code 12

My other thread was closed but for good reason, sorry spikeymike. OK I have done the research and didn’t come up with the anser I am looking for. I have a 91 teg, manual, and I am throwing a code 12 which is EGR Control system. From what I already knew and researched is that the EGR valve only came on autos. So I am asking myself why in the hell am I getting this code??:shrug: The only thing I came up with is that the ecu is for an auto but then again I thought you had to have a manual ecu for an manual transmission car. Can some one please help me with this b/c I am lost.

Ok sorry every one found that yes technically you can run a auto ecu but it wont run a 100% right. So now my question is by looking at the ecu how can I tell if it is for a auto or manual?

This may help:

Thanks man, I guess I’m not using key words on my searches…lol

For those wondering:

For a manual OBD0 ECU one set of these should be the last 3 in the code…

000, 001, 002, A00, A01, A10, J00, J001, C01, C00

For an auto OBD0 ECU one set of these should be the last 3 in the code…

J51, J50, A50, A51, 901, A60, C50, C51, X30, A80, L50, L51

For a manual OBD1 ECU one set of these should be the last 3 in the code…

000, 001, 002, 003, A00, A01, A02, C00, C01, C02, J00, J01, J02, G00, G01

For a auto OBD1 ECU one set of these should be the last 3 in the code…

J50, J51, 901, 902, C50, C51, C52, A50, A51, A52, L50, L51, G51

Looks like you have 2 manual OBD0 ecus and 1 auto OBD0 ECU, lastly 1 auto OBD1 ecu.
