My Check Engine light came on last week. I followed the instructions to obtain the code which is 03 13. That code is not listed. I checked three times and this is the correct code. Can anyone help?

 

you got 3 short and 13 long? I can't find that anywhere.

 

I received 3 long and 13 short. Checked it three times and this is what I got. I can't find that code anywhere either. What happens if I reset the ECU? Will the problem code appear again?

 

It might, I think people have posted about bizarre ECU codes when there is a loose connection in the harness. I would suggest feeling back behind the ECU and push the harness connections in check the MAF and other connections under the hood. After all of that I would then reset the ECU and hope that it doesn't come back.

 

Sorry dude.. I cant find that code... 03-01 is an ECU calculation Function is malfunctioning. 03-13 is not in the books... I agree with SLC I30t check your connection and try again .. hopefully thats all it is and everything will work out. If you need any other codes drop me a line...

 

Thanks for checking for me. I will check the connections this weekend, reset and see what happens. Please excuse my ignorance but what is the MAP? I came across this site last week looking for information on the check engine light self diagnosis. I thought maybe one of the O2 sensors went. I like to maintain my vehicles myself and hate to pay big money for something I can do myself. I'm by no means a "mechanic" but boy is there a huge amount of valuable information in here. I have a 99 SE with just under 40K. I had a 90 SE before this one and never had to do anything other than rountine maintenance before (other than a bad fuel injector which was covered under warranty). I sold it to buy this one. I've already told my other friends with Maxima's about this site. I never thought about mods before but now have the bug. Hopefully there is no problem. Thanks again.

 

Scan Tool Trouble Code = 0158

Description: Downstream oxygen sensor maximum voltage monitor fault


This is similar to DTC 0510, which is described as follows:

Diagnostic Trouble Code 0510 points to a problem with the Rear Heated Oxygen Sensor. This sensor is mounted in the exhaust stream, just downstream of the Catalytic Converter. When the two Front Heated Oxygen Sensorsare operating properly the Rear Heated Oxygen Sensor is not used for engine control operation. It is used to monitor the condition of the Catalytic Converter. If either (or both) Front Sensors fail, the Engine Control Module uses the signal from the Rear Sensor to maintain a correct fuel/air mixture.

DTC 0510 is detected when the signal from the Rear Heated Oxygen Sensor does not reach the expected maximum voltage threshold value.

The possible causes include ...

- Harness or connectors (the sensor circuit is open or shorted.)
- Rear Heated Oxygen Sensor
- Fuel pressure
- Fuel injectors
- Intake air leaks

These search results should help as well:

It's odd that you got the 0313 code, but perhaps it is because this applies to 99 models, which do have a farily different ECU than other years (98 and prior). Both the DTC 0313 and DTC 0510 codes point to DOWNSTREAM oxygen sensor maximum voltage issues, and since the Maxima only has one "rear" oxygen sensor, that has to be it.

I would say your rear oxygen sensor is toast. And I would bet you are just out of warranty as well.

My Haynes manual, which provided this information, has a set of codes for the "left bank" and "right bank" (also referred to as UPSTREAM) and than 2 sets of DTC codes for the DOWNSTREAM oxygen sensor. Odd indeed.

Hopefully it's just a 99 model year difference.


Good luck.

 

I also have this code, and the fact that I couldn't find 0313 anywhere stumped me too.

Iif it's good info for anyone, I got the 0313, and checked the code with my friend's garage's scanner, and got the same info as the haynes manual states, P0158. I know the haynes is pretty reliable as far as info is concerned, but a corroboration won't hurt.

Anyway, that's enough info for me to purchase a rear o2 sensor and install it. btw, with an older car I've had o2 sensor trouble with, removing the sensor revealed lots of carbon-type crap on it, cleaning it didn't help there either, but I just thought I'd mention that I took a look at this one on the max after getting the P0158 code, and it was as clean as a whistle.

I'll replace it and see if the code comes back. Currently it's appearing about once every tank of gas, and it shows up alone, no other codes along with it.

WhoWhat?,

Just got off the phone with the dealer, that's a dealer-only part (surprise surprise) and goes for $80. Be prepared to give the parts counter your VIN as there are several available for the 99, depending on manufacter month.

It's a very easy install though, if you have or can borrow a O2 socket. Mine came out easily, the hardest part is carefully cutting the wire ties back up the front of the engine to the connector. I replaced the ties with nylon zip-ties.

The "MAP" is the map sensor. The map sensor measures air pressure as the vehical travels, as you increase your elevation, or the weater and climate changes it will adjust the air = fuel mixture. I hope this helped you out and yes it is a dealer ONLY item to my knowledge. well if you need any thing else buzz me... Jason

 

not all codes are on that website.. but chances are if you put the 4 numbers in the search function it will return an Answer by DBM, Bill or iwannabmw with the correct code

 

Yeah, I was surprised 0313 hasn't ever been mentioned.......which is why I inferred a possible link between it being a '99 ECU thing since the 02 sensors haven't had enough time to go out like they have in 95 to 97s....

 

Thanks for the info. I was reading another O2 thread and someone mentioned that 87 octane can sometimes cause an O2 error. The wifey sometimes sneaks in 87 octane . Would I be better to reset the ECU and see if the code returns than go ahead and replace? 99 SE with 39,000 miles. Any yes, of course I am just out of warranty.

 

also keep in mind the rear 02 sensor has no major functionality on your car.. it doesn't affect performance or anything.. it only monitors the catalytic convertor.. so its really no rush to replace.. resetting and seeing if it comes back is a great idea..

 

Yeah, definitely do a reset and see if the light returns. I doubt at such an early mileage, an occasional use of 87 octane would cause the O2 to go bad.


As search shows, I *think* a bad cat can (although rarely) cause this issue as well. But since it's an over voltage type of issue, I would still gamble that the O2 is bad.

Like Sprint said, the 3rd damn 02 sensor doesn't do jack.
