Did he have the same symptoms

 

Try resetting the ecu . If that dont work double check Your oil level, and make sure the sensor and connection is snug . Check Your timing.
If light comes back on pull the codes again

Next charge the battery, and have the starter checked out like someone said. If all that is ok then check for a bad ground or short
Keep us posted .gl

 

Yes we went thru the sensor dance and no luck. His car was actually not starting all the time tho. Try swapping the other cam sensor on that side with ur brother. This one is like on the exhaust cam and has a angled connector.

 

Reset the ecu multiple times to no avail. Charged the battery still nothing. Check timing how ? Light comes on and it's the same code. I'll get the starter checked out too and God the ground. Yes I will try the other sensor too but being as it pulled bank one I believe the bank 2 wouldn't trip it but I'll try it.

 

Same back just on the other cam.

 

I bought sensor 23731 6J90B and had this problem less than a day. Do u still have the pack from nissan?
