Fuel Injector Coil Test

TEST DESCRIPTION

Diagnostic Chart:

Schematics:

The numbers below refer to the step numbers on the diagnostic table.
3. The first second of the voltage displayed by the DMM may be inaccurate due to the initial current surge, therefore, record the lowest voltage displayed by the DMM after the first second of the test. The voltage that is displayed by the DMM should be within the specified range, refer to the example. The voltage that is displayed by the DMM may increase throughout the test as the fuel injector windings warm and the resistance of the fuel injector windings changes. An erratic voltage reading, large fluctuations in the voltage that do not stabilize, indicates that there is an intermittent connection within the fuel injector.
