PROBLEM TO BE SOLVED: To enhance the precision of a signal output from a sensor. SOLUTION: This sensor signal correction system is provided with a determination information storage means 34a for storing determination information for determining the presence of generation of a temperature difference between the sensor 21 and an attaching part for the sensor 21 in a vehicle, a start detecting means 31a for detecting start of a monitoring period for monitoring the generation of a predetermined temperature difference, and a reference value storage means 34b for storing as a reference value a value in response to the signal output from the sensor 21 corresponding to the start detected by the start detecting means 31a. The correction system is provided further with a temperature difference detecting means 31b for detecting the generation of the temperature difference, based on the signal output from the sensor 21 during the monitoring period and the judge-determination information stored in the determination information storage means 34a, and a correction means 31c for conducting correction to bring the signal corresponding to the detection into the reference value stored in the reference value storage means 34b, when the temperature difference detecting means 31b detects the generation of the temperature difference.
