Full list of the OBD2 DTC from P0700 to P0999

P0442 code means that the control module has detected a small leak in the Evaporative Emission (EVAP). The loose fuel tank filler cap is the most common cause that triggers the P0442 code.

Code P0445 indicates that there is improper purge flow in the EVAP system caused by a shorted purge valve.

Make sure Fuel tank cap is tightened well, then have it tested at Autozone, etc... If ok, then go back to inspection station.

The purge valve is located under the hood on the drivers side fender, the most likely cause of your problem is a cracked emissions hose near the vapor canister. To access the leak detection pump and vapor canister remove drivers side rear wheel and inner splash shield. then remove the metal shield that protects the canister and check all of the hoses.

Sorry dude but you don't have a prayer of a chance to fix this ! You know anything about automotive electronics , electrical systems ? Have a factory or professional scan tool . Going to advance auto won't cut it .

P0442 - Evaporative Emission Control System Leak Detected (small leak)

This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.

Causes: A code P0442 most likely means one or more of the following has happened:
* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* A small leak/hole in a fuel vapor hose/tube
* Other small leak in EVAP system
* Faulty vent o-ring seal

Possible Solutions: with a P0442, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, or
* Inspect the EVAP system for cuts/holes in tubes/hoses



P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted.
Possible Solutions: with a P0445, the most common repair is to:
* Bad or loss contact wires
* Check harnesses, replace it


Hope helps (remember to rate this).

EVAP System leaks---Have a Smoke Machine put on it, and repaired

You told us what it was--small and large leaks

Hi..my name is Keith..and the error code P0442 means...Evaporative emission control system,small leak detected ...and error code P0445 means....Evaporative emission control system,short in purge control valve circuit..i hope this has helped

PO442 means you have a small leak in your EVAP system. Most common cause is a bad gas cap, replace the gas cap with a factory gas cap,after market fail or does not conform to the OEM EVAP system. Other cause would be small leaks in the EVAP vacuum lines. P0445 is also related to the EVAP system and has detected a large leak in the system. Start with the gas cap as mentioned above. P1685 Is an issue with the ignition not recognizing the ignition keys and the car's ignition immobilizer my activate leaving the car not being able to start. That's going to have to be a Dealer repair. Good luck and hope this helps.
