My pump seems to be running internittantly. I have seen temps on IA @ reach 190 degrees. Then after several miles...It starts falling....I plan to check it out tomorrow but am wondering what sensor turns it on. Seems like I heard the ECM cuts it on above 50 degrees. Not sure , anyone Know for sure ?
thanks

Here's the factory settings for my 03:

intercooler pump engine speed turn on 16383 (ignore this one)
intercooler pump min ACT for control -256.0000 (air temp AFTER blower)
intercooler pump min ACT to turn on 70.0000 (same as above)
intercooler pump min ambient turn on -1024.0000
intercooler pump min battery volt for on 10.0000
intercooler pump min load turn on 1.9999
intercooler pump min on time 600.0000
intercooler pump time turn on after start 20.0000

The above are either degrees or seconds depending on if they describe temp or time. The IAT2 sensor controls a lot of it. That is located on the second runner back on the passenger side right next to the blower on my 03.
