I have a 2000 Dodge Grand Caravan and my problem is the check engine is on. And the trouble code is P0420. I have changed the EGR valve, O2, and the cat converter. The check engine light did not came on after a new cat converter was replaced, after 800.00 dollars!
I am having a trouble code of P0420 on my 2000 Dodge Grand Caravan. The O2 has been replaced so with the EGR valve and cat converter. But the cat converter was just a after market. What must be the problem why the check engine light is coming on even the code has been erased? Thank you very much.
