MAP sensor location and error P006D, P0101 and P0113

Read again my post which you quoted then your's cos it seems you mixed up things... as about diagnosing such sensors with multimeter i can't tell more than i already said about the MAF
 
so the latest is this. i cleared all the errors and the car starts etc and as before i get restricted performance. No errors. i then disconnected the MAP sensor and immediately get an error P0108 " Manifold Absolute Pressure / Barometric Pressure Circuit High"
The car still started and is still in restricted performance mode. no change to its performance

If that sensor is fubar it's normal to not be much performance improvement with it unplugged, i told you that the MAP's default is not like for MAF... unfortunately the diagnostic protocol for this sensor is not very complex as this code can have various reasons and it's the same for short to power or open circuit which is silly, IMO untill you dont rule out 100% that sensor with a new one the whole thing is just a guessing game as long as you dont have a complex diagnostic tool which can record live data to folow the LR diagnostic procedure for it... here's from the Ingenium 2.0 diesel DTC index

so currently i can still drive the car. when i start it, i have about 20 seconds where i can revv it fully - but then i get the restricted performance error and it caps off the revvs at 3100. i can drive it and its slow but eventually gets to 3100 revs which equates to about 65 mph but i can feeel it trying to go faster - it is the computer stopping it rather than a mechanical thing. very frustrating. is there any way to just globaly reset the computer? i cleared the errors and there are now no errors showing
 
so i took it out for a sping there and it goes slow and sluggish but gets to 83 MPH and sounds fine. i got a new error code though today - "P24C2 - Manufacturer Control"

If the faults are present, there's nothing to reset, as they're still logging.

I'm curious as to why you need to rev it to over 3k? I seldom take my FL2 over 3k, normally the RPM stays below 2k on mine, 70 MPH is 1950 RPM.

Revving the enginium engine isn't good, as its known to suffer oil dilution, so catastrophic engine failure isn't far away if high RPMs are used.

It sounds like it needs to go to a diesel specialist to cure the issues, but if the DPF is clogged, it needs cleaning or replacing, or the MAP and MAF will be getting false signals as the engine can't breathe.

But how can you confirm it as failed or not without a dedicated diag tool?

my question was rhetorical as i'm sure you can 100% rule out the sensor without any diag tool by replacing it with a new one... and that's the only way as long you can't carry out te exact LR diagnostic procedure. No miracle will fix the sensor if it's fubar and untill it was not ruled out you can keep waiting for that miracle IMO... and even if it's not the sensor at least you are one step forward and you have a spare... don't think that these sensors are for a lifetime

No - once the errors are reset they go away and stay away but the engine is still sluggish. I dont "need" to rev it over 3k. It revs to 5k before the "limiter" comes on then it revs to 3k. it gets to 83 MPH but very slowly especially the first 30-40 mph. uphill is chronic, downhill isnt too bad

The point is - its the computer thats limiting the engine - not a physical engine fault - the engine runs fine untilt he computer limits it

Now since the last reset i am getting 2x new errors:
P0101 Manifiole Absolute Pressure / Barometric Pressure Circuit HIgh
and
P24C2 Manufacturer Control

Are you sure it's not P0108? cos P0101 is about something else but if it's about manifold absolute pressure you are back to square one as long as the MAP sensor is not 100% ruled out :rolleyes:

yeah good shout its a typo was 0108. took the MAP out again and its clean as a whistle at the moment

So are you saying that the codes don't log until you take it up to the limiter, after which point the RPMs are cut to 3k?

Just a few things to note, which you might not be aware of. The 5100 RPM limiter isn't a target engine speed, it's an absolute maximum speed, and shouldn't be reached except under extreme circumstances. This engine delivers full torque (of 500Nm) at just 1500 RPM, and peak power of 237 BHP at 4k RPM, so there's absolutely no need or benefit to revving beyond that point. It's a diesel which isn't designed to work like that. I believe the ECM could be putting it in limited performance mode, possibly to protect the engine from an abnormal drive cycle.

As for the fault.
I suspect there's an issue with the DPF as already suggested. At stupid high RPMs, it's upsetting the whole induction circuit, hence the random induction codes.

My advice would be have the DPF cleaned or replaced, or buy a vehicle that's actually designed to be driven like a sports car.
