Coolant, oil pressure, rpm, and speedo all go crazy and sweep to zero back to normal values at random times with a check engine and sometimes an ABS light. will include a picture of the codes on ESA. looked all over the truck for wire issues and came up with nothing. No codes on Cat et and no codes on the Bendix program. cannot seem to make the truck do it at a standstill always while driving. Bad cesu possibly or what do you guys recommend to look at running out of ideas? Thanks! 2014 Peterbilt 389 with a cat 6nz
