OK I figured out how to jump the connector. It 12,12,12 then 36,36,36, and finally 45,45,45 then began to repeat. I looked up the codes in a Haynes manual.

12 = ???
36 = MAF grounding problem
45 = replace O2 sensor - exhaust too rich.

I couldn't find a code for 12. Any Help would be appreciated.

 

code 12 is basically letting you know that the ecm is functioning. If you had no other codes it would only flash 12

 

thanks

 

Code 12 is basically just a code saying there is no distributor signal. Normal code that all flash first.

 

code 12 actually means Diagnostic Mode
