SOURCE: Fuel 12/Fault 12 Error Message

check the mass airflow sensor circuit; thats what the owners manual says DTC code 12 pertains to, but to me it sounds like a fuel pump. i had the same problem, it would turn over, but not crank. make sure youre getting spark and everything else first because the fuel pump is located in the gas tank, and requires removing the entire tank to access it, which easily can turn into a 4-6 hour job.

adding If you are getting correct pulses to the injectors, you can try 3oz of acetone and 1oz of marvel oil to each 10 gal of gas your fuel for the next few fill-ups...this will safely clean injector nozzles, providing they aren't worn out or internally binding.Your injectors are triggered by the computer, so check the plugs and wiring to make sure nothing is loose or shorting. There is much more to this, but it's a good place to begin.

SOURCE: codes 12 54 55

12 means the battery has been disconnected sometime in the last 255 starts. 54 is refering to the pickup plate in the distributor, sometimes called a cam sensor. 55 is the end of the test

SOURCE: 1994 dodge truck codes 12 and 55

my source doesn't say much about these codes:
12 - direct battery input to PCM was disconnected in the last 50 key-on cycles
55- this code indicates a completion of all DTC's displayed on the check engine light

I'd guess they will eventuall go away but are not related to the starting issue

I have a 1991 Dakota it has two trouble codes on is#12 memory standby power lost the other is # 27 injector output circuit not responding what does this mean and to fix it


Code 12 is more or less common, code 27 is a problem with the injector or the circuit.
You may need to research the code 27 to get the testing procedure and the wiring diagram. Usually the reason for the code is too much resistance in the circuit or an open circuit. The computer grounds the injector to make it open.

1995jeep grand 4.0 code 12 -27-55


Code 12 = Battery was disconnectedwithin the last 50 key cyckes. Ignore this code, it is normal when the battery is disconnected.
Code 55 = Completion of diagnostic codes. 55 means end of code messages. Ignore this code.
Code 27= An output driver within the PCM does not respond to the control signal. This can be a tricky one to diagnose. It will either be the crankshaft position sensor, or the hall effect switch inside the distributor. This is the Best case senario, worst case will be an internal fault inside the PCM or a bad connection on either of the previous mentioned.

I have a 94 dodge caravan it idles fine but it is running rough engine codes I picked up are 12 and 41 and 55 do you know what these codes are. Thank You


12-direct battery input to PCM was disconnected within the last 50 key-on cycles
41-generator field not switching properly
55-end of error messages
Check sparg plugs, ignition cables, fuel system (fuel filter, injectors)

1994 dodge truck codes 12 and 55


12-- Battery or computer recently disconnected. Check the connections or, wiring harness that is connected to the CPU. Make sure it is in good condition. Check the battery post cables for faults as well.

55 is end of codes - it's normal. Before you call your dealer or mechanic, consider that the blink-spacing is not always perfectly uniform, so if you see 23 23, it's probably just a single 55. (Codes are not repeated.)
