SOURCE: 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

SOURCE: Code P0456 on 2003 Town & Country

Below are the possible causes for your engine light and error code:

Possible Causes:

  • EVAP fuel tank or canister vapor hoses leaking or damaged
  • EVAP system component leaking, fuel cap loose or missing
  • Leak detection pump damaged or leaking

The fuel cap is probably the most common cause of this problem. It's considered part of the emission system and if faulty or not place on the filler tube correctly, it will throw an error. Best of luck with your engine light issue. Take care!

P0456: Evaporative Emission System Leak Detected (small leak)

Using a Multimeter, check the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80 terminals 1 and 2 for resistance. You should get 22.0 to 30.0 Ohms. If not, replace the canister. If you do, you have other problems.

Trouble Code Conditions:
EVAP vent valve stuck open: EVAP leak check pressure is lower than -0.14 kPa even if EVAP vent valve is operated from OFF (OPEN) to ON (CLOSE) with EVAP leak detection pump ON. EVAP vent valve stuck closed: EVAP leak check pressure is unstable (difference between maximum and minimum is 0.36 kPa or more) when EVAP vent valve is OFF (OPEN) with EVAP leak detection pump ON. EVAP leak detection pump stuck OFF: EVAP leak check pressure is higher than -0.14 kPa even if EVAP leak detection pump is ON. EVAP leak detection pump flow high: Reference pressure of EVAP leak check pressure is lower than specified value (depending on BARO) EVAP leak detection pump flow Low: Reference pressure of EVAP leak check pressure is higher than specified value (depending on BARO).

Code po456 what is the problem


The generic description for code 456 is a small or large leak in the EVAP system. The computer vents the gas tank to the vapor canister when the engine is running. It also checks the system for leaks.
The gas tank would need to be pressure tested for leaks, including the gas cap.

Engine light stays on code # P0456


P0456 is Evaporative Emissions System - Small leak detected.

More often than not it is a gas cap that is either not put on corrert or it has failed to hold the seal.
Less likely causes are:
  • A small leak in any of the EVAP hoses or fuel tank hoses
  • A small leak in the purge valve or vent valve
  • The EVAP Canister may be leaking

Engine light shows a code P0456 (small evap leak) on 2005 Grand Caravan. Replaced gas cap but engine light stays on.


It is likely a leaky hose in the evap system. The chemicals passing through the hose cause it to become brittle, causing cracking. Take a look at this instruction to see if it helps:

P0449 and P0455 error code 2008 2wd gmc envoy 30,203 miles


P0449 - Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction

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

Both are refer at EVAP system; other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456

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: 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: 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


Hope helps.

replace your gas cap and clear codes, then wait and see if light comes back on, if it does you have a more serious problem like a fuel tank leak or a defective fuel tank pressure sensor.
