Question about 2006 Nissan Altima

1 Answer

Nissan altima starting problem


I have a 2005 Altima 2.5S.(42k miles) I've had the car for 2 years and not had any problems. However for the last 2 days, its not starting properly on the first try. In some cases I have to let the car sit for 40 minutes before getting it to start up. The battery is brand new. The engine cranks over without any hesitation.

I've tried starting holding the peddle down 2/3 down (as suggested on some forums) - no luck
I've removed the battery terminal (in hopes it resets something) - no luck.

I connected an ODB II scanner and I get "Camshaft Sensor - Malfunction on Circuit 1" (Cen-Tech error code P0340)

I see there is a recall to reprogram the ECM - would this fix the problem. Or should I change the sensor?

I have a 2006 Nissan Altima and it does not start properly either. I have taken it to the dealer 3 times about this and they can not get it to "duplicate" they say. I need to know what the cause of this problem is? Can someone please help!!!

This is definitely a camshaft sensor malfunction, you can get away with not replacing it for awhile but eventually when it goes the car will stop starting, the sensor will need to be replaced hence why your car isn't starting but intermittently. Its easy to do and will take about 30 minutes to do, its just a pain to get to.

i think replacing the sensor is in order. i know all car makes have "recalibration updates" for the ecm and should be done, but have rarely fixed vehicles on just that alone. and your symptoms suggest the sensor could be intermittently bad

I have a 2003 Nissan Altima. Do I have a timing Chain or Belt. How long does the timing chain last? I have 195,000 miles on my car.

Timing chain. Normally they will last for at least 150,000 miles or longer. If it becomes noisy or car is hard to start, backfires, or performance is sub-par have it checked.

2003 altima cruise control button broke off.

I've had the same problem on a 2004. The SET button has popped off for the second time now. Last time I bought the cluster and repaired myself. Hey, plastic parts break but my complaint is that Nissan should supply a $5 plastic button that would just pop in the spot where the old button was. As is you must buy the whole control cluster. That's just wrong!

Poor fuel mileage with my 02 nissan altima

yes it very possible because the catalytic converter is part of the emissions and you need to ask yourself when was the last time you had a good tuneup drive belt,sparks and wires if needed and a fuel filter and a pvc valve.
