Lambda probe

Ford Focus 1.6 Gasoline of the year 2005,
I have the light of the engine on, and I get in the OBD the P0037, "control circuit of the heater of the Lambda tube heated under the under the minimum threshold. DTC present at the time of the application".
I have changed the probe but follow the breakdown.
Anyone who helps me?
thank you.

Two things if you changed the sensor you deleted the computer codes? And second the Lambda probe of 3 and 4 roads or cables are heater you will have to check that the connector cables that carry the heater current are usually the two of white and another Czech thing that is well connected the cables and are not crushed.

Hello, control the rifle since the probe resistance is fed with 12 volts greetings
