Hi all- I just bought a 98 Accord LX sedan last weekend, driving around a few days ago the CEL came on. I went to Autozone to get the code readout and it gave the P1457 code. Of course the guys at autozone said it was just the gas cap, which according to my service manual and research on here would more likely throw the 1456 code instead. I reset the ECM and the CEL stayed off for a couple days but came back on again this morning. I had an appointment scheduled with the local Honda dealer this morning anyway to get a throttle bleed screw adjustment so I figured I'd go ahead and mention the code to them. Even the service tech up there said it was most likely the gas cap!
So after I got home I decided to pull out the service manual and read up on the test procedures. The first test was a vacuum test on the PCV solenoid hose. It did not hold vacuum so the manual said it was OK, proceed to the next step which was to check continuity between the 2pin solenoid plug and ground. With the A6 terminal on the ECM wiring harness plug jumpered to ground per the manual, I tested the #2 pin connector (red/yellow wire) for continuity and got zilch.
So a couple questions- 1. Please confirm I did this test correctly? (A6 terminal on ECM wiring harness jumpered to ground, ignition key off, multimeter connected between 2pin (red/ yellow wire) on solenoid wire plug and ground, no continuity readout.)
2. If this test was correct and I showed no continuity, it appears I have a break in that red/yellow wire between the ECM plug and the solenoid plug. Does anyone have any clue how expensive that would be labor-wise to get fixed? (That must be a nightmare of a wiring job.)
3. Is it possible to confirm this is the problem by routing a secondary wire between the ECM plug A6 connector and the #2 pin connector on the solenoid plug, then seeing if the CEL comes back on? (TBH I actually have one in place as we speak.)
Thanks all

Anyone?
My main concern (other than whether I did the test wrong) is that running a secondary wire might somehow screw up the ECM- any input would be appreciated. Thx

I suggest you get a honda service manual for your vehicle. You want the service manual used by the honda dealers - a little pricey but worth it.

BTW - To do electric diagnostic work on the large machines I sell and install - I have a Fluke multimeter and this thing measures from millivolts to 110/220/440 both dc and ac. This thing has revealed multiple problems with power supplies in very large hospitals. Pricey - over $500 but safe and accurate. Probably are chinese knockoffs avail for a lot less.

Check autozone and on line for replacement switches.

Good luck

I already fixed this months ago, thanks to posting it in another site (6th Gen Accord) since this site is a joke for responses. Someone there informed me that replacing the evaporator canister attached to the gas tank would solve the problem, and I didn't have to wait a year for a response that helps in no way.
I also already have the Honda service manual.
