Check Trottle Lever Error

[Fran San]

I am having troubles with my Volvo D4-260 EVC-C with CHECK THROTTLE LEVER FAULT. I have had a Volvo technician out many times as the problem is intermittent. The Volvo technician had many theories and changed a few things, reloaded software and still the problem exists so I had an electronics specialist come in and he noticed when he would wiggle the communications cable from PCU to the HCU at the HCU he could make the error come and go. We used a test cable between the two and still the problem exists. Can anything be done to correct this issue? All pins look clean with no sign of oxidation. Any thoughts? ERROR codes on display MID 164, PPID 392, FMI 4 I have a Four Winns with twin diesels and only the port engine errors. Thank you in advance.

Just guessing but using a new cable at it still happens when wiggeling cable at HCU, I would think its the HCU connector. How the connector makes connections inside the unit
