P0345 Nissan Code - Camshaft Position Sensor Circuit Bank 2

I changed both CPS on my 2003nissan altima. I had both P0340 and P0345 codes. But now the car refuse to start even when it is cold. Any idea?

Usually the engine starts even with one bad sensor. You should start by inspecting the sensor connector (very common to have problems with the connector) if the connectors are OK, you may have to replace the Crankshaft Position Sensor as well.

I hope someone can help. I got this code. It will start but churns for a bit beforehand. I understand that there are like 3 different Cam Pos Sensors. I need Sensor A. Which one is that one?

What model and year is your Nissan? some models have 1 some have 4.

Thanks for the reply - it is a 2003 Nissan Murano.

For your 2003 Murano, there are 2 Camshaft Position Sensors and one Crankshaft Position Sensor. Most shops recommend replacing all sensor at the same time, but you don't have to.

Hi im replace my camshaft bank 2 but the light still on

What model and year is your Nissan?

04 nissan murano

Did you used a new factory sensor? usually the replacing the sensor fixes the problem. It's possible that the sensor you got is damage or the sensor was not properly installed.

Is this the same makeup as the 2007 murano? My code is p0345

Yes, is the same.

Hi guys. You probably know but just remind you very important fact. I get the same code and was ready exchange all 3 sensors which isn't really cheap. But then I discussed my problem with my friend and couple Sam Adams.......and wow! He recommended me first try to change the battery because this kind of sensor is very sensitive and need good battery condition. So I tried charge my battery (btw no signs of poor condition at all) over night, added portable charger and start the engine. Check engine light OFF, no more P0345 displayed! new battery and problem solved! GL and enjoy your Nissans ;)

Thank you for the information!!

I have an 2002 infinite g20 and it keep dying on me while I drive. I replace my O2 sensors new oils pan one camshaft sensor but my car won't read no codes

Unfortunately there are many things that could cause that problem. You could start checking the fuel pressure.

My problem started with my 2005 pathfinder got overheated and the car shutdown itself. I fix the waterpump lines and in the dash the engine light was on i didnt had a scanner in that time soo we went to a technician, he said it was a Camsensor the one who is closer to the passager side he change it ok. The car was working fine then it got overheated again and shut down again by itself in lest than a week. I put my scanner on the car and it gives me this code P0345 Camsensor A circuit malfuction bank 2 and I dont know where to start the coolant evaporated but we fill it again there is no leaks and the camsensor was new it cost i dont know what to do now. My hipotesis is that the overheated damage the camsensor I dont know. I will continue doing tests to find out.

My 02 maxima had the po345 i replaced both sensors but now Car dont start..before replacing the sensors car started good..so i remove the new sensors and back on the old sensors ans car doesnt start..help plz

Hi my nissan quest 2004 in giving me the code p0345 and c1130 already change the 3 camshaft sensor, gas pump, throttle, pedal sensor and now it wont go hired than 2000 rpm please help

After you replaced the sensors, did that clear the codes? how long it takes for the codes to comeback?

Hi, my 05 maxima had the code 0345, I replaced the sensor, then I got 0340, changed another sensor, then got 0335 so changed the 3rd sensor (crank), now again got the code 0345, the problem has always been there despite changing the sensors, car starts and drives perfect for about half hour then starts giving issue like cutting off, hard start, no power, gear slip etc. Any possible solution? Why the code is jumping from one to other?

How long it takes for the code to comeback? have you use OEM factory sensors? Other than the sensors I have not seen any other component triggering the code.

Hi, as I said after running half hour the car starts giving trouble, eml also comes on after a while. Sensors were bought from auto zone came with warranty. Thanks

It's very odd, I have worked for Nissan for over 20 years, and I have never seen any other thing triggering the Camshaft Position Sensors codes. My only recommendation is to either double check the sensors connectors or replace the sensors. The VQ engine had many problems with the sensors, but changing the sensors fixed the problem.

Ok, can you tell that on this v6 the front sensor is bank 2 (code p0345) or 1 (p0340)? I am now doubtful that the mechanic did a serious mistake by mixing the sensors by confusing the banks because I cannot see any other thing wrong with the car unless the new sensors are low quality ones.

The side in front of the radiator is Bank 2.

Mechanic did the mistake, it was 0345 and he replaced the bank 1 he said that's bank 2. The diagrams in the links is confusing for me. Anyway I got it. Thanks for your help sir

It is confusing, but I'm glad you fixed the problem. Thank you for letting us know.

Hello,
I have a 06 Xterra with 155k miles on it and yesterday I had a full engine stall while driving. The brake, VDC off, slip and service engine soon lights all came on. I lost power steering and brakes but was luckily able to coast of to the side and use my e-brake to come to a full stop. I shut the car off and waited a couple of minutes to restart the car. When I went to start the car it struggled a little bit but finally turned over. The VDC off, slip and service lights all stayed on. Once I got home I cut the car off waited about 5 minutes and tried to start the car again; I did this twice and both times the car struggled to turnover. I had to hunt down my OBD reader which took about 45minutes and I pulled the p0345 code to find out that its the CPS bank 2. Fast-forwarding a couple of hours, I went to go start the car and had no issues at all. VDC off and Slip lights were now no longer lit. I pulled the sensor today expecting it to be a nasty mess but it wasn't. I went ahead and ordered a new one but I was hoping to hear other peoples thoughts on why the sensor looking so clean and new. I don't believe it's an OEM product and I have not looked up what brand it is. I know that some of the different brands of sensors tend to "go bad" faster than others. Any and all thoughts or suggestions are welcomed.

Sounds like a typical Camshaft Position Sensor failure. The sensors are usually clean, unless stuff is coming apart inside the engine or you don't change the engine oil regularly. You should also consider replacing the Bank 1 sensor as well.

Thanks for the reply. I had planned on knocking out bank 1 as well. I seem to remember a mechanic buddy of mine tell me that if one of them goes it makes sense to replace both at the same time. Bank 2's will be here tomorrow and the other one will be here Saturday or Monday.

I call BS. Disconnecting the battery will clear the code(s), issue will return. The sensors are supplied with a 5 vdc reference volt just for the purpose of being able to operate without voltage fluctuations affecting perform. If the battery voltage was low enough(under 5 vdc) to cause this code, your engine couldn't crank over. If it was an issue with the 5 vdc supply or ground circuit problem issue would affect ALL engine sensors as they share both supply and grounds for circuit. Install the sensors and be done with it.

So I am wondering if the alternator can cause this problem? the alternator is the control voltage for the cars electrical sys after the startup. I am having this problem on a 2006 350Z. The alternator gage shows 14+ volts and that is a little above normal.
