DESCRIPTION The skid control ECU (brake actuator assembly) stores this DTC when the previously learned values in the VSC system and engine information sent from the ECM are inconsistent, or when the learning has not completed after the skid control ECU (brake actuator assembly) is replaced with a new one.
CAUTION / NOTICE / HINT NOTICE: When replacing the skid control ECU (brake actuator assembly), perform system variant learning and acceleration sensor zero point calibration. Click here PROCEDURE
(a) Check if the ECM or brake actuator assembly had been replaced before the DTC was recorded.

Toyota Tundra Service Manual > Sfi System: Oxygen (A/F) Sensor Signal Stuck Lean (Bank 1 Sensor 1) (P2195-P2198)
DESCRIPTION The A/F sensor generates a voltage* that corresponds to the actual air-fuel ratio. This sensor voltage is used to provide the ECM with feedback so that it can control the air-fuel ratio. The ECM determines the deviation from the stoichiometric air-fuel ratio, and regulates the fuel injec ...
