Method, control device and apparatus for analyzing a gas

The invention relates to a method (200) for analyzing a gas (108) to a heatable element (106) for a lambda probe (102), said method (200) includes a step (202) of reading and a step (204) of determining having. In step (202) of reading a value of a to the heatable member (106) is read in heating power provided for maintaining a predetermined temperature of the heating element (106). In step (204) of determining a determined gas composition of the gas (108) to the heatable member (106) by using the value of the heating power.
