Looking at your Live Data, your MAP Pressure is a bit higher than I would expect although I don't have figures for your Engine.

I don't know if the  quoted Throttle position is above the normal "Closed" Resting Point, which is slightly open, if it is then that would explain the higher than expected MAP.

It may be that the Throttle is opening a bit more because the car is trying to keep running because of whatever the fault is.  

Hi @Tizer 

I have no idea if this is of any use?? But the below link is the live data of my partners car. Which is also a MK 6 but a 54 plate instead of a 53. 

 

Any ideas?

The MAP is what I expect it to be, almost half of what your one is but the Throttle Position is about the same, so if the Throttle Sensor is reporting its position correctly it would rule out what I said earlier.

A leak in the Inlet Manifold after the MAP or some other means of introducing Air such as a Breather, EGR, Idle Bypass etc would give a higher than expected MAP reading.

I had a split in the breather, Which I changed and I ran a smoke test and there was no was no smoke escaping expect near the fan entry point if that makes sense? Well I have a ford scan turning up tomorrow  I am hoping that might highlight more things. Gave the MAP sensor a clean, and as I was saying earlier the P0341 code came up and may flag every now and then when putting the engine under revs. 

Was wondering if the breather vaule in the engine is buggered and instead of only allowing one way is is allowing two ways?

It could be if the Breather is after the MAP Sensor.

If a Petrol car was not Throttled then the MAP would read around 100kPa, at Idle the Throttle is almost closed so you should have around 30 kPa, your one is nearer 60 kPa, which would be fine if the Throttle was a long way open, so it could be some type of Air Leak that is causing the high reading.

Breather is just before the MAP sensor, As I say I ran a smoke test and no leaks. Breather pipe is sealed and all  pipes around the system are not leaking. Only leaks are around the air box where the pipe meet the box if you know what I mean? 

@Tizer

 

 

3 is the Breather pipe the clip looking thing just above it is the Map. The other side of the breather hose is on the other side of the Map at the manifold which is a valve that could be running both ways? Which I guess would be why no smoke leaking on the test? 

 

Looking at your last post yes the breather pipe is after the TB

Oops, sorry I meant to say "If the Breather Pipe is after the Throttle Body", not the MAP Sensor.

So anything that lets Air into the Inlet Manifold after the Throttle would give a higher than expected Map reading.

I'm not that familiar with the Breathing system on that Engine but if it was only meant to give a slight bleed now and again and it is giving more than this then that could account for the high reading.

Try clamping it closed and observe if the MAP reading reduces and if the car runs better.

So it goes TB - Breather hose start - Map sensor - breather hose end - valve in to manifold. 

 

Could this explain why it will not go about 3k revs or 30mph? And after getting it to this point the car dies and is takes a lot of holding and easing off for it to then hold the revs. If this was the problem would the system be demanding fuel not dropping it to -25% short and long term fuel trim.

It is difficult to say what the Electronics will do if something mechanical is not doing what it is supposed to do. If you Clamp it closed you should get an answer.

Hi @TomsFocus @Tizer @unofix 

 

So I got the scanner turn up. Just ran it. Do not think it has highlighted anything that the other scanner highlighted. 

 

Here are photos and logs. Any ideas? 

 

 

 

 

Have logs from fist putting it in. 

run scan.txt

Running 

Forscan running.txt

Under rev

under rev.txt

 

Any ideas ladies and gentlemen

 

Also ran a scan with the one I already have and this was the outcome

It's showing the cam sensor fault is still a current fault.  So there is a definite issue there, not just a faulty sensor.  That's the one that needs sorting.

 

Find the fault with the Cam Sensor, and worry about other faults later.

 

I agree with what the guys have said, very little in an Engine works in isolation so if there is a definite fault in one thing it can throw up spurious readings in other things that might not be faults in themselves but caused by another thing that is faulty but work correctly when the main fault is fixed.

So this is the only live data testing I can do, Talking to Tom I know I now only have three options, 

Get a mechanic to look making sure the belt has not jumped. 

Get a auto election to check the Cam and knock sensor wiring 

Send of the ECU to be tested. 

Tried to upload the live data I did run but would not allow me to upload to youtube, 

So I was just looking on youtube and I found this, Seems simple enough to at least find the problem, Thought I would post it here in case anyone else was having the same sort of problem.
