Code 12 | No distributor reference pulse (diagnostic test active) |
I’m guessing the new carb may be throwing different signals and readings to the ECM - perhaps relearning? I know their not the new smart cars, but do they relearn new computerized parts added?If you get a 12 code while driving, it's a problem. But during the diagnostic tests, you expect it. This means it is in active diagnostic mode and communicating with the ECM. If this is the only flashing you get, then that's good. Means no driveability codes. If it does, listen to what 79 USA 1 is telling you.
If you're not getting any other codes, then probably not. The TPS setting on the different carb may cause a code, but you should have seen that by now.I’m guessing the new carb may be throwing different signals and readings to the ECM - perhaps relearning?

How long should I expect to see this flashing? I’ve turned it off and on /started and each time has been flashing with no following codeI’m guessing the new carb may be throwing different signals and readings to the ECM - perhaps relearning?

It’s flashing upon starting the engine and following. - I’m sure it would flash if I just turn the key on and didn’t start but didn’t do that yetIt will flash each code 3 times before moving on to the next. If you are only getting the code 12, with the key on but engine off, then it is nothing to worry about.
