Some 2017 – 2018 model year Highlander Hybrid vehicles may exhibit a MIL “ON” condition with Diagnostic Trouble Code (DTC) P3190 (Poor Engine Power). This may occur when operating the vehicle in high altitude and high temperature conditions.
The engine control module/ECM (SAE Term: Powertrain Control Module/PCM) logic has been modified to reduce the possibility of this condition occurring. Follow the Repair Procedure in bulletin T-SB-0056-18 to address these conditions.
The repair is to reprogram the ECM with the updated calibration file 30E40100.
This repair is covered under the Toyota Federal Emission Warranty. This warranty is in effect for 96 months or 80,000 miles, whichever occurs first, from the vehicle’s in-service date.
