Check the fuse box. Battery voltage comes from 15 amp fuse #8 in the under-dash fuse box. That should cure your problem.

Note - not a solution..just adding my woes!
I drive a 2003 Nissan Sentra SE-R Spec V.
My car suddenly stalled 1 day and the engine wouldn\'t turn over. Brought it to my mechanic and had the Camshaft position sensor replaced by my mechanic. The car ran fine for about 2 weeks and then the light was back on with the initial symptoms.

Took the car into the dealership and they diagnosed it again as P0335. Said that the mechanic hadn\'t installed the sensor correctly. Charged me a bunch of money to replace the thing and not too long ago the check engine light is on. The Revs bounce around everywhere. Checked the code again and it\'s P0335 yet again! Am in talks with the dealership to get to the bottom of this...

I have a 2004 NISSAN SENTRA SE R SPEC V (Nismo), my car sputters


You have 2 Problems, First problem batteries dying you have to make sure connections secure and alternator is charging your batteries (go to an Autozone or Discount advanced they will tell you). The Sputtering is either a bad SPARK PLUG or a damaged Cable going to the spark plug..Change them every 2 years.

Hey


Most times when you have a cut in power when the RPM's are high that's most likely a "SPARK" problem. However it can also be a "GAS " problem. Does check engine light come ON if it is or even if it NOT ON there can still be a Code stores in your computer. My first thing would be a BAD CRANK sensor/CAM sensor. This is my recommendations you should have this vehicle place on a code scanner/computer AUTO-ZONE does this check for free then get the codes if any is present and get back to me asap. I strongly thing it would be a crank sensor but if not there is a 20% chance its a FUEL PUMP can meet the demand when you hit the gas therefore then engine starves and dies. LEt me know how you made out. Good Luck and Thanks for using FIX YA
