Symptoms:

-Engine cranks normaly with no engine warning lamps
-compression felt out of exhaust ( engine is overhauled by the book)
- no ignition, tested with old plug on one of the leads and with a stroboscope lamp.
-fuel pressure all the way to the injectors, first tested disconnecting the bayonet spraying my t-shirt and by depressing the pressure test connection with the ble cap.
- Fault seeking i discovered that the fwd mounted VIS motor was hot, unscrewed motor housing an the motor started running, the heat came from to much resistance from the flappervalve? Inside the inlet manifold. Tried by hand and must have been to hard for this small motor. Having the vis motor out of the manifold, and electrically connected, it starts running when i turn ignition on and just keeps on running for about 5 minutes before it stops.
-Revcounter reacts when cranking.

Fault codes observed using a Foxwell scanner ( havn’t got the TOAF working properly yet)
P0340
P1477
P1473
P0155
P0152
Had to tell my scanner this was a Freelander 1 V6 to get some codes

Now the big question: Do i have a suspect ECU, giving these symptoms?
And thanks to you all for tips
Check this one: https://www.fixdapp.com/blog/p0340-code <-- Camshaft sensor. I might have one laying around...
P1477 seems to be related to the crankshaft sensor. The other ones seems to be VIS and O2 sensor related.

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.

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.

Personally, I would buy replacements but it's up to you.

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

Hi There!

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

"New" sensor Ivar or used? Genuine MGR or aftermarket?
Did you have to buy a wiring adaptor from "new" sensor to the car's loom?

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.

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👍
