Fuel Press Regulator 2 Control Circuit High
P2296 is an OBD-II code for the engine control module (ECM) detecting the number 2 fuel pressure regulator control circuit is high indicating a high return voltage.
The Check Engine Light will be illuminated and the code is set in ECM memory as a fault.
The engine may run normal if the pressures are normal and rich if the pressure is too high.
The engine may run lean if the fuel pressures are below specified range.
The sensor may part of the low pressure side of the system.
Scans for codes and documents the code in the ECM, and then looks at the freeze frame data for failure
Follows the manufacture pinpoint test procedures and specifications for checking fuel pressures
Follows the manufacture pinpoint testing for the fuel pressure regulator code received (there may be different testing between manufactures)
Checks fuel pressure at specified engine RPM levels and compares to specifications using a gauge
Compares test readings with a gauge to the sensor readings for the fuel pressure regulator
Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired
Failing to follow the manufacturer pinpoint tests for the application
Replacing the regulator sensor without verifying the failure assuming the part is the failure
Code P2296 indicates that the engine ECM is detecting the fuel pressure regulator is shorted to power and can cause the fuel system to run higher or lower than needed causing running problems.
Replacing the high pressure pump with the integrated fuel regulator pressure sensor
Repairing wiring short to power
Code P2296 is most commonly caused by a fuel pressure regulator sensor. Some vehicles have a separate replaceable sensor and others have sensors integrated into the high pressure fuel pump. The entire pump will need to be replaced to fix these vehicles.
