So I have a lumpy idle and engine light, code says control valve issue so have removed the valve with the sensor but can I get the torx screws out of the sensor, I can see they are five points but can’t find anything that fits, nodes anyone know what type and size I should be using?

I don’t know what screws you mean but torx have 6 points. 5 points are pentalobe. Apple loves the ******* things.

Assuming it's a 2002 wrxsti
If you are trying to remove these screws below on the idle air control VALVE, then you are trying to remove the motor assembly that rotates the valve - not any sensor.


The pressure sensor sits next to the valve on the throttle body.
