2016 SR5 high Idle DPF?

[dervdave]

the mazda DFP has an extra injector in the exhaust that super heats the exhaust system and burns it off, doesn't affect idle speed, but you can tell because the i-stop is disabled and there's a deeper hollow exhaust note when it's doing it.

Do the hiluxes do it that way?

Well I've logged a ticket with Toyota Australia as the dealer is telling me that I need to drive around 65km/h for half an hour regularly. Living in a country town, I am either below 60 or at highway speed of 110. The dealer has told me that driving 100-110 is generating more carbon than the dpf can burn off. It's getting to the point where the vehicle isn't fit for the purpose it was sold as. Who would have thought you need to live in an urban area to own a hilux 4x4.

Hi guys,
My sr5 auto hilux did a regeneration the other day. The idle was slightly higher and the engine just sounded a little different. There was no light on the dash to tell me but when I put my had behind the exhaust pipe it was roasting and the exhaust was jetting out. The only reason I checked was that it was blowing leaves away from the back of the car. It was so hot that when I held a leaf up to it curled up and started to smoke

I do a 150km round trip on the highway to and from work everyday so I was surprised that it needed a regeneration.

It makes me think that they must regenerate all the time and that if a light came on every time then people would be constantly back to the dealer thinking that something must be wrong

This worries me, I was bogged in mud upto the side steps the other day.. It was trying to re-gen and making quite a burning smell. Motor has to run to use the winch so had no choice. If i was bogged near something flammable, that would not be good. I think the vehicles need some sort of user input that can temporarily disable the process, should you be in a location not safe to do so. I regularly drive through spinifex much teller than the hilux, I do not want it trying to regen then.

I've done 13,000km's so far and I haven't noticed a burnoff yet, I've done a few long trips and when towing the boat (solid 3t ) it probably cleans everything out !!
the Duramax Silverado I used to have I could hear it doing it occasionally and the fuel flow would be 50% higher for that time !! I only once had that go into limp mode for the DPF and a 30km drive sorted it out. (should have done a delete) I reckon when a delete comes out for the Hilux that will be the way to go and that with a tune and an EGR block off should unleash some ponies, might get to half the NM that the Silverado had !!

out of interest, is yours a manual or auto?

1 - injector, 2 - glow plug, 3 - air flow meter, 4 - turbocharger, 5 - exhaust fuel addition injector, 6 - oxidation catalyst (DOC), 7 - differential pressure sensor, 8 - diesel particulate filter (DPF), 9 - exhaust gas temperature sensor 1, 10 - exhaust gas temperature sensor 2, 11 - exhaust gas temperature sensor 3, 12 - glow plug controller, 13 - coolant temperature sensor, 14 - ECM, 15 - combination meter, 16 - air fuel ratio sensor, 17 - CAN bus (V) . /

DPF passive regeneration can be performed by itself under the condition of exhaust gases high temperature. However, over time the amount of soot in the filter is increased and its capacity is reduced which requires active regeneration. The control unit determines clogging of the filter by analysis of driving conditions, and activates injectors, the exhaust injector, glow plugs and controls the engine speed. The DPF material temperature increases and soot particles burn out.
But if driving conditions do not allow to perform active regeneration automatically for a long time, soot accumulation may exceed the specified limits, so then the ECU illuminates DPF warning lamp, offering the driver to move at a constant speed above 60 km/h to perform active regeneration. When the maximum level of soot accumulation exceeded the warning lamp flashes, offering the driver to go to the workshop to perform regeneration in the manual mode. Finally, in order to avoid damage to the DPF, ECU activates fail-safe mode with limited engine power output.
HiLux has optional switch of manual mode regeneration.

Sounds like if you dont take heed of the DPF light, and the soot quantity exceeds allowable amount, your hilux will go into limp mode and you'll have to take it to the dealer for a manual regeneration.

will have to find out what the manual regeneration process involves.

Very interesting thread. I was seriously thinking of upgrading my 2012 D4D but will wait a while longer to see the outcome of all this dpf stuff. The fact that your exhaust is clogging up from the word go until a burn is initiated which pumps more fuel into the exhaust must be great for fuel economy.

When a Detroit or Cummins needs a regen because the driver hasn't allowed or performed a burn off, a forced regen is performed...it's only a matter or flicking a sequence of buttons etc and it'll sit there for 30-40min and performs a 'forced regen'. Then she's good to go. I would imagine it's similar. We just need to speak with the right people to work out the right process (the roo) :):)
My manual which is used for both highway and city use hardly ever regens. Maybe once every three weeks for 10min. Done 10,000km,

it's an auto

I have just taken delivery of my new SR5 today and have done 360km and have already noticed a a burn off. Admittedly the first 120km was around the city of Brisbane averaging below 50km/hr. Got 600km highway driving tomorrow so hopefully it won't need another one for a while after that.

[heavymental]

How noticeable is the regen process?? I'm due for the 10,000 service and can't say i've noticed it.

i do get a smell of burning plastic/ rubber every now and then haha but that could be something different.

[Ryan1kd]

I've just clocked 10,000km and would say it's never bothered me at all. Would have noticed it about 10times maybe in the last 5 months. With all kinds of driving.

For me it's quite noticeable.. I go low range almost every day down in boggy sand - you're letting out the clutch at 12-1300 rpm when it's regenerating.. Frustrating after driving 150 odd kms at 110km/h, then trying to reverse the trailer down a long alley and it's trying to make it's mind up whether it's idling high or not while i'm going up the incline

I have the same problem with the SR Hilux, it will quite often start reving to 1200 revs when I pull up after driving somewhere and it doesn't matter if it is a short trip or a long trip. For me it has gone down to reving normal once after 5mins and other times I have become inpatient and just turned it off. Going for its 6 month service next week. I wish there was more info in the driving manual about it. No lights have come up on the dash when it does it. Frustrating

Dpf is the elephant in the room for many manufacturers. They're quietly introduced without anyone really noticing , yet are an expensive and injury prone system in any vehicle. It's there to meet the increasingly high emissions restrictions.

Google dpf problems and you'll see it's a multi thousand dollar grenade in most vehicles. Usually after warranty has expired.

It's a negative in the diesel viability column.

Mazda for example didn't bother entering the US market at all with their diesel 6 (shame , the twin turbo diesel is awesome donk) because their emissions regs on nox pariculate are just too high.

Ironically they are much less caring about c02 and drive big petrol guzzlers. Diesel pariculate is cancerous though hence they're stricter on it.

Other options are urea blue and other expensive treatment methods

got the hilux back home 400kms later, start it up next morning - high idle again. It wouldn't be so bad if it had something simple on the dash just let you know what it was doing, but for me, there is no way of knowing. I live in a small country town, I'm either doing 110 on the highway or plodding around in town. There is no need to ever stop/start, the closest roadhouse is 220kms away so I don't realise it is doing it until I pull in.

I know it's not a big issue at the moment, I am just worried about the threat of limp mode, that would be crippling for me given I could be 200kms from any traffic or reception at the time. I do carry an epirb, towing costs $4.50/km up here, trying to avoid that

Have the same problem - hit at 250ks! Do a lot of short trips around farm and town, so can't see it completing its cycle too often.....

[Ryan1kd]

If it starts its cycle...just leave it running for 10-15minutes to let it complete it. It'll thank you for it.

This is part of the problem I have.. Mine is not completing the cycle. I left it for 40 minutes idling and it still wasn't finished. Only when it got back to the dealer after a 400km highway run did it stop idling high from their forced regen.

[Ryan1kd]

Yep righto mate. I see your frustration. Certainly doesnt seem like it is accomodating for your driving style.
