This is a scary situation if the problem happens while you are driving down the highway or in heavy traffic.

Can a failing TPS cause a car to stall?

It can be difficult to tell the difference between a failing TPS and a malfunctioning or clogged idle air control (IAC) valve, so electrical testing and cleaning of the IAC is recommended. As mentioned, a failing TPS can result in random engine stalling at idle, but this can also happen under driving conditions.
