Why O2 Sensors Are Important

Oxygen sensors measure oxygen in the exhaust and provide information to the vehicle’s computer. Depending on their location, they help manage the air-fuel mixture or monitor catalytic converter performance. A faulty sensor may contribute to poor fuel economy, increased emissions, or rough running. These symptoms require testing because other problems can cause them, too.

Signs Your Vehicle May Need O2 Sensor Service

Schedule a diagnostic appointment if you notice:

• Check Engine Light: A warning that requires diagnosis to identify the cause.
• Reduced Fuel Economy: More frequent fill-ups without a change in driving habits.
• Failed Smog Inspection: Results indicating an emissions-system concern.
• Rough Idle or Hesitation: Changes in how the engine runs.
• Unusual Exhaust Odor: A noticeable change that warrants inspection.

Bring any recent diagnostic or smog inspection paperwork to your appointment. This information can help our team understand what has already been checked.
