I have a VOLVO FH12,420 Year 1996, with fault codes and the Engine run well on the lower revs -600 up to 1300, and from 1400 upwards starts misfiring,tried to disconnect CPS( Crankshaft Position Sensor), makes a difference when disconnected the engine retain high power! (a little smokey on pipe). It is something to do with PDE Unit Injector nozzle ? somebody can help and assist me to get VOLVO FAULT CODE GUIDE for the type D12a model? Thanks From land of KILIMANJARO!
Pablo will be round soon. Search the forum for a thread about Fault codes in the garage section. BTW I used to have a business in Mwanza.
Thanks, King Q ! Did you learn sukuma language and culture? Did you visit Bujora? Tried to search Fault Code Web Links but there's no codes for VOLVO FH12a 420. Waiting for PABLO to assist me to rectify this fault! Thanks for your attention KING Q!
26-27 Crank and cam sensors sygnal is not OK, may be cam shaft is installed wrong, may be damaged sensor ore flightwheel 23 ECT sensor signal low 41 and 46 are info codes, not fault codes
Really D12A is the first D12 engine, but I can see it in early FH and FM and in WG that keep running here
Pablo-UA ! Masterpiece of 90'S, still roar in tropical climate of AFRICA! Imagine the OFF-ROADS of AFRICA! King Q, I understand he knows, and has the experience of what am talking about.
Thanks Pablo-UA! First thing tomorrow, I will start cross checking what you said. Please can you clarify code 41 and 46 which info the system is sending or has been stored or received ?
No , unfortunately I have never made it to TZ. Had some other guys running the business. I'm sure I will make it out there some time.
