What is the P2293 fault code? What does it all mean?
Fault code P2293 means that the fuel pressure regulator has stopped working. This code is issued when the powertrain control module, PCM detects an increase in fuel pressure beyond the allowed threshold.
The function of the fuel regulator is to maintain the fuel pressure at the right level and return excess fuel to the tank. Some vehicles have it built into their fuel rail assembly. The regulator is built into the fuel pump. The PCM controls the operating speed and fuel pressure of these fuel pumps. The PCM controls the speed and demand for fuel. It increases speed when more fuel is required, while it decreases speed when less fuel is needed. The open time of the injectors determines how much fuel is injected into the cylinders.
A P2293 code will be triggered when the PCM detects a problem with the fuel pressure regulator and the fuel pressure is not in compliance with specifications (high or lower).
Note: Depending on the vehicle manufacturer, the definition of P2293 malfunction code may vary. The vehicle’s repair manual, or the database containing the information, will provide a detailed description of the code.
Vehicles susceptible to the P2293 fault code include but aren’t limited to certain models of Volkswagen, Audi and Nissan, Chevrolets, Opels, Seat, Mercedes-Benz and Renault.
What causes the P2293 Fault code?
Here are some reasons why P2293 should be set.
- – Corroded, burnt, damaged, shorted and disconnected wiring.
- – Defective fuel pump
- – Defective fuel pressure regulator
- – Fuel filter blocked
- Leaky fuel injector
- – Defective fuel pressure sensor
- – Fuel lines that are blocked or restricted
- Vacuum hoses that are damaged or lost in designs where the pressure regulator can be vacuum operated
What are the symptoms of the P2293 Fault code?
You may experience the following symptoms if your vehicle has the code P2293:
- – Illumination for the check engine light
- – Increased fuel use
- – Reduced engine performance
- – Engine hesitation during acceleration
- – Engine stalling and stalling
- – The engine might not start or run well.
- Fluctuations of engine speed
- – O2 sensor fault codes relating to lean mixture can also be adjusted
How do I fix the P2293 fault code?
The following repairs may be able to resolve the P2293 fault code:
- – Repairing damaged cables, connectors and open or short circuit issues
- – Replace the fuel filter
- – Replacing a faulty fuel pressure regulator
- Repair of bent, restricted fuel lines because they are clogged or blocked by impurities or for other reasons
- – Replacing a faulty fuel pump
- – Replacing a faulty fuel pressure sensor
