P0202 indicates that the ECM has detected a malfunction for the cylinder 2 injector circuit. The code is set once the ECM detects out-of-range voltage or resistance. The malfunction causes the ECM to set a Check Engine Light and a failsafe mode. This failsafe mode is to protect the vehicle from further damage.
What causes a P0202 code?
Code P0202 sets when the Power Train Control Module or PCM sees an open or short in the #2 cylinder injector circuit. A vehicle with this code should be taken in to a repair shop for diagnosis.
How do I fix code P0201?
What repairs can fix the P0201 code?
- Cylinder 1 fuel injector replaced.
- ECM replacement.
- Repair or replacement of wiring issues.
- Fixing poor connection faults.
What is injector circuit malfunction?
P0200 means that the engine control module (ECM) has detected a malfunction in the fuel injector circuit. The fuel injector circuit controls the fuel injectors and commands how much fuel and when to spray the fuel.
What does it mean when it says injector circuit open?
Diagnostic trouble code (DTC) code P0201 stands for “Cylinder 1 Injector Circuit/Open.” It indicates a potential problem with the #1 Fuel Injector Circuit, like a broken wire, loose terminal, burned out injector coil, or some other circuit interruption issue.
What is the fuel injector?
What Are Fuel Injectors? Fuel injectors spray fuel into a car’s engine using electronic controlled valves, capable of opening and closing many times a second. They have an atomising nozzle that distributes the petrol or diesel evenly, for optimum combustion and efficiency.
How do I fix code P0203?
What repairs can fix the P0203 code?
- Repair or replacement of wiring harness.
- Cylinder 3 injector replacement.

How much does it cost to fix injector circuit malfunction?
This is going to depend on where the issue is: Faulty injectors – This will cost between $1,000 and $1,500 if you take it to a shop. If you do the work yourself, it will cost you around $800-$1,000 for the injector parts.
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.
