I have a 2002 Honda Civic sedan with 94K miles on it. Yesterday the engine malfunction light came on. I consulted the owner‘s manual and it said to first check the gas fill cap. I did that and re-tightened it, but the light did not go out. Then it added that if that didn‘t fix the problem it was likely something wrong with the emission system. I wanted to know if the engine malfunction light on would have created a code that can be read and if that is the same thing as check engine light on other cars. I called the auto dealer today and they said they charge $100 just to check the code and depending what it is, if they could even fix it or would have the parts, if needed. Someone at work suggested I take it to Advance Auto since they will check the codes for free. Any other advice would be appreciated. Thanks.
Two companies make the flexible pipe, they are QEST and PEX. I prefer PEX because you crimp the pipe on with a brass ring and it is guaranteed not to freeze bust or break for 100 yrs. QEST uses slide on hand tighten fittings, and they may or may not work well. I just don't trust something that is hand tightened to stay tightened when the pipe expands from heating and shrinks from cooling I prefer the crimped brass ring, then I know it is not going to leak. Either works very well when repairing older galvanized pipe. Just cut the galvanized pipe, unscrew it from the joint one both ends, screw in a Pex fitting, slide a brass ring over the pex pipe and slide the pipe onto the fitting and crimp it. Unroll the pipe to the other end, cut it, slide a brass ring on it, slide the pipe onto the fitting on that end and crimp the ring.
Personally would replace with copper as plastic does not look as good and the fittings are too bulky, als the plastic fittings rely on the rubber o ring inside them which after 10 or so years tend to dry out and perish causing small leaks which if pipe work is in awkward places or hidden can cause big problems later.
Yes to the subject question. That light means THERE IS A PROBLEM with either engine performance and/or emission controls and should be repaired ASAP. This light DOES set codes in the computer and can be scanned with an OBD2 scan tool. Most auto parts stores will do this as a free service.
The check engine light will only be lit while the conditions are present to warrant an error. In other words, conditions went back to acceptable for some reason. If the check engine light came one for an entire tank of gas I'd think about using a different gas station. Bad gas can really screw your engine up. The code will still be stored in the computer and in most cars it can even tell you what the engine was doing when the code appeared. i.e. what speed traveled, what gear, any other contributing factors, etc.
1 any auto parts store will check engin lite/malfunctionfor FREEdealer is a rip off SOB. 2 hows it running? if no tune up in 80K its past due wires too not just plugs 3 fuel filter? throw in a can of fuel injector cleaner just for fun. 4 flush cooling system as recomended? change oil on time?
