Error code 32

[Hellbillie]

Recieve error code 32 when i`m using ac. or when the outside temp. is rising, like summer/spring.
SES lamp starts when going under 1500rpm crusing, and goes off over 2000rpm. Or the lamp starts with the car stopped/engine running and transmission in D or R for some seconds, goes off when trnasmission is put in N or P.
This error seems to disapper during the cold season.
Does anyone know how to re program a ECM in order to get rid of the EGR function?

You need to replace the ECM chip with a heavy duty "F" program.

I've been running with one from John Kennedy for five years with no trouble. Bill Heath has them as well.

Thanks Charlie

I will try that.

I unplugged my EGR valve yesterday, plugged the line, and expected to get an EGR code this morning on the way to work. I didnt though. Any ideas ?? Maybe I can put a plate under my egr valve and get away with it. Mine is a 96 1500, with egr, but no mass airflow sensor.

Hello Scooby
I don`t know why, but mine is more or less the same. It seems to depend of outside temp., or if i`m using AC. During cold season, i can go for months whitout any SES.
