FourString Posted December 23, 2013 Report Share Posted December 23, 2013 I got caught in the monsoon the other day, and the check engine light came on. The car developed a very quick stutter only when coming back on-throttle. Aside of that, it ran fine. I scanned it at both O'Reilly and Advance to find code P1392. This code comes back to Cylinder Position Sensor according to the database. I pulled the battery cable and let it reset. The car drove like nothing was wrong during the initial drive after. I shut it off to get fuel, started it back up, and the light was back on (along with the quick stutter on-throttle). I pulled the cable again, drove fine on initial drive again, and now the light is back on today. However, so far, no stutter. Important note: I noticed a leak in the driver's side floorboard during the tsunami. It has never done this before, and I am now suspect that the windshield seal is crap (it was replaced before I bought the car). I am suspect that moisture is playing a key role in this CEL. I will have the windshield seal replaced next week. I have basically no experience with diagnosing anything on this car since this is the only issue it has given me during the 6 years of ownership. If a component actually is failing, then what would be a handful of things for me to check? I am guessing that the distributor is the first place to look. I know that there are several experienced B-series guys on here who might have an opinion for me before I break out the tools on Christmas day looking for a failure (or water). I will have a scan done before I tear into it. Thank you in advance. Quote Link to comment Share on other sites More sharing options...
Geeesammy Posted December 23, 2013 Report Share Posted December 23, 2013 Is it 1382 or 1392? My resource at work said the same thing, but said that the code essentially means "no signal" from the Cylinder Position sensor. I don't know a lot about Honda's, but I would see if you can find some info on what the resistance should be on the sensor itself, or at least how to test it. If you haven't gotten an answer by tomorrow around 11 A.M when I head into work I'll open up a Haynes manual and see if I can find any specs or info on an accurate way to test it. I'm not sure if a cylinder position sensor is Honda's crankshaft position sensor or what, but I guess it could be possible water got up into the sensor and shorted something out, as far as I can tell those engines only use a Crankshaft/Cylinder Position sensor, but I could be wrong. If it is indeed sending no signal, I'm amazed the car still runs. Quote Link to comment Share on other sites More sharing options...

It was why I was originally suspect that the moisture is causing the issue. I don't jump to conclusions with cars anymore, though. Since the car has a distributor, I am suspect that it is the pickup failing, but I just don't know these cars quite like I know 4G63s or 13Bs. The cap and rotor are brand new OEM pieces (3 months old). Quote Link to comment Share on other sites More sharing options...
Geeesammy Posted December 23, 2013 Report Share Posted December 23, 2013 If it was caused by the distributor acting up I'd think it would throw at least a misfire code. Quote Link to comment Share on other sites More sharing options...
greg1647545532 Posted December 23, 2013 Report Share Posted December 23, 2013 Pull off the distributor cap and take a look. I had the same error once and what had happened was that a screw had backed out from the distributor shaft and knocked around inside, dislodging the hunk of metal that triggers the camshaft position sensor. Amazingly, the car still ran pretty well, but the distributor was toast. Of course, that was an autozone reman and not a new OEM unit like yours, so ymmv. Also, I don't know much about EKs, but on EFs and DAs the wet passenger floor is caused by the seal around the blower motor intake drying out (water leaks in through the cowl.)

greg1647545532 Posted December 23, 2013 Report Share Posted December 23, 2013 And for what it's worth, there's a cylinder position sensor AND a camshaft position sensor, both in the distributor (one's a 1-tooth and the other's a 4-tooth, I think), and OBD-2 cars also have a crankshaft position sensor under the crank pulley. The ECU has so many ways to figure out the timing, it's ridiculous Quote Link to comment Share on other sites More sharing options...

FourString Posted December 24, 2013 Author Report Share Posted December 24, 2013 I pulled the cap today. There was some corrosion on the brand new cap that I just put on two months ago. I cleaned that off, but it didn't fix the issue. The rotor screw was still in. I'm going to have a scan done soon. Quote Link to comment Share on other sites More sharing options...
SinisterSS Posted December 26, 2013 Report Share Posted December 26, 2013 P1382: No signal in the Cylinder Position (CYP) sensor circuit. its gonna be 1 of 3 things: 1. Bad distributor housing sensor 2. Open wire in the circuit (I would back track any past repairs/upgrades) 3. ECM Quote Link to comment Share on other sites More sharing options...

I just read that replacing the distributor is the only way to fix an internal sensor as Honda apparently does not sell them separate.

SinisterSS Posted December 26, 2013 Report Share Posted December 26, 2013 I listed them from most common to least, BUT if the ECM got wet then I would start there, if not I'd lean towards a distributor, like I said double check to see if the car has had past repairs within that circuit. what we've seen/replaced often was the distributor, if you have friend with the same distributor see if they'll let you swap it out.

FourString Posted December 26, 2013 Author Report Share Posted December 26, 2013 Well, I can (cautiously) rule out #2 since I am the only person who has owned and worked on this car for the past six years. The car is nearly stock except for the suspension, and no repairs have been made to the car within the past two weeks (other than a brake line under the car). I just ordered a new distributor for it, and I will put that in this weekend. If that doesn't fix it, then I will address the ECU and wiring. I will check the ECU for water evidence before I do anything as a precaution. Thank you very much Craig, Greg, and Grant. I will report my findings this weekend after I install it.

Steve R. Posted December 27, 2013 Report Share Posted December 27, 2013 My money is on the distributor. However, if you want a little more info Clicky? Quote Link to comment Share on other sites More sharing options...
FourString Posted December 27, 2013 Author Report Share Posted December 27, 2013 Oh shit...sweet! Thanks Steve. I just printed that out. I'll definitely use that tomorrow. Quote Link to comment Share on other sites More sharing options...
