SOURCE: Check engine light is on. EVAP small leak

You need to check the purge and vent solenoids for proper operation. You need to check the pressure sensor for out of range ( defective ). You need to check the filler neck for cracks and make sure the clamps are tight. You need to check the vapor lines for loose fit. I've seen at the charcoal cannister where the lines connect it may not be on strait. A smok test will reveal this if its not sealing. You may have a leaking rollover valve or fuel pump seal on top of the tank. You may just have a vacuum leak under the hood, These trucks have an Evap management valve also that can be leaking or out of specs. Look on the emmisions lable or vacuum chart under the hood. This will show you the underhood components.

It is probably a sensor that goes by the gas tank. I belive it is called a Fuel Vent Sensor Circuit. That should fix the problem.

your problem is probably a vacuum hose that goes from the purge valve to the gas tank (crack or broken hose). There should be two of these check both. A broken vacuum line will make the purge valve make a clicking noise that can be mistaken for noisy engine valves.

Code is for a small evap leak in my experience with Subaru it's caused by the filler neck on the gas tank being rotted at least in New York were I'm from. If you live were there is no rust my advice is to start with a gas cap or have the vech smoke tested

P0457


Code 457 means the computer has found a small 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 most common cause is a faulty gas cap, but it could be a hose or something else. The gas tank has to be pressurized to look for the leak.

Chevy s10 2002 p0302, p0457


code p0302 refers to cylinder 2 misfire detected===causes --engine mechanical fault--wiring---ignition/fuel system---injector--ECT/MAF sensor---ECM
code p0457 refers to evaporative emission system--leak detected (fuel cap loose/off) ==causes --mechanical fault--hose connections---EVAP pressure sensor
Replace faulty items. Use only genuine items as replacement
as non-genuine are not always compatible with the OEM fitted CPU units. This results in the fault codes not cancelling out. If possible you may be able to get the CPU reset to work with the non genuine items you already have.

Error code 340 & 457


  • P0340 - Camshaft position sensor circuit malfunction.
  • P0457 - Evaporative emission control system leak detected (fuel filler cap loose/off)

    There is a bulletin #0398 posted on 05/12/2003 for P0457 - Malfunction indicator lamp (mil) illumination with diagnostic trouble codes p0442, p0455, p0456, p0457, p1442 or check fuel cap lamp illuminated with diagnostic trouble code p0457.

I'd suggest checking with your local dealer, as it may be a fix that is covered by the dealer.

Obd code p0457 fuel cap replaced mil reset defect not cleared connection checked ok


The code is for a large leak in the EVAP system such as a loose or missing gas cap. But it could also mean a loose or missing hose to the canister or other leak in the tank.
The computer vents the tank several times an hour while the engine is running, and it checks the system by pressurizing the gas tank. If the tank will not hold pressure the code is set.
You may have to check the top of the tank where the fuel pump gasket is, as well as the vent lines to the front of the car.
A mechanic would perform a smoke test to look for leaks.

An error code of 0457 came up. any idea what that is?


P0457 FORD - EVAP Control System Leak Detected (Fuel Filler Cap Loose/Off)
EVAP control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly.

Vehicles that meet enhanced evaporative requirements utilize a vacuum-based evaporative system integrity check. The evap system integrity check uses a Fuel Tank Pressure Transducer (FTPT), a Canister Vent Solenoid (CVS) and Fuel Level Input (FLI) along with the Vapor Management Valve (VMV) or Electric Vapor Management Valve (EVMV) to find 0.040" diameter or larger evap system leaks. Federal vehicles can utilize a 0.040" leak check rather than the 0.020" leak check required for California vehicles (click over pic for zoom).
