What is the normal injector resistance?

The normal injector resistance for fuel injectors is typically around 12 ohms, with a tolerance of plus or minus 2 ohms. This range is important because it indicates the electrical specifications necessary for the proper operation of the fuel injector.

Injectors with resistance within this specified range ensure that they can effectively operate at the intended voltage and current levels, allowing them to open and close properly in response to control signals. If the resistance is too low, it can indicate a short circuit, whereas too high resistance may suggest a problem such as an open circuit or wear that affects performance. Maintaining the injector within this specified range is crucial for optimal engine performance and emissions control.

Knowing the standard resistance value helps technicians in diagnosing issues by allowing them to measure the resistance directly and confirm whether the injectors are functioning correctly according to manufacturer specifications.
