OK, I brought my 99 V70 Turbo to the dealer because it was sounding horrible and asked them to tell me everything that they could possibly find wrong with it. They fixed an exhaust leak right away to clear a number of codes and then gave me their list.

One of the items was the "Accelerator Pedal Sensor." He gave me a part number (30683511) which comes up as Pedal Assembly and costs ~$120 (at Euro Parts Direct). After searching a bit, I've seen threads on other forums that say that this is suspicious. I also called Dean at www.eEuroparts.com (who has been a huge help in finding parts). He and others said that this part is only for vehicles with the accelerator that sends and electric signal to adjust the trottle, whereas the 99 V70 uses a cable (the pedal pulls a cable to open the throttle). Can anyone verify this or give me an idea what the code might have been and/or how that code should be interpreted for my car?

By the way, the other items in the list was that there is a vacuum leak that needed a turbo hose (Part #9161092) replaced, thermostat (Part #271664) and possibly the Mass Air Flow Sensor (after seeing if fixing the other issues takes this code out). Also, they previously told me I needed to change the turbo control valve (boost pressure valve) and the ABS Control Module.

Thanks again for any help on fixing these issues.

 

1999 cars have electronic throttle body (No cable)

I wouldn't mess with anything till you see what codes come back.

Was there any throttle body codes?

 

Hi tech,

They said they already got codes for the "Accelerator Pedal Sensor," the mechanic is supposed to call tomorrow with the exact code that came out so I can verify it.

As for the throttle body, codes came up for that earlier (a week ago) and they fixed that under the warranty. I immediately saw a dramatic improvement in how it idled and drove. Now I'm trying to just methodically go through every issue that can be found to fix what is most important.

Thanks! I'll definitely post what the code was when I get it tomorrow.

 

Ok sounds like a plan.

 

I talked to Dean at eEuroparts.com again today and he said he did some research and that part (electronic pedal) does apply to my car. I got the car back today and took out the kick panel and there was definitely an electronic pedal, so we are all in agreement. Unfortunately, I forgot to get the actual code from the mechanic. Dean suggested checking the resistance across the electronics to see if it was in the right range before automatically swapping out the part.

Do you happen to know what the resistance for this should be? Or do you know of another way to check if this is actually the part that's in need of replacing? Dean seemed to think it was unlikely that this went bad but he didn't have the spec value for the resistance on the electronics.

Thanks again.

 

Sorry I don't have the specs.

They are pretty rare to go bad.
But usually they will show up with throttle body codes.

I have only replaced 1 since 1999.

 

Hmm, interesting - sounds like maybe I should just take care of all of the other faults and then see if that one comes back (or find out what the actual code was and see if that reveals anything).

Thanks again.

 

If they were all cleared out see what comes back.
