What happens when the catalytic converter is clogged?

A clogged catalytic converter prevents your engine from breathing properly. As a result your car may experience a lack of acceleration and overall performance. You may also notice the fuel economy drop. Excessive exhaust back pressure can choke the engine, causing it to stall.

Is the catalytic converter part of the car?

Opinions expressed by Forbes Contributors are their own. Most of the time, people don’t even know it’s missing. Then they start their car and hear a noise that sounds like an erupting volcano, and all the birds flee the trees.

How can you tell if your car has a bad catalytic converter?

Idling on a healthy engine, the gauge should read 18-22 inches of vacuum idling in park or neutral. Wear safety glasses and remain clear of moving parts while you have an assistant raise the engine speed (still in park or neutral).

What should the catalytic converter pressure be at idle?

Typically, an engine at idle should have 1.5 PSI at most. Of course, some engines can go way higher, but the rule of thumb is to have 1.5 PSI and below. Less than 1 psi is optimum. When you rev the vehicle at 2,000 RPM and it remains steady at or below 3 PSI, then you likely don’t have issues in your catalytic converter.

What does check engine light mean on catalytic converter?

The check engine light will come on if it’s below this threshold, determined by oxygen sensors that are located before and after the catalytic converter. The sensors will trigger an Onboard Diagnostics (OBD) trouble code that’s stored in your car’s computer. OBD Code P0420 means the catalyst system efficiency is below the threshold.

How can you tell if your catalytic converter is clogged?

These issues could indicate a clogged catalytic converter, restricting the flow of exhaust out of the engine. 2 A sulfur or “rotten egg” smell. 3 rattling noise when starting the engine 4 Failing the annual or semi-annual emissions test 5 Vehicle warning lights.

What makes a catalytic converter make a rattling noise?

Rattling noise. Rattling noises are another symptom of a bad or failing catalytic converter. If a catalytic converter becomes old or damaged internally from excessively rich fuel mixtures, the catalyst coated honeycomb meshes on the inside of the converter can collapse or break apart, causing a rattle.

How does a catalytic converter work on a car?

Its purpose is to superheat unburned particles in the exhaust gases that are expelled from the engine. As the engine runs, the catalytic converter warms up to an operating temperature of 500-1200 °F. At this temperature the particles in the ‘dirty’ exhaust are burned and converted into water vapor and carbon dioxide.

Is it possible to bypass a catalytic converter?

A catalytic converter is essential to your vehicle’s emission system; it functions by transforming “raw” exhaust into less environmentally damaging gases. There are few instances in which it is allowable to remove the catalytic converter and install a bypass pipe.

Where does the name catalytic converter come from?

The name catalytic converter was derived from its operation. Utilizing a catalyst combined with heat to convert the unburned gases into fully burnt gases. This catalyst is heated by the engine exhaust to excite the chemical reaction.
