3. Step-by-Step Fix Protocol for Tesla
Listen for exhaust ticking or black soot around flex pipe, flanges, and sensor bungs before the catalytic converter. on Tesla engines.
Monitor B1S2 voltage. Snap the throttle to enrich mixture; voltage should briefly spike above 0.8V. If it remains 0.0V–0.1V, sensor is defective or shorted. on Tesla engines.
Unplug harness, remove old sensor with 7/8 socket, install replacement sensor and plug firmly. on Tesla engines.
Clear DTCs and verify B1S2 holds steady between 0.45V and 0.75V during steady highway cruising. on Tesla engines.

4. Tesla P0137 Frequently Asked Questions
What does code P0137 mean on a Tesla?
On Tesla vehicles, P0137 indicates that the Engine Control Module (ECM) detected o2 sensor circuit low voltage (bank 1 sensor 2). This typically points to Exhaust leak upstream of or directly at the Sensor 2 bung letting in fresh air or Faulty downstream oxygen sensor.
Can I continue driving my Tesla with code P0137?
Yes. Vehicle is fully drivable, but Check Engine Light will remain illuminated. Because this code carries a Low severity rating on Tesla powertrains, we recommend scanning live data values promptly to prevent secondary damage.
How much does it cost to fix code P0137 on a Tesla?
Estimated DIY parts cost ranges from $100 - $300 (DIY: $35 - $100), while professional shop repairs at an authorized Tesla dealership or independent specialist typically range from $180 to $380 including diagnostic labor.
