1992 Plymouth Voyager CHECK ENGINE

Hi there,

Thank you for the donation,

On checking these codes I find that 12 is an indication that the batteryor ECU has been disconnected with in the last 50 Starts, this is not a problem, code 27. "Â 27 Injector circuit isn't switching when it's told to (TBI)
OR (MPI) injector circuit #1 not switching right
OR (turbo) injector circuit #2 not switching right
OR (all 1990-) injector output driver not responding
- check computer, connections.

Code 55. Indicates end of code read.

So No 27 is the problem that you need to investigate, as the notation states, you need to check the ECU and the plug connections first.
