Hi there,

I work for Holden, so I'll try to help you here.

Is the power loss a complete cut (like turning the key off) or gradual loss for however long you have the pedal depressed?

Strange for no DTCs stored, did a Holden dealer scan the vehicle?


Customer: replied 2 years ago.
Hey Gary,
No the engine is still running but it is like it just goes back to idle speed. if you release the accelerator and re-apply it it has full acceleration again. If you hold the accelerator constant it will loose power again. its almost like it looses signal between the accelerator and the throttle body.
Sorry Gary I should have mentioned that I own a small workshop in West Gosford and we have scanned it with a G scan.
One of my guys has just told me that there are 2 codes 067300 and 067400

Hi again,

Your DTCs aren't what I would normally see, but this may be the fault with the car if it has APP issues.

See attached file for P2138.

Hope this helps.

Thanks Gary, the customer has had to take the vehicle and is talking about taking it to the dealer. I will try to get the vehicle back to check the accelerator connections.

Hi again,

If the dealer finds the owner's problem, then hopefully you won't need to see it again.

I hope I'm on the right path for both you and the owner.
