Inspection (MPV, Protege, Protege5 & 626)

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Mazda Tribute, 2002 Mazda Protege5, 2002 Mazda Protege, 2002 Mazda Millenia, and 2002 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect TP sensor connector. Using an ohmmeter, measure resistance between terminals "A" and "C" of TP sensor terminals. If resistance is not as specified, replace TP sensor. See TP SENSOR RESISTANCE (MPV, PROTEGE, PROTEGE5 & 626)  table.
