the old (to be replaced) pressure sensor as shown in Figure B–6
below.
c. Turn the 7/8 in. wrench counterclockwise to loosen the pressure
sensor until it is able to be removed.
13. Remove excess seal tape from the threads at the opening and check

the flat surface and not back inside the cell.
Threads showing signs of galling indicate a possible leak. Contact
Service to arrange for repair (refer to “Service Contact” on page
