Resistance Inspection
WARNING: This page is about a different car, the 2018 Mazda CX-9. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- The low fuel pressure sensor/fuel temperature sensor cannot be removed as a single unit. When replacing the low fuel pressure sensor/fuel temperature sensor, replace it together with the high pressure fuel pump as a single unit.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
- Remove the plug hole plate. (See Plug Hole Plate Removal/Installation .)
- Disconnect the low fuel pressure sensor/fuel temperature sensor connector.
- Measure the resistance between low fuel pressure sensor/fuel temperature sensor terminals E and C.
