Engine: D52447: Loss of power (read on VIDA)

[GScottHosking]

Hello all, my 2010 auto D5 XC90 has a loss of power when going up hill. If I put my foot to the floor the car doesn't get up and go, it simply revs and continues as it was before I gave it WOT.
I have VIDA and have been given the following issues;

CCM 0040 air quality sensor internal fault
ECM 1507 turbo control too low pressure
ECM 2A20 Particulate trap - signal too low
ECM 500F air condition faulty signal

I drove the car home this evening and it was fine, pretty pokey in fact (for what it is).

Any ideas folks?

Thanks

ecm1507 and ecm 2a20 are the ones you need to concentrate on use vida as a diagnostic not just a code reader bring up the ecm in vehicle communications and read the ecm to drill down further in to your faults.

Thanks for the feedback, you are quite right, codes alone are a touch useless.

With that in mind, I did some data logging today over a short drive.

I monitored the following;

pressure sensor particulate, it remained at 0 hpa for the duration of the journey, occasionally it would hit 5 hpa, I'm hoping that means the sensor is shot?

Boost pressure actuator, this looked to be ok, I got readings that appeared to be sensible based on the road speed etc.

Intake manifold pressure and also atmospheric pressure, atmospheric remained constant while manifold pressure appeared to rise and fall with engine speed.

Would anyone happen to know what else I should be monitoring in order to hunt this 8ssue down, I would rather not replace the entire intake system on the off chance I get the right part.

Thanks

if you double click on the indicated faults this should bring up possible cause and possible remedy

It does, unfortunately it tells you it could be a number of things and the system isn't clever enough to combine all the info to help eliminate issues.

I'm hoping someone else has had a similar issue and resolved it.
