Question about Honda Civic

1 Answer

I have a 02 civic si, engine is a k20a3, I have a check engine light that comes on when I'm going home up a mountain that I travel on. The trouble code reads manufacturer control air/fuel metering and doesn't let the engine go past 4,000 rpm. I've notice when it's getting ready to come on that I hear a sparking sound coming somewhere from the car before it comes on. Where is the problem causing this so I can get it fixed without spending 90 dollars to have a dianogstic done.

The fuel air mixture is controled by the car's computer with information it gets from the oxygen sensor and several other sensors measuring air temperature, manifold pressure outside air pressure, air flow into the engine, throttle position and others.

I could bet, the most influential of these is the oxygen sensor that is located in the exhaust pipe on the passenger's side just behind the engine, changing it is very easy and could bring your car's fuel economy back to what it should be.

    Also, I can heard that this is a common problem with the VTEC systems, the car revs up to about 3500 or 4000rpm, and then
    it just starts revving the engine really high but the cars moving at
    the same speed,
    it could just be the solenoid itself restricting oil flow at engagement point. One Honda owners tell that found out had blown head gasket and chip block and all this good stuff.

    Too, the Mass Air Flow sensor could be malfuncting causing bad O2 sensor readings also. When the owners really make to check the sensors, find answer like this (quote)...
    I failed a PA emmissions test with the following codes:


    P1166 Primary HO2S (No. 1) Heater System Electrical

    P1167 Primary HO2S (No. 1) Heater System


    I'm dirt poor at the moment so replacing the O2 sensor (at $220+) was
    the last thing i wanted to replace. I tested the circuit and fuses, but
    everything looked ok. I called the dealer a few times to see if they
    can give any advice, but they weren't much help (go figure)
    I finally talked to and a local, reputable diag place and the old
    timer told me that its probably the sensor since they go bad around 60k
    miles anyway. I bought one from AutoZone for $245, rented their socket
    and installed it in about 2 minutes. About 2 miles later the light was
    off! wooooooo!


    Good luck.

    I have replaced the O2 sensor and nothing happen. Couple miles later it came back on. I finally got some advice from the dealership and they said that it's either the filter screen for the vtec or the vtec soleniod itself, but was told to check and clean that screen before buying the vtec soleniod. I pulled the vtec body off and sure enough the screen was totally stopped up. I could barely see any light come through it. So far so good. The check engine light hasn't came on.

'03 Civic Si 5 speed k20a3 Having trouble shifting at higher rps. Shifter resist moving into next gear. Clutch grabs as it should and there are no hydraulic leaks or malfunctions.


Expect that the clutch is dragging. The plate may be warped maintaining a spin on the transmission input putting an excessive wear on the synchronizers.

Inspect clutch.
Inspect pilot bearing

Hope this helps.

Check engine light


A computer scan of the car should point you to the problem in the cruise control, or whatever it is. When the engine light goes on, it should store a trouble code. Many national parts stores do free scans for trouble codes.

In 97 mercury mountaineer, how to turn off "check engine" light


Go to the local parts store, have them check the codes (they will do this for free usually). It will tell you what sensor needs to be checked/replaced. Once the part is replaced, it will clear on its own. They can also reset the code, but it will come back if the trouble persists.

My check engine want come on at all do u know why


That check engine light should come on, as soon as you turn the key on, then when you start the car, it should go out, my guess is, either someone has removed the lamp, or it's burned out.

Does 2001 buick century check engine come on for any other reason other than problems with engine. seams to be running great


the light comes on for faults in the engine fuel control system and for the emission control system on the car, about 150 different trouble codes that can turn the light on. If u would like a free test for these trouble codes go to any Kragen or Autozone parts tore and they will do the OBD2 trouble code test.
