New EGR valve fitted in attempt to fix problem - no change.
Need advice please, this sounds like an electrical fault somewhere, but where ?
Question - the big plug that plugs into the ABS pump next to the front bumper under the cab - do these wires have any connection with the above fault codes ?
Does the ABS pump have anything to do with controlling the above fault codes ? Could that be faulty ?
Is there an earth wire that may be off or broken that is connected to the fault codes and where would I find it ?
She's a great truck but life was so much simpler in the old days !
ANY HELP - GREATLY APPRECIATED.
