Catalytic Converter Diagnostics and Replacement in Pewaukee

Professional Exhaust and Emissions System Testing from Experienced Local Mechanics

Our Pewaukee auto repair shop provides catalytic converter diagnostics, exhaust inspection and replacement for foreign and domestic vehicles. The catalytic converter reduces harmful exhaust emissions by converting pollutants into less harmful gases. Converter efficiency depends on correct engine operation, proper air-fuel control and an exhaust system without leaks.

A catalytic converter code does not automatically mean the converter itself should be replaced. Engine misfires, fuel-control problems, oil consumption, coolant contamination, oxygen-sensor faults and exhaust leaks can all reduce converter efficiency or damage a new unit. Our Waukesha County mechanics test the complete system so the underlying cause can be corrected before unnecessary parts are installed.

What are the signs of a catalytic converter problem?

5 Symptoms That May Require Catalytic Converter Service

A restricted, contaminated or inefficient converter can affect performance, emissions and fuel economy. Have the vehicle inspected when you notice any of the following:

1. The check-engine light is on: Codes related to catalyst efficiency require proper testing of oxygen sensors, fuel control and exhaust integrity before replacement is recommended.

2. The vehicle has poor acceleration: A converter that is internally restricted can limit exhaust flow and make the engine feel weak, especially under load.

3. Fuel economy has decreased: Engine-management problems that affect the converter can also cause the engine to use more fuel.

4. You hear rattling beneath the vehicle: A loose internal catalyst substrate or damaged heat shield may create a metallic rattle.

5. There is excessive heat or an unusual exhaust odor: An overheated converter can produce strong odors and extreme underbody temperatures that require immediate inspection.
