Moin moin, our Volvo just went out a few days ago and can’t be done any more. I switched the camshaft sensor for the first time. One time for one of our other 850 with 2.5 liters and one new one. The ignition cables were hit, so I changed them for the one from the other Volvo (they’re just new). I can only measure the ignition chairs between plus and minus. Between the ignition connection (the big one) and minus, mass and minus. plus (measured for safety) I can only measure an infinite large resistance. So I also exchanged the fuses for the ones from the other 850. I measured them before, everything ok. However, the one from the other had this 4-pin plug, which is connected again with two cables to the fuses. I removed the cables and connected the connectors from the vehicle there. Nevertheless, no ignition spark. The fuses get 11,xx Volt voltage, the old fusespu Hle didn’t have a 4-pin plug, but simply had two connectors (plus and minus). The vehicle has no immobilizer unlocked with this pen. I don’t know how exactly the ignition is “controlled” by the vehicle if the chair has only two connectors. I would be grateful for any help because I don’t want to buy ten pieces on suspicion and the error then disappears without knowing what it was.
