The revs will drop as you turn the wheel anyway, due to the engine coming under extra load from the PS pump.

The sensor is mounted on the end off the fuel rail at the battery end, access it by removing the engine cover.I sprayed the sensor and the plug with contact cleaner and also used a small needle file to clean the connector pins.I was amazed at the difference it made as it must have been like it for a long while.

Is it possible that it could be a burnt out valve?
