What does open circuit on injector mean?
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. This can help you determine if the injector wiring harness is the cause of the P0200 code and the injector circuit malfunction.
What is a reductant injector?
The reductant injector is used to reduce emissions gases exiting the exhaust by injecting either air or chemicals depending on the usage and vehicle. When the ECU detects the fault in the reductant injector circuit, it will set the P2047 code and the Check Engine Light will be displayed on the dashboard.
Where is the reductant injection valve located?
These heaters are typically located in the DEF reservoir and/or the reductant injector supply hose/s. If the PCM detects no voltage on the control circuit for the reductant injection valve for engine bank one unit one, a code P2047 will be stored and a malfunction indicator lamp may be illuminated.
Is there an open circuit code on the fuel injector?
Hi there. From the description you have provided, your vehicle has an open circuit code on the #3 fuel injector, is going to require circuit testing. The fuel injector (s) are controlled by the injector driver (s) in the ECM (engine control module).
What causes an injector wiring harness to malfunction?
Similar to that an injector wiring harness being open or short and causing the injector circuit malfunction. The injector wiring harness provides power to the injectors and the oxygen sensor, determining how much fuel and air is needed for powering the engine.
Where can I get a Def injector wiring kit?
Injector wiring repair. A repair kit is available from Jaguar Land Rover Parts. You should remove and discard the DEF injector wiring harness aluminium tape and protective sleeve before repairing the DEF injector wiring harness.
What can be done about a fuel injector malfunction?
The diagnosis process of the injector circuit malfunction can be either replacement of the fuel injector, repair or replacement of the connection issues repair or replacement of the wiring issues (like broken wires, frayed wires, cut wires, or shorted wires), and replacement of the powertrain control module.
What causes an injector circuit to be open and not closed?
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.
Similar to that an injector wiring harness being open or short and causing the injector circuit malfunction. The injector wiring harness provides power to the injectors and the oxygen sensor, determining how much fuel and air is needed for powering the engine.
What is the code for an injector circuit malfunction?
The code P0200 is set when the electronic control module detects sensor performance that is out of the range for either the voltage or the resistance within the injector circuit. The ECM can trigger the failsafe mode to prevent any issues in order to prevent damage, and this will continue happening until the error code is fixed.
