How do you test a diesel injector?

How do you test a diesel injector?

Connect the clip of the automotive test light to the negative terminal of your vehicle’s battery. Then take the pointed tip of the test light and touch it to the small bit of exposed wire on the fuel injector connector. The test light should light up if the injector is functioning properly.

What voltage do fuel injectors use?

Most injectors use 12 volts to energize the coil, and the driver energizes the circuit by pulling it to ground. When the injector is energized, the voltage drops to almost zero. If it does not, it could mean an open or weak connection in the wiring harness or open coils inside the injector.

How do I check my injector voltage?

Voltage Testing

  1. Turn the ignition key to the “On” position. You do not need to start the engine for this test.
  2. Disconnect the electronics plug wire from the fuel injector.
  3. Turn the multimeter to “volts.” Insert the black and red multimeter leads onto each side of the fuel injector electronics plug.
  4. Read the multimeter.

How much does it cost to flow test injectors?

The cost for flow testing is $15.00 per injector.

Can You Recode Mondeo 2.2 ST TDCi injectors?

Always recoded Mondeo injectors fine but they are normally 2.0 litres and not 2.2 so maybe thinking of retrying with a different scanner. Used codes from injector numbers on injectors although these do match the label on the cover. I did recode them in firing order as neede to with the Launch.

When to revert ECU coding on Mondeo injectors?

Coding old / worn injectors will revert the ECU coding to what the injection characteristics where when the injectors where new, not in their now aged condition. (and we know what the reputation of Mondeo injectors are when they have done some mileage). As I said, I stand to be corrected by one with better knowledge.

What do the codes on the injector bodies mean?

The codes on the injector bodies are the calibration codes for that injector when it is a brand new (or fresh recon) unit. Over a period of time the injector characteristics change with wear. The engine ECU can monitor the performance and make small running adjustments to the base line settings it has from the original coding it was given.
