Your Nissan Sentra SE service engine soon light comes on is it serious your milage is 50K miles how can you reset the light off?

Answer 1

CHECK ENGINE LIGHT RESET/DIAGNOSTIC PROCEDURE

In car ECM Diagnostics/ECM Reset procedure:

1) Sit in the driver's seat.

2) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)

3) Fully depress and release the accelerator pedal five times in less than five seconds.

4) Wait exactly seven seconds. Fully depress the accelerator pedal for ten seconds until the MIL light flashes.

5) Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.

Long flashes (0.6 seconds) indicate the first digit of the code; count the blinks one through nine and write down the first digit. (Ten blinks indicates a zero.)

The next three digits follow in turn in the same fashion except with faster blinks (0.3 second) and a 1.0-second pause between digits.

The ECM code repeats itself until you turn the ignition key to the OFF position, at which point the ECM resets itself to standard get-in-and-drive-the-car mode.

You can look up the trouble codes in the ESM/FSM; there's a bunch of them. In the ESM, refer to page EC-639.

Additionally, if you get four blinks of ten (0000), the ECM is indicating no malfunction.

Clearing

You can clear the code (and the annoying MIL) by holding down the accelerator pedal for more than 10 seconds while in Diagnostic Test Mode II. When you release the pedal, the ECM erases the trouble code(s).
