The 12 is normal for the starting code. The 41 says generator (alternator) field is not switching properly. Code 45 says Turbo boost limit exceeded (engine was shut down by logic module). I doubt that you have turbo on the Dakota. However there IS a code 46. Battery voltage too high during charging or charging system voltage too low. That would make sense with the 41 code. Sounds like you may have an alternator/charging system problem.

code 36 air switch solenoid circuit non turbo or wastegate solenoid circuit on turbocharged models.
code 46 battery voltage too high. code 53 module internal problem SMEC SBEC failure internal engine controller fault condition detected. code 54 problem with the distributor synchronizer circuit.

READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

That is an OBD1 System

Your code reader won't work

You need OBD1 capable reader or
the adapter for an older scan tool

The connector is in the engine compartment

If you need to know where, I will look in my
1992 manual as I departed with my Dakota
june last year.

If you get code I will look them up for you
or tell me the problem your having.

I think the connector is hanging near the
A/C expansion valve on pass side

OBD Code 12 - No Distributor Reference Pulse (Diagnostic Test Active) The Engine Control Module-ECM uses the distributor reference pulse to calculate the engine speed. On newer engines, the Crank Shaft Position Sensor performs this function.

Symptoms:

• When flashing the Check Engine Light to read codes, code 12 will always display first, indicating the diagnostic system is active
  
• The engine will not run with a "hard" code 12 set
  

Common Problems:

• Chances are you will never need to diagnose a code 12. Rather, the problem would be a crank, no-start condition.
• If code 12 does not flash, that would indicate a communication problem with the ECM.
• Code 12 does not show when reading codes with a scan tool. If there is a communication problem, the scan tool will let you know.

OBD Code 46 - Pass-Key II System Error - Circuit out of Frequency Range The ECM receives a signal from the Pass-Key module. When the correct signal is received, the ECM will allow the engine to start and run. Please review the RepairPal article on the GM Pass-Key Anti-theft systems for more information.

Symptoms:

• Engine may not start

Common Problems:

• Faulty ignition lock cylinder

OBD Code 43 - Knock Sensor error The ECM receives a signal from the Knock Sensor based on the amount of engine ping detected. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

Symptoms:

• Engine ping
• Lack of power

Common Problems:

• Faulty Knock sensor
• Poor connection at Knock sensor

OBD Code 55 - End Test.


Hope ehit help (remember comment and rated this).

Codes are usually 3 digits and will start with start with a letter...P(Powertrain), B (Body), C(Chassis) or U(undefined).
The majority of codes are power train codes and I looked at P046 and there is no such code.

The fastest way to find out the problem is go to an auto parts store and ask them to use their code scanner. They tpically will do this for free and then tell you what the codes mean.

Fuel fail 46 is emission related and if I remember is related to the oxygen sensor/catalyst. I would reset the code by disconnecting the battery for 45 second and if it comes back on then start with a proper diag.
DO NOT REMOVE THE BATTERY TERMINALS UNTIL YOU MAKE SURE YOU HAVE THE RADIO CODE
Your welcome to email me with any other issues and if you dont have the radio code

i would not worry about the code 47 the code 46 is a pcm communication problem that is what turned the light on the power steering usually will not turn the light on i would check all my fuses first for the code 46 is there any other noticeable problems like with heater or a/c that may help me help u solve the problem

Code 46 is indeed the trouble code for the Idle Speed Controller which is that big black box thingy on your throttle body. A lot of Chilton-type manual books omit that code because the ISC isn't found on pre 94 Metros. The ISC is a computer controlled auto-adjuster for the engine idle.

An important note: code 46 is often caused by misadjusted distributor timing. As you probably know, timing affects the idle, and if improper timing moves the idle beyond the ISC's adjustment range, the check engine light will come on and diagnostics will return code 46.
