This sensor is responsible for measuring the oxygen content in the exhaust gases after they have passed through the catalytic converter. If this sensor is not functioning properly, it can cause a variety of engine performance issues.

Possible Symptoms:

  • Illuminated check engine light

  • Decreased fuel efficiency

  • Rough idle or stalling

  • Reduced engine power or acceleration

Possible Causes:

  • Failed oxygen sensor

  • Faulty wiring or connections in the circuit

  • Loose or corroded electrical connections

  • Failed engine control module (ECM)

  • Exhaust leak

Related Parts:

  • Oxygen Sensor: This is one of the parts that fails very commonly. It measures the amount of oxygen to ensure proper combustion. Problems in the Oxygen Sensor lead to poor fuel economy

Possible Solutions:

  • Replace the oxygen sensor

  • Check and repair any damaged wiring or connections

  • Tighten or clean any loose or corroded electrical connections

  • Replace the engine control module (ECM) if necessary

  • Repair any exhaust leaks
