Hi all, this Peugeot 406 of year 2000 intermittently and without warning cuts out when driving,(last time was at 70 mph) can be days apart, and will restart ok according to the owner. No fault code numbers with the Launch but got codes as follows: 1"Intermittent fault. Cooling function incorporated into ECU Coherence between fan unit speed and "reference value 2"intermittent fault. crankshaft-camshaft synchronising. Engine speed signal variation sudden" 3 "Intermittent fault. Fuel pressure regulator stop requested but regulator still active" 4"intermittent fault. High pressure diesel monitoring. High pressure diesel regulator blocked"
Deleted these codes easily apart from number 3 which kept recurring, so checked resitance of fuel pressure control solenoid which was good at 3 ohms as was the feed voltage to the 2 pin plug, however the car also does not always stop instantly when ignition is turned off, sometimes runs for about 4 or 5 seconds so am wondering if the stop solenoid is also part of this unit? I also wondered if this unit can cause intermittent cutting out. Crankshaft sensor resistace was good at 400 ohms and live data all seemed good at that time. I drove about 6 miles with no problem, performance was excellent(mileage is about 186 thousand) , thanks for any help, Jim.
