I idle long enough with the hood open to see the intercooler tank start whirling.....I have a data reader at all times, and it has a PID for the intercooler pump SCIPC: 1 active 2 inactive. I relied on that and use to never think about it, until one day I saw my IAT2 climb to 175 just while cruising. I was like WTF? PID says 1 active.
Pulled the car over and sure as sheet the IC tank was not flowing. So the PID is nothing but a dummy light just simply indicating the computer has told it to run.....but thats not a guarantee it is. I jumped the IC box with a wire and the pump started flowing, so I got lucky and only needed a new relay. $10 back working. But lesson learned. I check before leaving the garage every single time.
