What does the p0442 OBD-II trouble code mean?
The P0442 generally has no adverse symptoms other than the Check Engine Light being present. When this code is seen, it means that the EVAP system is leaking fuel vapors into the atmosphere. A slight dip in fuel economy may be noticed with this code. What repairs can fix the P0442 code?
What to do if you find a p0442 gas leak?
If you see a P0442 evaporative emission system leak detected code, you may be able to resolve the problem without much effort. The easiest solution may be to remove and reaffix the gas cap. Once you do, clear the code on the OBD-II diagnostic scanner and drive for a few days. If the code does not return, your gas cap likely was the culprit.
What does the po442 code on a car mean?
The PO442 indicates that there’s a small leak in the EVAP system. When the vehicle engine is turned off, the Electronic Control Unit (ECM) carries out a leak test to double-check that the evaporative emission control system is functioning correctly. In this test, the ECM seals the EVAP system.
