4 trouble codes on the max

[asiancivicmaniac]

So I went to Autozone to have the problem codes read because the check engine light came on. The following returned: p1612, p1800, p1147, p0139.

According to the Autozone printout they mean the following:
p1612: Nissan Anti-theft System failure

p1800: variable induction air-intake system control solenoid valve

p1147: ho2s12 maximum voltage not met

p0139: heated oxygen sensor response time too slow (think 1147 is related)

Help?

Think my worst fear about buying a used car is slowly becoming reality. Which one of these can be left alone for a while without really bad repercussions?

As long as you don't live in a bad area where you are worried something may happen to your car and the anti theft system doesn't effect you starting or driving your car. I say that one is the one you can leave alone while fixing the others.

All these codes showing up at the same time doesn't make a whole lot of sense. I would reset the codes and the battery and drive to see if the Check Engine light comes back on. If it does then scan it again and see what comes up.

I think it might have had a low battery or something and caused it to store weird codes like a bad ground to the computer etc.

The battery was discharged from sitting on the lot for a long time. It has started up fine though since then and the electrolyte is full.

Oh, I also had a bottle of Regane in the tank. I don't think it affected anything though.

StevieC I hope you're right. Could the theft system be a blown fuse?

 

[StevieC]

I think all the codes are related to a flat battery and may have just been delayed in setting the check engine light. Flat batteries (low voltage) can cause computer circuits to do weird things.

I would have all the codes reset, and try driving it to see if the light returns.

I left my lights on in a car and it killed the battery. I boosted it and it did something similar as yours... It set all kinds of funky codes... I reset the codes and the light never came back.

Do you think the dealer cleared all the codes before they sold you that Maxima ?

I'm sure maxima.org will have the answers to all those codes.

Sign up for an account on maxima.org as mentioned above. Reset the codes and see what pops up. Some of these may be related.

It's funny that the anti-theft is saying that it's failing because the security light flashes when the key is out of the ignition. I'll go get it reset tomorrow. I'm at school and don't have any tools to disconnect the battery.

I don't know. It drove fine when we test drove it and there wasn't any noise. The light appeared after I drove the car for 300 miles. But like StevieC said, the codes occurring together is kind of odd. The o2 sensor might be right with the mileage on it but the anti-theft and the vias (which I don't have a clue what it is) seems strange.

The people didn't seem sketchy to me like the other dealerships I've went to.

I did a search for all the codes on maxima.org and there weren't any results. Could be that I'm not a member, but I'll ask there later. Now I'm going to take a nap so I can stay up all night to write about a favorite saint for my Roman Catholicism class (fun-fun-fun). I hope this thread progresses.

Properly clear the codes and see what pops up again, if anything.
Like mentioned, the 'all at once' thing is a clue.

Take it back to the dealer. I assume there is some kind of warranty. Most likely the CEL was reset before purchase.

 

[asiancivicmaniac]

No warranty

If you have a AutoZone close by, they will scan your codes for free. Give the guy who will scan the codes a couple of bucks, and he'll reset them for you. Worst comes to worst, go to WalMart, buy a OBD II reader, reset your codes and return the item back. If and when the codes come back, we'll go from there. For now, just clear all the codes.

Or just keep it, if you can spare the cash. A code reader is a nice tool to have.

 

[asiancivicmaniac]

I going to try this first

http://maxima.theowensfamily.com/ecu.asp . Looks kind of crazy. Almost like DDR with the gas pedal.

 

[asiancivicmaniac]

If I need to get a scanner, which one of these should I get?
one
two
three
four
five

I recommend this one if you want a good one:

I don't know about for Nissan, but for GM I've always heard good things about the AutoTap. It gives you a lot more information besides just the codes, and much of it can be used to diagnose annoying sensor problems. Does start at $200, though.

Now that they have CAN support, I've been thinking about picking one up. I've got what I think is a lazy o2 sensor in my Jeep, but who knows if its that or a bad TPS or something else.

You're also going to need a laptop computer to use the AutoTap, if you don't have one already.

I have a scanner form obd-2.com, you'll need a laptop. The interface is not the easiest thing to learn, but I has support for lots of different cars and the price is very fair.
