Q: What does code P2892 mean?

Cylinder 1 Ion Current Sense Circuit Low. P2892 indicates that the powertrain control module (PCM) has detected an abnormally low voltage on the ion current sense circuit for cylinder 1, which is used to measure combustion quality through ionization current. The PCM sets this code when the signal from the cylinder 1 ion current sensor falls below the expected threshold during engine operation.
