4. Tesla Model X P0452 FAQs
What causes code P0452 to trigger on a Tesla Model X?
On the Tesla Model X (Dual Motor AWD / Tri-Motor Plaid (1,020 HP Falcon Wing Doors)), P0452 is most frequently caused by Faulty Fuel Tank Pressure (FTP) sensor or Short to ground in sensor signal wire.
Where is the OBD-II port located on my Tesla Model X?
On the Tesla Model X, the 16-pin DLC diagnostic connector is located Driver side lower instrument panel trim. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Tesla Model X with code P0452?
Yes. Fuel tank pressure sensor shorted to ground. Given that P0452 carries a Low severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
