Some vehicles may exhibit the CHECK ENGINE light on with DTC P011B:00 (Engine coolant temperature/IAT: Correlation error) when using an engine block heater which is set up by MCI as local accessory parts. Due to variation of block heater performance and environmental conditions against the SKYACTIV-G 2.5T engine, the PCM has difficulty detecting block heater operation. To eliminate this concern, the control software of the PCM has been modified to increase the margin for the block heater detection performance to the similar level as 2019 and later models.

TSB: Some 2015 model year Tacoma and 4Runner vehicles equipped with a 1GR-FE engine may exhibit a MIL "ON" condition with Diagnostic Trouble Code (DTC) P011B - Engine Coolant Temperature / Intake Air Temperature Correlation - when no part malfunction is present. The Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) logic has been modified to reduce the possibility of this condition occurring. Use the following repair procedure to address this condition.
