General: 70: O2 sensor or MAF causing P0130 on V70, 2000

[ocicat]

Hi
My first post so thanks to everyone for giving me a lot of reading so far. I have a V70 classic which is giving me a P0130 fault code. I would have just replaced the first O2 lambda sensor except it's a Denso set up which I think means only main dealer parts so it's £184 + vat. So I am using a handheld reader and checking O/P's and it would appear there is no data coming from the MAF (also denso). I know it's mentioned that the MAF should be checked in relation to a P0130 code but the car seems to be running very smooth with no issues, so could it be the MAF. Has anyone ordered Denso lambda sensors from the states they seem a lot cheaper?

Cheers Alan

Could you post up the part numbers for your MAF and front sensor, is it a wideband sensor?

Gary the part number for the sensor is 9202309 as confirmed by a main dealer from my registration, and I am sorry I don't understand the term wideband sensor (at least in this application)
I haven't yet found the part number for the MAF as I didn't think I might be going down that route.

Cheers Alan (on a bit of a learning curve, had the car six years and the only other problem was a headlamp relay failure) I had a 1989 740 before this, when cars were cars and easily understood)

So your car is a non turbo then? what cc is your engine?

Link to thread I posted when I changed my Denso lambda sensor.


Or search on Denso and Darcy to get to the thread.

Thanks for the link, I have ordered one from
http://www.fcpgroton.com/CSV70/csv70oxygensensors.htm part number 9202309 as quoted by my local volvo main agent. I picked this company because they state OE part and shipping was all sorted in the checkout. It will be about £110 compared to £216 even if it doesn't cure it (which I think it will) I'll have a spare for when it does fail :-) as I intend to keep the car...only done 23k in 6 years.
I'll report back as you did I expect it in day or so, probably have to pay about £18-20 tax I usually get nobbled.

Just to say that the part arrived from US at half the UK dealer price. It took me about 10 minutes to change it and clear the fault code and fingers crossed the fault has not returned.

ocicat,

I have exactly the same fault code, so thanks very much for the post and link. I will order from the same site (I have confirmed the part number).

It seems that replacing the sensor is a straightforward task, but I would be grateful for a quick run down on the job. (I have read the link to darcy's thread). What is the socket size needed and are there any consumables needed in addition to the sensor?

Thanks again,

V70 Classic MY2000

Hi If your only facilities like me are a set of ramps then the first thing to do from under the bonnet is to disconnect the electrical connection...easier said than done study your new one first to see where it latches. the retaining clip which the lead shares with the other sensor if you squeeze it and pull it should come out and you will see it is split where it goes in the hole. I pulled the electrical connector firmly to release it from it's mounting. This is all much easier than leaning over the wing when on the ramps DAMHIKT :-) When on the ramps or underneath in pit just use a 22mm (or 23mm not sure now) open ended spanner, there is just enough room/throw to make this work I put a bit of pipe on spanner to make it easier to free but it wasn't overly tight. There are no sundries required the sensor already has the grease on the thread. It was bit of a fiddle to get the sensor in and to get the thread to catch properly and the lead and plug get caught on everything, take care to not let the lead get caught, and wind the wires up and overstress them ... and yourself.
