New Honda jazz 2006 advise needed service etc

[vixcrack]

Hello all. Just got a 2006 Honda jazz, se cvt. I'm in and around the East of England area. Can anyone recommend a good independent garage?. Also in terms of service, what are the main items that need to be changed, if I am to approach my own mechanic, please to ensure maximum optimisation of the car. The car has done 60k miles.

The car also threw a P0138 error code, which I believe is something to do with emissions. I manged to clear this using an obd2 machine. How serious is this fault and how much does it cost, to sort out the oxygen sensors linked to this issue. Many thanks in advance.

Hi, welcome to the forum

For a CVT car I would recommend using an independent garage with genuine Honda specialised  expertise. (maybe an ex Honda mechanic) Not just one that mentions Honda among a long list of other cars they can tackle.  Sorry I cant help with a particular garage but others might be able to help.

CVT Hondas require the use of Hondas own specification of cvt oil, which is quite expensive.  Whilst most garages would be able to drain and refill the cvt oil  its quite likely they would use cheaper universal cvt oil rather than the correct specification of  genuine Honda cvt  oil. (IIRC even Honda sell two types of cvt oil depending on the age of the car) . Also its difficult to drain all of the old oil from the gearbox,so if what remains was seriously  contaminated and degraded due to neglected cvt oil changes   the new oil will also become  contaminated.   In these circumstances it may be necessary to do a 'double flush'.  ie fill with oil, drive the car for a short while then do a second oil change. With lots of very expensive CVT oil  going to waste.

A friendly and competent independent  garage with no particular Honda expertise  may be able to do the job as long as you agree in advance the need to use the correct cvt oil.

As for the P0138 code  it really depends on the root cause. It might just be a faulty sensor, but it can be a waste of money replacing perfectly good sensors in the hope of a cure, if there an actual cause that needs fixing ,such as a leaking exhaust, faulty catalytic converter etc  .

Thanks very much this is very helpful. As I understand what needs doing is the oil, oil filter, air filter, CVT filter, CVT Fluids and pollen filters. Anything else that needs changing at service please?

[bill888]

The CVT filter cannot be changed without dismantling the gearbox!  Just change the CVT oil.

Perhaps buy the genuine Honda CVT fluid from Cox motors and give it to your chosen garage.  I think this was the oil I bought in 2023. Seems to be a tenner cheaper than in 2023:

You may need replacement sump washers, though I have re-used mine on first DIY CVT fluid change, when local Honda dealer sold me too small (14mm internal diameter) washers back in 2015:

Dimensions of 'used' 18mm washers I've retained:
18.1mm internal x 25.8mm external
18.2mm internal x 26.8mm external

Don't forget the 8x spark plugs.  NGK plugs work fine.

Does your car have its original Honda catalytic convertor and sensors, or has the cat been replaced by aftermarket cat and sensors, perhaps due to theft?

The P0138 code is may for the downstream (post catalytic convertor) sensor which could indicate an issue with the cat, if not the sensor.

Thanks very much. I'm not sure if it's the original sensors, it's only done 60k miles.

Also plesee in terms of coolant. If I cannot get the Honda type 2 coolant, what options can I get at say halfords or euro car parts please? I assume I will need 5 litres?

[bill888]

I'm embarrassed to say I have never had the coolant changed on my 2007 Jazz with 22k miles. I think I've only topped it up with a total of half a cup of type 2 coolant.   It is still blue in colour.....

I was thinking of finally DIY changing the coolant myself this coming spring/summer, but it is more likely I will have sold the car by then!

Some information I had gathered:

Honda type 2 coolant comes premixed

See this thread for how to change the coolant and comments about the Engine coolant plug.

You may wish to replace the brake fluid and inspect the serpentine belt for cracks too.

Garages often remove old engine  oil by by inserting a tube in the filler hole  (or dip stick tube ) and pumping it out.  By not  removing the drain plug they save time  ,the need for a replacement washer, and any risk of damage to the plug or sump or  liability for subsequent oil  leaks due to faulty refitting. This works well enough for engine oil changes  but I dont know if its possible with gearboxes.  But a rogue garage  might try pumping out as much oil as they can  ,then topping up with a lesser quantity of expensive new cvt oil.(but charging for the full  specified capacity)    The owner is unaware their 'new'cvt oils remains contaminated with a higher proportion of old oil. 
Its another reason for trying to chose a reputable garage.  Their attitude and willingness  to using the oil provided by you may help identify dodgy garages, or at least  warn them you are savvy enough they wont risk ripping you off in this way. They know you might ask to see the empty Honda oil container afterwards   

[bill888]

Gearbox takes exactly 3.2 litres every time I've changed it (3 times) using the level markers on the side of the grey plastic can.

I'd be worried if a garage returned an empty 4 litre cvt oil can to me

Hello again guys. My mechanic managed to service the car today so all good. He has asked me to get the 2 oxygen sensors, so he can replace them to try and fix the error P0138. I'm looking online, and I'm lost. Which specific sensors do I actually need please and from where? I've come across this website Honda Jazz GD 1.4 iDSI Lambda sensor - 83 hp Petrol 61 kW 2006 - 2008 L13A6 ▷ AUTODOC https://share.google/VkKaKXmbeydxioZuy
Unsure which ones I actually need? Many thanks as always.

[bill888]

I can only suggest you check the OE numbers quoted for the autodoc listed sensors, match those for your GD1 Jazz.

I note from the link you provided no single brand can supply both sensors.


Honda lists different part numbers for manual and CVT cars too.

You can find the honda part numbers from here:
https://www.parts-honda.uk/honda-cars/JAZZ

eg. 2006 UK 1.4 SE cvt
https://www.parts-honda.uk/honda-cars/JAZZ/2006/14-SE/ELECTRICAL-EQUIPMENTS-EXHAUST-HEATER/EXHAUST-PIPE-SILENCER/17SAA601/B__0200/3/22055

36531-PWA-903 (upstream, before cat)
36532-PWA-G02 (downstream, after cat)
(Perhaps supplied by Denso or NTK to Honda?)

fwiw, your mechanic may have asked you to supply the sensors, so they are not liable for any problems after fitting them btw.

Hello thanks very much. I've since bought the sensors, and hopefully my mechanic can fix it.
