3. Step-by-Step DIY Repair Guide for Tesla Model S
Locate Cylinder 1 fuel injector. Ensure connector is securely clicked in and wires are not frayed. on the Tesla Model S equipped with Dual Motor AWD / Tri-Motor Plaid (1,020 HP / 0-60 in 1.99s).
Unplug connector and measure resistance across the two injector pins. Normal is 11–16 ohms for high-impedance injectors. If open (OL) or shorted (0 ohms), replace injector. on the Tesla Model S equipped with Dual Motor AWD / Tri-Motor Plaid (1,020 HP / 0-60 in 1.99s).
Plug a noid light into the harness connector and crank engine. Rapid flashing confirms PCM driver is pulsing the circuit. on the Tesla Model S equipped with Dual Motor AWD / Tri-Motor Plaid (1,020 HP / 0-60 in 1.99s).
Relieve fuel rail pressure, unbolt fuel rail mounting bolts, gently pull rail up, remove retaining clip, and replace Cylinder 1 injector with new OEM unit with lubricated O-rings. on the Tesla Model S equipped with Dual Motor AWD / Tri-Motor Plaid (1,020 HP / 0-60 in 1.99s).
Turn key to ON to prime fuel system, check for fuel rail leaks, start engine, clear DTCs, and verify smooth idle. on the Tesla Model S equipped with Dual Motor AWD / Tri-Motor Plaid (1,020 HP / 0-60 in 1.99s).

4. Tesla Model S P0201 FAQs
What causes code P0201 to trigger on a Tesla Model S?
On the Tesla Model S (Dual Motor AWD / Tri-Motor Plaid (1,020 HP / 0-60 in 1.99s)), P0201 is most frequently caused by Failed, open, or shorted fuel injector solenoid on Cylinder 1 or Damaged or chewed wiring harness to Cylinder 1 injector.
Where is the OBD-II port located on my Tesla Model S?
On the Tesla Model S, the 16-pin DLC diagnostic connector is located Under center dash / driver kick panel bulkhead. 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 S with code P0201?
No. Dead injector on Cylinder 1 causes immediate dead misfire, severe shaking, and unburned air/fuel delivery imbalance. Given that P0201 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
