2002 Ford Explorer Q&A
2002 Ford Explorer Question: I hear a knocking in rear inside panel, just under the door locks...
it is not the door locks, it starts the minute you put the keys in the egnition...it is behind the panel...what could it be...it is NOT the lock mechanism...it is below it..it is electrical and behind the plastic panel on drivers side next to the third seat. - chargerchrome
there is a fuel pressure sensor there but it should not make noise. have a shop listen to it to identify the noise. Roy - mastertech6371
