What causes injector circuit low?
What causes this problem with the Cylinder 1 Injector Circuit Low? The wiring or connector which is related with the number 1 cylinder could be having or causing a connection issue and connection issues may also cause voltage levels to decrease or become inaccurate.
How do you fix a low injector circuit?
What repairs can fix the P0261 code?
- Replacing the fuel injector on the number 1 cylinder.
- Repairing or replacing wiring or connectors that are associated with the fuel injector on the number 1 cylinder.
- Replacing the powertrain control module.
How do you fix an injector on a open cylinder 1?
Possible fixes include:
- Replacement of the Cylinder 1 Fuel Injector.
- Repair or replacement of any wiring issues (damaged or broken wires)
- Fixing poor connections.
- Replacement of the PCM.
What causes fuel injector circuit open?
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. Similar to that an injector wiring harness being open or short and causing the injector circuit malfunction.
Why is my cylinder 1 injector low code?
This code implies that the powertrain control module (PCM) has experienced a low voltage situation involving the fuel injector for the #1 cylinder in the firing order. In short, this fuel injector is malfunctioning for one of a variety of reasons. It is important to diagnose and repair this type of problem as soon as possible.
Why does my injector have a low voltage?
This sensor is an oxygen sensor, and the low voltage is often an indication that the injector’s spray pattern has changed and the #2 cylinder’s fuel mixture is too lean. The symptoms arising from too lean of a fuel mixture can vary in their characteristics as well as in their intensity.
What causes a high reading on the injector sensor?
Code P0265 is caused by high, rather than low reading of the #2 cylinder fuel injector sensor, and indicates the fuel mixture is too rich. Its symptoms are much the same as the P0264 symptoms, but the cause is usually different.
How to test the injector solenoid on a C13 engine?
F. Perform the Injector Solenoid Test at least two times. Result: All cylinders indicate a -5 code on Cat ET. The harness between the ECM and the connector does not have a short circuit.Proceed to Test Step 5. Result: One or more cylinders indicate a -6 code on Cat ET.
