Why is there a pressure sensor on my fuel tank?
There are a few important reasons: The fuel tank pressure sensor does all this by monitoring the pressure, both positive and negative, inside your fuel tank. This sensor is an integral part of your car’s evaporative emissions system, also known as EVAP.
What is the Check Engine Light code on a gas tank?
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. Unfortunately, if the seal fails where the sensor fits into the fuel tank it can also set evaporative emission system leak codes like P0442.
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.
What does 5 V mean on a pressure sensor?
If you do find a fixed voltage reading between zero and 5 V you most likely have a defective sensor. If you don’t have an automotive scanner you’ll have to lower the tank and pull the connector off the pressure sensor and test it with a voltmeter. If the voltage reading is either zero or five then it’s possible that you have a wiring problem.
