The 'oxygen sensor'may need to be replaced on '96 Sentra when the check engine light comes on. The should be replaced on the '96 Sentra every 100k miles for better fuel efficiency and to protect the converter.
To reset the check engine light first lift and prop up the hood of the 2002 Nissan Sentra. Then proceed to remove the negative battery cable for five seconds.
A check engine light could mean many things on a 1988 Nissan Sentra. The light could mean anything to a fuel cap not being tight enough to bad spark plugs.
It might be the catalytic converters. My 2002 had the check engine light on and it was a bad cat.
change the oil filter
You don't. Electronic feed pump. If steering gets bad, go to dealer and have pump checked.
Check with a Nissan dealer.
Check the brake switch under your pedal (which needs to be pushed when the brake pedal is depressed). This is what the problem was on my friends Sentra. As long as you have checked the lights and fuses, this should do it.
Hopefully if you are thinking of adding transmission fluid that means that you checked it..If so you are in luck, you put the trans fluid in the same place you checked it. However you have to get a transmission fluid funnel, also you need to ensure that you check it correctly. If you read the dipstick then it should have directions on how to check it. It should be checked in "park" with the engine running.
The computer has detected a problem with the emissions system. Have it repaired before it becomes serious.
Check the vacuum hose that feeds into the cruise module in the engine.
Make sure you have the ignition supply for the injectors. Check the starter signal input to the engine computer.
