4. Lexus LX P0341 FAQs
What causes code P0341 to trigger on a Lexus LX?
On the Lexus LX (3.4L Twin-Turbo V6 (V35A-FTS LX 600 409HP) / Hybrid 700h), P0341 is most frequently caused by Stretched timing chain or worn timing belt jumped one tooth or Failed Variable Valve Timing (VVT) actuator phaser or oil control valve (OCV).
Where is the OBD-II port located on my Lexus LX?
On the Lexus LX, the 16-pin DLC diagnostic connector is located Under driver steering column behind flip cap. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Lexus LX with code P0341?
No. Stretched timing chain or incorrect camshaft timing can cause catastrophic valve-to-piston contact. Given that P0341 carries a High severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
