P0037 2017 Ford F150 Code - HO2S Heater Control Circuit Low 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 P0037 2017 Ford F150 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 P0037 2017 Ford F150?
- 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
How to Fix the DTC P0037 2017 Ford F150?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0037 2017 Ford F150 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0037 2017 Ford F150 Code
What does the OBDII code P0037 mean for a 2017 Ford F150?
P0037 indicates an issue with the heater control circuit for the downstream oxygen sensor (Bank 1 Sensor 2), specifically a low voltage condition.
What are the symptoms of code P0037 on a 2017 Ford F150?
Common symptoms include an illuminated check engine light, slightly reduced fuel efficiency, and potential difficulty passing an emissions test.
What causes the P0037 code to appear?
The most common causes include a faulty downstream oxygen sensor, damaged wiring or connectors in the heater circuit, or a malfunctioning powertrain control module (PCM).
How do I locate Bank 1 Sensor 2 on my 2017 Ford F150?
Bank 1 Sensor 2 is the oxygen sensor located downstream (after the catalytic converter) on the same side as cylinder 1.
Can I drive my 2017 Ford F150 with the P0037 code?
Yes, you can drive the vehicle, but it is recommended to address the issue promptly to avoid potential damage to the catalytic converter and decreased fuel efficiency.
How can I fix the P0037 code on my 2017 Ford F150?
Start by inspecting the wiring and connectors for damage or corrosion. If no issues are found, replacing the downstream oxygen sensor (Bank 1 Sensor 2) is often necessary.
How do I test the heater circuit for Bank 1 Sensor 2?
Use a multimeter to check the resistance of the oxygen sensor's heater circuit. If the resistance is out of spec, the sensor may need to be replaced.
Can a blown fuse cause the P0037 code on a 2017 Ford F150?
Yes, a blown fuse in the oxygen sensor heater circuit can cause the code by interrupting power to the sensor.
Does a bad PCM cause the P0037 code?
While rare, a malfunctioning PCM could cause the P0037 code. However, this is typically diagnosed after ruling out wiring and sensor issues.
How much does it cost to fix P0037 on a 2017 Ford F150?
Repair costs vary but typically range from $150 to $300, depending on whether only the sensor needs replacement or additional wiring repairs are required.
