Gallardo EPC 6 - 10 error light

[P101]

I was out for a drive yesterday (Gallardo) when the dash kept beeping and flashing up EPC 6-10 then clearing again. This went on for some time. The cars performance didn't seem to change at all.When I got home I plugged my diagnostic tool into the car and got the following pending codes.

P0226 Throttle / Pedal position sensor / Switch C circuit range / performance

P1227 Fuel injector 3 circuit low voltage

P0507 Idle air control system RPM higher than expected

This morning I disconnected the battery hoping this would help, but it didn't. Now on start up, the revs go up to 2000rpm and down to about 1000rpm over and over, is this Rev hunting??

Does anyone know if these codes/errors are connected??
Or any tips on how I might be able to rectify this problem?

Could just be a vacuum leak causing the hunting , perished hose or fallen off ,could even thrown the other errors up !
Worth a look !

Thought I would have an ask around, any pointers in the right direction may help when you have a look.

Mine clears itself, for about 5 seconds before coming back on.

Pop it down to Bournemouth is prob the best idea? Could be simple but means taking time to work through all the pipes and connections to check things and might need to swap out a sender or two to find the fault.

throttle bodies requiring cleaning perhaps?
As pointed out by Lambobrum, visit to someone who knows what they are doing?
As mentioned in another post, why not give Mike Pullen a call? 01444 455100.
He's even given me advice tips over the phone in the past.

I hope if it is the throttle bodies they just need a good clean, as replacements seem to cost £1800 + vat each!! Arnt they the same ones that are in some volvo's? I seem to remember hearing this. My Mate Mark (Needforspeed) is gonna have a look, he is usually pretty damn good at this type of thing, if all else fails I will probably have to take it to Emblem (When I have saved some money!!)

I'll drop off some extra matches for Mark then

Cheers Kurt, drop off your Gallardo too, might be useful for spare parts.

think they rarely need changing, just a good clean out as they get dirty quite quickly.
mine needed cleaning as idle was a little eratic and it sorted it out.

Hope it only ends up being something minor. If it does end up needing a trip to Emblem and you do need to replace anything that is really expensive, send me a pm and I will tell you where I got my actuator from and managed to get 17.5% discount. I did tell Martin where I managed to get it from and he was going to give them a call in future when he needs parts.

Oh saw you on Saturday morning pulling up at Tesco in a very loud fashion! I was just driving out as you were parking.

We had a look at the throttle bodies, they were quite oily, the left hand side bank 6-10 had it's flap fluctuating a bit, it was cleaned up and for about 2 miles ran as it should. Then the error lights and erratic idle revs came back again! So its narrowing down where the problem is a little.

Thanks, I'll bear that in mind.

Sure it will all be easily solved for less than £10k!!!

£200 actually, took it to Emblem and they fixed it.

Was it a sender then?
