How to Check Fuel Injector Resistance with a Multimeter

Автокөліктер мен көлік құралдары

Using a Multimeter to Test Fuel Injector Resistance Ohms. Learn how to check fuel injectors to make sure they are working. You use a multimeter on the resistance settings and measure the ohms of the injector. All injectors should be within .5 ohms of each other. If an injector is out of the resistance specification, that injector is bad.
Symptoms of bad injectors are a check engine light with codes P0300 through P0308, misfiring, hesitation, poor fuel economy, stalling, and a poor idle.

    One other important point. You ALWAYS want to subtract the meter lead resistance from your reading.. So, touch the test leads together (in this case, at 200 ohms) you will probably get something around 0.3. If you have 14.8 Ohms for example after stabilizing, subtract the 0.3, giving you an actual reading of 14.5 Ohms. :) This is especially important with more sensitive devices, and can mean the difference between actual replacement, and not replacing when its actually bad. Good video!

Replaced that injector, all my engine warning lights turned off and it's running smooth. Your video very straight forward and the graphics made it easy to understand the discussion. Thanks!!!

    You forgot to mention that injectors are either high impedance or low impedance. A low impedance injector will have a resistance of around 2.5 to 3 ohms, while a high impedance injector will fall somewhere around 12-18 ohms. Good simple video on how to check 😎

    Also watch out for slow climbing reading if reading takes long to reach stable it is also likely a bad injector another check to do just to figure out what's actually failing is measure from each terminal to injector bodies sometimes it can be the internal wires have shorted to body if no reading across any terminal than there is likely a break in the wire hope this helps.

    Corrrect. Dirty or clogged injectors would read perfectly fine. The "solenoid" chris describes is simply a copper winding that becomes magnetized (just as passing current through a wire wrapped around a nail makes it magnetic). An injector with an intact solenoid should read to have a very low resistance.
