Wierd ICP readings

Over the past few weeks I have been noticing my icp has been jumping up to around 950 or so after a cold start and then slowly works its way back down to around 600 ish. Koeo is 2, cranking is around 350, and starts within 2-3 secs then gets 950 then back down to 600ish after warm up. It only does it on a cold start. the rest of the day is normal start then 600ish. I have AE but have not yet watched it on a cold start only the SG2. Otherwise vehicle runs fine. I also have the refresh rate on SG2 set to fast.

My ICP on cold start will always be up higher, like yours, and depends on just how cold it is. Will determine the reading.

As the oil warms up, the ICP reading drops down.

I was wondering if the colder weather had anything to do with it. Since i have only owned the ex since aug I don't have a baseline for behavior in cold weather yet.

Oil is harder to pump when cold, therefore, higher pressures. Once everything comes up to temp the oil is easier to pump, hence lower pressures.

Mine does about the same. I see around 600 PSI once warmed up at idle.
