How many ohms should a fuel injector have?
They will range from 12 to 17 ohms. Low impedance injectors are found on high performance and larger injectors. They have much lower resistance, typically around 2-5 ohms.
How do you test a Toyota injector?
Put a long screwdriver to your ear and the other end on the injector, and listen for clicking. The clicking indicates that it is working. If no noise is heard, the injector is bad and should be replaced. If it is clicking, the injector is clogged and should be replaced.
How can you tell which fuel injector is bad?
Answer: The easiest way is to listen to the injector with a mechanic’s stethoscope or a length of hose. You should hear a clicking sound as the injector’s valve opens and closes. However, if the injector is clogged, even if it’s working it’ll not spray any fuel.
How do you check a fuel injector circuit?
Fuel Injector Resistance Testing
- Turn the multimeter to “Ohms.”
- Place the multimeter leads into the fuel injector plug terminal.
- Read the Ohms, or resistance, produced by the fuel injector.
- Test all the fuel injector Ohm readings.
- Replace the injector if the Ohm value is significantly different than other injectors.
What is the resistance of a Toyota Corolla fuel injector?
NOTE: The 1.6L Toyota resistance specification is: 13.4 to 14.2 Ohms. Let’s find out what your specific multimeter test results mean: CASE 1: The fuel injector resistance of all 4 was within specification (or similar). This confirms that the fuel injectors are OK. Specifically, that none are shorted or open internally.
What kind of fuel injectors do Toyota use?
You can also turn to the Toyota Parts Center blog for tips on how to replace fuel injectors. OEM fuel injectors are optimized to meet the specific performance needs of your model year. OEM fuel injectors are made from quality materials that last as long as the original. Cheap, aftermarket injectors wear out quicker.
Are there any OEM fuel injectors that last?

OEM Toyota fuel injectors are made from Toyota factory specs and will be an exact fit part. When you buy your OEM Toyota parts from us, you get a no-hassle return policy and save money thanks to our wholesale pricing.
How to test the resistance of a fuel injector?
Measure the resistance of the fuel injector across its two male spade terminals with the multimeter test leads (see the illustration in the image viewer). Write down the resistance value that your multimeter records for the specific fuel injector you’re testing.
