Asked by Jul 14, 2013 at 12:07 PM about the 2008 Nissan Sentra

Question type: Maintenance & Repair

On my way to the Hoover Dam, after a 2 hours of driving the servive engine light came on and the speedometer bottoms out with the RPMs going to 5 and 6000.  I let it set for 30 minutes, and started it back up with no problems til I get to the Dam nd then it acted up again.  I let it sit a while touring the Dam for a couple hours and when I start back home it does fine for 4 or 5 hours before doing it again.  What could this be?

I suspect a bad ground...clean the other side of the 1/0 cable that comes from the negative terminal....goes to the fender/frame...coarse wirebrush this connection, the place where it attaches and the lug itself...this high amperage connection "welds" itself with each use and is shared by the onboard computer and ignition system~ thermal expansion and contraction have played hell with this critical ground connection causing a "brown power" failure...pulling a battery cable waiting for 15 seconds and back again should clear the CEL~

the throttle position sensor can go kafluey after X-hours of use_____ gps=1&id=52211034499

Copy that. I checked the ground on the negative cable attached to the fender well, and it appear ok with no corrosion. However, how do I check the throttle sensor? Will this make the car feel as if the transmission may be slipping? Also, all fluids were checked and ok. Thanks
