I was reading my codes on my ECU. and I threw the TPS sensor.

I have an sr20det.I noticed whenever I would push down the gas pedal there would be a second delay and then the rev's would raise.

So I went ahead and assumed it was the TPS sensor.Now I read the FSM on how to adjust it.

iirc. the TPS sensor should be at a .5volts when the throttle is closed.

I pulled out my multimeter and took some readings, along with some pictures.

These are the reading with the car turned on. from the female connector.Far left pin:Middle pin:Far right pin:

Those should be accurate readings from the wiring harness to the TP sensor itself.Continuity still exists on the ground wire, even when the car is shut off. so thats a good sign.

No matter how much I try adjusting the tps sensor, the most volts I can get is .20Does this mean the TPS sensor is bad?

I just need a few second opinions before buying a new one. Does anyone know the Correct place to put the multimeter probes to get the .5v reading??
