  A: To disconnect the cable, remove it from the negative battery terminal.You can easily remove the engine cover.Get rid of that air intake duct.Remove the electrical connector from the TP sensor.After removing the TP sensor mounting screws, take off the TP sensor from the throttle body.When installing the TP sensor on to the throttle body, make sure that as a flat surface on inside of TP sensor rotating ring is align with this flat surface on shaft. The sensor will be correctly installed if it fits flush against throttle body and in case it doesn't fit flush against ignition system, then you have not aligned properly locating flats on inside of rotating ring and end of throttle shaft; slide off, realign them and reinstall it once more time.Conversely; after tightening up your TP sensor mounting screws firmly, reverse removal.Take out that air intake duct.Moreover, unplug electric connecting device from TP sensor.Also make sure you do away with all those nuts that hold down an old TP sensor.When installing the TP sensor on to the throttle body, align so that flat surface on inside of rotating ring for instance in TP's inside has been aligned with flat surface situated at throat shaft level as well as ensure that if it is flush with carburetor then you have installed correct sensing device while if not then inner finding flats provided by circular grove have not matched with end of fuel governor shaft and therefore separate these two by pulling out complete mechanism for looped alignment prior to reinstallation; correct placement requires similar procedures hereafter before you tighten everything back again clockwise at original position as above but now remember to take into account also screws securing TPS in place which only should be tightened adequately by your hands' pressure initially regardless of any use such tools or apply too much force since they are relatively weak screws.Otherwise, you begin by installing it backward from how it was removed.
