Keep getting code 33 on my95wrx?
Is it to do with the mph conversion?
Anyone any Idea what could cause this, revs limited to4500 but i think this is a limp home mode as the ECU is in fault.

 

Code 33 is the vehicle speed sensor. I think on your car this is located on the drivers side of the gearbox, below the intercooler on a cable running up from the gearbox. Have you had some speedo work done or similar?
