Engine loses power - P2008 Error Code

[D22marshall]

No chip no exhaust everything standard, I have the egr vacuume line to the egr blocked so it is not operating at all. Maf has been cleaned and no cracked. It is an 05 model so the egr blocked off is not causing an engine light.
Thanks dean

[D22marshall]

Next idea was to clean the inlet manifold and egr??

Have you tried unblocking the vacuum and putting it back to normal? This can bring the engine light on.

[mattwhite]

He blocked it after the fault started. The code basically sets because the maf isn't reading as much air as the ecu thinks the motor should use. So if you've already cleaned the maf then yeah, I'd clean the inlet. It's good maintenance anyway after 8 years. And it is feasible it's setting the code. If it fixes it report back so others know in the future.

[D22marshall]

Ok I have it booked in early next year to get cleaned out then we will see what happens next, will report back but any other ideas very welcome

[Talktheroo]

This is the best way to deal with this problem.
The Provent 200.





Okay, this is fitted in a 120 Prado, but you get the picture.
Just recently, I pulled about 400ml of oil residue out of this unit.
The filter is on it's second time around.
The Roo.

[D22marshall]

Roo great someone has got onto something will look into this can you give me a quick run down on this and why my truck was doing what it was? Regards dean

[D22marshall]

Put some injector cleaner in and re connected the egr and the car has been running perfect

Been a while since I've been on here and an update to my situation. Took my local Toyota a while to find out what was going on...they thought it was the EGR that was gone so they replaced that, which is all built into the intake manifold so that was all changed out under warranty. They finally found the problem in late May/early June. The sleeve in which the wastegate actuator feeds out from the exhaust housing on the turbo was leaking out soot so the turbo wasn't getting full boost. So when the engine was under high throttle input, the fuel was put in at the correct rate but because the boost was lacking, it would put it into limp mode to protect itself. Managed to get a new turbo out of extra care. Took some fighting

I have a 2006 hilux auto D4D (280 000km) and I have been trying to work out for 12 months why my hilux goes into limp mode when I'm driving up hill around 100km/hr. Specifically it seems to happen just as I take my foot off the accelerator. It has a steinbauer chip with boost control and the owner from steinbauer came out this week to Brisbane to specifically tune it for my ute thinking that may have been the cause however it's not. We unplugged it and still goes into limp mode. Exceptional service from steinbauer. I also have a 3 inch exhaust with high flow cat from Taipan. They have been super helpful as well. The Steinbauer head technician came with me to my dealership to explain to them it has nothing to do their chip or the exhaust.

The fault code is P2008. Manifold intake.

I passed on the solution above to them today so I'm hoping like hell it will fix it.

Would welcome any ideas or solutions for those who know of this problem.

Clean your maf sensor make sure it is spotless.

Toyota didnt bother cleaning it - just replaced it - $500!
Then said all was fixed. Took it for a quick drive down the road - P2008 intake runner manifold cicruit comes up.

"only the best mechanics with epertise in the are worked on your hilux sir......................"

Through hours / days of trawling internet threads the P2008 code appears when someone has a 3inch pipe fitted and the ECU can not simply comprehend the values. toyota can not fix this.

[mattwhite]

Read it on the net, must be true.

Of all the people on here with big, chopped up exhausts or even stacks I don't beleive it's the exhaust.

Whilst I almost was convinced of the exhaust theory too, there any many reported instances of the hilux having this fault code on completely unmodified vehicles. That being said... If Toyota explore every avenue and it's still unresolved I'll be ripping out the exhaust to finally put that theory to the test. But at the moment I don't wanna burn that cash I've invested on the taipan exhaust.

It is like the old saying

Well let's hope that isn't the case. After all, people who are not mechanically minded like myself trust people who sell us the accessories to improve our vehicles and not cause problems. Fingers crossed I don't get to the point of ripping out the exhaust.

[boxhead55]

It is legal to sell anything you like!

A salesperson is always going to tell you what you want to here.

It is when you get investigated shit goes pare shaped.

Like exhausts without cats, suspension lifts without the correct bpv adjustments so you have rear brakes,
hid head light globe replacements,
musical air horns,
t 5 window tinting just to name a few.

Also nowhere not the toyota repair information is stuff like

( if after market exhaust is fitted reading will be-----)
or
(if performance chip is fitted xxx--- sensors will be out of speck!)

I know a lot of toyota dealers will not diagnose problems if a chip is fitted. Some fill out the modified vehicle information sheet and
send it off to toyota Australia.

Then warranty
Really does become a problem.

So I guess what I am trying to say is buyer beware.

Hey box head

If Toyota had the knowledge I'm sure they'd be charging everyone round the world with p2008 issues to fix them instead of having there. ' master technicians' to replace expensive components then stand around looking like idiots when it doesn't work

I see Toyota as no better than the salesman selling the 3 " pipes.

Have you ever suggested a customer remove his 3" to get rid of the p2008 or is it straight to new map and mad sensor , new intake manifold if they are out of warranty....

[boxhead55]

No I haven't and I have been in the game so long I have many known good sensors for my diagnosis so the customers does to have to pay for the diagnosis process( well not with me)

Have you check and cleaned your MAP filter? made sure there are no tiny cracks ?
link viewtopic.php?f=13&t=20711&start=20
Have you blocked or fitted a 10mm hole blocking plate to your egr?

[LUX666]

All,

Not sure if these have been posted before, if they have my apologies, but here is the list of fault codes for the D4-D engine management system.

Now please remember that while these are the diagnostic codes, it doesn't mean that the particular sensor is at fault, the fault could be generated by a bad electrical connection in that part of the loom.

Hope this helps.

I will repeat what I stated earlier, the problem seem to be in pre 2009 vehicles and predominately in the Auto's, but you will see No codes here for the Auto transmission, yet Toyota have a list of codes for the transmission. Also in 2009 Toyota released an updated flash program for the 4 speed Auto's, the head mechanic at the dealer I use told me that if a customer comes in with the problem of the vehicle going into limp mode, they will flash it with the new software, if not they won't upgrade it, only what I've been told.

Hopefully this problem may be solved with the release of the new 5 speed Auto, we can only wait and see.

Hope this helps in some way.

Cheers

John

Thanks John. Interestingly I found out yesterday they have found a fault in the electrical connection. They are going to give me more specific details on Tuesday
