I have a dome sensor reading erratic intermittently. Meaning while at zero psi, cruising down the roas or sitting still, it randomly spikes to a number then floats around while no pressure is in the line or commanded.

Facts:

-Holley Dominator ECU , 100 psi regulated c02

-The issue repeats with a known good sensor and the original new sensor I was trying to use. Even if the sensor is just sitting there not in the wastegate hat -I’m positive that my Mac valves are working correctly and plumbed correctly bc when the sensor reads correct the system works correct both stagnant, in garage or on the track.

- circuit is pinned correctly

- I have 4.98 ref voltage -.02 ohms resistance on low ref circuit to ground

-.02 ohms resistance from signal to ecu pin (just in case, ran a new circuit externally and pinned it to an unused 5volt ref (A26) and sensor ground (A18) at the J2A connector and even tried putting signal into a different input pin at ecu (input was J2A- A10 ...it is now A11) and no change..

- Recap: circuits tested good...... verified and replaced redundantly (just to be extra sure it isn't a failing circuit the fault was not showing currently) two sensors repeat issue (one new sensor and one known good) ...... ecu pin was also ruled out by swapping pin in connector J2A and in software (Pinmap) .... when the circuit reads correctly boost modulates as expected. not a boost control issue but a dome sensor issue..... the data log is available and looking over the moment it goes from 0 psi to a false reading in particular, i dont see any other sensors reading weird or anything. battery voltage seems clear, and the car runs fine and all else on board, just this one sensor

My thoughts are the computer is having an internal issue, or the 5-volt ref circuit has a bad sensor or similar but i THINK that would cause other sensors on that circuit be weird, correct me if im wrong and I'll try to isolate it 5-volt ref wise and then ground wise.

**I am curious if the Holley uses one 5-volt reference for all the inputs available or does it spilt them between multiple 5-volt drivers like a factory ecu. isolating cam sensors and crank-sensor to 5-volt ref circuit 1 and the pressure sensors for the engine on say 5-volt ref circuit 2...???

** My question is obviously what is wrong????

I am scratching my head here and wanted to ask you guys! Thanks in advance for any input here.

(I tried to attach log file but it will not allow so I posted a screen shot of the log, happy to email it direct to you if you find necessary to see it closer.)
