One of the worst problems that can happen to a vehicle is a bad fuel pump. Without gas your Enclave will not run at all. With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all. While being in the fuel tank makes the pump more reliable, it also makes it a lot more difficult to get to.

The good news is that fuel pumps are inexpensive. The bad news is that they cost a lot in terms of labor to repair and replace. The engine may throw a P trouble code. Any trouble codes that exist could be a clue.

Sometimes when there is low fuel pressure, you may also get an oxygen sensor related trouble code as well. The real issue with diagnosing a bad fuel pump is that it resembles many other vehicular issues in terms of symptoms. One of the most common signs that a fuel pump is going bad is a whining sound. The whining sound can indicate that the fuel pump is going out before there are any performance based issues.

Keeping an open ear can save you from getting stuck somewhere with a bad fuel pump. Typically, if you are heading up a hill or accelerating the engine may start to feel like it is just running out of steam. Now, a bad fuel pump can also feel a heck of a lot like a bad catalytic converter. Both conditions will make the motor feel like it is running out of wind when you hit the gas.

A bad catalytic converter will not feel as jarring. If you are unsure, check out this article on troubleshooting catalytic converters. If you get P or P trouble codes with a scanner, it very well may be the catalytic converter causing these symptoms. One of the best indicators of a clogged fuel pump is going to be that the your Enclave is difficult to start.This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. The power control module PCM regulates the amount of fuel that is released into the combustion chambers by controlling the fuel injectors. This process works to reduce tailpipe emissions. In order to work effectively, the power control module must always know what the fuel pressure is.

If the fuel rail pressure sensor is giving inconsistent readings, the power control module PCM will store the P trouble code. The mechanic will use the OBD-II scanner to retrieve the freeze frame data to find out what the condition of the vehicle was when trouble code P was set by the power control module PCM. Completes a test drive and uses the live data to determine whether the fuel pressure reading is normal.

Uses a fuel pressure tester to make a determination as to whether there is a sensor problem or a fuel pressure problem. If the fuel pressure is normal, they will use an oscilloscope to test the connector and wiring of the fuel rail pressure sensor. A common mistake when diagnosing the P trouble code is overlooking the other components that may need to be repaired and replacing the fuel rail pressure sensor first.

Wiring that is insufficiently connected or chafed, a faulty fuel pressure regulator or faulty fuel pump are things that are often missed when doing a diagnosis and completing a repair. The P trouble code is considered serious as it is known to cause drivability issues. Operating a vehicle while this code is present could cause the car to stall out or hesitate while driving.

There may also be an increase in fuel consumption, which can be costly. It is important to take this code seriously and have it diagnosed and repaired as soon as possible. Most of the time, there are other components that cause this trouble code. Take your time and consider all of the possibilities before concluding that the fuel rail pressure sensor is faulty. Also, make sure you have the proper tools necessary for diagnosis. YourMechanic offers certified mechanics who will come to your home or office to diagnose and repair your vehicle.

There are two fuel system pressure sensors in your application: one on the fuel rail and the other on the fuel feed pipe forward of the fuel tank. The fuel rail pressure sensor detects fuel pressure within the fuel rail.

The ECM receives a varying signal voltage on the signal circuit: when the fuel pressure is high, the signal voltage is high. When the fuel pressure is low, the signal voltage is low. This sensor receives power and ground from the fuel pump flow control module.

When the CD player is in use and gives you the Heat Error warning, then the CD player is operating at too high of a temperature. Turn off the audio system, and give the CD player sufficient time to cool RPMs go up and down Hello. Your car is equipped with a computer-controlled transmission, so a scanner should be connected, the system checked for codes, and the data analyzed.The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases.

The varying resistance affects the voltage drop across the sensor terminals and provides electrical signal to the Powertrain Control Module PCM corresponding to pressure. Strain gauge type sensors are consider passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.

Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor. The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each combustion cylinder.
