Hey Guys, I have a 03 HL w/2.4 ltr
I have a CEL code p0420 bank 1 and p0430 bank 2
What does this mean? and which one is bank 1 and 2
I have a scanner and cleared the code to see if it comes back and frezze data will tell Me if it does it during the same condition.
Thanks

You can PM me your VIN and I can double check, but there was a TSB for P0420 & P0430 which is obsolet because it is covered under a Special Service Campaign(SSC) 60I. Any dealer can run your vin to see if your vehicle is applicable or not and it entails reflashing the computer.
