Hello everybody,

I need help

When I am about 7000 rpm with my Aston Vantage, the engine goes to safety, at 500 rpm and it is impossible to accelerate. I have to stop the car, restart and everything is ok.

I have found several error codes, namely:
The p1578 "power less than demand" (Mike think that's the problem)
The p2104 "Throttle Actuator Control Sytem Forced Idle"
And the p2112 "Throttle Actuator Control System Stuck Closed"

At Aston Martin, they find nothing. No worries, all parts are ok.

Looking at the internet, I found these possibilities of problem:
1. Faulty connection to the accelerator pedal (pedal / module / position sensor / connection)
2. Damaged cable (open terminal) creating false contacts between the throttle and / or the accelerator pedal
3. Magnet of the butterfly motor peeling off the bracket and touching the engine.
4. Broken or dirty sensors

I have this problem for a year and no one finds anything.

Thanks for your help

Vincent

 

Sounds like problem I had once a few month ago.

Aston Dealer said a electric cable was lose.
Need to check the invoice what cable it was.

 

V8 or V12?

 

It's a V8

@Zettinger & HSM Precision: big thanks
