Default same problem

same problem here. I found that too. theres a voluntary recall on these sensors for almost all the 00-03 models. anyways, i got the first sensor changed today $117 Canadian dollars this crap co
st me: CAMSHAFT POSITION SENSOR - BANK 1 23731-65906.

AND the first problem of the car stalling along the highway or almost anytime it pleased, is gone, for now.

but now everytime im starting the car, im having the same issue as you. its called a "hard to start warm" incident by the nissan ntb04-063. i guess i have to replace the other sensor too because they've stated: "for a hard to warm incident, replace both sensors, even if you have no codes or MIL light on". HURRRAY. another $105 for another sensor.

where can i get this sensor cheaper in canada, anyone know? Part #
23731-Al616.

Service Bulletin NTB04-063

Nissan has a bulletin out for a hard hot starting problem on the 3.5L V6 in the early 2004 Maxima and Quest, and 2003-’04 Altima models. The symptom it describes is an engine that starts OK cold, but is hard to start after it has been driven. The check engine light may or may not be on, and DTC codes P0340 (CMP sensor bank 1) and/or P0345 (CMP sensor bank 2) may be present. See Figure 5. In any event, Nissan says the fix is to replace one or both camshaft position sensors. The part number of the rear bank (bank 1) CMP sensor is 23731-65906, and the front bank (bank 2) CMP sensor is 23731-Al616. The CMP sensors are the same type as the CKP sensor, and also cost about $70 each.
