How do I reset check engine soon light 3.5 altima 2002?


The best way is to use an OBD II scan tool. If whatever has caused the light to come on is fixed, after 3 consecutive key on cycles of where no problems are found and the diagostic monitor is run, the light will go out. You can disconnect the B+ power supply for the computer, or disconnect the battery, but this is not recommended.

1996 nissan altima engine stalls when going uphill


If you recently replaced the battery, you may need to reset the idle air control valve setting. This is done by removing the NEGATIVE battery wire from the battery while the vehicle is HOT. Then you must wait several hours for the vehicle engine to become cold. Next, once could, reconnect the negative cable. Start the vehicle, place your foot on the brake and imediately put the vehicle in drive. Stay in that situation until the vehicle engine bcomes hot to normal temperature range. This will be known by hearing the radiator cooling fan turning on. You must NOT use the airconditioner during this cause it will be on during the event. Once accomlplished place in park and allow the engine to cool, engine off. This resets the engine computer to tell the idle/load speed control valve to add air and resuling in additional fuel to the engine under various torque loads.

Check engine light is on 2002 taurus SEL DOHC


it could have been running bad with the bad plugs. reset the computer and see if the light comes back on. you may have already fixed it. to reset the computer take the positive cable from the car off the battery and give it 3-5min to discharge then touch the positive cable from the car to the negative cable (still attached to the battery) for about 5 seconds and then hook back up the positive post and that will reset the computer.

Does the vehicle shift funny? The code means engine speed signal which is probably the vehicle speed sensor is defective. It is located on the transmission where the speedometer cable used to go. Is located under the hood by the firewall.
