#346 of 467 Hard restarting
Jul 05, 2009 (11:18 am)
I have a 1993 dodge dakota with a 3.9 liter v-6. The check engine light is
on. I turn the key 4 times to get the trouble codes. The codes I have gotten
are 22, 23, and 45. I have replaced the coolant temp sensor, the throttle
position sensor, the intake ambient air temperature sensor, the Oxygen
sensor, the pcv valve , and the air intake filter. The engine is hard to
start. After the engine is hot and I kill the engine, trying to restart is
hit and miss. Sometimes it will start right up and other times it won't.
Then it will act as if it is flooded. It won't idle. I rev the engine a
little and the rpm's will finally kick up to around 1500. Then the engine
will run smooth. The codes I get now are 45 and 22. I can't understand what
is going on. Any help will be greatly appreciated.
Also, is the heater/AC blower resistor located in the engine compartment on the R/H firewall on a '93 Dakota? Thanks.

I have the same pickup, the same problem started a few weeks ago for me. I have had it into the shop twice now and they can't find anything wrong with it, seems to cure itself each time I've brought it in. My next call will be the dealer I bought it from even though I have to drive 75 miles, hopefully they will recognize the problem, they are a Dodge dealer. From reading other info online I might try replacing the throttle body sensor before running to the dealer. Good luck!

#350 of 467 97 Dakota powerloss/backfire issues
Jul 20, 2009 (7:29 am)
I read through these boards before posting, but i didnt find an answer to my problem, I have a 97 dakota sport, 3.9 auto, 2wheel drive. A few weeks ago it started dropping RPMs and losing power while driving, warm or cold it didnt matter. Would also happen stopped at a light as well. I replaced the plugs, wires, cap/rotor, and when that didnt do it i replaced the map sensor. Worked great for 3 days, then it seemed like once the engine was heated up it was fine, but that only lasted for like 2 days. Now its just random, i could drive to work and home, then go out later and it could die, the rpms just drop, theres a low backfire sound, more like a putt, then a backfire. sometimes it stays running, sometimes not. Ive looked for bad ground connections. Visually checked for any kind of vacuum leak. The O2 sensors were replaced 2 years ago. It has a exhaust leak somewhere near the engine but i didnt think it was major enough to cause anything like this. Any help on tracking down whats doing it would be great. thanks
#351 of 467 '96 Dakota, Engine Sluggish, PCM Problem?
Aug 04, 2009 (7:21 am)
1996 Dakota SLT, 5.2l V8, automatic, 2WD. Engine has been sluggish the last few months, gas mileage down, auto trans wants to quickly shift through gears up to 4th and lock converter.
No MIL light. Scanned with 2 different scan tools and found only pending misfire DTCs. However, several of the sensor outputs as read through the PCM look strange. Have factory service manual and ran diagnostics on MAP sensor, TPS, ... The sensor output voltages look correct (MAP output Vdc vs manifold pressure). Example,engine OFF, manifold pressure 29.8 in. Hg, MAP output voltage 4.5 Vdc (OK), but PCM says manifold pressure is 9.0 in. Hg (via scan tool). Same problem w/ engine idleing (true pressure 11 in. Hg, PCM says 2 in. Hg). TPS also way off (PCM says 73% open when WOT). Long term fuel trim (7%) indicates some lean mix. Reset PCM by disconnecting power for 15 min. No improvement in MAP or TPS reading. Trans not shifting up as fast - better.
Checked sensor voltages at sensors and at plugs into PCM. No differences. Also checked all splices in sensor lines (5Vdc, sensor output, sensor gnd), all OK.
Question: It sounds like the part of the PCM that reads the sensor voltages (analog-to-digital converter circuit) isn't working right. Anyone else have these kinds of symptoms? Can PCM partially degrade like this? Thanks
#352 of 467 Dodge Dakota '94 - Losing Power, Oil Pressure

#353 of 467 Dodge Dakota '94 - Losing Power, Oil Pressure
Sep 29, 2009 (8:59 am)
I have a 1994 Dodge Dakota 4x4 V8. 103,500 miles. Low miles for such an aged vehicle.
Recently, the engine has been sputtering at 2000 RPMs and losing power, and when I punch the accelerator to maintain power I get an occasional POP. From time to time, the Check Engine light comes on at the same time that the loss of power is experienced. As I said when I lose power the engine does tend to sputter. Eventually the engine does recover for a time.
At low idle, the Oil Pressure gauge drops to low left and the Oil Pressure light comes on. Dipstick shows that I am burning oil, however I check and maintain the oil level religiously and change oil and filter every 3000 miles.
I've noticed that Dodge trucks seem to have this low oil pressure problem. However, the loss of power seems to be something much more sinister.
Anyone have some insight before I drop 3 grand at the dealer?
#354 of 467 throttle position sensor 2001 4.7L V-8
Oct 04, 2009 (10:33 am)
recently replaced the TPS as I was having surge problems when cruise control or sometimes just throttle engaged manually around 45-50 miles per hour. Would surge with rpms and then return to normal. After replacing TPS got engine trouble codes P0122 and P0123 stating has TP sensor circuit is low input and high input. I am just getting codes from my on board trouble code not using specialized scan tool. Two questions one can the TPS be put in wrong? Does the PCM have to be reset by using the specialized scan tool and will this correct the trouble codes. I did take the truck out for spin and notice My cruise control does not work now? Any suggestions? thanks Header1974

Does anyone know once you replace the TPS Throttle Positioning Sensor how do you reset PCM and eliminate the trouble codes. After changing the TPS I still get P1022 naP1023 codes with onboard computer? Does it have to be reset by dealer to know if new TPS is working? Will this effect the cruise control? thanks for any help you can provide Header1974
