V70XC: V 70 XC 70 AWD 1999 B5254T non starter

P1132 code is for VVT soleniod circuit.

You won't see any useful data from OBDII for the front sensor as it's a wideband type.

The log looks OK but what are the fuel trim figures?

Thanks for the reply Chris
Will have a look at the program i am using to see if this gives me these figures but will be tomorrow as the laptop is currently in use


I am reading through the article on the link in your reply

If it is the VVT can i just replace it with a new one or working second hand one or does it need software as well ?

[Chris_Rogers]

No software as far as I know.

If it's the first time you've seen this code I'd reset it and see if it comes back.

Engine oil condition is the first thing I'd look for.

[big_yin]

This code was there before
I did reset it but after 200/250 miles it would come back again.

The last time i did a reset i was in the Netherlands and then all the other problems occurred with the car revs all over the place and running very rough and drinking 12 MPG

The ETM , MAF and the Front Oxygen sensor have been replaced now and the car is running normal even though the check engine light is on and code P1132 is present.

I will do a reset tomorrow again and see what happens.

If the oil is old it can effect the working of the VVT?

According to your model and year the error code P1132 = Volvo ECM- 280A

which is to do with front O2 Sensor

The same code in the link is for a `99 S80 T6 although OBD11 codes they are different depending what model you have!

Although these sensors are cheaper and may even have the same number on them they are not as Volvo as they are made by Bosch to Volvo spec. and cannot be sold as Bosch because of copyright........The same thing happens with the Spark Plugs and that is why a Volvo will always run better on the Volvo plug.

Yes, i understand that £80 is better than the £230 from Volvo but you only get what you pay for.

I learnt the hard way some 6 yrs ago and my life was a misery due to bad O2 sensors on the 960. I ended up with 4 copy ones and the only ones that gave no bother was the correct Volvo components.

So at the end of the day we all choose our own paths, some with not so much aggravation!

The front oxygen sensor has just been replaced by a genuine BOSCH with the same part number as the original one that was installed and checked on the BOSCH website.
Before this was replaced the car wouldn't run for long before starting to hunt and drink again and that is one thing that isn't happening now.


Could this new sensor be a dud ?

[Chris_Rogers]

My mistake, Keith is correct on the OBD code, comes of relying on memory!

This is a front O2 sensor code, but note that the code could be set by a poor rear sensor.

I'd suggest that you give it some time, it maybe the CAT is a bit contaminated from the rich running and needs to burn off the soot, try and do some long runs and see if this helps before spending more cash.

Have a look at the STFT & LTFT figures, this should give you some confidence that the front O2 sensor is OK.

Hi,
I always get slagged at for mentioning Genuine Parts (not yourself) but as said the numbers don`t mean they have the same spec. as the Volvo one.

Yes, you may be ok with out a hitch at £80 but why do Volvo sell them at £230 when they know people can go to Bosch and get the same thing for one third the price.......surely it is foolish to do that......but perhaps they know things that we don`t??

You may have a duffy sensor it says in the readings that it could be?

When it is such important items to the running of the engine i always buy genuine parts especially with turbo`s, they ALWAYS work. Otherwise one just doesn`t know where the hell you are!!

[big_yin]

ok

So don't have to look at the VVT then.

I will clear the code before driving to work tomorrow morning and see what happens .

960KG
But if the both Bosch parts have the same numbers on them shouldn't they be the same?
How can they otherwise keep them apart if one is the Volvo part and the other one a part directly from Bosch ?

Yes, i understand where you are coming from but i have had no more trouble with O2 sensors since buying from Volvo and i have had three more Volvo since the trouble with the 960.

A T4 owner on the X40 site quite a few months back asked me about the numbers on his O2 sensors he was buying cheap £90 and i replied with the answer that they were the correct numbers.
Shortly after that he did not use the car then when the MOT was due it did not pass on emissions, he knew he had new O2 sensors so changed most other things, still no change, i told him to bite the bullet and just get new ones from Volvo and it passed ok but did cost him 2 MOT`s on top of that, expensive learning, but was similar to what i went through myself.

When you buy from others on-line who is to say if they are Chinese copies?....they will all look alike...


It is everyone to there own, for me myself Genuine all the time from the dealer whatever especially as said with a turbo.

What i don`t understand is mark up from £75/80 to £230 at Volvo there is too much difference for them to be identical parts!
