It’s all about the crankshaft sensor. After light start problems and sporadic dropouts the Volvo is read out and read out with the following errors: Crankshaft sensor signal faulty Crankshaft sensor no signal I didn’t battered for a long time and ordered a new sensor and installed, since I didn’t want to check the old one either, because the clutch had already been gneezgnadled by the workshop of my predecessor. I also changed the socket. after error memory delete and re-read: Crankshaft sensor no signal Both measured, the new and the old: old 298Ohm, new 286Ohm – should actually go. Now I came up with the idea to look at the supply line to the sensor and determined the following phenomenon: Resistance measurement on the cable: 15,2KOhm -“- with the ignition on it’s 11,5KOhm is normal?
