Motor stalled or low power then runs good P2290 Code
After having the oil/egr cooler replaced about 6 months ago the truck has been running good but then last week it shut down once while idling at a stop light, seemed like a fuel starvation at first. Restarted right up. It did this once more when leaving my house about 2 days later. I put my scangauge on it and had a pending P2290 code so I set it up to monitor some of the sensors, ICP pressure, %, and sensor voltage. The ICP sensor voltage looks within range normally (.8V at idle, well above 2V under acceleration). Ran it on the highway yesterday after clearing the code. Ran well then seemed to have low power (not sure if it was in "limp mode" or just not getting enough injector pressure). The sensor voltage did drop when I had the low power condition the other day but this could be due to actual low pressure as opposed to a bad sensor.
If the HPOP is on the way out, does this sometimes start out as an intermittent thing? It would seem that it would just gradually get worse or quit. The intermittent nature seems more like an electronic sensor? Or if it is intermittent does this point more to the IPR?
Its running fine again now but I guess it's only time before it happens again or gets worse.
Anything else relevant I can look at with my scangauge? Truck is a 2006 with about 118k.
