Lexus ls430 p2757. Didn’t feel comfortable posting Make: Lexus Code: P2757 Definition: Torque Converter Clutch Pressure Control Solenoid Performance (Shift Solenoid Valve SLU) Description: The monitor will run whenever this DTC is not present. Apr 25, 2021 ยท Hi guys, Just bought a 2007 IS250 automatic with 100k miles on it. I have a 2006 Lexus is250 that is approaching 200k miles. Does anyone have experience with p2757 code on a 2005 ls430. trueI replaced the SLU solenoid to a brand new OEM one, did the trans service while I was there, did everything as specified. I’m considering doing the trans service/filter while I’m at it. After checking with a Snap-on diagnostic tool the P2757 code came up. SYSTEM DESCRIPTION The ECM uses the signals from the throttle position sensor and air−flow meter to monitor the engagement condition of the lock− up clutch. Even when the code is active. This could be due to a faulty solenoid, problems with the control module, or wiring issues. 2or7sgw6q7z6bqqtcedrqbbt9m0uyglhbikxyaiwth
