Have a code of po453 but my pump dose not have the sensor


Hello,

I just looked the the code up. Code is an EVAP code, Evaporative pressure sensor which is part of the emission system. The ECM is seeing high input reading and this is usually because the sensor harness is disconnected or the senor is defective.


I hope this help.

Po453 code for 1998 gmc sierra


P0453 - Fuel Tank Pressure (FTP) Sensor Circuit High Voltage-this usually means the vent solenoid is defective and needs replacement, but I would clear the code with a scanner (or disconnect the negative battery cable for five minutes) and see if it comes back-often this is set by:

  • Open on FTP sensor signal wire
  • Short to voltage on FTP sensor signal wire
  • Bad FTP sensor
  • Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank
  • Loose/damaged FTP sensor connector
  • Loss of ground to the sensor

Codes po452 and po453


both codes point to the fuel tank evap pressure sensor. High and low input faults.
Try clearing the codes first and seeing if they come back

You may have a vacuum leak, cracked or open vacuum line or faulty sensor.
