Default 1990 OBD Code 32

My 1990's check engine light came on. I'm getting an OBD code 32 "right rear toothed wheel frequency error". This code is for 1990 and 1991 only. Has anyone had this issue and how was the fix?

I thought 32 was EGR? Where are you getting that info?

My bad. I looked at the ABS codes instead of the engine codes. I should have known a wheel sensor would not set a check engine light. The 32 code actually relates to either the barometric pressure sensor?: or the EGR valve diagnostic switch. I'm thinking I may have a vacuum hose leak at the EGR valve..

They don't have unique codes.

If you are getting it through the flashing engine icon, it is an EGR issue.
