Daihatsu Charade Oxygen sensor plus Berlingo is back!

Yes, I managed to source a genuine Daihatsu Oxygen sensor for our L251 Charade (Cuore/Mira) to see if I can get rid of a repeating Check Engine Light issue. I also look at the fuelling via diagnostics but don't really have a clue what I'm looking at...
Then I report back on my 2002 Citroen Berlingo HDi which needed a new crank pulley. Not a great job for access! Later Berlingos are somewhat easier.
Both vehicles are well represented in merchandise form, so do head to hubnut.org to find the store!
Oh and yes, we're aware that these Daihatsus are Cuores in Europe, and a Mira back in Japan (with smaller engines). In the UK and Australia, they wore Charade badges. You can find more Daihatsu antics on ‪@mightycarmods‬their latest video on a 24-hour kei car race is well worth checking out!

Tyre wear due to under inflation, made worse by the heavy front end and understeer. Check the upper engine mount shown here. Rubber looks as if it is breaking down. Some cleaning and anti rust spray wax also a good idea around that mount.

[@markwalsh8411]

Was about to say the same thing aligning may well be also needed but shoulder wear pretty evenly on both sides of the tyre usually indicates underinflation

[@phonotd]

Spot on sir.

[@bernardcromarty485]

Yup, under inflation!

[@richardhoneybun5509]

I just changed my tyres with wear on both shoulders. I run my tyres with higher pressures 🤔. My tracking did need adjusting though. Time will tell how they wear now.

[@phonotd]

@richardhoneybun5509 over inflation usually results in excessive wear on the centre of the tread face and the shoulders show quite a bit less wear. There are other factors of course.

[@tamaru_ne_taro]

Thank you for loving Daihatsu cars. from Japan😊

[@nealeburgess6756]

Your new oxygen sensor was working well on your diagnostic readout. That tells me your fuel injection system is controling the mixture perfectly at idle. You could do the same test at a fixed engine speed, say 2500 rpm. You are looking for the sensor output to change between approximately 0.2v to 0.8v in a rythmic fashion (just like it was in your idle speed test). If it remains at 0.8v the mixture is too rich (maybe fuel pressure too high) and if it remains at 0.2v the mixture is lean (maybe inlet manifold air leak, or low fuel pressure). I hope that helps you with your diagnosis.

[@anthonystevens8683]

Nice one Ian, hopefully the genuine )2 sensor will settle down as the ECU calibrates the E2E system during general running. Welcome back Bella! Great to see her in better health. I have to agree that pulley change would be a challenge to many and I would have probably paid someone who was recommended to do the job. Gone are the days when I could spend hours over an engine bay. She sounds good so fingers crossed Bella is feeling in much better. Thanks for sharing.

[@steverandall5814]

That was a lot of work on the Berlingo for only 60 pounds! I'm glad to see it still on the road and running so well.

[@torresalex]

Very glad to see Bella back on the road. She's a jewel

[@mariopizzamanmario8563]

We had an O2 sensor problem with our MY'03 Fiësta - it is due to crappy fuel. I put some decent fule (0% bio-ethanol) in, some cleaner (Wynns) and a liter of ASPEN-4stroke. That Aspen is fuel for equipment (which stands over time sometimes). It fixed the problem and so far hasn't come back. The problem is the crappy bio-fuel will foul your sensor over time. And yes modern cars are a bee-atch to work on, I think even the classic Mini is better. as tires go, I have good experience with Vredestein Comtrac 2 (Dutch premium brand) for all-season/rain/snow (they are under my Transit Custom van and last for 70.000km and that thing has 200HP). Really good and very QUIET too. I think you'll want some of those under the Berlingo.

[@km5lb11]

As an old fleet mechanic when working on anything exhaust, a little never seize or what some call copper grease will help when removing O2 sensors. 😊

[@OwenHolmes-qt8zq]

Those pulleys are notorious for failing and taking the cam belt out when they self-destruct. Great that you noticed before that happened. It looks very tight compared to other cars I’ve worked on with the 8 valve HDI in.

[@NotRubensDad]

Might be worth trying to get hold of an ex-Daihatsu mechanic on these niggles. My old Daihatsu dealer knew the cars inside out, always went straight to the problem. Now an indy post-Daihatsu but still same staff.

[@terryatkinson899]

My pulley on a scenic just fell apart and the garage used some wonderful black guey stuff to glue it back together 😊 worked fine and the mechanic said there's no way that's coming off again 😊 Atleast your o2 sensor is easy to get at😊

[@scottishcarenthusiastsandtrain]

Great little tinkering video on Chemmy and good to see Bella back again.

[@scalecrawlnl]

Great work getting the HubNut fleet back in action, I believe 'ship shape' is the correct expression. I hope to see much more of the cars in the 2024 season. Thank you.

[@iainmacleod4007]

I suspect under inflation of tyres as both shoulders have gone. My last Peugeot 306 had the 2.0 litre HDI engine and the crankshaft pulley disintegrated spectacularly on it. I was lucky to limp onto the garage forecourt of the local Rover dealer who were very good at accommodating me when the job needed doing there and then. They charged £25 an hour back twenty years ago and were excellent.

[@johnlladron735]

Great video, thanks a lot, Ian. Great to see those two cars running right/better.

[@RichardMarriott]

Japanese cars designed for the domestic market do sometimes have issues when replacing failed parts (with aftermarket parts) connected to emission controls. E.G. It took three attempts to replace a cat on a J chassis Honda I was supplying parts for, with different makes of cat before correcting the fault.

[@vivianhughes9347]

So pleased to see Bella is back, outer wear on tyres was always a problem on my M49. Will enjoy following your travels in the Berlingo. 😃

[@robames1293]

Both side wear on tyres can mean running under inflated, wheel alignment usually means one side. Often tyres need a bit more air than manufacturers recommend they err on side of softer ride.

[@daniellee9015]

Absolutely brilliant video Ian ❤👍 glad to see the fleet running great brilliant

[@davidflamee]

Always happy to see these 2 members of the fleet. Nice work H.N

[@MrAuriga67]

Ian, I would get Bella on a ramp, and just put a lever / bar on the lower arm bushes, to make sure there is no play or degradation in them. Cheaper than a new set of tyres that would get chewed up if these bushes had gone soft.

[@martinneumann7783]

Chemmy is well, Bella is healthy again. Good news! Thanks for the update and see you soon --- Martin

[@isaacplaysbass8568]

Fab news all round Ian. Happy 2024!

[@JLAGAN49]

I'm sure the OBD unit will have a graphing selection. You just watch for sensor one to switch between 0.5V and 0.9V approx. Sensor two should sit around 0.45V. Fuel trims and catalyst health viewable in real time.

[@MattBrownbill]

I fitted an O2 sensor gauge in my old Volvo and you could see it bouncing up and down merrily.

[@sammytheseal2307]

Sensor 1 should drop as low as 0.1v and fluctuate to 0.9v

[@nealeburgess6756]

The O2 sensor output was working fine in the video.

[@tonys1636]

That both outside edge tyre wear indicates under inflation to me, maybe a set of winter tyres as you live in Wales and helpful with the camping and towing on non paved sites.

[@frimleyfrodo]

That HDi sounds sweet. Fond memories of my 206D turbo which ran happily to over 200k averaging 50mpg.

[@neilb6029]

Not sure if anyone has already mentioned this but, I'd disconnect the battery from the Charade for 15 or so minutes to clear the ECU. This will reset the fuel trims and be a better starting point when you have a new o2 sensor. It'll find it's new normal much quicker.

[@staffiedave4033]

So happy to see Bella back.

[@Grimwriggler]

great news all round i love the berlingo

[@johnnorth9355]

New year tinkering. Excellent.

[@PaddyWV]

Good going! 👍 Bit of wheelarch tidying for Bella next?

[@RichardPolhill]

Always worth checking the airflow sensor when you get O2 sensor errors. If it isn't accurately metering the intake airflow then it can't accurately calculate that the exhaust is correct. I've had good results pulling the things off and flooding a load of solvent cleaner through to get the dirt off the hot wire in that plenum.

[@jfv65]

Also: check the engine temp sensor (probably somewhere on the side of the head). if it reads wrong/too low the ECU thinks the engihe is still cold and it will demand cold start mixture. Which in turn will cause the check engine light to come on.

[@tonysargent1699]

Nice to see you can get Daihatsu parts readily. One thing that puts me off a Chevrolet Spark, is availability of parts.

[@HubNut]

Not sure about readily. Amayama kindly managed to find one and added it to their website specially! It wasn't listed.

[@Summers-lad]

What puts me off a Chevrolet Spark? I hired one in Canada; they told me it was sporty and economical, but it turned out to be neither. And the boot lock didn't work. At least that's what I thought, until I told the hire company when I returned it. Turns out it automatically unlocks when the key is within a certain distance. Madness! Just because designers can do something doesn't mean they should.

[@andrewstones2921]

My understanding nowadays is that if fitting replacement oxygen sensors, MAF sensors or the like, it saves time and hassle and eventually money to just fit genuine items or good used genuine items rather then third party compatible parts. Also until a few years ago I’d use eBay or other marketplaces to buy cheap parts, but now I have learned that a good trusted motor factor or automotive parts shop is often cheaper and more reliable at supplying the correct parts.

[@bombakdik]

Thank you for this video. Nice one.

[@Kevin75668]

P0130 is usually a wholesale failure of the sensor. Freeze frame data for the code should give it's measured value when the code was set. If you're looking to monitor the sensor's health, Mode $06 data will list the various tests the ECM performs, the upper and lower limits, and the results of the last test. You can see if the sensor is working properly per the ECM long before a code, or even a pending code is set.

Perhaps time to have another go on Kitch's dyno?

[@chrisdowns1987]

Lucky with the O2 sensor threads then! I regularly have fun getting NOx sensors out of relatively new Mercs, last one was about a 2014 S-Class & the threads pulled out. Had to take the exhaust off to get a clear run at it and then re-tap what was left into a useable thread. The joys, especially when the sensors are around £450 each and theres a pair 😱 M20x1.5 tap I believe. Is Bella's throttle cable/potentiometer assembly loose or is that where it's supposed to sit? Couldn't quite make it out 😅 Thanks, as always! 👍

We replaced the sensor about a year ago so I guess that helped. That is where the potentiometer lives.

[@simonprime5541]

Ian , how are your pressures on the tyres - under inflation can cause wear on both edges I think? Alignment tends to wear either outer or inner dependent on toe in or toe out (again from memory) . Had a mini (original) years ago that did that - I checked the pressure every month and though thy were ok , until I borrowed my mates gauge and realised I was running around 8 psi low!! New gauge and new tyres.Hope you both have a great year , look forward to seeing your adventures.

[@HubNut]

We were at 34psi, but have gone a little higher this time.

[@richardhemingway6084]

I think those crank pulleys are known as 'harmonic balancers'. They are not a solid piece, but made up of shock absorbing rubber. So are prone to failure with age.

[@westmus]

And an fairly easy repair. It's just Hubnut being able to turn even an viper blade exchange into an big drama.

[@MrManBuzz]

​@@westmus Yeah, I kind of laughed when he said it was a pig of a job to undo the engine mount. From what I could see it's two bolts to undo the mount, stick a jack under the engine and lift it up. Hardly that big of a job.

[@HubNut]

Yes. That one seems within limits.

[@Roverturbo]

Your cat might be knackered, your no1 o2 sensor should bounce up and down 0.1 - 0.9 as it’s correcting, your no2 (after cat) should stay steady at a voltage, after the cat has corrected. The first bit where you showed the live data, this seemed to be the case, the second bit, the no2 o2 sensor was bouncing around. It shouldn’t do this.

True, but any sane person would've scrapped that car as soon as it developed an oil addiction and saved the money and expensive in keeping it on life support. I totally understand the emotional attachment to a car, but at the same time you need to be able to know when to let go. At this point it almost seems not too dissimilar to the kind of toxic attachment people get when they're in abusive relationships. This car is going to continue to give problems. And ultimately, it is going to get scrapped eventually, it's just a matter of when they decide enough is enough.
