HelloCustomer/p>

No,it will NOT hurt your vehicle.This code is when the computer has analyzed the input (engine) 0/2 sensor readings & compared it yo the post 0/2 sensor readings as your engine is running down the highway.This code just says that the converter is not doing the proper job.

does that mean I need to replace the o/2 sensors?
No the problem is usually the catalytic converter.
