Trouble code 55 really isn't a trouble code at all. It indicates the END of the trouble codes. If that is all you are getting, then there are no codes stored.

Easiest way to reset the PCM is to pull the possitive battery cable for 30 seconds to a minute. Of course, you loose your radio presets and whatnot. If you prefer, just pull the fuse for the PCM out of the fusebox for the same length of time and replace. I don't know the exact one, but there should be a diagram on the fuse box door, or nearby the fuse box.

What do codes P0411, P1000


P1000 code means the codes were cleared or the battery was disconnected
Powertrain Control Module (PCM) Reset Description All OBDII scan tools support the powertrain control module (PCM) reset.
The PCM Reset allows the scan tool to command the PCM to clear all emission-related diagnostic information. When resetting the PCM, a DTC P1000 will be stored in the PCM until all the OBD II system monitors or components have been tested to satisfy a drive cycle, without any other faults occurring. For more information about a drive cycle, refer to Drive Cycles .
The following events occur when a PCM reset is performed:
  • Clears the number of Diagnostic Trouble Codes (DTCs).
  • Clears the DTCs.
  • Clears the freeze frame data.
  • Clears diagnostic monitoring test results.
  • Resets status of the OBD II system monitors.
  • Sets DTC P1000.

P0411 Secondary Air Injection System Incorrect Flow Detected

neither of these could cause a no start or no crank problem . Is the battery good an do you have good connections on the battery ? Do the headlamps show bright when on ?

I have 1993 dodge dakota 3.9l v-6 with trouble codes 12,15 and 55 what do they mean


the trouble codes are as follows code 12 problem with battery connection. direct battery input tp pcm disconnected within the last 50 ignition key-on cycles. code 15 a problem with the vehicle distance/speed signal. no distance/speed sensor signal detected during road load conditions. code 55 completion of fault code display on check engine light. this is an end of message code. the speed sensor is located on the transmission/transfer case extension housing. check plug connection to speed sensor for power using an volt meter. connect the positive side of volt meter to the orange wire terminal and the negative side of volt meter to the black/light blue terminal. the voltage should be approximately 8.0 volts and to check the voltage from the pcm connect the positive end of volt meter to the white/orange wire terminal and the negative side ti the black/light blue wire terminal. signal voltage should be 5.0 volts. if there is no signal voltage signal, have the pcm checked out. if you have both signals from the terminals then remove the vehicle speed sensor and check the speedometer pinion for worn or missing teeth.

1993 dodge dakota 4*4 codes are in order as


12= Standby memory power lost
27= PCM to injector failure
15 = No VSS reference
55 = Completion of fault code display

With the given codes and the way it is running I would say that you are having either a issue with the PCM ground and or the main connector to the PCM. Intermittent failure in the plug would cause these cascade codes with a misfire.

I would inspect the plug and make sure there is a good verifiable ground from the cab to the frame even to the transmission itself. The cabs of these trucks have notoriously bad grounding. Best to establish a new one rather than chase the old one and assume it is ok. Small gauge wire with terminals will suffice.

You may also be noticing that the volt and temp gauges go up and down slightly with the turn signal when it is activated? Radio may also freak out at louder volume settings if the ground in the cab is compromised.

Trouble Code 3255


Hi,

Thanks for using Fixya!

1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

2. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32.

A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition for a neon.
CODE Description of Trouble Code
11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles
13 No change in MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02s sensor problem (oxygen sensor), upstream or down stream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range
25 Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found
27 Injector control circuit
31 Evap purge flow monitor failure or evap solenoid circuit
32 EGR system failure
33 A/C clutch relay circuit
34 Speed control Solenoid circuits
35 Rad Fan control relay circuit
37 Torque converter clutch solenoid CKT or park/neutral switch failure
41 Generator field not switching properly
42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal control failure
54 No Cam signal at PCM
55 End of error messages (If you get this only, no errors were found)
62 PCM failure SRI mile not stored
63 PCM Failure EEPROM write denied
64 Catalytic Converter Efficiency Failure
65 Power steering switch failure

So in your case, you are getting error 3255 right? so you are getting error 32 EGR system failure and 55 which is no other error found.

I hope you get this sorted out.
Have a great day sir.

Trouble codes


Trouble Code: P0139
O2 (B1 S2) Slow Response
Trouble Code Conditions:Engine started; vehicle driven at 20-55 mph with the throttle open for 2 minutes; ECT at more than 158ºF (70C); catalytic converter temperature is more than 1112F (600C); and EVAP purge is active. O2 Sensor signal voltage switches less than 16 times from lean to rich within 20 seconds during monitoring, or will compare the state of change between the front and rear O2 Sensors and if the differences are greater than a calibrated amount, the DTC will set. 3 good trips are required to turn off the MIL.
Possible Causes:
  • Exhaust leak
  • O2 element is contaminated, deteriorated or it has failed
  • O2 signal circuit or return circuit has failed

Trouble Code: P0344
Camshaft Position Sensor Circuit Intermittent
Trouble Code Conditions:Engine cranking or running; system voltage over 10.5v. The PCM detected an intermittent loss of the CMP Sensor signal during the period of 2.5 complete engine revolutions. The failure counter must reach 20 before this code matures and a code is set.
Possible Causes:
  • Wiring harness fault
  • 5v supply circuit open or shorted to ground
  • Tone wheel/pulse ring is damaged or corroded
  • CMP Sensor has failed
  • CMP Sensor signal circuit is open, shorted to ground or battery voltage or 5v supply
  • CMP Sensor ground circuit is open
  • PCM has failed
  • Trouble Code: P0340
    No Camshaft Position Sensor Circuit Failure
    Trouble Code Conditions:Engine cranking or running, system voltage over 10v. The PCM detected CKP pulses without detecting any CMP Sensor pulses for 5 seconds or 2.5 engine revolutions.
    Possible Causes:
  • CMP Sensor connector is damaged, open or it is shorted
  • CMP Sensor signal circuit is open or shorted to ground or to battery voltage or 5v supply circuit
  • CMP Sensor 5v supply circuit is open or shorted to ground or to battery voltage
  • CMP Sensor ground circuit is open
  • CMP Sensor is damaged or has failed
  • CKP Sensor is damaged or has failed
  • PCM has failed
Good luck....
