    Could you tell me what they want to replace? That does seem rather steep, but would have to see the estimate first.

Code po456 on a 2006 mustang 6 cylinder. any suggestions?

P0456 - Evaporative Emission System Leak Detected (Very Small Leak)
The powertrain control module (PCM) monitors the complete evaporative emission (EVAP)
control system for the presence of a very small fuel vapor leak. The system failure occurs when a fuel vapor leak from an opening as small as 0.508 mm (0.020 inch) is detected by
the EVAP running loss monitor test.
Possible Causes:
• Very small holes or cuts in the fuel vapor hoses/tubes
• Loose fuel vapor hose/tube connections to the EVAP system components
• EVAP system component seals leaking. See the Possible Causes for DTC P0442
Diagnostic Aids:
Check for a missing fuel filler cap or the integrity of the cap.
Check for loose or damaged vapor hoses. Visually inspect the EVAP canister inlet port, CV solenoid filter, and canister vent hose assembly for contamination or debris.

How do you detect evap leak problem in a 2002 dodge neon

You need what is called an Evap Smoke Machine
only a repair shop would have,to find the leaks

Without Evap System knowledge & a Schematic
of the system components ,you can not personally do anything

What does PO 455 code mean on a 2002 Chrysler Sebring?


This simply means that your Evaporative Emissions Leak Detector monitor has detected a large leak in your Evaporative Emissions (EVAP) system.

It is common for this code to set if you refuel your vehicle with the engine running, forget to put the fuel cap back on after refueling, or do not properly install or tighten the fuel cap after refueling. In these cases, it can be fixed by simply installing the cap properly and clearing the code. Also, make sure your engine is turned off when refueling so it dos not happen again.

If none of the above is the cause of this code, then you either have a large leak in one of the hoses, connections, or the fuel tank itself, or the EVAP leak detection pump is defective.

What does check engine code P-0455 and P-1684 mean?

P1684 - Battery Disconnected Within Last 50 Starts

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

Test and check it. Hope this helps.

PO456 code on 2002 Jeep Wrangler.Where do I start?

p0456 is ayoun evap fault honestly this is a job for a professional with the correct diagnostic equipment jsut from memory it is a vent control fault. if you have access to alldata or mitchel on demand you can get diagnostic steps for the proper diagnosis. unless you have the proper tools this is a job left to a good repair technician that you trust sorry i cant give you a straight answer but you will throw away money buy just replacing parts and hoping it fixes it, just food for thought if the code is cleared it will take time to come back the only way to conferm the repair is a evap self test that can be done with the adiquite scan tool

Eng lite stay on test show 455 424

P0424....Heated Catalyst Temperature Below Threshold (Bank 1)

P0455....Evaporative Emission Control System Leak Detected (gross leak)

I would start with clearing the codes and see if they come back. That is the first step of diagnosis.

Some Chrysler products you can clear the code by turning the ignition on and off three times and then starting the engine. If you still get the 455 you will need to find a shop that has a smoke machine to find the leak. It is very difficult to find a leak in an evap system.

Hope this helps

2002 chrysler neon error code p0456

a small evap leak is often interpreted as a loose gas cap , which it can be , it means the evap systems integrity has been breached , it can be an electrical solenoid , switch or just a vacuum line in the system . a bidirectional scanner can run the evap test after checking the gas cap , most well equipped shops can hook up a smoke machine to the evap system service port and run the smoke test , it there is a leak you will see the smoke , makes the diagnosis quickly . get an estimate from a reputable shop , by the way this problem has no effect on drivability , but should be fixed . cheers
