Question about Nissan Sentra
If the O/D light was on, then a transmission problem has occurred.
Theproblem may had been occasional. There are many different conditionsthan a simple contact that can cause this (from a slipping transmissionto a bad ground). The O/D module light flashes when an automatic transmission fault has been detected by the ECU.If the problem happens again there may be codes stored in the ECU andprobably in TCM even if check engine light does not come on.
Youcan first try disconnecting battery ground cable for five minutes. Thiswill reset the ECU. If possible do a code scanning before doing thisoperation. Disconnecting the battery you will also reset the errorcodes stored in the car module. Ensure that you have c anti theft code if needed.
The first step in troubleshooting is reading fault codes.
Ifthe problem is an auto transmission not shifting correctly, then commonfaults are TPS sensor, TCM (transmission control module), Transmissionshif solenoid and more.
If the car is drivable, then a code scanning can be performed for free at the nearest Autozone.
Whenproblem is transmission you often get a P0700 error, that would meanthat more codes are stored in a different module (TCM). The TCM can bescanned at the dealer or at an autorized garage.
Other codes (like P0500, vehicle speed sensor), will point directly at the faulty part that is causing trnsmission malfunction.
As mentioned, the TCM is the computer modulecontrolling the transaxle, see: I get code p0700 after an OBDII scan.
Thereare many possible reasons for automatic transmissionmalfunctions. Mostcommon transmission malfunctions are discussed here:My car does not shift..
If you want to do the code scanning by yourself, you will need to use an OBDII tool like this one:Autel MaxiScan MS409 OBD-II/EOBD Scanner
If there are no OBDII codes, then the O/D codes can be scanned with a Com tool available at certified garage.
Note: The 16 times flashing it is not a code. The codes are short and long.

Engine stall or RPM fluctuates
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
