Environmental psychology addresses environmental problems such as density and crowding, noise pollution, sub-standard living, and urban decay. 1  Noise increases environmental stress.
Hayapower is correct. The tube from the converter is for the smog pump (air injection) for the catalytic converter. The EGR tube comes off the passenger side exhaust manifold. Disconnecting the tube from the converter will not hurt if you remove the conveter and close off the tube end or leave it open.If you leave it open then at times you will hear a pumping sound from the tube caused by the smog pump when it reaches proper temperature.t's thermactor/secondary fresh air injected from the smog air pump for converter/catalyst secondary burn/conversion.. Disabling/restricting an EGR flow (drastically), can/will result in a DTC.. The tube is needed for a fresh air suppy to the converter..
The fuel pump is inside the fuel tank. They rarely fail on Honda, check the more common (and easier) problems first. Check the fuse. Check the main fuel pump relay, which is â¦ located under the dash on the passenger side of the steering column. Step #1: Do not crank the engine, but turn the key on.The fuel pump should run for 2 seconds and shut off automatically. Listen for the very slight hum it makes. If you can hear it hum for two seconds and then shut off, the pump is probably fine.he fuel pump is in the gas tank (left side) If you lift the tank, you will see a rectangular panel on the inside left side.
