If you got that code from an auto parts store (for free ) they can give you a print out of trouble shoting tips you have more then the gas cap to check. gas cap is the most commen culprit.you have a rubber line to the purge tank and a rubber line from the tank to the egr valve and a rubber line from the egr valve to the throttle body they are the second most commen cause of leaks also the valve could be shot its not supposed to open durring idle if that when your light pops on could be the problem

P0442 I got the check engine light in my GMC savana 2008 I get this code P0442 it said. a small leak in detected can someone please help me with this problem I reset the code 2 times already the first time...


The P0442 code is for a small leak in the pressurized emission system. It can be caused from something as simple as not tightening the fuel cap all of the way after fueling, or a leaky seal at the gas cap, or a leaky o-ring around a number of sensors and fittings in the emission system. If you are sure that you are tightening the fuel cap all of the way, and have already replaced the fuel cap and see no nicks on the seal on the fuel cap or fuel neck, you might need to have the vehicle hooked up to a smoke machine to try and find where the leak is coming from.

2004 pontiac sunfine 0442


Smoke test the system . P0442 small leak .
This DTC tests the evaporative emission (EVAP) system for a small leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the vacuum decay rate. At an appropriate time, the control module turns the EVAP canister purge solenoid valve ON and the EVAP vent solenoid valve ON. This allows the engine to draw a vacuum on the EVAP system. At a calibrated time, or vacuum level, the control module turns the EVAP canister purge solenoid valve OFF, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum decay. If the control module detects a leak larger than a calibrated amount, this DTC sets.

What is an error code p0442 for a 2001 seabring mean?


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

P0457 which is the gas cap is loose or off.

This means that there may be a leak in the hoses that lead from the gas tank to the charcoal canister, if so equipped.

Good luck on finding the leak and repairing.
