What does code P01BA mean?

Q: What does code P01BA mean?

Engine Oil Temperature Sensor B Range/Performance. P01BA means the powertrain control module (PCM) has detected that the signal from engine oil temperature sensor B is outside the expected range or is not behaving rationally compared to other temperature inputs. The PCM compares this sensor's reading against a plausible range and against other temperature sensors after a cold start, and it sets the code when the correlation or performance check fails.
