the 5v comes from the ecu, so you need to trace back through the loom and find where the problem is, the 5v out is shared with a few other sensors so its worth checking those as well, there are some splices in the loom where one larger wire splits to various components, its likely one of these is at fault.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

The 5V comes directly from the ECU in my case 2V, crank sensor is number 57, 3th pin is earth/ screened/, there is no splices in the loom |

Yes, i have permanent 12V on pins 11,2,8,15,ignition ON - 12V on 14th. If i reconnect the double relay the first start is excellent. On the next i have issue, the relay is blocked from ECU and the engine starts hard, but always 2V on the sensor |
