What does injector circuit high mean?
A fuel injector that has become dirty or plugged. A fuel injector that is shorted internally and therefore causes high-voltage draws. A malfunctioning electrical harness between the PCM (Powertrain control Module) and the injector.
What is an injector control circuit?
The fuel injector circuit controls the fuel injectors and commands how much fuel and when to spray the fuel. This code is set when the ECM detects out-of-range sensor performance for either the voltage or resistance of the injector circuit.
How do I fix code P0268?
What repairs can fix the P0268 code?
- Replacing the injector if it has shorted and failed the resistance tests (should be installed with new injector seals)
- Repairing the wiring or connections between the injector and ECM or injector module for a shorted harness.
What causes an injector circuit malfunction?
Another cause of the P0200 code that can cause an injector circuit malfunction is an open or shorted injector. The electrical circuit is “open” and not closed, meaning that the electrons will not flow, and be due to an injector coil itself being broken.
How do I fix code P0273?
What repairs can fix the P0273 code?
- Replace the #5 fuel injector.
- Clean fuel injector.
- Wires may need to be replaced.
What are symptoms of bad injectors?
Here are a few signs there might be something wrong with your fuel injectors.
- The Engine Misfires. Dirty fuel injectors may cause your vehicle’s engine to misfire.
- Idling Gets Rough.
- Your Gas Mileage Tanks.
- The RPM Needle Starts to Dance.
- Your Car Won’t Start.
How do you check a fuel injector wire?
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.
Can I drive with bad fuel injectors?
While fuel injector problems usually give warning, driving your vehicle for a long time with a clogged or faulty fuel injector can cause problems. Increased fuel consumption. A noticeable increase in tailpipe smoke and emissions. Rough idle and hesitation during acceleration.
