A method of controlling water injection in an internal combustion engine for a motor vehicle in case of freezing cold weather. The method includes: controlling the quality of the water, having a first sub-step of disapproving the quality of the water if the electrical conductivity σ of the water is not zero nor close to zero when the temperature T of the water is 0° C. or less and a second sub-step of approving the quality of the water if the electrical conductivity σ of the water is zero or close to zero when the temperature T of the water is higher than −4° C., preferably higher than −2° C. The method further includes a second sub-step of preventing water injection if the quality of the water is disapproved and a third step of allowing water injection if the quality of the water is approved.
