Engine Coolant Temperature (ECT) Between 10-35 Degrees C (50-95 Degrees F)

FUEL INJECTOR COIL TEST - ENGINE COOLANT TEMPERATURE (ECT) BETWEEN 10-35 DEGREES C (50-95 DEGREES F)






TEST DESCRIPTION

Step 1 - Step 4:

The numbers below refer to the step numbers on the diagnostic table.
2. The engine coolant temperature (ECT) affects the ability of the fuel injector tester to detect a faulty fuel injector. Therefore, the test results are only valid when the engine coolant temperature is between 10-35°C (50-95°F).




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 displayed by the DMM should be within the specified range. Refer to the Example. The voltage 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, or large fluctuations in voltage that do not stabilize, indicates an intermittent connection within the fuel injector.
