This code indicates a leak in the evap system. The first thing to check is the gas cap-is it on tight? If yes, check vacuum hoses under the hood. A loose or degraded hose on the purge valve will also cause this code. The purge valve looks like the pic below and has one hose going to the engine and the other going to the vapor cannister.

2004 Honda Pilot Evap code P1456 Changed gas cap from honda and still


code p1456 refers to evaporative emission (EVAP) canister purge system(fuel tank system) -leak detected===causes--hose-fuel tank/pressure sensor--fuel filler cap--EVAP valve /bypass solenoid--EVAP two way valve---EVAP canister/vent valve

There is also a second reference to the code which is EVAP system leakage ====filler cap--EVAP canister purge valve--hoses---EVAP canister shut off valve---ECM programming---ECM

Check with the service dealer that the filler caps are interchangeable . It may be coincidence that the problem started after you changed caps or it may have shown a failure in the making

P1457 HONDA - Evaporative Emissions Control System Leakage EVAP Canister Systemxicon.jpghttp://engine-codes.com/p1457_honda.htmlForum CodePossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap There is a Honda factory service bulletin with information on how to diagnose the P1456 on the following Honda models:
1998 Honda Accord
1999 Honda Accord
2000 Honda Accord
1998-2000 Honda Accord
symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 HONDA Description The evaporative emission (EVAP) control system stores fuel vapor from the fuel tank in the EVAP canister temporarily to prevent it from escaping to the atmosphere and to enable it to be drawn into the engine by intake manifold vacuum and burned. In addition, the onboard refueling vapor recovery system (ORVR) stores fuel vapor generated when refueling in the EVAP canister.

The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs. The P1457 code is detected when the EVAP system has a very small leak.

P0107 HONDA - Manifold Absolute Pressure Sensor Circuit Low Voltagexicon.jpghttp://engine-codes.com/p0107_honda.htmlForum CodePossible causes- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Engine Control Module (ECM) When is the code detected?An excessively low voltage from the sensor is sent to ECMSymptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 HONDA Description The Manifold Absolute Pressure sensor provides instantaneous manifold pressure information to the engine's Engine Control Module. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.


In some vehicles the absolute pressure sensor is built into ECM.

I have honda odyssey and the service engin coms on and the cod is p1456 so ineed to figur out thanks.


This probably means:
  • P1456: Evaporative Emission Control System Leak Detected (Fuel Tank System)
  • Usually this is because your gas cap was not fully tightened. Be sure to turn it until you hear a click.
  • After you tighten the cap, it might take a couple days of driving before the light goes-out.
  • Be careful to tighten your gas cap regularly, because otherwise it puts a heavy strain on your emission system.

My car turns off when i start slowing down or when im pressing on the break, i tested it and it gave me 2 numbers a P1491 and a P1456 my car is a 99 honda accord ex, a 4 door.


P1491 = Exhaust Gas Recirculation (EGR) Valve insufficient lift.

P1456 = Evaporative emissions (EVAP) control system leakage (fuel tank system).

Check the EGR valve for a failed vacuum diaphragm. Check the fuel filler cap to make sure it is the correct factory style, has a good check valve and is on tight.

P1456


code P1456 set when there's small leak in the fuel tank system.
Most known reason for P1456:
-Didn't tight fuel cap on until it click for more that 3 time after fueling up and drove the car too long with cap loose.
-or a bad gas cap.
I'll try tighting the gas cap.
clear check engine.
if code come back, replace gas cap and clear check engine light again.

P1456 code on a 1998 Honda Accord. Gas cap was checked out ok. Any other suggestions?


P1456 EVAP CONTROL SYSTEM LEAKAGE ( FUEL TANK SYSTEM)

There are a lot of potential leak points. The canister could be leaking, any number of the system hoses could leak. You could even have a leak in the fuel tank. Do you ever smell fresh gas?

I have a 01 honda accord 2.3l it has a obd fault code p1456, can any one tell me what this code means?


smal evap leak detected....very common check your fuel cap make sure it't tightened at least three clicks-check the o-ring of the cap as this will
cause a leak as well. drive vehicle the code will clear it's self if it odes not go away after 1 week of continuos driving it may have a larger leak
in this case you need to see a dealership-they will perform evap function test and determine if problem is worse-1457 is the bad one indicates large leak and can be expensive,. hope this helps.
