Freelander 2, 2.2 td4 engine not starting

[sepistar]

Guys,
have an freelander 2.2 engine year 2008,which has stalled while driving and since never started again.
As recorded error pcm has P0698-16 Sensor reference voltage C - Circuit low
Have change crank and cam sensors but problem remain,it crank and never start.
On start pilot it starts but stops when no more spraying.
Btw try other pcm too,nothing changed.
In live data when it crank has 280 bar pressure and 2xx rpm,but simply it not fired.
Maybe someone has same situation?

Check timing

[autoden]

Reference voltage? Did you check it? The ref 5v must be on most sensor,s. Test at ecu first. One could be pulling the v down. Disconnect all, then replace one at a time, checking all the time to check.

[Black dog]

Disconnect dpf temp sensors.

ON TOPIC:-

unbolt lumpy stick sensor, leave in free air, crank few seconds, should instantly log lumpy stick sensor fault.

not sure on that EXCACT car, unplug egr valve if electric

[sepistar]

Disconnected all sensors including dpf and egr,reconnected one by one,
check dtc after each sensor disconnect/reconnect nothing bring it back to life.
Ground to ecu are ok.
Somebody has ecu full pinout?

ON TOPIC:-

3 pin plug on fuel filter?

OFF TOPIC:-

had ford focus and where injectors were twisted they rubbed

That is a power suplly for some sensors , ignition on and measure 5 volt on camshaft sensor , dpf sensor .check in live data voltages .also could be power supply for injectors , edc16 has live data with that voltage around 80 volts . Did you check all fuses and edc powers supply ?

Check sensor supply should be 5Volts.....Had one a few months back ended up renewing the ECM as the supply to sensor from ECM was missing ...cant remember exact code but check supply

[sepistar]

ecu already change,problem remains.
some of the sensors have 5v.

[ecufix]

Does it start if you spray some quick start into inlet?

Member stated yes in first post "start pilot, stop spraying"

so, points to the loom has chaffed.

OFF TOPIC:-

ford transit 2002 ish, get fault "pump watch dawg"
basically wiring loom next to pump covered in oil and insulation fails

did you get to the bottom of this problem as i have the very same issue

[Meat-Head]

On topic:-

a fuel injected engine MUST have speed and load.
so start with map/maf sensor.

live data says?

[smokinjoe]

map/maf,egr,injectors,frp all disconnected,no change,would someone be able to help with wiring diagram and tell me which sensors are connected to circuit c

[Meat-Head]

Throttle pedal? And/or unplug ecu see if ground on pin ??? Of sensor
google images the sensor hope pin out

glowworm controller?

doubt it but if easy dynamo

if bmw try looking for e46 bmw diagramming?

[smokinjoe]

thanks i will try your suggestions tomorrow,its not bmw but ford based with psa engine,first thing that came to mind was the egr as i recall them giving this problem on the 2.0 mondeos but not the case with this one.

[Dunker]

Very unusual to have an ECU to have more than 3 separate 5v reference outputs regardless of how many 5v fed sensors are on the engine. Most are shared 5v feeds. Back probe every sensor and look for a low 5v feed. Had a transit the other week and I could only find a low voltage (3.4v) feeding one of the accelerator pedal tracks. Turned out it was position sensor on turbo vane diaphragm that was pulling it low. Same sort of fault code. If you haven't got a back probe disconnect sensors one at a time till the 5v reference fault code clears. If it doesn't then it's the loom if the ECU has been swapped already.

[radiosolutions]

Check engine earth has not broken. Also agree with earlier post. Timing issue

[sepistar]

Have never found what the issue was
They took the car to Land Rover dealer
Guy from dealer call me and ask what i have done so far,
After some time owner calling me and say that the dealer attempt to repair was unsuccessful.

[smokinjoe]

Starting to see this is a bigger problem than just engine management as yesterday instrument was totally dead,no communication, and today it works again but i cannot remove key,bcm had crash input flagged although it did erase with diag, will keep all updated ,at the moment I'm getting a feeling of a bad bcm or multiplug connection somewhere as it appears to be quite damp at the back of the dash but bcm itself is clean and dry. I have checked multiplugs at the back of the glovebox which are good.

VAGUE MODE

we had a Landrover something wrong the internal fusebox (piece of plastic with fuses)
had gone verdis gris

VAGUE MODE OFF

[smokinjoe]

Problem solved, dead cluster fault was the cluster itself with same issues as the ford focus and the no start was due to the wiring loom damaged at the back of the block leading to ckp and turbo actuator,it had rubbed through and melted to the block.
Happy Christmas [emoji319] to all.

Good hopefully you charged enough for two xmas trees this year and two for every month until next xmas
