I just had a scan done on my 2000 grand am 2.4 engine it had a code po442 where is this located on the car and I heard gas tank needs dropped to replace


I heard gas tank needs dropped to replace ???? You should never listen to what you heard from someone who has no clue ! P0442 is a small leak DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected. You really should take it to a qualified repair shop .

EVAP Leaks P0442 and P0455

The evaporative emission system is tested by applying vacuum to the EVAP system and monitoring for a vacuum decay. The PCM monitors the vacuum level through the fuel tank pressure sensor signal. At an appropriate time, the EVAP canister purge solenoid valve and the EVAP vent solenoid are turned on, allowing the engine to draw a small vacuum on the entire evaporative emission system. Once the desired vacuum level has been achieved, the EVAP canister purge solenoid valve turns off, sealing the system. A small leak in the system will cause DTC P0442 to set.

P0442 check engine light code


The computer that read the code for you can also reset it.  If you don't have one, you can go to your local auto parts store and have them reset it for you.  This is what your code means P0442 Evaporative Emission Control System Leak Detected (small leak).  This is what Causes it and possible fixes: CausesA code P0442 most likely means one or more of the following has happened:
  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • A small leak/hole in a fuel vapor hose/tube
  • Other small leak in EVAP system
  • Faulty vent o-ring seal
Possible SolutionsWith a P0442, the most common repair is to:
  • Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
  • Otherwise, replace the gas cap, or
  • Inspect the EVAP system for cuts/holes in tubes/hoses
