Why do I get a p0201 code on my injector?
Why do I get a p0201 code on my injector?
Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0201 code when the resistance or voltage drop at the injector 1 is out of specifications. Need more information on how to fix the P0201 code?
What is the diagnostic code for injector circuit malfunction?
P0201 OBD-II Trouble Code: Injector Circuit Malfunction – Cylinder 1. Cost of diagnosing the P0201 code. P0201 is a diagnostic trouble code (DTC) for “Injector Circuit Malfunction – Cylinder 1”.
What does DTC code p0201 stand for?
Diagnostic trouble code (DTC)code P0201 stands for “Cylinder 1 Injector Circuit/Open.” It indicates a potential problem with the #1 Fuel Injector Circuit. Once your vehicle’s powertrain control module (PCM) does not detect the expected voltage spike from the #1 injector, it triggers code P0201.
How to troubleshoot a p0201 circuit malfunction?
The following steps will help you troubleshoot a P0201 code: Perform a visual inspection of the injectors and connections. Many problems can easily be found in the harness and connectors. So, begin your diagnosis by visually inspecting the sensor and its connection. First, check for other codes that would indicate cylinder misfire (P0301 – P0308).
What does p0201 mean on a fuel injector?
It indicates a potential problem with the #1 Fuel Injector Circuit. Once your vehicle’s powertrain control module (PCM) does not detect the expected voltage spike from the #1 injector, it triggers code P0201. Note: The definition of Code P0201 may vary depending on the vehicle manufacturer.
When does the p0201 circuit malfunction cylinder 1?
Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0201 code when the resistance or voltage drop at the injector 1 is out of specifications. Need more information on how to fix the P0201 code? Need more help? What is OBDII? How does the OBDII works?
P0201 OBD-II Trouble Code: Injector Circuit Malfunction – Cylinder 1. Cost of diagnosing the P0201 code. P0201 is a diagnostic trouble code (DTC) for “Injector Circuit Malfunction – Cylinder 1”.
What does p0201 stand for in PCM code?
On the other hand, the peak and hold design allows maximum current to flow just long enough to open the injector. After that, the current is reduced to the amount needed to hold the injector open. The code P0201 stands for Injector 1 – Circuit Malfunction. This means that the PCM had detected a malfunction in the first injector circuit.
What is the trouble code for Injector 1 circuit malfunction?
P0201 – Injector 1 -circuit malfunction Trouble Code Fault Location Probable Cause P0201 Injector 1 -circuit malfunction Wiring, injector, ECM
What to do if OBD-II cylinder 1 injector does not work?
If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.

What causes cylinder 1 fuel injector to malfunction?
Though the most common cause of P0201 is the cylinder 1 fuel injector, it must be properly tested to ensure it is at fault. If the inspection is not done properly, unnecessary repairs may be done, which can waste both time and money.
How do you check continuity between PCM and injector?
You can check for continuity between the PCM and injector using a digital multimeter set to ohms. Touch one end of the meter to the harness side of the injector connector and the other to the injector driver pin on the PCM. An over limit reading (OL) on your meter, indicates there is an open circuit between the injector and PCM.
