Peugeot Expert II 1.6 9HU 2008 - Power loss, codes P0299, P0402 #

Posted by Liam Hall on December 12, 2011, 6:13 pm

Year of Manufacture *: 2008 '08
Engine Size and Code *: 1600 9HU
( Optional ) Scanner Used: SOLUS PRO
( Optional) Fault Codes: P0299,P0402

Hi

Looking for some help on this one, I have this van in with extreme loss of power, has no boost whatsoever.

I have checked for pipework leaks etc and have now come to a dead end.

After scanning For the codes I came up with the following definitions;

P0299 ; Turbo pressure electrovalve control - turbo too low compared with setting

and;

P0402 ; EGR regulation - air flow less than setting (150mg/stroke difference)

What I am asking is how do these work and how to test?

I have tested the supply voltage to both and that is good with KOEO.

I'm fed up of reading codes and guessing the parts, so would really appreciate some info on how to test with a multimeter etc.

I have access to AD, but no test info for these items are present.

Good old Autohasnodata.

Thanks in advance

Liam.

Have you tried looking for the info in other vehicles with the same engine codes? Normally works for me, E.g. Citreon Dispatch...

Have you visually checked the turbo?

Is the exhaust blocked?

Cheers

Hi Liam,

>>> I'm fed up of reading codes and guessing the parts, so would really appreciate some info on how to test with a multimeter etc.<<<

With all due respect it sounds like you are in need of some top up training.

I will try to help you but what tests have you carried out?

It sounds like the turbo is controlled via a modulating valve, have you made sure that there is a supply of vacuum being fed to the valve?

Can you carry out an actuator test the the modulating valve whilst having a Mityvac connected in line to see if the valve is working.

Have you looked into the EGR issue, removed the valve and checked it is in one piece, run an actuator test on it and seen it move?

It may pay you to look at the AMM and check its output. HTH

Come back with some test results and lets see where that leads us.

Many thanks for the replies - and I will be the first to admit I need some more training!

I have checked the modulator valve, carried out an actuator test and all working.

Vacuum is at the valve, and when started the wastegate is pulled shut, but the van produces no boost still.

Will only rev to approx 3500rpm.

I think it is the boost pressure sensor that is at fault, similar to the transit connects when they lose power.

I admit I have not taken the egr valve off yet, but have ran an actuator test and can hear it working.

I have tested the boost sensor with my mityvac and at approx 1bar vacuum i have 1v, according to the data I found on Vivid, this should be 2v.

Not entirely sure how to test the AMM, is a multimeter suitable?

Liam.

Are you sure the turbo isn't actually seized up.

Have you removed the outlet hose from the turbo to see if any boost is being generated or a leak in the intercooler circuit/pipe work. (if it has an intercooler)

I have checked the turbo, it spins when vehicle is ran, but there is a considerable amount of play in the spindle.

I have had the van at 3500rpm with the hose off and the impeller is spinning.

No hose leaks, checked with smoke.

Have just pulled the EGR valve from the vehicle, and ran an actuator test.

The valve only moves if i give it a nudge with my finger, and if i try to move it manually it feels like there is a dead/stiff spot at its rest position.

I have substituted the boost sensor from another vehicle and no change.

When looking in live data the required EGR % and repeat % values are the same and vary with engine revs, which lead me to beleive it was working correctly.

At £288.68 + VAT I really would like to be more sure!!

Has anyone else seen this?

Liam.

The EGR valve will only cause power / boost issues if failed open. can you temporally blank it or disconnected with it closed to see if things improve ?

It sound like it will need an EGR but not the main issue in my opinion.

After some more testing I have come to the conclusion that the turbo has failed, I now have white smoke, and if I persist in revving the van it will go beyond 3500rpm and a grating noise can be heard from the turbo.

I have had a chat to my factor and they say that the oil pump, sump pick up pipe and turbo feed pipe need to be stripped and made surgically clean.

Does anyone have any experience in the removal of the oil pump on these?
Are they akin to the VAG ones, sat in the sump?

Does anyone have any good hints or tips when doing these?

Thanks in advance

Liam Hall.

worth a froum search if this is the 1.6 engine

Have a look at this thread if it is same engine
