Question
How to test faulty automotive catalytic converter?
Answer
Measure exhaust backpressure and test converter efficiency.
Explain
A faulty catalytic converter causes reduced engine power and increased emissions. CHEPQ exhaust backpressure gauges measure pressure (<2 psi at idle) and efficiency tests (CO2 increase >10% after converter)—replacing the converter ensures emissions compliance and engine performance.
