    My "check engine" light in my 2004 Honda Accord (4 cyl) came on a
    while ago, and I got Autozone to read the error codes. There were 3,
    and they all seem related:

    P0141 - 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
    P0453 - Evaporative Emission Control System Pressure Sensor High Input
    P2422 - Evaporative Emission (EVAP) System Vent Shut Valve Close

    My guess is one component on the emission side is causing all three
    codes. Does anyone have an idea of what the actual cause could be?

    Some years back I got P0141; I replaced the o2 sensor (the rear one) and
    it went away, never to return. But I didn't get the other two, so I
    don't suppose that would solve your problem. It might be a good place
    to start. It cost me 50-something dollars, and I had to buy a wrench
    for $5 or $6 to remove the sensor itself.

    The first one is totally unrelated to the other two. It means your
    secondary oxygen sensor needs to be replaced.

    The other two have to do with the EVAP system and need to be diagnosed
    properly to determine if in fact they are related to the same component.
    Honda put the EVAP canister under the rear of the car, a strange location
    that exposes the highly-sensitive hardware to water and salt.

    This is because the computer believes that the oxygen sensor indicated
    has an open heating coil. Get an ohmmeter and measure it... if it really
    is open, replace the sensor. Otherwise find the break in the wiring.
    I don't think these have anything to do with the 02 sensor, and my
    suspicion is that it is is clog in one of the EVAP lines or in the
    canister, rather than a break in them. I'd jack up the rear and check
    to make sure all the lines are intact, and I'd check the canister as

    Another thing I've been noticing recently is that when I fill up, the
    gas cap makes a big suction noise when I first take it off. Also,
    while I'm filling up, the fill sensor (or whatever you call it) on the
    nozzle gets triggered about every 2 gallons, even when I start from

    Could that be indicative of a clog in the evap system?

    Thanks again for the help...

    Yes. Check the evap valve. If the car were a decade old, I'd suggest
    just changing the canister and valve sight-unseen, but there's really no
    reason to do that.

    Probably the connector or the wiring to the second O2 sensor has a
    problem. Check the connection first, a little corrosion in there can set

    Both problems are caused by the same item, The EVAP vent solenoid valve
    is stuck closed or the line going to the canister is plugged/kinked.
    That causes a build up of pressure in the tank that sets the 0453 code
    and the stuck valve itself is causing the 2422 code. Replace the valve
    or canister line and that problem will go away.

    I would bet you hear a noise when you open the tank fill as well, that
    is the built up pressure getting out.

    Not related parts. Saying one is causing the other would be like saying
    dropping a hammer on your foot caused the problem.

    Does anyone have an idea of what the actual cause could be?

    what if the fuse for the 02 heater all so runs the evap system???

    Then the other O2 sensor would also be reporting heater problems.
