Hi, Jagpro told me that my new coolant level sensor gotta to be reset becuase the "low coolant " warning is still on now ?

Any one knows how? I still can't understand the paper clip trick

 

The reset is to have a fully functional sensor. The dash alarm will then go off.

The sensor is a normally open connection. When installed in the reservoir and affected by the coolant floating the 'donut' magnet it closes a contact in a tiny glass capsule. That means that the ECM is expecting to see a 'short', or closed contact, from the sensor when the coolant level is within the 'correct' sensor range. The magnet donut, after floating around in old coolant crud, sticks to the tube that isolates the reservoir from the rest of the world.

The 'low coolant' bypass is to remove the connector, the one with the wires going to the ECM and 'jump' the two connections with a small piece of wire and then tape in in place. You can no longer plug it into the sensor connector and it will have to just dangle there.

Nothing more I can do to explain that.

Of course, you could have a broken circuit between the connector and the ECM in which case the above bypass would not resolve the problem.
