I give up. After messing with this I still cant fix it. I changed both pressure sensors and the air box temp sensor. Keeps throwing codes 13 14 20 23. I tried to reset the codes but the last part where you drop the thumb warmer switch down to clear does not work. It is possible that the problem is fixed since it runs ok, is thee any other way to clear the codes?

Do you have a ground block issue? Those can throw up multiple codes. When mine first had issues it would still start and run at first. Although the handwarmers didn't work. Later it would not even start.

Did you ever confirm what @74Nitro had requested which was to confirm if the two sensor share a common wire? Sure sounds like an electrical issue and knowing the ground blocks have been a known issue to cause all sorts of electrical gremlins, between the two sensor's sharing a common wiring and tracing that and those ground blocks is where I would focus my attention.

I spoke with Nitro today and I will investigate the wiring issue this weekend
I had a similar problem on my 08 Apex GT , code 11, 13 and 23. Wouldnt run because of code 23.
A few months ago I checked the upper grounding blocks and they looked new, so I kind of didnt bother to check the rest since the problem was intermittent, but then suddenly it was there all the time. It was one of the grounding blocks close to the ECU.
There are 3 blocks and one thinner block on the harness close to the ECU.
Disconnect the harnes all the way from the battery/regulator/ECU and pull it up/out, then unwrap the blocks and remove the black plastic shield over the blocks and pull out the pin-connector inside of them. Mine had had some corrosion in the grounding block, I cut the block off and soldered the wires together - problem solved!! I also removed the other blocks and soldered them together. (even though I think atleast one of them actually is a positive lead). I also removed the little block with only 4 wires into it and soldered them also. Then put heatshrink with glue on them and taped back into harness.
Good luck
