Crankshaft and camshaft position sensors can leak oil into the connector causing Check Engine Light illumination. The engine may also stall as a result. Leaking sensors should be replaced. Certain 2002 models were recalled for a separate camshaft and crankshaft sensor issue. For more information on the recall please click here»Google+

The car would stall or not start. It was bad cam and crankshaft sensors. I replaced the sensors. Upon researching it, it seemed like this was a widespread problem that probably should have been covered with a recall.

I had the same problem everyone else is having the cam and crankshaft sensor with my check engine light on except my car has now stalled twice on me. I called nissans consumer affairs....got the same story as everyone else...some how my 2003 nissan altima vin # is not included.....but they will forward it up to the regional office of consumer affairs and have them look into replacing the parts except first I have a diagnostic report ran on my car...which is $259 and they will not wave the fee. but i MIGHT be able to get reimbursed for it...then get transferred to some nissan dealership in albany and a guy named ED saying they cant get to it until thursday or friday and he needs it for 24-48 hours but refuses to give me a rental, So i hung up on him and called Gerry the supervisor at nissan consumer affairs back.....just to be disconnected while on hold waiting for them to look into the case...nissan is just giving people the run around and this a serious problem!!!!! whats going to happen.....someone get in an accident and kill somebody before something about this changes?

I have replaced the crankshaft sensor twice in 2 days. The check engine light just wont stay cleared. I am going to be replacing the connector since I feel it is broken. Hopefully it is the problem.

Camshaft sensor went bad. Car was cutting off while driving. I was told repair shop this is a very common problem with Nissan Altima's. Cost of repair(labor and part) was $165

service engine soon light on...diagnosis: cam and crank position sensors
Check light came on, car will not start up, computer readings position off. No diagnosis yet and no fix yet. Working on passenger air bag light flashing with or without passenger and failed external seal on engine oil cooler.

Service Engine Soon showed up. Camshaft sensor flooded with oil. Warm start needs extra a few seconds of cranking; cold start normal. Replaced with a NAPA sensor, symptom disappears, but warning light still on. Only has 2 trips, will see if more trips can turn the warning light off.
