Just from recent experience, I have noticed when my check engine light has come on and I want it to go away, I cycle the key to the position right before actually starting the car up three times. The real way to erase it is by using the diagnostic tool at your local autoparts store, plus its free!! An "Advance Auto Parts" or "AutoZone" or any other typical auto parts store will be able to hook up their OBD II device to your ODB II port typically under the dash, around/near the steering wheel. They can tell you what is giving the code, and also clear/reset the code. Now, if the light turns on again? Take it back there, have them give you the code again (if it's a new/different code) - have them reset it, then go have the problem fixed. I've also heard you can reset it by removing the negative terminal from the battery....but I'm not really a mechanic type....so not too sure.
If the check engine light stays on for the Nissan Pulsar n16, you would need to check the engine in order to clear codes. You can take the car for service and the problem will be diagnosed and restored to normalcy.
Auto Zone will check your engine codes and if you ask they will clear your codes for FREE.
pretty much instantly. As soon as the codes are cleared the check engine light goes off and vice versa, unless there still is trouble. In this case the codes won't clear until the trouble is repaired.
Fix the cause of the codes, and clear the codes with a scanner or by unhooking the battery.
You can disconnect the battery for about 5 minutes and this will clear the check engine codes stored in the computer. If the problem that caused the code has not been repaired the check engine code will just happen again. The only way to get the check engine light to not be on is to repair the problem then clear the codes.
Many cars will keep a history of any codes that have been tripped since the last time the codes were cleared. Once codes are cleared by a scanner they are erased permenantly.
After reading the codes, and repairing them, you clear the codes with a scan tool.
A person can reset the check engine light by using an OBD scanner to clear the codes. This is after the problem is fixed.
check obd2 with scanner for trouble codes find problem, fix or replace sensor or part, clear codes with scan tool
Disconnect the Battery. Negative prefered. Wait a couple minutes and reconnect. This will clear codes on 1994 and older. If the light comes back on, check the trouble codes and a repair may be needed.
you can either purchase a computer programmer ($200-$350+) that will allow you to check and clear codes as well as adjust computer settings for maximum performance or take the vehicle to most auto parts stores that can check the codes for free.
Either try disconnecting the battery for about 10 minutes or have vehicle scanned to determine problem and clear codes
