Is there any point in simply disconnecting this sensor and then driving with it like that to see if the symptoms are the same or similar? I know that I accidentally left mine disconnected for a while and it became obvious there was a problem straight away. Soon as i cleaned it and reconnected it the difference was huge.The problem is that the sympom occurs only while driving under load which means a continuity check would not help much stationary, unfortunately that's a kind of fault when the sensor must be ruled out first cos chasing some wiring issue wihout that is feckless
