New CEL

[ajflan]

Well, its not really that new, but I just got it read while I was getting my oil changed. They said it was a P1600 or something. They also referred to it as "auxiliary error" or something. Then they said that they have no idea what it is or what is causing it. Now, I assume that it has something to do with my unichip, but I don't have a clue what it is. I had my ecu reset, but that made no difference. Does anybody know what would be causing this? Thanks.

Best i found for ya mans it this...P0160 Generic O2 Circuit No Activity Detected (Bank 2, Sensor 2) Which i found here... http://www.iequus.com/index.phpGood luck...!!

It sounds like the header is your problem.You have to get the new MAP uploaded.

There is no such code as P1600. You'll need to get it read and remember the code in order to diagnose the problem. If it is P160, it's the second o2 sensor, not the one on the header(exhaust manifold).

see if this helpsalso check the EFI fuse

From the PDF file from joatmon, it would seem to point to the Unichip as the culprit. P1600 must be a rare and unusual code as it is not included in my code book.

[kevera]

It's the map that's loaded in the unichip.It can't compensate for the extra flow from the header.He needs a new map loaded.

[kevera]

You know what.I wish you would have emailed me before you installed the uni-chip.Anyways,there is a switch for boosted on the harness,maybe you have it selected to boosted when it should be off.

I posted this about a week or so ago http://forums.genvibe.com/zerothread?id=29229 with absolutely no responses yet you post and you get 7 or 8 in one day . I guess I'm just not in the right cliques on here.Anywho, I disconnected my Unichip and connected everything without it. No CEL. I then figured it was the switch. Since I had the same CEL without a Header replacement, its not that.It's more than likely the Power Cut switch on the Unichip. I'm assuming the CEL is caused by the computer not being able to retain memory. Check my link above, I listed everything the P1600 could be. I tinkered with the switch a bit and now I've been without the CEL for about a week or so. If it comes back, I'm changing the switch. Check the Power Cut switch.Sincerely and humbly,Dave

[ajflan]

Sorry that your post was not replied to, I am sure it was unintentional. What did you do with the power cut cord to get rid of the cel?

[DavidPIL]

ajflan,Not much really, I just disconnected the whole thing then reconnected it then made sure the wires were secure in the end of the switch. I'm honestly just assuming that was the issue since I had started the car after reconnecting everything and still had the CEL. Only after pushing the wires into the backside of the switch did it start up w/o the CEL. Again, I'm assuming the switch is bad, whether it's the connection of the wires or the switch itself. My fix is more than likely a temporary one. if/when it resurfaces, a new switch will be my first purchase.As for your CEL coming on coincidentally with the oil change, mine came on when I cleaned my MAF and removed an "added" ground wire. I thought that might have been the problem but since it went away while doing the switch thing, I don't think it was.I just set my switches up in the glove box. I have small tools and a handfull of papers and booklets in there. It's very likely that while putting something in or taking something out of the glove box, I could have tugged a wire or bumped the switch somehow to cause it not to work.Basically, it's a simple check (the connections of the Chip, the switches and the wiring) then it's a simple fix if it's only the switch. In the least, It's a place to start.Good luck!Dave

Hey Sunny,When Auto-Zone checked mine, first off, they couldn't get their reader to work. a few days later I went to another A-Z and they came up with an OEM (Or was it a proprietary code? - I don't remember) code then had to check it inside. Gave me a rather long list of things it could be, which I listed in the thread http://forums.genvibe.com/zerothread?id=29229. FOr me, it was definitely the issue with the ECU's long term memory, which wasn't being allowed by the issue with the Power Cut switch. ANy other combination of the others listed could have been an additional cause as well.Dave

[ajflan]

My cel went away for a few minutes last night. I got all exited but then it came back. I was installing the switches in a new location, and I found out that when I pulled the power switch off and put it back on, the car would start 2-3 times with no cel. But then, of course, it came back with a vengance. Oh well.

Have you tried resetting the ECU???

[ajflan]

Yeah I tried resetting the ecu. Nothing works, it's always there.

[kevera]

Did you check all the connections.Maybe make sure none of the wires on any of the connectors are loose.And did you make sure you hooked it up properly.

[ajflan]

I'm pretty sure everything is hooked up properly. I have nothing to do right now, so I think I will re-install everything. It can't hurt. I'll also take a couple of pics of the way I mounted the switches.

[kevera]

Just make sure you disconnect the battery first.And check that little switch that says boosted,make sure it's off.

[ajflan]

I will let you know how it goes. Stay tuned...

[ajflan]

No change at all. I'll just have to live with it. No biggie.
