Check engine light on with p0430, had it reset put some catclean in, drove for 150 miles about 160 mph check engine light did not come back on. But the p0430 comes up.

You didn't reset a thing

You cleared all data needed to diagnose the issue

Google your codes: OBD PO430

You will see you have a failed exhaust converter

Now you have to resolve the reason it failed,
before replacing it,they should last 15 years

Obo2 code of p0430

Go to or have it taken to a mechanic shop/vehicle fix-it shop and have them do a diagnostics check on the vehicle computer. Tell them the code shown and they should be able find the issue. If doing on your own the best solution would be to replace the O2 or oxygen sensor first to see if this eliminates your problem. If not, replace your front catalytic converter and oxygen sensor.

Forgot to mention, this is done without your vehicle requiring a basic tuneup (spark plugs, oil change and maybe spark wires, etc.).

I have a code P0430 on a Lincoln after changings all coils on a 2004 Lincoln V6, what caused and How do I fix it?

P0430 is Catalyst System Efficiency Below Threshold (Bank 2).

A code P0430 may mean that one or more of the following has happened:

  • The catalytic converter is no longer functioning properly
  • An oxygen sensor is not reading (functioning) properly
  • There is an exhaust leak

First, inspect for exhaust leaks.

Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen sensor while you're at it.

Re: Engine light is on after changing spark plugs

Go to autozone and have the code scanned. And come back here to ask more question. Otherwise you are wasting money.
