What to do if your fuel tank pressure sensor is faulty?
It also proves that the fuel tank pressure sensor is faulty, replace the sensor. Finally, if your sensor value is stuck somehwere else between 0 and 5 volts, make sure you’re not building too much pressure nside the tank due to a faulty fuel cap, or EVAP vent valve. That’s it for the Fuel Tank Pressure Sensor Quick-Fix. Loading…
What is the Check Engine Light code on a gas tank pressure sensor?
This fuel tank pressure sensor article covers a boatload of General Motors cars and trucks. These automobiles will set a check engine light code in the P0440 range. However, when the sensor itself causes a problem, P0452 or a P0453 set for the fuel tank pressure reads low or high respectively.
What should the voltage be on a fuel tank sensor?
The voltage should never read zero or 5 V. Instead the reading should be somewhere in between those high and low points. The voltage should also change when the engine is first started. If you do find a fixed voltage reading between zero and 5 V you most likely have a defective sensor.
Why does my pressure sensor keep setting p0452?
Although the pressure sensor is often the cause of a P0452 or P0453 there are other possible causes. Breaks in the signal wire or the ground connection will also cause these two codes to set. So lets talk about verifying if this part needs replacing.
Can a fuel rail pressure sensor be changed?
The fuel pressure sensor is a weak link in the fuel system and many complain that they have had problems with it. It can give up due to high temperatures. Many are wondering if they need to change the high-pressure rail along with the sensor. The answer is no. Only the sensor is changed and the repair takes less than 15 minutes.
What kind of sensor is a fuel gauge?
The fuel pressure sensor is a resistive strain gauge sensor. The operation of this type of sensor is based on the piezoresistive effect: the electrical resistance of a conductor varies depending on the longitudinal mechanical deformation.
