Hey Guys, I've been a member since 2003 I believe but never really posted. I recently brought my camaro back out and dont plan on parking it for months at a time anymore, now that i've recently got her running A LOT better than when I first got her. Years of hell but I never gave up on her. Anyways I have the following Codes Being Thrown:


12 - No reference pulses to Electronic Control Module (ECM). (No Idea What That One Is About)

24 - Circuit fault in vehicle speed sensor (I know what that ones about, when my uncle took my trans out, he broke the connection part off, never got it replaced.)

36 - Burn off at mass air flow sensor OR Problem in transmission shift OR Fault in direct ignition system OR Missing pulses in electronic spark timing signal (Pretty Sure i know what this is about, wires to connector had gotten chewed up by alternator band, Rewired it years back but not sure i rewired it too accurately)

44 - Oxygen sensor lean (Caused by Mass Air Flow Being having a faulty connection, right? computer compensating falsely)

54 - Low voltage at fuel pump OR Low voltage at Fuel pump relay OR Output failure at quad driver module (Not sure exactly what this is about but It takes me about 3-4 cranks to actually get my fuel pump to turn on. I replaced fuel filter last week.)

 

12 is always supposed to be there. I think it just means the your diagnostic port is working. I would fix the 24 code, replace whatever was broke, clear the codes and i bet the rest of your codes will go away.
