Hello and thank you for using JustAnswer.com
Do you have a Service Engine Soon light on when the car is running?
no no lights go on
car just won't start up right away, have to try at least twice
Do you find any acceleration issues when driving?
my mechanic doesn't have sohisticated equipment suggested I take car to Nissan
How many miles are on the car?
Do you find that it's hard to start when it's warmed up, but starts fine cool?
or is it hard to start all the time?
I spoke to a Nissan dealer service dept the man said it might be the cam sensor
Give me a min
How handy are you?
why what do you need me to do, I'm a woman
I would like to unplug the cam sensor and see if you have any oil in the sensor. I can give you a image of it's location if you think you can do this. It's right up top.
not comfortable doing that
Well then that will need to be checked by someone. Cam sensors are very common as well as Crank sensors.
The way I have seen them fail is this
ok I can have the mechanic do it, can't take chance of doing something wrong
sometimes car starts right up other times it takes at least 2 tries
Oil seeps through the sensor and drowns the electrical connector. If you unplug the cam sensor and find any oil in the sensor, then the sensor should be replaced
If the sensor is being replaced, I would replace them both. Cam and Crank sensor. They are both the same part and when one fails, normally the other follows
is it an expensive job?
Na, the parts are about 40 bucks each, and to replace both sensors normally takes about a hour
So maybe 180 bucks, if the sensors are the problem
does a mechanic have to do that or could a layman do it
what could it be if not those sensors?
The Cam sensor a Layman can do, the crank sensor is a bit tricky, so I would have a mechanice replace that one.
If it's not the sensors, it could be a Mass Air flow sensor that is falling out of range, or the throttle chamber may need to have a idle relearn performed
thank you Jay I will take car back to my mechaic and have him do that. I wonder if there has been any recalls on this
You can call your local Nissan dealer and give them your vin number and have them check for recalls for you. I don't think the cam and crank sensor recall applied for your year Altima, but you can always inquire and make sure your car is up to date any way.
I will thanks
