More then likely its the Canister Purge Solenoid. you can find it online at www.autozone.com the part number is PV140. And to replace it on blazer you have to remove the spare tire. Alot of people don't know where this part is so I hope this helps you and good luck.

What does code t0440 mean on a 2003 malibu


Do you mean "P0440"?

Diagnostic Test Code (DTC) P0440 has a generic description of "Evaporative Emissions System Large Leak".

The MOST COMMON cause of this code is refueling the vehicle with the engine running or not getting the fuel cap on correctly after refueling.

The Powertrain Control Module (PCM) checks for leaks in the Evaporative Emissions (EVAP) system using the data provided by the Fuel Tank Pressure (FTP) sensor. It will check the FTP sensor data, then close the EVAP Vent Valve and open the Canister Purge Valve to apply vacuum to the EVAP system. After a period of time, the PCM will again check the FTP data to see if the fuel tank pressure has dropped within a specified amount. If there is very little or no change in the FTP data, DTC P0440 sets.

Other possible causes for this code are:

> Defective FTP sensor (VERY RARE)
> EVAP Vent valve stuck open
> Canister Purge Valve stuck closed
> Large leaks or cracks in any of the EVAP system hoses and/or lines and/or components, including the fuel tank and the fuel filler neck and the EVAP canister

Please note that this code indicates a MECHANICAL failure of the system. This is NOT a circuit fault that would involve broken/shorted wires, blown fuses, etc..

  • Inspect the EVAP system for cuts/holes in tubes/hoses
  • Inspect for damaged or disconnected hoses around the Evap purge solenoid
  • Check and/or replace the sensor

Check Engine Light won't go off


If you have an Advance Auto Parts store where ever you are, they will read the code and tell you exactly what to code is and what it means. Any mechanic who "guesses" isn't a mechanic at all - he's a thief. Emissions leak can be any number of things, but not the gas cap!

Obd code p0440 for check engine light on 2000 Toyota Corolla


p0440 code means that the evap system has a leak. This could be caused by a bad or improperly installed gas cap. Either that or the purge solenoid has failed or the canister is plugged and not working properly.
