Guys, I'm getting codes P1448 & P1451 from a 1997 355 Spider. Does anyone know the def. of these codes and possible causes? Thanks, Chris
P1448 - Catalyst bypass flap circuit - malfunction P1451 - Secondary air pump circuit - short to ground
You are the man! I have got my 1997 F355 down to the last code p1445 something about the secondary air, though not entirely sure. My electric blower motor runs fine and I have vacuum going to the plastic valve right next to it. I guess I should check to see if it is opening. Does any one have any info on the exact code definition or what to check??
Make sure the filter material is not clogged up...there was a recall on that...make sure yours has been taken care of.
