What Is A Code 430 On A 95 Ls400?

Recommended Posts

Just had the check engine light pop up, and Advance pulled a code 430 on my 95 LS400. Something related to either the O2 sensor, or the CAT. What side L or R is that, as well as Front or Back??? Apparently the car has 4 O2 sensors.....

P430 LS400 Catalytic converter failure

my 97 did the same thing at 246k I replaced the two front converters. no more problems.

I got mine from mufexpress on ebay they are $115. each and a perfect fit see #320535514532

good luck... they are not hard to put on.

OH, still driving it, still no lights

PS o2's hardly ever fail, they just read the gas that flows thru and tell the ecm if the cats are working.. mine didnt
