over the wiring and connector with the engine off and cool, because damage there can mimic a bad sensor.
