well again I have the warning coming up..it was just in last month..and now it is back..when I took it in last time a sensor was changed i think I was told they received the complete pump,took the sensor off the new pump and replaced the sensor only, as to replace the whole pump would of been a big job..and when they put the car on the scanner it was only showing it was the sensor.i was told to change the pump I think they said the rear bumper cover needs to be removed..well now it the time to do it,as iam changing the cover now..i should call and tell them I have it off now,,as you can see the whole pump now,and it would be easy to change it ..
