'93 lumina 3.1 SES light came on while on the highway tonight. Pulled the code...32. "exhaust gas recirculation circuit"???? what is that??

The egr system is not operating as expected by the pcm, bad valve , clogged passages are some possibilities.

I want to make sure I did this right. I put my code key in the diag. connector (terminals A and B). I thought the SES light was supposed to flash several times to let you know it's working correctly. Well I turned the key "on" and the SES blinked once then twice....once then twice....once then twice....then gave the code 32 (3 blinks...pause...2 blinks). Did I do it correctly? The only reason I ask is because I thought it was supposed to flash several times before it spit out a code. There is no code 12 is there? Thanks

once then twice is 12, is it not?

oh yeeeaaah!!! duh! I just thought that the last time I did it, the light blinked several times (like 12) rather than showing 1 then 2 flashes. What would you recommend for the 32? thank you

Check for clogged passages to and under the egr, confirm egr operation, you will need a scanner to do this properly. check the connections at the egr also.

Thanks
