Injector Coil Test Procedure:

Example - Voltage Readings:

Chart Test Description: Number(s) below refer to circled number(s) on the diagnostic chart.
1. The flrst second of the voltage reading may be inaccurate due to initial current surge, therefore, record the lowest voltage displayed after the flrst second of test. The voltage reading may increase throughout the test as the injector windings warm and the resistance changes. An erratic voltage reading (one that jumps up and down) indicates an intermittent connection within the fuel injector.
2. From recorded voltages (see example), identify the highest voltage reading recorded (other than those above 9.5 volts). Subtract all other voltages from the highest voltage recorded. The subtracted value for any injector must not exceed 0.6 volt.
3. To check the mechanical (fuel delivery) portion of the fuel injector, perform an injector balance test.
