i threw a code today and it came out to be code 32, baro circuit sensor, can anyone lead me in the right direction to fix this? ive never even heard of it. what does the baro sensor do? thanks in advance

 

Just a FYI -

code 32 can mean more than the baro sensor...

"32 Barometric Pressure (BARO) Sensor circuit failure
OR Exhaust Gas Recirculation (EGR) valve diagnostic switch - closed during engine startup or open when EGR flow requested by ECM
OR EGR / EVRV (Electronic Vacuum Regulator Valve) "

- taken from http://www.tradervar.com/GM_Codes.htm

Hope this helps!

 

my service manual says code 32 = "EGR SYSTEM FALURE" for the 5.0 and 5.7

there are two pages of diagnostics for it. i am not going to type them all out. but perhaps somone with a scanner will scan em in for you. or you could buy the book. best $35 i ever spent.

 

ok thanks for the help. i havent had EGR for almost a year now, i would be surprised if thats the cause. i guess ill put a scanner on it tomorrow and find out what the real problem is.
