Catawba drivers book oxygen sensor replacement with Wrench Rescue because it's finished where the car sits. Coming up US-70 to Catawba is a normal run for us, and Catawba County is squarely inside our hour.
Why Catawba drivers book mobile oxygen sensor replacement
The town of Catawba is just across the river from Iredell on US-70, well inside our closest service ring. 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
