Code 32 (egr)
I checked the codes with an OTC scanner and it showed a 32 then a 45. I cleared them and not too long after the code 32 came up. It tool longer for the 45 O2 sensor to show up so I am assuming that it
is the EGR that is triggering it. It showed the EGR closed at idle and open when under load and this too is normal but still the code 32 is
showing up. I know it could be a bad connection on the solenoid and only know of one that also goes to the canister and the throttlebody.
I need help. This is a 1990 Vette.
Thanks

Code 32 occurs when the EGR valve is given the signal to open, and the MAP voltage doesn't change. Code 45 is set when the O2 voltage remains greater than .7 with the throttle 2% open or more for 30 seconds. The two codes may or may not have causes in common. Pull out your FSM and follow the trouble shooting charts. Chances are neither the O2, the EGR valve, nor the MAP are the cause(s) of the problems. Organized, methodical trouble shooting and component testing will lead you to the fault(s) without throwing money at the problem.
