You need a scan tool.
Vehicles use generic codes, enhanced codes and manufacture-specific codes. So you must use a shop manual to get the codes used in your particular vehicle.
turn the key from off to run (not start) three times leaving it in run the last time the digital odometer will flash the alpha numeric codes then read "done" after the codes have been displayed
Cylinder #1 misfire
You need a scan tool to read fault codes.
On a '92 Dakota: Code 12 = standby power to the computer memory has been interrupted or lost. Code 22 = a fault in the coolant temperature sensor circuit. Code 24 = a fault in the throttle position sensor circuit. Code 55 signals the end of the codes that were stored; there are no more stored codes. Loose electrical connections and sometimes loose vacuum hoses can cause fault codes. Check for these problems. If you can correct them, the codes will be erased after five (I believe) successful re-starts.
Trouble code P0441 means: EVAP Purge Flow Monitor Fault
scanning for codes will indicate if the CPS is at fault.
Since it is OBD11 it requires a scanner to retrieve the codes. Most parts stores will read then for free. you can use a car scanner to clear it out.
Fault code 16 means: Loss of battery voltage.
