2003 Honda Accord LX: engine compartment fuse box..drivers side

Resolved Question:

I believe I have a vacuum leak on my 2003 Honda Accord LX. I cannot locate it exactly. But it originates from somewhere beneath the engine compartment fuse box, which is on the drivers side behind the battery. I get a sucking sound from this location when I press the accellerator and a whoosh when I turn the car off . Is there a vacuum accumulator underneath this area that might be the source of the problem? The code is 2227. However, I have checked and cleaned the TPS and made the code disappear. But the air-loss sound persists. I think the computer is periodically interpreting the air loss as a TPS problem. Any ideas? (Thanks HONDASERVICE7791 for your previous resonse.)

HelloCustomerand welcome again to,


Have you checked the line to the Brake vacuum booster which is located on the firewall directly back from the fuse box?

I have checked the brake vacuum booster; but I am not familiar with the location of the "line." How can I locate it?

Is this a vacuum line?

Is this a vacuum line? The old brake boosters used to have a vacuum line connected to a big diaphram. This new design is different. I am not familiar with it. So I need more guidance.

here's a picture of the vacuum line, follow it from the booster to the intake and check for leaks
