I recently purchased a 2013 Toyota Corolla from Cotonou, but the check engine and track off light are on. After scanning I was told that the catalytic converter was removed.

Presently, there are no issues with the car, and a full tank takes me about 400 miles before it goes into reserve. That's an average of 30 mpg combined.

I want experts in the house to advise if it would be necessary for me to purchase and install the catalytic converter and what the added advantage would be.

Hello guys. Please can the absense of catalyst in my car affect the fuel economy. I bought a Toyota rav4 2010 V6 and I discovered that the cats have all been removed, but the car is seriously chopping my fuel. Thank you

play the videos to understand, you will notice thats most car has two o2 sensors one before the catalstic converter and one after

these monitors exhaust gases meaning the 1st o2 sensor measures values of exhaust gases straight from the engine then the 2nd o2 sensor measure values of exhaust gases after going the Catalytic Converter (cleaning process of exhaust gases) those reading from the o2 sensors should be within range specificed in the ECU if not thats will trigger a check engine light that might be related to o2 sensors or Catalytic Converter

so a missing Catalytic Converter can trigger the ECU to increase fuel ratio therefore your mpgs can drop
