Ok guys I need some help on finding out these codes.

23 Mat Sensor Low voltage (Probally the relocation to the front air duct)

33 MAP Sensor High voltage

51 Faulty or improperly installed ECM PROM
I have switched ecm's (I have a spare) and memcals still comes on

41 Cylinder selection error (checked the firing order and it looks good)

I want to solve code 51 because it might help with others..

Any help would be appreciated

Thanks

 

sry i cant hlp much but id say your right about fixing code 51. good luck

 

Reset, run, repeat pull.





No, not that kind you dirty old men! You know who I'm talking to!

 

Tryed that and no luck.. I wish someone in the area had the same car and could swap memcal's

 

Your code 41 and 51 go hand in hand. Basically they mean to open the case on the computer and make sure that the computer chip is properly installed and doesn't have any bent or broken pins. It also means check to make sure you have the correct chip in there to start with.
