cel on after driving

[jdawg901]

i have had help on this problem with the codes and figured out what it is its the coolant sensor but it dosent come on until truck gets to operating temp but when i turn it off and restart it goes off again until i drive a minit.but it dosent come on when i let the truck sit an idle a while.when i first checked codes i got 15 and 32 after getting much needed help from this forum found out it was the (15)coolant sensor and(32)egr disconnected the batt replaced the sensor reconnected the batt light went off for a while recheked the code now only 15 shows could there be another problem associated with this code other than the sensor

It is either a bad sensor or an open circuit...you already replaced the sensor so let us go with the open circuit.

Have you checked the wiring for it and all the grounds? After that I would test the voltage at the sensor and at the ECM.

Wiring. Trace the wires, look for shorts.

No problem, make sure you solder those connections and cover them up real good.
