Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
This can be due to an internal electrical fault with the accelerator pedal sensor itself at the gas pedal.This sensor can send a false signal or no signal at all intermittently and cause this issue you see here.I have seen several of these fail in the past before and the accelerator pedal had to be replaced as an assembly to correct this fault.
What will have to be done from here is to have the fault codes checked/read out with a compatible scan tool to see what codes are set with this issue here.Once this is done any codes set will need diagnosed to locate and repair this fault.The scan tool is also used to monitor the accelerator pedal sensor to see if it is sending a false signal when this occurs.But I do suspect this is most likely the cause here with what you have described.
