4. Lincoln P0136 Frequently Asked Questions

What does code P0136 mean on a Lincoln?

On Lincoln vehicles, P0136 indicates that the Engine Control Module (ECM) detected o2 sensor circuit malfunction (bank 1 sensor 2). This typically points to Failing downstream O2 sensor element or Corroded or road-damaged downstream sensor wiring underneath vehicle.

Can I continue driving my Lincoln with code P0136?

Yes. Sensor 2 is downstream of the catalytic converter and monitors catalyst efficiency rather than air-fuel mixture. Because this code carries a Low severity rating on Lincoln powertrains, we recommend scanning live data values promptly to prevent secondary damage.

How much does it cost to fix code P0136 on a Lincoln?

Estimated DIY parts cost ranges from $100 - $300 (DIY: $35 - $100), while professional shop repairs at an authorized Lincoln dealership or independent specialist typically range from $180 to $380 including diagnostic labor.
