90lum31v6euro Posted February 27, 2004 Report Posted February 27, 2004 ive got the 3.1, and im getting code 62, and it stumps me my haynes manual says that it is the trans gear switch circut, but it also says that it only applies to the quad 4 and the 3.4 the other code 62 in the book is the cruise control vac selonoid and it only applies to the 3.8. I know its not this one because i dont have cruise, and i dont have a 3.8 so im stuck, like usual Quote
gmrulz4u Posted February 27, 2004 Report Posted February 27, 2004 The Haynes could be wrong, it appears that Code 62 means: Vehicle gear commanded by ECM did not match actual gear selected. However, I don't quite understand because most sites don't show it for the 2.8L, but do for the 3.1L? Maybe GM added it in late 1989? Quote
gmrulz4u Posted February 27, 2004 Report Posted February 27, 2004 Are you 100% SURE that you counted that code right?? Because I just logged into ALLDATA and it specfically does NOT show it for a 1990 Lumina 3.1L Quote
90lum31v6euro Posted February 27, 2004 Author Report Posted February 27, 2004 yes i counted it out right i watched the code 4 times to be sure six flashes, then 2 flashes no mistaking it Quote
Slade901 Posted February 28, 2004 Report Posted February 28, 2004 That might be 26 error code. Check it again. Watch carefully after the 12 code flashes 3 times and then the actual error code. Flash pause Flash Flash, Flash pause Flash Flash, Flash pause Flash Flash and then the error code. I made an error like that reading the error code which I ignored the first digit 2 because I thought it was part of the 12 default diagnostic code. Quote
90lum31v6euro Posted February 28, 2004 Author Report Posted February 28, 2004 ok, lets say that i did screw it up and it is flashing 26 what is the quad driver circut and what does it do code 62 being the trans gear circut sounds more likely ill check it again tomorrow Quote
90lum31v6euro Posted March 1, 2004 Author Report Posted March 1, 2004 its definatly code 62 no doubt about it it still doesnt make sense Quote
