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.

P0455 and p0442


p0455-- emission control system ( a large leak ) the most common cause is a bad seal on fuel cap, remove and replace cap, if light stats on. replace cap. if not the cap it could be any where in emission system. p0442 is--same as above. Code p0442 indicates a fuel vapor leak in the EVAP control system. To fix this problem, remove and reinstall the gas cap. Clear the codes and drive to see if the codes reappear. If the code appears again replace the gas cap or inspect the system for cuts or holes in the tube or hose. good-day !
