Fuel Injector Resistance

WARNING: This page is about a different car, the 1997 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect fuel injector connectors. Using ohmmeter, measure resistance between injector terminals. See Fig 1 . Refer to the CHECKING FUEL INJECTOR RESISTANCE  table. With sensor temperature at 68°F (20°C), resistance should be about 13.8 ohms. Replace injectors as necessary.
