This weekend, I experienced the silly symphony of codes and warning lights. "EPS Problem, Hill start problem, brake system problem, brake hold problem, emissions code detected, blood pressure too high, bank account balance too low" etc. You know the ones. The same ones that we almost habitually tell other civic owners "It's your battery" followed by some rehearsed speech about sensitive electronics and voltage swings.
Well, this weekend I had the same symptoms. The only difference is I knew exactly what the problem was when it happened. You see, I was cruising along in traffic when I suddenly heard a change in my engine. I could now hear the turbo. For as nice as that sounded, I certainly lost all feeling of boost. Glancing at my KTuner showed normal target pressures (17 PSI) and almost no actual pressure. I went from a zippy fun grocery getter to a three cylinder Geo Metro with worn out spark plugs instantly. You see, just a few weeks ago, I had all my charge piping apart to drop my transmission. I reasoned that I must've missed a hose clamp and the charge piping came apart.
I pulled over and checked - sure enough, the pipe came apart right before the intake manifold from the hard pipe to the rubber elbow. Sweet! Cheap fix! ... except I didn't have my normal road kit in the car, which meant no tools to tighten the hose clamp. I stuffed the pipe back together and tried to baby the car out of the parking lot, but my efforts were laughable. POP! This time, however, the sudden drop in engine performance caused a series of dings and warning lights to pop up on the dash basically telling me that I had hit the automotive apocalypse.
Neat.
I limped the car home (and boy, I mean limped...) and let it cool off. Now, properly armed with the flat blade screwdriver of truth, I reattached the charge piping and secured the hose clamp. I reset the codes from the Ktuner, cycled the ignition, then went for a test rip. Performance had returned to replace the disco light show on my dash HUD.
The code was P004A. Now, this is interesting to me. Why would the Honda logic send pretty much every control system into limp mode and send a vehicle operator into a panic with such dire warnings over a simple boost control code? I can understand a throttle control code, or brake pressure sensor failure...ya know, things related to the ability to stop and steer the vehicle. Not boost control.
