Nissan Rogue: Too high Fuel Tank Pressure Sensor/Switch

Nissan Rogue employs an evaporative exhaust control system (EVAP) to move fuel vapors out of the tank and neck. They are then sent to the engine to burn off.  If the pressure in the fuel tank becomes too high, P0453The check engine light turns on when a, is thrown.

Your Rogue will not fail if the sole trouble code you have is P0453.  The EVAP system controls the movement of fuel vapor.  The EVAP system's ability to move fuel vapor has no bearing on your engine's performance.  This code is not to be ignored.

The EVAP isn't always functioning.  It uses a  valve to open and close the system to release fuel vapor into the engine to be burned off.

This sensor detects if the fuel tank pressure is too high.  It measures the air pressure inside the tank and not the fuel pressure.  When it does, the P0453 signal is sent.  The fuel tank pressure sensor can be found on top of the fuel tank, fuel pump or fuel level sending device.

The opposite of this code is P0452, which is thrown whenever the system pressure is too low.

P0453 Symptoms:  Nissan Rogue

P0453 Check Engine

There are usually no symptoms that can be associated with the code.  The check engine light will illuminate (that’s why you’re here).

One thing you might notice is the fuel smell.  If the EVAP isn't working properly to remove the fuel vapor from the air, the system will look for other routes.


There are many causes

These are some of the most common reasons for P0453.

  • Charcoal canister Clogged vent valve
  • Pressure sensor in fuel tank damaged (sensor, or the wiring)
  • Tank with contaminated fuel
  • PCM/ECM (highly unlikely)

Diagnostics for P0453 Nissan Rogue

Diagnosing P0453 in your Rogue can be challenging if you don’t have a scan tool that is capable of reading the fuel pressure sensor data or capable of commanding the vent valve to open and close.

 

How to Make Your Home a Better Place

  • If you happen to notice the sound of air escaping when you take your Rogue’s gas cap off, that is a telltale sign that the vent valve is bad, or the charcoal canister is bad(it’s pressure leaving the gas tank).  Once you have driven for some time, turn off the gas cap and go somewhere else.  It’s hard to notice the sound when you’re at a noisy gas station.
  • You should check the wiring for the fuel tank pressure sensor to see if there are any frayed wires.  If it isn’t then the only way to really diagnose it is with a professional mechanic’s scanner.  It can be difficult to look at the tank without dropping it.

How a mechanic will do it

  • The data of the fuel pressure sensor will be captured by a mechanic to determine whether it detects any vacuum.
  • You can also tell the vent valves to open or close.  You can also hear the engine running depending on your vehicle's year.

 

A mechanic can inspect the wiring leading to the fuel pressure sensor if the fuel tank pressure is not within the specifications.  The fuel pressure sensor must be replaced if it is not working as expected.

The charcoal canister must be replaced if the vent valve turns on and the pressure sensor works fine.  If the vent valve doesn’t come on, it will need replacement in order to clear P0453.

If all appears to be in order, it could indicate that the PCM may not work properly.


Nissan Rogue: P0453 Conclusion

That’s pretty much it.  While there are only a couple of common things that’ll cause P0453, there it can be tough to diagnose it without the right equipment.  It’s not going to leave you stranded on the side of the road either.  Good luck fixing your Rogue!
