Diagnosis & Repair

WARNING: This page is about a different car, the 2003 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.
  1. If any other codes (besides DTC P2119) are being output, diagnose relevant DTC. If not, go to next step.
  2. Visually check throttle valve. Remove the intake air duct. Check whether or not a foreign body is caught between throttle valve and housing. Clean or replace throttle body as necessary. If okay, replace ECM.
