Hello again guys, In cleaning my 2000 Honda CR-V LX’s throttle body, I notice the air intake hose that runs from the throttle body to the filter holder assembly is cut in a couple of places. A $25 replacement hose is available online, so no big deal. Curious though, are a couple of separation cuts/cracks in the hose creating a problem? I’m not noticing a rough idle. It does idle low (around 600/700 rpm). Don’t think this vehicle has a Mass Air Flow sensor, so does some cracking on the hose matter. Would the manifold absolute pressure (MAP) sensor be affected? Thanks guys. Couldn’t figure out the answer doing research. ---

The engine doesn’t use a MAF sensor, so there should be no problem. I would tape the cracks to prevent dirt from entering the engine though. Tester ---

Thanks Tester. Will just do the patch using some hi-temp gasket sealant. ---

Make sure the sealant is sensor safe. Tester ---

Repairing the cracked one will work short time, but I’d replace it, it’ll keep cracking. ---

One caution: Can’t speak to the configuration of your CRV engine, but the version of that hose (really more of a rubber boot) on my Corolla 4afe engine (with MAP, no MAF) has a weird looking empty rubber vessel attached to it. It looks like a lopsided banana. It acts as an air buffer between the air filter and the throttle body. A reservoir of clean air. If the throttle valve is suddenly opened to full throttle it’ll have a supply of air to feed into the engine immediately. This technology has a name, something about resonance as I recall, but whatever it is called, apparently it is important enough to take up considerable space in the engine compartment. The bottom line is that hose should probably be replaced with a new one. Especially if you notice any hesitation, black smoke out the tailpipe, or other symptoms during rapid changes in the throttle position. ---

As always guys, thanks for your time and the advice. Just ordered the new hose should be arriving in a few days. I’ll go ahead and clean out the air filter compartment and put in a new filter (I’m sure it’s due) while I’m at it. ---

Good , $25 is a small price to pay if you plan on keeping the vehicle . It’s obviously there for a good technical reason that the average owner would not know.
