recalibrating CVT in a JAZZ

hi,

my jazz recently has been jerking back and forth between 40 to 60km so after some read up in the forums i know i need to recalibrate the cvt...

so i called up a local honda dealer and they want $144 to recalibrate it...

i thought i might give it a go myself after reading this thread
http://www.ozhonda.com/forum/showthr...jazz+audio+din

i cant do it myself because the steps require a plug that comes with the car when purchased...unfortuntely i bought my car second hand and the previous owner did not have this also..

so is there anywhere else i can get this recalibrated for cheaper? or is there another way without that "TOOL" (BTW mines a auto )

any help would be great thanks in advance

the way to recalibrate your jazz is....

*Ozhonda takes no responsibility for your actions


reset the ECU ~ disconnect the NEGATIVE terminal for a few minutes. REconnect.
Jump in the car , drive in D and find a nice quiet long stretch of road.
Drive gradually until 60km/h then let go of the accell. and "coast" until a almost dead stop. Repeat this 3-4 times.

Congrats you recalibrated your CVT

LOL @ $144

it takes all of 15-20mins absolute MAX to do. however i'd get it checked out as there are a few things that can make auto jazz jerk. one of them being the start clutch in the cvt.

lol no shit, ur asking about resetting the cvt :wave:

but yeh ring around the dealers and i can guarantee u can get it done cheaper

so all i gotta do is disconnect the battery for 10mins
then drive up to 60k and let it slow down to almost a complete stop and repeat 4 times?
wow..thanks alot ben that looked easy to do...

now i just gotta find a long stretch of road :)

If its jerking between 40-60 @ light throttle is it quite possibly your EGR valve.

^ yah, very common

would that method be the same for recalibrating a cvt on a ek civic vti?

i finnally had the time and found a quiet place to do the cvt settings

and bennjamin it didnt work...it still jerked :S

as above ^

If it wont fix the issue its not the actual CVT - its the EGR needs replacement
Take it to a dealer

ohh ok...
any recommended dealers?
rick damelian gave me a sky figure :S

They are not hard to replace yourself, all you need to do it undo 2 nuts, replace the EGR valve and the gasket then re-fit the nuts.

thx edeauto...

im not confident enough to do that myself...

i just need to find a place that can do it for a fair price

Yes the same method used or the civic vti ek.

eks came in cvt? i thought it was only later models and jazz?


If you rin sydney ask Hanny's performance they are generally quite good on price and service. (do a yellow pages check)

yep
the ek vti sedans came with cvt

lol

more info for all of us lol. Ive driven auto ek sedans and they were auto like anything else :)

yeh its jus the vti sedan model. with the d16y5(vtec-e - hence the cvt) engine.
96-98ish.. i havent really seen many facelifted vtis but im guessing theyre teh same

very interesting - thats the ultra-economic engine that burns some exhaust @ the same time ? In the EG sedan too -

its the one that operates on 12valves from 0-2500/3000rpm.
then goes to 16v operation from 3000rpm onwards.
yeh i think it burns some exhaust gasses..
gets really crazy air/fuel ratios cos of the 12v operation.
i kno it uses the first and 2nd stages of the jdm d15b engine..
dunno if its in the eg. the vei model u mean?

took my car into the nearest ultratune coz 2 of the mechanics there used to work for honda...

they picked up a error code off the check engine light and says its showing a problem with the IDLE SPEED MOTOR...
does anyone know how much to get 1 replaced? so i can start getting money organised?

mum's jazz cvt seems a lil jerky also. when going really slow, and when u apply slightest throttle the gear engages more abruptly than it should. also sometimes on a hill when taking off, after i take my foot off the brake it rolls back a tiny bit, b4 the gear engages, and moves the car forward. you think this can be cured by a cvt recalibration?

recently had the fluid flushed by honda, seemed to help slightly but not that much.

thats exactly what mine is doing... but i think mine has a few other minor problems...

but get it checked out... i think the gears arent changing properly hence the roll back

Almost all cars burn some of the exhaust. It's call EGR, exhaust gas re-circulation. It helps for emission.

the engine we speak of is the vei - 66kw of grunt. A "low emissions" project afaik.

ahhh kz nah thats not my engine in my vti sedan.
i got the d16y5... spec'd @ 88kw ish...
lolz works well with the cvt.. fruggal assssssssssssssssssssssssssssssssssss on petrol

let us know how u go man.

looks like we have different people talking about different things, there are a few different faults which can occur so in all honesty it'd be best to take it to a dealer. they have the experience, training and the correct equipment to properly diagnose it for you

however for those that saw the thread title and want to know how to recalibrate the cvt, it's pretty simple as ben said

1. Drive the vehicle to warm up the engine and transmission to operating temperature (radiator fans operate twice).
2. Stop the engine. Shut off all accessories, and then restart the engine.
3. Switch on the headlights.
4. Select 'D' (drive) position.
5. Drive the vehicle to above 60kph.
6. Decelerate for more than five (5) seconds, without using the brakes. Perform steps 5 and 6 3-4 times.
7. Test drive from stationary several times to check the start clutch operates normally without undue vibration.

as mentioned another common fault could be the egr valve, this is more common in the 03 jazz. if the egr valve is faulty, during light acceleration the vehicle may hesitate or surge.
for the DIYer's this is how to replace it

1. Turn the ignition switch to the off position.
2. Disconnect the wiring coupler to the EGR valve.
3. Remove the two EGR valve 8mm mounting bolts and remove the EGR valve.
4. Remove the old gasket from the manifold. Clean the EGR valve seating on the manifold to ensure there will be no leaks with the new gasket.
5. Fit the new EGR valve and new gasket.
6. Tighten the two EGR valve 8mm mounting bolts to 22 N.m (16lb-ft) and connect the wiring.
7. Clear DTC’s from the PCM memory.
8. The repair is now complete.


otherwise it could require a cvtf flush, or even be something like the cvt start clutch or the trans control valve body or something along those lines.
(which is why i'd recommend taking it to a dealer in the first place)


and finally yes the ek vti sedan did come with the cvt, while i havent looked it up i'm guessing it's a very similar setup to the hrv of similar vintage

the mechanic said hes gonna test with a 2nd hand "idle speed motor" to see if this fixes the problem.. i called up rick damelian ( closest dealer to me) to get a quote on it and they couldnt find that name part and said it should be the " rotary air contol valve"

i will find out from the mechanic if the problem is fixed with a different part then i`ll get it done by him otherwise i`ll take it to rick damelian and save my money instead...

i`ll update again tomorrow, hopefully with some good news..

ok so its confirmed

need to replace the idle speed motor and the EGR valve

anyone know the price for the EGR valved replaced?

Dealer is your friend mate.

yeh..same thing the mechanic said... they couldnt fix the problem even though they tried with a different EGR valve... and suggested me to take it to a dealer
so i just gotta see wat they say at the dealer coz apparently the mechanics use a different device to fault find the 'check engine light' anyways... wish me luck coz i got a feeling the dealer is gonna charge me a arm and leg.

just abit of an update with my situation

i took my car to a honda dealer and they diagnosed that its a faulty EGR valve and needs to be replaced... so i gave him the go ahead to fix it..
they also said theres some electrical problems aswel...

so im shopping around for some auto electricians, dunno if theres any mobile ones that can come around my place...

anyways i`ll find out wat needs to be done by wed when i pick the car up

how much would that EGR valve cost to replace @ the dealers aye?

lol, i dont find this thread boring. Its relevant information to me. u dun have to read if u dont want to mate.

anywho, u could try cleaning ur EGR valve? my lude was throwing an error code, saying my egr is fkt. my mechanic rkns i needed a new one, which is like 400 bux. but i ended up just takn mine out, cleaning it, and it worked perfectly, no more error code.

i mite try the same for my jazz.

Why don't you just get them to fix the "electrical problems" it while its there?

If theres an electrical problem that is remotely related to the wiring for any of the sensors that they're looking to replace that could be causing the problem.

I realise that dealer service costs a lot of money, but it sounds like your spending a lot of money in time going to different people who just say take it to a dealer to be repaired....

Either way i hope you get the problem sorted as hesitations are the most annoying thing to deal with.

thats wat it did to my car...they replaced the egr valve for $470 inc labor and everything is fine...

i asked them how much to get it repaird too, but they werent interested in doing my business and referred me to a auto electrician, i only need the interior boot hatch light and auto window switch looked at..

which is my next step...

Dragging up the past here, sorry.
$470, WOW, they charge like real euro car dealers do.:eek:
Where on the Jazz 1.3 engine is the EGR valve located. Don't want to get the wrong bit off. Haven't tooled around with the Jazz much yet but have done heaps of euro repairs/restos over the years so not a mechanical nubie.
Are the EGR valves available aftermarket at anywhere like pertoject or aussie-fuel injection?
Will give this one a clean first if the fault comes up as that tomorrow when I check it.
Will keep all informed of my findings.
