    My 2005 Pontiac Bonneville's "Service Engine Soon" light came on. A garage checked it out with computer and put on a new gas cap. Two weeks later, the same light comes back on.

2002 GMC SONOMA CODE P 0442


Code 442 is a common code for a small leak in the EVAP system. The computer vents the gas tank to the vapor canister when the engine is running. The computer checks for leaks also.
The EVAP system would need to be checked for leaks.

Code 0442 dodge caravan 2005. What could it mean?


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.

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


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

Hope helps.

Have OBD codes P2A00, P0441, P0442, P0446 on my 2003 Highlander. Selling the car in a few months. Does this really need to be repaired before trade-in? Can I just erase the codes?


NOPE CANT ERASE CODES UNTIL THE PROBLEM IS FIXED OR THE SERVICE ENGINE LIGHT SOON WILL STAY ON. CODE PO441 - EVAPORATIVE EMISSION EVAP SYSTEM INCORRECT FLOW DETECTED.CHECK INTAKE VACUUM HOSE CONNECTIONS AT THE EVAP CANISTER PURGE VALVE.IF ALL IS GOOD.THE EVAP CANISTER PURGE VALVE COULD BE BAD. CODE PO 442 - EVAPORATIVE EMISSION EVAP SYSTEM SMALL LEAK DETECTED. EVAPORATIVE EMISSION SYSTEM LARGE LEAK DETECTED FUEL CAP LOOSE OR OFF MISSING. CODE PO 446 - EVAPORATIVE EMISSION EVAP SYSTEM VENT CONTROL CIRCUIT MALFUNCTION.

1998 Cheverolet Lumina, ''service engine soon'' and hard gear shift


I doubt the two problems are connected. I would try a new gas cap and see what happens since it runs fine. The service engine soon light won't reset on it's own right away.
