The diagnostic trouble code P0201 tells us the ECM has detected a malfunction with the cylinder 1 injector circuit. This code indicates out-of-range performance was detected in the operation of cylinder 1 injector circuit. Once a malfunction is detected, a Check Engine Light is triggered and failsafe mode is enabled.
What would cause a P0201 code?
P0201 code 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. Once your vehicle’s powertrain control module (PCM) does not detect the expected voltage spike from the #1 injector, it triggers code P0201.
What causes fuel injector circuit open?
This error code refers to a condition where there is too high or too low voltage or a resistance drop at the injectors. In sequential fuel injection, the PCM controls each injector individually. Each injector receives battery voltage from the power distribution center (PDC) or other fused source.
How do you fix P0204?
What repairs can fix the P0204 code?

P0204: What It Means
A P0207 code means that the PCM has stored a trouble code indicating poor performance on a fuel injector on Cylinder 4. This could be due to a bad injector, an open or short connection, an intermittent open or short, a bad ground or even a bad PCM (though rare).
How do I fix P0201?
What repairs can fix the P0201 code?

- Fixing poor connection faults.
Can you drive with code P0201?
If your vehicle is in limp-in mode, you may have a top speed that’s limited to about 40 mph or less. Chances are that if you have a P0201 OBD-II trouble code, your vehicle will be running poorly enough that it won’t be very driveable.
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.
What is the code for a faulty fuel injector?
The most common fault codes associated with a clogged fuel injector are P0171 and P0174, which indicates the engine controller is seeing a lean condition. It is also possible to see fault codes for a rich condition if the injector is leaking or not atomizing correctly.
How do you check injectors?
Keep the engine running and touch the end of a long metal screwdriver against the fuel injector. Put your ear on the opposite end of the screwdriver. A clicking sound means the injector’s working. Silence means the injector may need to be cleaned or replaced.
How do you clean Fuel Injectors?
Zitat von Youtube: So thank you just go to your local auto parts store and get a rubber hose that's the same size. And you just slide it on this end of the fuel.
What does injector circuit low mean?
This trouble code indicates that the powertrain control module has detected a lower reference voltage coming from the number 1 cylinder’s fuel injector than what was specified by the vehicle manufacturer.
