Could be cam sensor or timing belt/chain is out of tolerance.
the ecm checks the cam and crank sensor to make sure they are working in unison. when the belt/chain stretches the sensors will pick it up.

this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.

If you have bearing problems MAP sensor codes are the least of your worries. Check on the cost of getting a new engine. I hope this is not the problem. Good luck Moe
SOURCE: where crank shaft and camshaft?
Hi I have a 2002 altima and I just fixed all that stuff. The crankshaft sensor is a different sensor and located in a different place. The crankshaft pos. sensor is located in back of the motor next to the firewall maybe half way down toward the driver side. there was a few tricks to getting to it and replacing it that no one mentioned it but I got it down. I replaced it 3 or for times till I got the right one so I was able to do the whole thing in about 15 min at the end. if you still need help email me, its kinda easy once you know what youre looking for!

the computer may need to be reflashed. if it is running then it is not a bad sensor. either of those being bad would cause it not to run.

P1151 means a lean bank 2 O2 sensor
P1152 Means a rich bank 2 O2 sensor
P1309 Means miss fire detected
I would check your fuel injector for fouling
When they foul the will develop a drip
Causing a fuel fluctuation that will have O2 sensors reporting rich and lean voltage changes
This causes the pcm to adjust injector pulses making them shorter and longer.
causing more fuel or less fuel.
From this condition you may see plug fouling.
Also check for leaking or faulty fuel pressure regulator or restricted return line.
Most of the time it wont be a bad O2 sensor the O2 sensor is just doing its job.
You also have already changed the plugs and Map so there already out of the way.
If this helps please give me some feed back
Hope this works for you FixYa
A camshaft position sensor,or cylinder identification sensor is used to determin the engine cycle position the information is used to provide individual cylinder ignition and injection cotrol.Many engine mangement systems use an inductive type of sensor that is located near the camshaft;when the camshaft rotates a single signal is passed to the ECU to indicate a reference point in the engine cycle
