Not only that, if the fuel pressure sensor is faulty, it may output too little information to the ECU, which in turn may increase the amount of fuel being fed into the engine. He has been working as a car mechanic for over 10 years, and the majority of them specialized in advanced car diagnostics and troubleshooting. Toyota Corolla L4-1.6L - Fuel System Inspection - Sacramento, California. Injuries, electric shocks, burns and other life threatening hazards can be a result of an inappropriate action on the engine. See further information here. The power control module (PCM) regulates the amount of fuel that is released into the combustion chambers by controlling the fuel injectors. However, precautions are to be made, while checking the output using an oscilloscope. Improper supply of fuel to the engine will cause an unexpected stall. The FRP sensor nominal output varies between 0.5 and 4.5 volts, with 0.5 volts corresponding to 0 MPa (0 psi) gauge and 4.5 volts corresponding to 26 MPa (3771 psi) gauge. I would suggest a few more checks first. This can also cause damages to your engine in the long term. Chosen Solution I have a 2007 FORD FOCUS 2.0 and according to Smog Check station it didn't pass.

On most engines, the fuel rail is somewhere on its intake side. Stalling. The following P-codes (DTCs) are OBD II failure codes and generic to all OBD II compatible cars and could appear, if your fuel rail pressure sensor is faulty. The amount of fuel injected into the engine during combustion is determined by two factors how long the fuel injector stays opened and at which pressure the fuel gets injected. I say no voltage but i checked it with a test light. I have checked the wire from the PCM to the connector at the FRPs and its ok. Back probed the wire to the PCM, no voltage. The check engine light is an indication that something is going wrong in your engine that needs immediate attention. If the fuel rail pressure sensor is giving inconsistent readings, the power control module (PCM) will store the P0191 trouble code. My fuel pump is new. If the fuel rail sensor malfunctions, it sends incorrect information to the ECU, which changes the settings, causing the fuel supply to be inadvertently interrupted, and your car takes longer to start. Service Agreement Program What Is It & Is It Legit? This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Check the wirings visually for any noticeable damages. Simply put, it sends this data to the ECU, which changes fuel pressure and injection timing as required.
