P2296 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2296 can be elucidated as Fuel Pressure Regulator 2 Control Circuit High. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

1. Engine Control Module - Most of the time it is difficult to intercept the ECM faults and thus must be checked for thoroughly. There can be a problem with the circuit or the software might have malfunctioned. Thus repair, replace or reprogram the component as per requirement.
2. Fuel Tank Pressure Sensor - The fuel tank pressure sensor helps in many ways, most importantly by saving fuel, minimizing environmental pollution, and preventing damage to the engine. The pressure sensor, which is normally positioned inside or on top of the tank, works to detect the pressure in the fuel system, with the end goal of identifying leaks and defective gas caps. Thus, replace faulty sensor now!
3. Powertrain Control Module - If the PCM is faulty, it can stores wrong OBD codes and can lead to misdiagnoses. This can happen due to misinterpretation of data received from the various sensors and components which also affects the vehicle’s performance. Thus replace it immediately.
4. Fuel Injector - Bad fuel injectors can cause starting issues, poor idles and affected performance. Thus, the replacements are in order. Buy new fuel injectors now!
5. Fuel Sender Connector - If the connector is damaged, it should be immediately replaced as it can cause leakages and reduce the power output as well. This will also result in engine lean and rich conditions also. Thus, replace faulty sender connector now!
6. Electronic Control Unit - If the ECU is at fault, it will not be able to read the boost converter temperatures correctly leading to under performance. Thus, replace faulty ECU now!
7. Fuel Pressure Regulator - Without the fuel pressure regulator, the fuel rail will not be able to build up enough pressure to support the injectors with the sufficient amount of fuel, the fuel will instead flow straight through and not reach the injectors. Thus, replace faulty pressure regulator now!
8. Diagnostic Tool - Choose from our diagnostic tools collection that will come handy to detect and correct the OBD error code.

Common Symptoms

• There might be late startup when the engine is cool
• Black smoke might start coming out from the car exhaust
• Diminishing fuel efficiency
• Engine misfire codes and idle control codes might also appear P2296

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• Repair or replace the quirky wiring short to power
• The malfunctioning fuel regulator pressure sensor should be repaired or replaced as per the need
• Carefully adjust the faults in the high pressure pump with the integrated fuel regulator pressure sensor
• The PCM should be restored to working order

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of pcm, ecm, fuel pump, fuel filter, fuel pressure regulator, fuel pressure gauge, engine control module, powertrain control module, pcm car, ecm car, engine control module and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the solenoid itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• On test driving, if the P2296 code does not return soon, he will know that an erratic condition exits.
• But if the error returns instantaneously, he will check every components of the control module as well as the circuit like connectors, wires, harness, fuses etc for any possible fault.
• If any component is damaged, he will fix them right away.
• After performing this repair, he will inspect the fuel pressure regulator as well.
• If there are some faults in the fuel pressure regulator, then it needs to be replaced.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.

Common Mistakes When Diagnosing The P2296 Code

• There are many mechanics that simply clear the ECM memory codes before inspecting the freeze frame data for the main failure problem, so the failure may be duplicated and repaired.
• Sometimes the mechanics do not follow the manufacturer pinpoint tests for the application.
• A lot of mechanics simply assume that the regulator sensor is faulty and replace it, but in reality the real issue is with some other part.
