Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / September 2007Honda Accord 98 Check Engine Light coming repeatedly
I have a Honda Accord 98. Recently I have got the Check Engine Light on. I read the Haynes manual and tried to get the error code from the PCM which turned out to be "80" (using the blinking light method in the dashboard). I interpreted the code (from the Haynes Manual) as a leak near the fuel Canister. I thought that the problem occured with not tightening the fuel cap, so went ahead and tightened it real good. After a couple of days, the light went off. Again after a couple of more days (with me not touching the fuel cap), the light came back on again. So now the problem is it comes and goes from time to time with the same error code. Any ideas on what could be the issue ? Do you think that I have a faulty fuel gas Cap ? Or am I interpreting the error code totally wrong ? PS: It is Winter here and the temperature are around 50 deg farenheit... Regards, John Edwards Virginia, US. >I have a Honda Accord 98.

No, 80 is Exhaust Gas Recirculation, insufficient flow detected See http://tech.hybridgarage.com/tech/codes.html Typo in previous post, the error code is 90. Try looking in the area of the charcoal filled vapor collection canister. Could be that it's contaminated with raw (liquid) fuel, or plugged in some manner. > I have a Honda Accord 98.

I had the same problem with my 98 Accord V-6. It was an intermittent control module located near the charcoal cannister. Some kind of solenoid, a black cube about 2" on a side. Had some hoses connected to it. Cost me $40 for the part. Parts guy told me they go often, because of their exposed location (under rear passenger, driver's side). You can probably replace this yourself, but you'll have to remove the charcoal cannister to get at it. I can get you the exact name of this part from my Honda manual tomorrow, maybe even the part number from the sales slip. Probably called a purge valve. Allows vapors collected in canister while engine off to be rerouted to engine at start-up. > I had the same problem with my 98 Accord V-6.

Here are the exact details: The Honda manual calls this an EVAP Control Canister Vent Shut Valve. The sales slip indicates part# 17310-SOX-A02 and describes it as W-valve. The thing mounts on the end of the canister facing the frame rail under the read driver's side door. It's the upper of the two similar-looking pods, hence the need to remove the canister to get at it. It has one large hose, and one electrical connector. It mounts to the canister with two phillips screws. In my case I removed it, applied 12 V from a DC wall hugger, and heard the solenoid activating and deactivating as I made or broke contact. I put it back on the car, cleared the code, and everything was fine for two weeks. Then the light came back on. I bought the new valve and installed it in March 03, and haven't had a problem since. > Probably called a purge valve.

Mike, thanks for the detailed description. Just curious, did you get the same code 90 from the PCM ? -- John Edwards Yes. > Thanks for all the replies. Mike, thanks for the detailed description. > Just curious, did you get the same code 90 from the PCM ? > -- John Edwards Update on this topic. I have replaced the Canister shut off valve as suggested by rufovillo... I have reset the check engine light. It is been a couple of days, the light has not yet come back. I have driven the vehicle atleast 5~6 times for atleast a distance of 80 miles. I am not sure what Honda manual means when it says that "the light will come on when the sensor detects the problem in three consecutive drive cycles" I am not sure what a drive cycle is, but atleast I have driven the car 5 times, if that counts then the problem has been resolved. BTW, if anyone is following this thread, to remove the canister shut off valve, we need to remove the canister itself as specified in the earlier posts by others. One thing to add is, there is only one bolt that holds the canister to the frame. I had by mistake tried to remove the frame itself which has three bolts. Once the canister is out, replacing the vavle is easy, except that the two philips screws that hold the valve to the canister are very tight ( I wonder why Honda does not have a bolt instead of the screws !!! ) In my experience, when I try to remove the screws, the threads on the screw almost always get ripped off, I wonder why they don't have bolts instead !! -- John I also got the code p1457 on my Honda Accord, it was the purge vavle back next to the charcoal cannister which is located back underneath the vehicle on the drivers side rear tire area. There are a few hoses attached to the cannister and purge vavle, and 1 bolt that holds the cannister in place. The purge vavle is held in place with 2 phillips head screws which you have to soak with penetrating oil and then get a pair of vise grips on them to loosen them up. This repair is a very easy repair for a decent home mechanic, and it will save you a bundle of money too. You have to reset the code after you are done, remove the negative side cable from the battery and the light will go out. Then you must drive about 16 miles in order for the parameters of the computer to straighten out, your car may stall at idle in that period till you achieve the proper distance of driving. I payed $44 for the part, its not a easy part to find, but its online. I now have over 600 miles since the repair and the check engine light is still out. >Here are the exact details: The Honda manual calls this an EVAP >Control Canister Vent Shut Valve.

Now, my car 98 accord got the light on at the first the autozone give me a code P1456. So, I clear the light off and drive for a week light come back on. Then, I buy new gas cap from dealer but light was still on. I let dealer check for me, they said there is only 1 leak that they could found is gas cap, so they reset form me. Now for 6 days the light come back on what should I do?? >I also got the code p1457 on my Honda Accord, it was the purge vavle back >next to the charcoal cannister which is located back underneath the vehicle [quoted text clipped - 16 lines] >>> > name of this part from my Honda manual tomorrow, maybe even the part >>> > number from the sales slip. |
