RE: Why Am I Hard Starting? - 12/6/2006 4:29:50 PM    JohnnyWadd   Posts: 42 Joined: 1/12/2006 Status: offline It was suggested to me that I disconnent my battery, then wait for the CEL to come on again, since I was getting such a scatter-brained response from my car. I took the advice, and thus far, the 12 and the 22 code have not returned. That made sense, as I forgot about something. Right after I got the car running, I took it for a test drive, and one of the vacuum lines popped off. I hooked it back up, then it decided to come off again. Turns out the speaker from my alarm was rattling against it and making it come loose. So, I moved the speaker and those two codes have not returned. So, when the CEL came on and I crossed the plug, the only code it is showing now is a 9, which is the #1 Cylinder Position Sensor (CYP). Can't lie to you guys. I don't know anything about this one. Can anybody lend any help? First off, where in the heck is it located? I'll check the plug and all that, but does anybody have any idea how to check this sensor? I thank you in advance for any help that you can give. Jon (in reply to deserthonda) Post #: 46

CYP sensor is located in the distributor. You can check for loose connections in the wiring harness plug at the distributor. I don't have wiring drawing for your year, so I don't know which wire. The CYP sensor is not available separately (AFAIK) - you have to buy a new distributor. So try to rule out simple wiring problems first. You can measure it's resistance but I don't remember what it should read. If resistance is OK, the sensor may still be bad. It's a magnetoresistive sensor where the only true complete test is to watch it's signal with an oscilloscope. < Message edited by JimBlake -- 12/7/2006 7:15:08 PM > _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to JohnnyWadd) Post #: 48

I ran into a huge expenditure on the girlfriends car, so I decided to move my problems to the back burner. The car is running okay, so I haven't really been that worried about it. Not sure if that's a stupid idea on my part or what. Anyway, let me give you a quick update before I go. I did disconnect the battery to reset the ECU and waited for the CEL to kick on again. This time I only got the code 9 (the CYP sensor for cylinder 1 at TDC). I rechecked a while later and still only the 9 code. The others must have appeared when the vacuum line popped off. I've had no more vacuum line problems and the other codes have not returned. As I said before, the problem only shows up every once in a while (curiously, only when I'm iding and usually at a stoplight in gear, never at highway speeds). It doesn't make the car run worse, near as I can tell, so I haven't been overly worried about it. It'll idle down for a sec, the CEL will pop on, then the idle will return to normal. I tried to find something on the distributor disconnected, but couldn't find anything. I'm going to try to look into it a little more when I get my other stuff fixed, and also when the weather starts to cooperate a little bit more. Thanks for your input. Jon P.S. Ever since winter set in here in Nebraska, I'm really glad I replaced that head gasket. None of the problems have come back and the car is running tip top. I thank you all for help with the diagnosis. I'd be miserable this winter if I hadn't fixed that. (in reply to JimBlake) Post #: 49
