specified value, replace the fuel injector.
4. This step determines if all of the fuel injectors are within 3 ohms of each other. If the highest resistance value is within 3 ohms of the lowest
resistance value, then all of the fuel injector coil windings are OK.
5. This step determines which fuel injector is faulty. After subtracting the highest and lowest resistance values from the average value, replace the
fuel injector that has the greatest resistance difference from the average.
