p1488, p0236, p0522, p0122, p1693
hey guys I've been chasing this problem since last week. driving home from work throttle was surging in and out. checked with scanner and found p0122 for app and p0522 low oil pressure, and now the oil pressure gauge always shows 40psi even with koeo. i have been driving it around it goes about 40mph at best but takes forever to get there. i was starting with the 5v reference code and found on all related sensors i am getting over 6.15 v and i tried 3 different meters. i just about pulled the entire engine harness out of truck no easy task when its 5 degrees f outside. i was hoping someone has been here before. I'm beginning to think ecm and not wiring. any help would be a huge relieve

Hi there I was coming back from work all of the sudden light came on and engine shots down few minutes later start up and runs normal but the light still was on. 5 minutes later again shot down at this time it takes 45 minutes to start again. I drove 30 miles to get home everything was normal even I could go 70 mph. Conected to code reader and got DTC P0236 P1690 P0234 but my truck still starting and running normal even with the engine light on.any idea what is going on? :scare2:

I always Now start with ALL grounds, I didnt believe it but after $1000s of new parts I discovered my main problem was bad Grounds, it will make the computer tranny,torque converter, and fuel pump, etc. etc .etc GO CRAZY, almost sold the truck:

Check batteries for corrosion and terminal ends. I recently had to replace my driver side because of no start issues. These things get pretty emotional when it comes to grounds. Also check for AC noise coming off the alternator.
