What does code P1110 mean?

P1110 · MazdaIntake Air Temperature Sensor Signal Dynamic Chamber Circuit

P1110 on Mazda vehicles indicates that the powertrain control module (PCM) has detected an abnormal signal from the intake air temperature (IAT) sensor that is mounted in the dynamic chamber, which is the intake manifold resonance chamber. The PCM expects a voltage that corresponds to the actual air temperature, but the signal is out of range, intermittent, or implausible, so it sets this manufacturer-specific code.
