Hello, I received the P1281 code on my 02 dakota V6. I replaced the t-stat with a 195 temp fail safe, the code returned. I replaced the coolant temp sensor again the code came back. I haven't flushed the system in sometime which I dont think that would could the returning code but... I received info from a mechanic to change the fan clutch. Thanks to this great site; the downloaded Service Manual tells me to check for a free spinning fan. The fan appears to have good drag and at best spins once or twice. At this point, I'm stuck.
