hi all,
Fuel consumption of my JTD a bit high lately. I did run a diagnostic using Multiecuscan and found the P0404 error: Invalid EGR signal. I did a clean all soot inside and it seems the valve spring is all good.
Put it back and did a test run with rpm >3000 but I still got the P0404 error code. Then using multiecuscan again to check the EGR solenoid valve if working or not. Unfortunately, I don't hear any clicking/whatever sound from the solenoid.
Checked the wiring harness with a multimeter to check the circuit and seems no continuity :bang:
Has anyone got electrical diagram of injection ecu to EGR?
