travel computer

how can I reset the travel computer? because display "coolant sensor bad" I all ready change it,but the display still with the same message.
Please help me!!!

well it should reset itself when the Sensor got replaced. check all the wires goign from the Sensor, make sure it is plugged in and that none of the wires are bare.

Step until you see "coolant sensor bad" then press the reset button on the overhead console.
