What does the DTC code p0442 stand for?
Diagnostic trouble code (DTC) P0442 stands for “Evaporative Emission Control System Leak Detected (Small Leak)”. Your car’s computer will set the code when it determines there’s a minor leak somewhere in the evaporative emission control (EVAP) system. A P0442 code indicates that there is a minor leak in your vehicle’s EVAP system.
What does the DTC code p0122 stand for?
Diagnostic Trouble Code (DTC) P0122 stands for “Throttle Position Sensor/Switch A Circuit Low Input.” The powertrain control module (PCM) logs a P0122 code when the throttle position sensor “A” displays lower voltage than normal. As its name implies, the throttle position sensor keeps track of the throttle’s position.
Why does my OBD-II detect a p0442 leak?
If you see a P0442 DTC, you know there is a fuel vapor leak somewhere in the EVAP system. The small leak code tells you that the leak is probably minor. If your OBD-II diagnostic scanner registers a P0442 DTC, you must find and repair an EVAP system leak. Here are some common reasons you may see this code:
What does small leak code mean on OBD-II?
The small leak code tells you that the leak is probably minor. If your OBD-II diagnostic scanner registers a P0442 DTC, you must find and repair an EVAP system leak. Here are some common reasons you may see this code: Now that you understand the possible causes of this DTC, you need to know how to fix the problem.

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.
