Question about 2004 Jaguar X-Type

1 Answer

I have a 2004 Jaguar evap control system leak, codes P0445 nd Po447. I have replaced the Gas cap, but light keeps coming on. my Actron tester can send a command to test the evap system,but I don't know what to do when it is in test mode, am I supposed to wait for a code? Or am I to go and inspect the car for leaks or leaking sounds. Any idea how long the test lasts for? Any help would be appreciated. Thanks

If your wanting to know what to check. po445 is the purge solenoid control circuit, po447is the evap vent solenoid control circuit.Check the connections, and the wiring for shorts, or replace solenoid. Could also be a failed pcm.

P0445 on my 2003 hyundai tiburon Gt evap


This code's description is P0455 Evap Emission System- Large Leak. Usually ,arge leak means you drove or still driving your vehicle with loose or missing gas cap. Check your gas cap if it is tight. Even if that is the case , tightening it might not turn the check engine light off. So you have to erase the code with a scanner. If your gas cap is in place and tight then you probably have a leak in the emission system which includes numerous parts. So it should be inspected by a proffesional.

Engine code po455


Check this info about P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. 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 p0455 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)
Other leak or damaged piece in EVAP system

Possible Solutions: With a p0455, 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, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary


Check it and keep us updated.

My check engine light came on and it is a p0442 EVAP SYS, small leak


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.

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

The check engine light keeps coming on -we were told it was because gas cap was loose-but she filled up & tightened the cap-but still on


First, you need to go to a local parts store and find out what the code means. If it shows a small leak, the gas cap probably needs replaced. Gas caps need replaced more often now that computers register fuel emissions.

Engine codes for 2001 Chrysler Sebring P0442 455 and 1685


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.

P0455 comes back on ,we try to fix it


The EVAP control sytem is checked by the ECM upon the first start of the day when the engine is cool and will trigger the DTC code P0445. If you have a vacuum line leak when it's cold and seals it self when it warms up then the code will stay there. After warming up the car reset the ECM to clear any DTC codes and see if any MILL shows up. IF not then there is a leak only when the system is cold so your going to have to try to do a smoke test when the system is cold.
The other thing is to check all the vacuum lines and fittings around the canister and fuel tank for any lose clamps ECT.
Good luck and keep me posted. Be glad to help you
