Anyone know what the resistance across a new or known good IPR solenoid coil should be. Mine's measuring 13 Ohms. The truck keeps throwing a p01211 for low ICP. The ICP isn't terminally low, running around 450-475 @ idle. Never builds beyond 2300 at WOT acceleration.
I have a Superchips Flash Pack and keep the engine set for max performance, otherwise the fuel system is stock. I've thrown 1211's before under very hard acceleration but it's throwing them consistently now, every drive. Methinks something is going south and I'm trying to get in front of it for a change.
Thanks in advance for any assistance,
MDH

 

Electromagnetic Coil Test: OHMS = 10.2 - 10.6

 

If you think about how the IPR works, it is much like a continuously operating old fashioned door buzzer that runs whenever your truck runs. Only it is pushing against up to 3600 psi of super hot oil. It is not hard to imagine that device starting to fail after thousands of miles. In a similar way the HPOP is a hard working machine that can wear, especially if the oil is allowed to get a little dirtier than it should. So, is it possible that your HPOP is showing signs of wear and cannot keep up under full throttle?

Why not replace the IPR, then see if the problem goes away? If not, look at the HPOP.
