The P2291 fault code in automobiles indicates a problem with the Injector Control Pressure (ICP) sensor. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty ICP sensor, an open or shorted ICP sensor harness, or a poor electrical connection in the ICP sensor circuit.
The importance of repairing this issue lies in the fact that it can lead to poor engine performance and fuel economy. The repair difficulty is moderate, and the repair time is estimated to be around 1.0 hour. To fix this issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.Repair Importance Level 10.0 (Out of 10) Estimated Repair Time Approximately 1.0 hour Repair Difficulty Level 10.0 (Out of 10)

P2291: Affordable Fix For Complex Fuel Pressure Issue
The fault code P2291 indicates a problem with the fuel pressure regulator. The diagnosis involves checking the fuel pressure sensor, fuel pump, and fuel filter. The estimated repair time for this fault code is 1.0 hour.
The fixing cost will depend on the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.
Other factors that may affect the cost include the severity of the problem, the type of vehicle, and the location of the repair shop.
P2291: Fuel Pressure Regulator 2 Performance – What You Need To Know
The P2291 code is related to the Injector Control Pressure (ICP) sensor.
The Powertrain Control Module (PCM) monitors the ICP sensor and sets the code when the signal is out of factory specifications.
The ICP sensor is a variable capacitance sensor that produces a linear analog voltage signal indicating pressure. The code indicates that the engine cranking is experiencing injector control pressure that is too low.
The ICP sensor’s primary function is to provide a feedback signal to indicate rail pressure so that the PCM can command the correct injector timing and pulse width.
The correct injection control pressure is necessary for proper fuel delivery at all speed and load conditions.
