2001 Nissan Sentra: die..the car radio turns off or it loses the sound

Resolved Question:

I own a 2001 Nissan Sentra. For the past 2 days the o/d light has been flashing and when it does it feels like the car is going to die on me. And just before it stops flashing the car radio turns off or it loses the sound and then turns back on again at which point the o/d is no longer flashing.

The o/d light flashes when there is a transmission problem and code stored in the transmission control unit. A sensor such as the throttle position sensor is heavily integrated in both engine and transmission systems and can cause problems in both. The radio sound turning off while this is happening is a mystery. Start by checking the battery connections for being tight and clean, and making sure the trans fluid is full, red in color, and does not smell burnt. Then have the engine and transmission control units scanned for codes. There are some recalls that can cause poor running and transmission problems. One is for engine control module foam causing failures, and the other is for engine cam/crank position sensors. Make sure both of those have been done by calling a dealer and giving them your vin#.
