97 Ram 5.9l has two sensors....not sure if both are cts or what. My motor blew up so I swapped in the 5.9L out of my 98 parts truck which only has 1 cts sensor. Swapped all wiring off the old engine and put on the new one. Just that one sensor is missing. CEL is ON probably due to the coolant gauge not working. Any ideas on what to do here? Thanks

 

ttt.....need to drive my truck....please help

 

What ever was on the 97 as far as coolant sensors, swap it to your new engine. if the 97 computer is looking for two.... use the two you had.

 

on the older models, one of the sensors operates the gauge, and the other talks to the pcm. there's a long post about it within the last week or so, including which is which.

what your truck wanted you to do was remove the intake from the 97 engine and put it on the 98. what you may have to do is look for a capped off plug, or drill and tap a new hole, or just run one sensor, probably to the pcm, and let the gauge not work, or maybe rig the gauge in another manner. sounds a little late, and not worth the trouble, to swap the intakes.

 

definately a little late to swap the manifold....could I use the single sensor and tap into the wires?

 

i don't know. here's a couple of threads.

havent really been able to find any info as to what to do....whether I can tap into the single one or not....I dont know what kind of signal it sends....hmmm

 

i'm not sure if there's enough room to make this work right, but you might build a T that will screw into the manifold, and allow you to screw in both sensors. wires might need extending and it'll look like $hit, but it would work.

 

thats true...didnt think of that.....who cares what it looks like as long as it runs...Im the only one under the hood anyway

 

the single wire runs your gage which shouldnt throw a CEL.....im not sure if a t would work that well or not.......you could fab up a pipe with a bung and splice it in your heater hose to put it at......
