OK....have had a service engine soon light on in my 99 K1500 Suburban 4x4
for sometime now. Took it to AutoZone to have scanned. They scanned and
gave me a code of P0430 and said that could be everything from a catalytic
converter to a loose muffler clamp! Lot of good that did! Can anyone
narrow that code down more or help my narrow it down?
First of all these are not techs at AZ, they read codes and that is it.You
will need to have a " real " scan done by a qualified tech to look at o2
sensor readings on a graphing type scanner, the code refers to cat bank 2
which should be passenger side cat if you have 2. A bad pre or post cat
sensor could cause this, as well as a bad cat. There are other issues much
morewinvolved that can set this code also.
I guess you have a problem then.
SAE defines it as a bank 2 cat efficiency code.
(since it is a P0 code, it is SAE defined )
My Mitchell On Demand defines it as a bank 2 cat efficiency code.
AllData at the shop up the street defines it as a bank 2 cat
My GM OBD2 factory training manuals define it as a bank 2
My aftermarket OBD2 training manuals define it as a bank 2 cat
i-ATN defines it as a bank 2 cat efficiency code
Pages and pages of Googling P0430 point it out to be a bank 2 cat
So, 'zactly what blinky doo-dad it telling you it's a cam
position sensor code?
And while we're at it, what does your blinky doo-dad define a
