Engine light came on. When I chkd code by turning key 3x, I got P0237. How do I clear the code so that after I disconnect the Quad module, I can see if that was the problem? If not the Quad, I assume its the MAP sensor. Anything else I should consider? By the way, where's the MAP sensor located?thx,Eric

Map sensor is on the driver side of the block, almost to the back, just behind the fuel filter housing. Without clearing the code, you will have to just let the key cycle, I think it's 40 times. Did the truck act up, loose power? Usually you will have no power with bad map.

No, I've noticed nothing unusual at all.

Try this too... Run the diagnostic to verify everything. http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/59-obdii-error-codes/167-p0237-map-sensor-voltage-too-low

Mine will throw this code sometimes. It is touch and go with me. One time the light is on and all is fine and still build good boost the next time the light can be on and the turbo will not spool at all. When the person that had truck before me put the Edge on they broke the map sensor plug and it vibrates lose a little I guess. I put some dielectric grease in the connector and put a zip tie around it to try and solve but it still does sometimes.

You should be able to buy the receptacle plugs through Cummins or the dealership

I know but how much are they gonna cost lol I'm broke with me moving 60 miles away lol:broke:. I thought about changing them out to a Weatherpak connector but will still have the one on sensor that I can't change
