Error messages V8V - Emission service and DSC service reqd

[morty1961]

Early 2006 V8V 27k miles (Garage Queen lol).

Last blast of last year after giving it some beans (end of October) I got the Emission service required and MIL light on ..... searched on here and found posts it would reset itself after umpteen stop/start cycles ... so I thought ok leave it till springtime when I re-tax it.

Garaged on a conditioner over the winter in the garage ... Ive started it up several times over the winter error message still there?

Started up yesterday and got an extra error message DSC service required traction control temporarily disabled and the TC warning lamp on?

Im hoping once I start using the car both of these will reset themselves but just a little concerned that the Traction control being disabled might cause a few issues????

Comments please?

I know that when my car came up with the DSC disabled it was diagnosed with a faulty brake pressure transducer (Which I think is the common problem). In addition, the car fault code was also a Pedal travel sensor. I got replacements for both and seemed fine since. I don't think parts are that expensive and relatively easy to fit. However, might be worth getting a OBD reader to correctly identify problems and fix accordingly or take to AM dealer.

Had the same issue, it turned out to be the brake pressure transducer - easy 10 min to fit yourself, and Astonmartinbits or a dealer will get you one in.

Emission thing likely O2 sensors. Get an OBDII reader off Amazon or adapter for your phone. Read the code, look it up online which sensor it is, clear the code. When it comes back again and same code then replace that sensor. Replaced all 4 of them over 9 years in my old Vantage...

Cheers guys am going to tax the car so will give it a few runs and see what happens

When I had the brake warning (It was Emergency Brake Assist failure on my V8V) I tried the pressure sensor but that didn't solve it - for me it was the pedal travel sensor.

is this the sensor...fits into the brake servo housing?

Yes, that's the brake pressure sensor.

going to get a cheapo OBD reader off Ebay (£10) and give it a go ... Im going to break and clean the electrical plugs on the O2 sensor and brake pressure sensor as well before purchasing any parts

[davek_964]

When I used a cheap fault reader, it didn't tell me anything - but I think some are better than others.

I still have my old pressure sensor - and unless I was unlucky and that had failed at the same time as my brake pedal sensor (which I doubt) it was perfectly fine. I'll send it to you if you want, and you can see if it solves the problem? I'd like it back - but it would give you a free trial to see whether that is the cause or not and hence whether it's worth ordering a new one.

Cheers mate I will get in touch if I need it to fault find!

OBDII will tell you emmissions related messages like the O2 sensors, but nothing on the brake transducer.... you just have to try that one

[morty1961]

Just for info where are the OBD ports and which ones which ... RHD car

[morty1961]

Bought a cheap reader off ebay and sorted the emissions service error .... the DSC error will have to wait until service in August as after driving and using the brakes etc the error hasn't self cleared so guess either of the sensors maybe faulty? Might just unplug the electrical connector on each sensor and give squirt of WD40 as there may be 'dry' connection with being laid up over winter?

[bogie]

No harm in a having a clean of the connector. If you change either one an OBDII wont clear the message though for these sensor errors. A couple of start/stop cycles of the car should though

[morty1961]

cheers mate hopefully it will sort itself once connections cleaned cleaned??

If you get lucky. If the sensor has failed though you need to change that first. The transducer went on my car at 81K miles and 10 years old. Easy enough to change, about £75 for sensor

[bogie]

Depends if you have a lift or other method of working under the car I guess.......for an hours labour at an Independant, may not be worth getting dirty

I reset the emission system service required fault code P0410 which apparently is the secondary air system. Anyway its come back so there must be a fault probably to do with the valves sticking on the pump unit so needs a look at? All fuses are ok as well which may have been one of the faults.

I also tried disconnecting/reconnecting the plugs on the sensors for the other brake system error fault (which has disabled the traction control system) but the error is still there.

I could really do with getting somewhere to reset the body fault code and see if it reappears?

[morty1961]

Davek I have emailed you from your profile page on here.

[morty1961]

Just had a service at Bridge Mill where they reset the Emissions fault code and so far it hasn't come back.....code was P0410 secondary air system pump. Anyway Adam advised using the car more may help this type of fault.

The DSC is coming up as a Yaw Sensor error ... a little involved to change out as its way down under the dash. So again may be a case of lack of use.!!!

I intend to use the car a lot more and enjoy it rather than it being sat in the garage gathering dust!

Anyone else had the Yaw Sensor changed out?
