- Turn the ignition switch to the “On” position without starting the engine. This will activate the diagnostic mode.
- Wait for the Service Engine Soon Light to start flashing. Count the number of flashes. Each flash represents a specific trouble code.
- After counting the flashes, turn the ignition switch off and remove the jumper cable or wire from the diagnostic port.
- Wait for a few seconds, then reinsert the jumper cable or wire into the diagnostic port.
- Turn the ignition switch to the “On” position again. The Service Engine Soon Light should start flashing again.
- Count the number of flashes once more. If the light flashes the same number of times as before, it indicates that the reset was successful.
- Finally, turn the ignition switch off and remove the jumper cable or wire from the diagnostic port. The Service Engine Soon Light should now be reset.
Cleaning the MAF sensor
A dirty Mass Airflow (MAF) sensor is a common cause for the Service Engine Soon Light to illuminate. The MAF sensor measures the amount of air entering your vehicle’s engine and plays a crucial role in the fuel-to-air ratio.
To clean the MAF sensor on your Nissan and potentially resolve the issue, follow these steps:
- Locate the MAF sensor, which is usually situated between the air filter box and the engine intake manifold.
- Remove the electrical connector from the MAF sensor by carefully unplugging it.
- Using an approved MAF sensor cleaner, spray the sensor carefully and thoroughly to remove any dirt, oil, or debris.
- Allow the MAF sensor to dry completely before reconnecting the electrical connector.
- Reconnect the electrical connector to the MAF sensor.
- Start your Nissan and check if the Service Engine Soon Light has turned off.
Replacing a faulty oxygen sensor
A faulty oxygen sensor is another common culprit behind an illuminated Service Engine Soon Light. The oxygen sensor measures the oxygen levels in the exhaust gases, helping the engine control module (ECM) maintain the optimum air-to-fuel ratio.
To replace a faulty oxygen sensor, follow these steps:
- Locate the faulty oxygen sensor. Depending on your Nissan model, there may be multiple oxygen sensors located before and after the catalytic converter.
- Disconnect the electrical connector from the faulty oxygen sensor.
- Using an oxygen sensor socket or a wrench, carefully remove the old sensor from the exhaust system.
- Apply a small amount of anti-seize compound to the threads of the new oxygen sensor to prevent it from getting stuck in the exhaust system.
- Thread the new oxygen sensor into the exhaust system by hand until it is snug.
- Tighten the oxygen sensor using an oxygen sensor socket or a wrench, ensuring not to overtighten.
- Reconnect the electrical connector to the new oxygen sensor.
- Start your Nissan and monitor if the Service Engine Soon Light has turned off.
By resolving these simple issues on your own, you can effectively turn off the Service Engine Soon Light on your Nissan and save time and money in the process. Remember to always consult your vehicle’s owner’s manual for specific instructions and troubleshooting tips unique to your Nissan model.
