P1450 Cadillac Code - Barometric Pressure Sensor Circuit
Quick Answer
With the key on for 2 seconds or engine cranked for 2 seconds, the Powertrain Control Module (PCM) detects that the BARO Pressure sensor input was less than 33 kPa, or was more than 134 kPa, or during the Input Range Check, that the BARO Pressure sensor indicated an input greater than or equal to 135 kPa, condition met for 2 seconds. Common causes include Faulty Barometric Pressure Sensor, Barometric Pressure Sensor harness is open or shorted, Barometric Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
