Q: Error message on my dash

asked by on

I changed my catalytic converters but I didn't change my 02 sensors now I'm getting error messages on my dash do u think it might be from the aftermarket cats or not changing my sensors

My car has 92000 miles.
My car has an automatic transmission.

The aftermarket catalytic converters may not be working as well as the factory ones. A scan of the vehicle’s computer will allow a technician to look at live data from the oxygen sensors to determine if the sensors are faulty or if there is a problem with the new catalytic converters. Diagnostic trouble codes may help indicate the origin of the problem. A certified technician, like one from YourMechanic, will be able to scan your vehicle to determine the exact cause of your concern.
