2001 YRV 1.3 Pre-Cat Lambda Oxygen Sensor

Forum: 

Hi, I'm wondering whether someone might be able to impart a bit of knowledge!

I have had the malfunction light on intermittently on my YRV for the last few months - to begin with it went off after a bit of driving but for the last couple of weeks it has stayed on. I checked the error codes and got P0133 and P0135 - after clearing these only the P0135 comes back on which is "O2 Sensor Heater Circuit (Bank 1 Sensor 1)". I understand that Bank 1 Sensor 1 means that it's the pre-cat sensor.

I'm not noticing any problems at all (fuel consumption fine, drives same as ever, etc) but I assume the sensor needs replacing. Is there somewhere I can cross-reference part numbers to try and find one reasonably cheap? I've had a look at http://www.denso-am.eu/catalogue1.asp?make=DAIHATSU&model=SIRION which suggests that I need the DOX-0236 denso model. There is also a DOX-0113 on there for models after 12/2001 - are these actually any different?

I also contacted www.lambdasensor.com who gave me the Bosch model as LS602 for pre-cat fitting.

Any help much appreciated!

Thanks

Oxygen/Lambda Sensor

Ovolactohippo,

Firstly I have a "thing" for Lambda sensors and have done quite a bit of www researching so I think I can help.

I had a look at the Denso catalogue and you are correct that it comes out as a DOX0236 for your car, and that would be the one I would use. I personally would not use the Bosch ones, not that there is anything wrong with them but Denso is the Original Equipment Manufacturer (OEM) for Daihatsu so it makes sense to stick with what we know. The Bosch one may be a universal one and not 100% correct, but OK.

Now to where to get a cheap one. I can tell you for nothing a Daihatsu one will lighten your wallet to the tune of £300. Yes. Ouch! The good news though is all my checking on the www has paid off.

These guys http://www.sparkplugs.co.uk/pages/pricing/ccp/Denso-Lambda-ccp.asp seem to have it sewn up, and the prices are very, very good. I would not quibble at these prices. So have a look and see what you reckon.

I have bought spark plugs and a DOX0113 from them and they give good service. And on the subject of DOX0113 you ask the question as to whether they are different. I am sure they are - they certainly look different.

Just quickly on the wider topic of Lambda sensors I recommend treating them like long life sparkplugs and change them every 50,000 miles. You say you can't feel any problems but my guess is you will see a huge difference in all performance apsects after replacing your Lambda sensor. When I replaced the ones on my Sirion I could not believe how bad the car had been running compared to the improvement. It was unbelievable.

I also recommend you change the rear one as well (if it has one). For two reasons, one being this is the one that "looks after" the catalytic converter - it monitors its effectiveness. And secondly I have read that Toyota based systems are unusual in that the rear sensor actually does play a minor role in fuel trimming (the front one is the main controller), which is an economy thing and is important with the price of fuel.

Coincidentally I am about to order DOX0236 and DOX0113 for my new (secondhand) Materia I just got. That way I know they are good and the car is running as it should and at the prices I see it is no different to buying a tyre.

So knock yourself out and just do it is my advice.

Regards

Thanks for the incredibly

Thanks for the incredibly detailed reply!

If it weren't for the lack of job at the moment I think I would get myself the two from Denso as you suggest. However, looks like Daihatsu Dave has a second hand original one going spare so for the moment I think I'm going down that road.

Thank you for all the advice - I'm intrigued to see whether a new set of sensors would make the car drive better.

Hi, swapped both of mine out

Hi, swapped both of mine out for some NTK (NGK) ones, on my YRV Turbo as it appears that these sensors need changing after so long. There was nothing really wrong with the old ones, but have noticed the car has a better idle etc.. Smile

Sorted!

Thanks to DaihatsuDave for the sensor - posted it incredibly quickly and I had it on Saturday morning. Changed it over Saturday afternoon and no more malfunction light, and I am inclined to say that the car is driving a lot more smoothly than it was. I've only had it since February so I'm thinking I was just used to the way it was - I don't think the improvement is merely psychological!

Thanks to everybody for their help - I'm very impressed with this forum! Smile

Well sorted!

Ovolactohippo,

Glad you came back to us with a sign-off on the thread. Even happier you got it sorted and the car is running well. I will wager your fuel consumption will improve now.

Regards

Success!

ovolactohippo, glad its sorted happy to have helped Smile
Regards Denso lambdas DOX-0236 is for M100/200 series 1300cc Sirion and YRV, both upper and lower are the same. The Turbo has a different upper.
The 0113 and 0109 also have a massive cable length of 750mm compared to 250mm on the 0236? They list many DOX variations with some Daihatsu's produced with different plug connectors, cable length as well as body design too.Choose carefully Wink
Denso have also added the newer anti-silicon contamination Planar lambdas to add more confusion to what fits what haha Biggrin

I'm new here... so play nice

I'm new here... so play nice ok.

Just bought a YRV last weekend. I must of been caught in the excitement but I somehow failed to notice the engine warning light glowing away. I've got an OBD2 reader and app which has returned the same results as above with 2 errors for 02 sensors in the drive train. So, I want to fix the problem after pay day. Anybody know how much damage driving with faulty sensors will do over a short period? Or is it simply damaging my pocket with poor fuel economy. Also, with access to ramps and tools is this a quick fix for diy?

Hello Newbie!

Okay.

This is a now common problem rearing its head on the Daihatsu Range of Cars. Down to Age and Mileage it seems this problem then occurs.

First off driving with faulty sensors will mean more fuel and possible damage to the CAT on the manifold over time.
Ideally you shouldnt be driving with the 2 Lambdas at fault, but if you want to chance it, then go for it. I think the only main issue you will witness is the lack of MPG to the tank of fuel you will put in. But also the ECU will be compensating for the readings until the lambdas are replaced.

AS for DIY repair and replace? Yes its possible. I managed to replace the Top Lambda without issue, but I used a proper O2/Lambda Socket (Socket with a slit cut out for the cable). As for the Exhaust one, then this was a Nightmare, as the Lambda was solid and as much as I tried with the proper socket it was rounding off the Lambda. Also you need to be careful when taking the Lambda off as you are putting undue stress on the Exhaust and Mountings. Worth a shot if you want to try first, but I ended up taking mine to a garage to have them do it. Apprrently they had to remove the exhaust first, put the exhaust section into a vice and removing and replacing the Sensor this way.

Good Luck.

Ta!

OK, I'm sure I've made a mess of this thread. Was expecting a straight forward chronological set up with my comment at the end but hey, I'll get used to it. Thanks for the advice, I'll take it easy until the part is ordered!

Chronological setup!? Not

Chronological setup!?

Not sure what you were expecting us to provide to you? If I knew when your engine/Cat would go bang because you didn't change the O2 sensors then I would have to look at the following:

1).. Get the Crystal Ball out of the shop
2).. Get Doc Brown to fire up the Delorian
3).. Have Doctor Who visit in his Tardis.

The end comment if you want it, is get the O2 sensors replaced before you cause any damage.

Simples! Wink

Noooo!

I meant the thread structure!! Not the answers, they were great. Its the forum structure I was referring too. It confuses me.

Hello and welcome new

Hello and welcome new member.
I think you mean how the posts taper off into almost single letters on each line or are in no chronological order?? You have to log in helps and you can mess with the settings...they are just under the original first post (Comment viewing options).
Hey Bob have you got rid of your double post virus haha Wink

Thanks for that. I was also uber confused at the thread layout with new posts popping up in the middle of the page rather than the bottom. Sorted it out now though Smile

If you use an Ipad and Safari

If you use an Ipad and Safari and don't change the settings it looks really horrible. Especially when you get loads of threads as the word become 1 letters per line Sad
