Trouble code P0442 means:Evaporative emission control system leak detected (Small leak)
P0442: Evaporative Emission System Leak Detected (small leak) P0455: EVAP Large Leak Detected
Trouble code P0442 means: EVAP System Small Leak (0.040") Detected
Trouble code P0442 means: EVAP System Small Leak (0.040") Detected
Small evap leak.
You have a small EVAP leak, possibly a loose or faulty fuel cap.
small evap leak, check the fuel cap, if it is not loose, replace it.
You have a small "EVAP" leak. Start with replacing the fuel cap.
Trouble code P0449 means: EVAP Vent Solenoid Control Circuit Malfunction
Code P0442 is a small leak in the Vaporative Emissions or EVAP system. Common problem. Few places to check - rubber hose under air box (requires removing the airbox) and hoses connecting to evap system under the van on the drivers side. Good luck.
EVAP Emission control system leak (small). It could be as simple as a loose fuel cap.
p0442 - Evaporative emission control system, small leak detected. Check fuel cap, make sure it clicks when tighten. I'm working on a 2000 Taurus. P0442 EVAP Control System Small Leak Detected Possible Causes Setting Conditions * Aftermarket EVAP parts that do not conform to specifications * CV solenoid stays partially open when commanded to close * EVAP component seals leaking (i.e., leaks in the Purge valve, fuel vapor control valve tube assembly or fuel vapor vent valve) * Fuel filler cap damaged, cross-threaded or loosely installed * Loose fuel vapor hose/tube connections to EVAP components * Small holes or cuts in fuel vapor hoses or EVAP canister tubes Cold engine startup (ECT sensor less than 90�F), engine running in closed loop at a steady cruise speed, and the PCM detected a leak in the EVAP system as small as 0.040" in the EVAP Monitor test. This code sets in 2 Trip(s).
The evap control valve is on the cannister
