P0036 Lincoln Code - HO2S Heater Control Circuit Bank 1 Sensor 2
Quick Answer
The HO2S detects the presence of oxygen in the exhaust and produces a variable voltage according to the amount of oxygen detected. Common causes include Faulty Heated Oxygen Sensor Bank 1 Sensor 2 (HO2S12), Heated Oxygen Sensor Bank 1 Sensor 2 circuit open shorted to ground, Heated Oxygen Sensor Bank 1 Sensor 2 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0036 Lincoln Description
When the oxygen sensor is cold, disconnected, or on initial start-up, the voltage may read between 1.5 to 1.7 volts. The oxygen sensor voltage will decrease to the normal operating range of 0.0 to 1.1 volts during warm, stabilized engine running conditions.
The HO2S heater is embedded with a sensing element. The heating element heats the sensor to a temperature of 800°C (1,472°F). At approximately 300°C (572°F) the engine enters closed loop operation. The heater allows the engine to enter closed loop operation sooner.
The PCM controls the Heated Oxygen Sensor Bank 1, Sensor 2 (HO2S12) heater ON and OFF duty cycle to maintain a calibrated temperature. This Diagnostic Trouble Code (DTC) is set when the sensor does not warm up to the required temperature in a calibrated amount of time. This DTC is also set when the PCM is not able to maintain the required temperature after the sensor is warmed.
What are the Possible Causes of the DTC P0036 Lincoln?
- Faulty Heated Oxygen Sensor Bank 1 Sensor 2 (HO2S12)
- Heated Oxygen Sensor Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor Bank 1 Sensor 2 circuit poor electrical connection

Frequently Asked Questions about P0036 Lincoln Code
What does the OBDII code P0036 mean on a Lincoln?
P0036 indicates an issue with the HO2S (Heated Oxygen Sensor) Heater Control Circuit for Bank 1 Sensor 2, meaning the heater element is not functioning properly.
What are the symptoms of code P0036 on a Lincoln?
Common symptoms include the check engine light being illuminated, reduced fuel efficiency, and possibly failing an emissions test, although there may be no noticeable driving issues.
What causes the P0036 code to appear on a Lincoln?
Typical causes include a faulty oxygen sensor, damaged wiring or connectors, a blown fuse, or a malfunctioning powertrain control module (PCM).
How do I diagnose the P0036 code on my Lincoln?
Begin by inspecting the wiring and connectors to the Bank 1 Sensor 2 oxygen sensor, check for blown fuses, and test the oxygen sensor's heater circuit for continuity using a multimeter.
Can a P0036 code damage my Lincoln if left unrepaired?
While the code itself is unlikely to cause immediate damage, ignoring it can lead to poor fuel economy and increased emissions, potentially causing long-term wear on the catalytic converter.
How can I fix the P0036 code on a Lincoln?
Repairs may include replacing the faulty oxygen sensor, repairing damaged wiring or connectors, replacing a blown fuse, or, in rare cases, reprogramming or replacing the PCM.
Is P0036 related to a specific oxygen sensor on a Lincoln?
Yes, it specifically refers to the heater control circuit for Bank 1 Sensor 2, which is the downstream oxygen sensor on the same side as cylinder 1.
How much does it cost to repair the P0036 code on a Lincoln?
Costs vary but typically range from $150 to $300 for parts and labor if replacing the oxygen sensor. Wiring or PCM repairs may cost more depending on the issue.
Can I drive my Lincoln with a P0036 code?
While it’s generally safe to drive for a short period, it’s best to address the issue promptly to avoid worsening fuel efficiency and emissions problems.
Does clearing the P0036 code fix the issue on a Lincoln?
Clearing the code will turn off the check engine light temporarily, but if the underlying issue isn’t resolved, the code will return.
