Another experience encountered (Error code P2BAB)

Post  HonG on Sat Nov 20, 2010 9:56 pm

Time to share another experience of mine with u guys again..

4 weeks ago... vehicle operating as per normal and suddenly malfunction light appears and blinking.. not sure what the problem is because can't feel anything wrong with the van except for the blinking light. Brought it to my mechanic (ah liu) and he diagnose my van via my ECU with his USB device and shows an error code "P2BAB" (NOx Exceedence - Incorrect EGR Flow). In case u guys don't know whats EGR, u can read it from here http://en.wikipedia.org/wiki/Exhaust_gas_recirculation or search for EGR in Wikipedia if the link fails. My mechanic suggested the EGR valve could be dirty but he also mentioned our ECU is very sensitive to some minor faults and so reset my ECU to try and see how it goes.

1 week later (which is during our Nov meetup), the light managed to stay un-lit until it buay tahan and blinks again when we were on the way to Kallang Bahru for makan. Van is still operating as normal. Brought the van back to wokshop and personally requested the mechanic to change my EO to my usual prefered brand and reset the ECU again. My last servicing was 3000kms ago and was using a new EO which I've never used before, and so I thought the EO might be the problem.

3 days later, the blinking light shows up again during work and spoilt my mood and morale for the whole day. But as I parked my van till the next morning, the blinking ight is gone again but reappears after a couple of hours. This happened again for the next 2 days whereby the light goes on/off by itself.

Brought it to workshop again and my mechanic suggested a way to troubleshoot to check where the problem lies. He disconnected the tube which transfered the recycled gas into the EGR valve, seals the vacuum of the EGR and reset my ECU again. Its is as simple to say that the EGR valve is still operating but prevented from doing any work. This time, he said if the malfuntion light manages to stay unlit, then the EGR valve itself is really malfunctioning and could need a replacement. But if the light blinks again, then the problem might lie elsewhere. It could be the valve controller which does the recycling into the EGR valve, causing high NOx which the EGR cannot handle.

Indeed the light blinks again after a few days again and immediately inform mechanic again. He went to did a check from other workshops/suppliers and got information that quite a number of Hiace owners had the similiar problem and quite a number had already changed/ordered the valve controller assembly to rectify the problem.

Returned to the workshop this morning and have it dismantle and this is the part which I've changed (look at how thick the carbon is surrounding the wall of the valve assembly) throttle body is washed too and coolant flushed.



hopefully the problem won't be back again.... Neutral

Have a very similar problem as honG. Wonder if honG can share with me how his problem was finally solved. What was the actual cause of the problem?

I bought this hiace in july 2010. The documents that came with this vehicle showed that it was bought from borneo motors. I'm wondering what has the problem got to do with where i bought the vehicle from, unless it is really a fake toyota hiace. Anyway, don't get me wrong, I'm not trying to be sarcastic. My intention is to get the problem solved in the most economical way, diy or otherwise. What i'm seeking is valuable information that can save me time and money. I'd appreciate it if you could provide me with some accurate information if you have any. Thks.

There a diff between a agent euro 4 3.0 n PI euro 4 3.0. PI have e DPF exhaust which alway giving problem while e agent hiace dun have this prob.
Most PI 08 euro 4 doesn't have e RPM meter .

alantan_74, as you can see another person is facing the same problem too. Would appreciate very much if u could share some experience or knowledge with regard to this problem. The problem I've experience is similar to that encountered by 'honG' above some 1and a half years ago. Very similar.

Bro, actually i not very experience but i juz know that PI euro 4 alway have this exhuast light problem and so far there is not total solution.E DPF is very problematic. Certain workshop only can delay e light from light up but still often is will happen. And also e exhuast valve.Endless problem

That y u can c from my other thread that i juz given up my deposit for a PI euro 4 and buy a euro 3 instead.
Unless Broneo Motor they willing to remap e ECU for you and u can take out e DPF, only that problem is solve totally.
If wana buy euro 4 buy those from broneo.Less problem then PI euro 4. At least broneo euro 4 dun have e DPF.
Is either exhuast DPF or exhuast valve...
If your is Broneo euro 4 or PI euro 3 then i dun know wat e problem cos so far these 2 model bo complain.

Both agent n PI HIACE runs on two different ECU. Hence it not same as abc. The engine build up is also different even though both is 1kD engine.
Not say it is fake or what..

But PI one is formulated as JDM spec... bM one is formulated as TDM spec.

Hi Hon,
Did you get the problems fix with the new EGR valve?
