Toyota 89665-04013 Engine Control Calibration
Explore Toyota calibration 89665-04013, its Tacoma engine control module role and its connection to diagnostic code P261093.
Toyota 89665-04013 is an engine control module calibration associated with the full calibration ID 896650401300. Toyota service records identify it as an updated ECM calibration in bulletins covering the 2016 and 2017 Tacoma.
The ECM manages engine operation by processing sensor inputs and controlling functions such as fuel delivery and ignition timing. Its calibration provides the settings and logic the controller uses to run the engine and monitor its performance. The general role of the ECM does not, by itself, establish which of those settings changed in this revision.
Malfunction indicator light and P261093
Toyota service bulletin T-SB-0013-19 lists 896650401300 as an updated calibration in connection with a malfunction indicator light and diagnostic trouble code P261093. In practical terms, the bulletin concerns an engine-management warning that may illuminate the check-engine light and leave a diagnostic code for a technician to investigate.
The bulletin covers several Toyota models and model years. That broad scope does not mean this particular calibration fits every vehicle listed in the bulletin.
Tacoma service record context
Toyota also lists the calibration as updated in T-SB-0077-16 and T-TCI-4419, both of which identify the engine control module and cover 2016 and 2017 Tacoma vehicles. T-SB-0062-18 lists it as updated within a bulletin covering 2016 through 2018 Tacoma models.
In T-SB-0125-18, the same full ID appears in both previous and updated calibration entries. Those labels describe its position in the bulletin's calibration listings, rather than a single, universal revision history for every Tacoma.
