great video very informative and to the point 🙏
This looks like it was hard to film. Thanks for doing it to share with the world!
Really appreciated this video. Never would have found this sensor without it. I even got the same wrong sensor when I started this fix. Anyway, it went from barely running with two engine codes (coolant and tps) to running really well again after replacing just the coolant sensor and no codes. THANKS
That's what happened with mine. I'm happy it helped you out! 🍻 -Al
Thank u for this video. Helped me to realize I have every socket available… EXCEPT FOR A DEEP WELL 13 mm🤦♂️🤦♂️🤦♂️🤦♂️. Good video.
Awesome! You are welcome.
I bought a 1995 Dakota with a 2.5. I really like it,trying to get all the kinks out of it. It had been taken care of fairly well.
Great! Electrical issues are the most common problems with these trucks as they age. 30 year
old wiring now. Before you replace a sensor, make sure you have no wiring issues. Some of
my codes were bad wiring to the computer. I've had mine 4 years now. Good luck with your
Dakota, they are great trucks to drive. Cheers! 🍻 -Al Cox
@bigalsmallengines Ya I found that out. Mine was occassionly not cranking,like no juice from the battery. Luckily we found a hard to see bare ground wire. I teplaced the starter,ignition and battery. It has a few small electrical issues now,like after awhile the wipers will come on by theirselves. I cant complain overall,I paid $1000 for it and it runs really good. Just a spare vehicle and something to do some hauling in.
@@andyr8625 Around a thousand is what I paid for mine. It had been parked for a while.
I have actually replaced my computer and went through the 50 wire repair of the Computer
Module Connector. That was the first thing I done that made 5 or 6 codes dissappear.
That was quite a job though to replace that connector. After that I still pulled codes for
this sensor and I had a code for a lean condition. I replaced the fuel injectors and put new
connectors on the ends and had my first oxygen sensor replaced. So far after a year, all is
good. This is a daily driver for me actually so I just stay on top of the maintaintence now.
If anything else happens to it, I will make more repair videos, but hopefully no more... LOL.
@bigalsmallengines Ya I was thinking about possibly replacing the computer before we found the problem. Mine never did throw any codes. Boy you can have endless possibilities of what the problems might be,hard to diagnose.I started replacing parts that didn't really need replacing. Its a crap shoot sometimes,lol.
@@andyr8625 Yeah I quickly found out that one of those codes could be 5 or 6 different
things...LOL You could certainly start throwing money at a code. I found that when I
moved that computer connector around, it made differences in the way the truck run.
I tried to clean the connector but it made no difference, so I ended up thinking it was the
Computer and replaced it. But it turned out to be the connector and I had to get another
connector from a junkyard and spent a day splicing the wires back to it...LOL Mine rides and
drives real smooth is what I like about it. I am around 180 thousand miles, I hope it will
last a good bit with the prices of trucks out there now. I use mine daily so I just try to stay
on top of it with maintainence for now. Great to hear from you! I hope you'll comment
back on here later and let me know how it's doing. 🍻
65 and doing the same thing now. If not for you alerting me on the 1 or 2 pin connectors, I would have been screwed by the clerk selling me the wrong sensor. There is a 1-pin and a 2-pin sensor for that switch in that year model. Be careful when ordering parts.
Would this make the temperature gauge in the truck not work?
This sensor has nothing to do with your temperture guage.
It is a sensor for the ECM to monitor the engine's coolant temperture.
If it is defective, it may be telling the ECM wrong info, thus changing
the way it manages the engine run. A code 22 will tell you to check it.
IF your guage don't work, it is either the sensor for that guage, wiring
problem or the guage itself.
Would that make it run rich and stall out? I am having that issue and code 22 and 17 both states coolant temperature sensor.
My ‘89 LA V6 runs rough too, and it has thrown the coolant temp sensor code. Still runs and drives but jostles me a bit at stop lights. Going to try this once my husband will let me touch it again. I spend so much time on that truck because I love it.
Yes, your issue would be with the sensor shown in this video, but the sensor itself may not be the problem. The issue is most likely going to be a loose connection at the sensor. The best thing to do is test the sensor first by checking the resistance across the terminals with the engine cold to see if it is reading accurately. At 70°F, it should read ~10k ohms. If the temp is higher, the resistance will be lower and vice versa.
Part number?
Coolant Temperture Sensor-OEM # is REPD312801.
If you buy it at a parts store, I highly recommend you take the
original with you to make sure they give you the right one.
@@bigalsmallenginesok thank you
