P1477 seems to be related to the crankshaft sensor. The other ones seems to be VIS and O2 sensor related. Last edited by beinet1; 21st November 2020 at 06:23.. |

No.
P0340 = camshaft position sensor circuit malfunction, no signal. Without this, the engine won't start. Initially, check the electrical connections are sound as you have had the engine in pieces. Some members have had success placing the sensor in the fridge for a period (a search should provide details). P0152 & P0155 = oxygen sensor 1, bank 2 (RH bank at exhaust manifold). These wouldn't prevent starting but need your attention. Again, check connections. P1473 & P1477 relate to VIS actuator "2" which you know about. Simon

Thanks for this info. I have the ECU out now for visual inspection with the battery disconnected, all pins looks good. will put it in again and do some more testing on the sensors, and Einar, if you have a sensor you can lend me, i would be very happy

With regard to the VIS motor. It sounds like the inlet manifold butterfly that it connects to is sticking (a common fault). Take the butterfly out and ease it by removing whatever is making it stick (carbon or plastic). You may have to replace the VIS motor or open it up and reset it to the correct position.

Replied to your PM regarding Stocktake VIS motors. My daughter's car had a main ECU fault which baffled me https://the75andztclub.co.uk/forum/s...d.php?t=286990 and took a long time to fix. Most puzzling for me were the VIS faults despite knowing the motors were 100%. If you review May's posts on the Swedish FB group you might find a post where she described the fault codes listed by her garage, some of them sound familiar. Regards |

I have located the crankshaft sensor I have in spare, but did not found the camshaft sensor. I will check out if I can locate it and would happily borrow you them against the postage I also have a VIS tester which you can borrow, but that did not seems like the biggest issue at the moment. |

Got the TOAF up and running, and this is what the fault codes look like now. The cam sensor recieves 5 V from the ECU, tried with new sensor also. Still won’t start |

Camshaft position sensor

Did you have to buy a wiring adaptor from "new" sensor to the car's loom? Simon

Would have thought you'd have received the Stocktake motors by now as they were sent on the 23rd as a letter but you haven't replied to either my mail or PM?
Would be interesting to see a Toaf scan once you've replaced the motors. If you recall my daughter's V6 reported VIS errors even though I knew them to be good, ended up replacing the main ECU. Regards |

Found the solution at last. May’s old engine started. And the problem was quite stupid😂😂 when i got the vehicle all the engine electrics where disconnected, assembling all of it i have switched the connectors between thottle position and cam sensor??? They are alike and close to oneother. The idea of this was when i started measuring voltage on the connector leads. The lead i thought was for the cam sensor had two pins with constant 5V and one earth. The cam sensor needs power on two leads and the middle one is for output to the ECM. This was quite confusing, and my thoughts was a corrupt ECM. Remembering there was other 3 pin connectors in the area, i found they are alike😂😂witch i am not used to with Land Rovers, usually foolproof. The engine started at once, only a bit fussy without the VIS motors connected. These, Mike are helping me with👍
