well when i say new it was off a 1.6 zetec escort.but is was only been on the car for a about two weeks.you can see that it is new.anyway it just seems strange that i put it on and its doing the same as my old one,which is telling me i think that it isnt the sensor.i'm a bit lost now.you say reset the ecu.would i just unplug it.i dont want to lose my radio code by taking my battery off.any more idea's.thank you
