This answer was rated:

1998 chevy truck has trouble code p0430 catalyst system efficiency below threshold(bank2). will it hurt to drive I will be pulling a boat.I pulled my boat to the river today and it seams to pull ok or do I need to take it to some body before going on vacation next week?
Welcome. What size engine and are there any other codes?

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.

Customer: replied 7 years ago.
does that mean I need to replace the o/2 sensors?
No the problem is usually the catalytic converter.
