What do the codes 12 32 and 41 21 13 14 13 5 mean for a Dodge 318 Dakota 5.2 liter engine?

Answer 1

According to Haynes Repair Manual for 1987 to 1996 Dodge Dakota pickups,

• 12 means memory standby power lost. (The battery was disconnected recently).
• 13 means MAP sensor vacuum circuit. (This will activate the check engine light).
• 14 means MAP sensor electrical circuit. (This also will activate the check engine light).
• 21 means Oxygen sensor circuit. (This activates the check engine light on California models).
• 32 means EGR system. (This activates the check engine light on California models).
• 41 means charging system excess or lack of field current.

All codes are two digits, so the code 5 must be incomplete. 15, 25, 35, 45, 55, and 65 are all possibilities, however, if it was the last code output, it is most likely code 55 which simply means that the list of fault codes is finished. All code output lists are started by code 88 and ended by code 55.
