Code 13 on a 96 Dakota is usually the MAP sensor circuit, check the vacuum line to it first before replacing the sensor.
The truck acted like it wanted to die on a restart.....pushed on the gas a bit and it started and ran. Do you know where to buy a MAP sensor these days if needed?

11 No ignition reference signal detected during cranking (bad Hall effect) OR timing belt skipped one or more teeth; OR loss of either camshaft or crankshaft position sensor. Can cause the engine to stop working entirely with no limp-home mode.
12 Battery or computer recently disconnected
13* MAP sensor or vacuum line may not be working
14* MAP sensor voltage below .16V or over 4.96V
15 No speed/distance sensor signal
16* Loss of battery voltage detected with engine running
17 Engine stays cool too long (bad thermostat or coolant sensor?)
17 (1985 turbo only): knock sensor circuit
--------------------------------------------------------------------------------
21 Oxygen sensor signal doesn't change (stays at 4.3-4.5V). Probably bad oxygen sensor
22* Coolant sensor signal out of range - May have been disconnected to set timing
23* Incoming air temperature sensor may be bad
24* Throttle position sensor over 4.96V (SEE NOTE #3)
25 Automatic Idle Speed (AIS) motor driver circuit shorted or target idle not reached, vacuum leak found

Thanks! Just throwing the 13.....haven't checked vac lines yet.

You sure it's 96? I wasn't aware you could do the key flip past 95? If for some reason it is OBD1 13 is O2 sensor.
According to the VIN and title, it's a 96. It also has two O2 sensors on the exhaust system...one in front of the cat and one behind it. My 95 only has one which is upstream of the cat.

Sounds like OBD2 to me. Surprised you couldnt find the code online, its everywhere. Also had no idea you could read the codes by flashes on the dash of the 96. When I had one and it gave me problems I just plugged up my $30 code scanner.
Well, don't have a scanner. Always went to an auto parts store to read and confirm what the computer pumps out. Also on the key flip....once it was done spitting out that 13 code, it gave the 5 pause 5 flash. 55 for end of code. I doubt that the auto parts stores have a code reader for a 30 year old vehicle anymore??

Everything 96 and later is OBD2 and has a port just under the dash for any OBD2 scanner. 95 and older is what almost no one has the scanner for anymore. Snapon was the only manufacture of the OBD1 scanner that I'm aware of. I was a Mazda tech when they were out.
My 95 messed up one time back when the warranty still covered the computer and anything related to emissions. It would run fine then go into limp home mode. Next day it would be fine then do it again a day later. Drove it 40 miles to a Dodge dealership where I knew some folks and the scan tool didn't pick up anything so I drove off but stayed close to the dealership after telling them that. It finally went into limp home mode again and went back to the dealership and the reader spit out every code known to man. They installed a new computer and it's been fine ever since.

Looks like you came to the right place, lots of help above. I'm back buying, fixing, modifying and selling 1st gen Daks so I'll be on here more. Will have a nice 95 for sale soon. pic of it last summer, looks a bit different now with new chrome bumper clears up front and fender flares.
