1996 Dodge 5.7L no spark. Code 1255 blinks on check engine light.

If you had two blinking CEL codes, a 12 (pause) and a 55, the code 12 means the battery has been disconnected within the previous 50 starts. The code 55 indicates the end of stored codes. Therefore, you have no saved trouble codes (disconnecting the battery deletes saved trouble codes).

Generally a blinking check engine light indicates a cylinder has a misfire. Could be a bad spark plug, spark wire, coil, or injector.

Hello there, I have a 91 dodge grand caravan and by the looks of it, you used the key on, key off, key on, key off, key on method to get those codes. If so, 12 is one code(number of key ons since last fault)(direct battery input to controller disconnected within last 50 too 100 ignition key ons), And for code 55, its just the completion of faultcode display on the check engine light. So basically, there is nothing to worry about. * *NOTE*-All information came right out of Haynes repair manual for 84-95 Dodge Carvans

Hi there:
DTC P1255 - Pedal Correlation PDS2 and LPDS Low

It's when there is the wrong voltage between the electric throtlle body, and the electric gas padle assemblys. Either there is something wrong with the throttle body electric motor, the gas padle was disconnected, or there might be something else Im overlooking.



You need to be aware that some diagnostic equipment can put out spurious fault codes which are extremely misleading.



Hope this helps.

i`m not sure what the code meaning is but if you put gas down the throttle body and it runs then you have a fuel problem which this code may refer to.this year of truck is fuel injected throttle body.it could be a fuse,fuel pump relay,fuel pump,plugged fuel filter,stuck open fuel pressure regulator not building enough pressure,wiring for fuel or pump system or even a computer(ecm) problem.

Good Evening, I don't remember seeing a p9303 code, but a p303 is a misfire code on cylinder 3, I would tell you to double check your plug wires and definitely make sure #3 is sparking. Also be sure to check the spark plug gap since you just put it in that it is possibly a little off. Hope this helps.

A code 42 is the Auto Shutdown Relay Control Circuit....The ASD relay is located under the hood in the Power Distribution Center next to the battery. Change the ASD relay, that should fix you up. If that doesn't work...you might have to check the PCM. But replacing the ASD relay should do it.

Bryon

that is two codes, niether mean any problem, here are the difinitions,
12 Battery Disconnect Direct Battery input to PCM disconnected within last 50 ignition key-on cycles. Normal if battery has been disconnected, otherwise check battery power and ground connections


A DTC 55 is used to end all DTC messages. This code does not show on the DRB tool and indicates a completion of the stored codes on the Malfunction Indicator Lamp (check engine lamp).

code P0304 is a cylinder missfire code and means that there is a problem with ignition to that cylinder check the spark plug and the spark plug wire

According to Allpar.com code 12 is "battery disconnected in last 50 starts" and code 55 is "end of codes"
