What does the p0442 code on a Kia mean?
The P0442 code means that the control module has detected a small leak in the Evaporative Emission (EVAP). Loose fuel tank filler cap is the most common cause that triggers the P0442 code. The cost of diagnosing the P0442 KIA code is 1.0 hour of labor.
What causes an EVAP leak in a Kia?
P0442 Kia Description The Engine Control Module (ECM) tests the Evaporative Emission (EVAP) system for the following conditions: – Large and small leaks – Excess vacuum – Purge flow during non-commanded conditions – Fuel Level and Fuel Pressure sensor faults – EVAP Purge and Vent Valve faults
When does the EVAP system detect a leak?
Malfunction is detected when EVAP control system has a leak, EVAP control system does not operate properly. The ECM monitors the Fuel Tank Pressure sensor in order to determine the level of vacuum/pressure in the EVAP system.

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.

Failures of each input and output device are indicated and retrieved from the engine control module (ECM) as diagnostic trouble codes.
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.
