Default High TPS voltage

I've got an OBD1 code 24 saying the TPS voltage is to high. I can see an issue causing it to have low voltage, but to high? What could cause that?

It can happen. Back probe the sensor if you doubt the OBD and confirm the voltage sweep.

Use safety pins to backprobe the connector if your probes dont fit. Dont force them or you can damage the connector.

The problem got fixed with a new junkyard TPS. Wasn't a wiring issue, but bad sensor
