Why Lexington drivers book mobile oxygen sensor replacement
Lexington is barbecue country on I-85, east of Salisbury. It's at the edge of our hour, and we still make the run. That's exactly the situation mobile fuel & exhaust work solves: the mechanic comes to the vehicle, so a car that shouldn't be driven doesn't have to be.
What's included
Oxygen sensors tell the computer how to mix fuel. When one gets lazy or its heater fails you get a check engine light, worse mileage, and eventually a failed emissions test. We confirm the sensor is actually the problem — not an exhaust leak or vacuum leak — and replace it with an OEM-quality sensor.
- Read the code and live sensor data
- Check for exhaust leaks upstream of the sensor
- Remove the old sensor (heat and penetrant if seized)
- Install the new sensor with anti-seize, torque to spec
- Clear codes and verify the sensor is switching
Signs it's time
- Check engine light with an O2 or heater circuit code
- Poor fuel economy
- Rotten-egg smell from the exhaust
- Failed emissions test
- Rough idle
