Guide To P0292 OBD Error Code Solutions

<<See All OBD Codes

The OBD error code P0292 is generated when the Fuel Injector circuit in the cylinder 11 is not conforming with the manufacturer’s reference value.

The Engine control module (ECM) turns the fuel injector on and off while it’s in normal working condition. In case of error, the moment the voltage drops or rises by 10% of the manufacturer’s reference value, the error code P0292 gets stored. The OBD code P0292 is generated when the cylinder 11’s Fuel injector circuit is not in line with the prescribed values. This might be due to malfunctioning injector circuit or loose connections. The error might be occurring due to issues with one or more parts of your vehicle. Once the error has been detected and the pain point has been revealed, you must immediately repair/replace the part or parts causing the problems.

The conditions in which the error code is generated:

• Fuel Injector 11 is dirty
• Fuel Injector 11 is faulty
• Fuel Injector 11 is clogged
• Harness of the Fuel Injector 11 is open or shorted
• Fuel Injector 11 circuit has a bad electrical connection

1. Fuel Injector - The ECM sends a signal to the fuel injector to spray the pressurised fuel into the engine. If there is an issue with the Fuel Injector itself, the amount of fuel delivered might vary from the optimum or prescribed values which might create problems with the engine or emission system. Thus, it is necessary the fuel injector is repaired or replaced, as required, urgently.
2. Fuel Injection System - An engine needs to be supplied with the right amount of fuel/air mixture for the vehicle to work smoothly. Due to an issue with the Fuel Injection system, the amount of fuel delivered to the engine might vary from the prescribed values or the balance of quantities between the fuel and air might not be in concurrence with the limits required for an efficient emission.
3. Connector - The Fuel Injection Connectors are used for making connections between the incoming current to the Fuel Injector and the ECM. The problems with Fuel Injector Connectors usually go undiagnosed and lead to repairs of costlier parts without the actual problem getting solved. The connectors can be replaced at very cheap prices and thus if the error code is being generated, it might be wise to have a look at the connectors early on so that the problem can be solved easily.
4. Wiring - The Fuel Injection Wiring or the Fuel Injection Harness includes the wiring of the fuel injector. If the wiring is faulty, it might be leading to short circuiting or variations in the amount of current flowing to the injection system. Fixing the wiring is a tedious job since it requires looking very minutely to any rust or cracks in the wiring or harness.
5. Powertrain Control Module - The PCM is one of the most important components in the control system of a vehicle. It controls over a hundred factors in a vehicle. The PCM is commonly referred to as ‘The Brain’ of the engine control system. Thus, being pivotal in the operations of a vehicle, it is extremely necessary that even the slightest fault in the PCM must be immediately rectified.
6. Fuel Injection Control Module - Fuel Injection control module is a pattern failure that leads to the vehicle not starting or being difficult to start. When failure occurs, the engine might operate roughly when it’s cold. Basically, the fuel injection control module sends an electrical impulse to the fuel injector so as to deliver the required quantity of fuel to the engine cylinder at the moment it’s required. Since FICM is a very essential part for the engine’s performance and fuel economy, it is necessary to keep it in good working condition and thus, in case of any issues, it must be repaired or replaced immediately.

When there are problems in the Fuel Injector circuit of cylinder 11, there might be symptoms that could show before the error code is diagnosed. The Check Engine Light might be on and stay on. While driving, the engine might feel rough when it’s running and it might misfire at some point. You might also notice lowered mileage per gallon. Since it is problematic to drive the vehicle in these conditions, it is necessary to get the vehicle checked for error codes and have them fixed.

Once the mechanic has used his/her scanner to deduce the code and has tested the vehicle, they might use some of the following repairs to fix the error code P0292:

• Flushing the Fuel injector is one of the simpler solutions
• Checking the wirings and connectors and make repairs or replacements as needed
• Replacing the Fuel Injector

For diagnosing the error code P0292, a mechanic will use an OBD-II scanner to get more information about the vehicle. He/she will hook the scanner to the vehicle’s on-board computer and gather data from the vehicle. He will thus use this data for diagnosing the problem and determining the best course of action. The mechanic will reset the code and test the vehicle to see if the code returns. This will filter out the possibility of false alarms since some older vehicles might show error codes that aren’t actually caused by issues in the vehicle.

Common Mistakes When Diagnosing the P0292 Code

A common mistake during the diagnosis of the error code that can be made is to replace the injector immediately. Usually, it might be that the injector is only clogged or even partially clogged and an injector flush could be a simpler solution instead of replacing the entire injector. Thus, a thorough diagnosis is required before reaching to any conclusions
