Code P164B Lincoln Description
The P164B diagnostic trouble code (DTC) for Lincoln vehicles specifically refers to an issue with the O2 sensor positive current trim circuit performance in bank 2 sensor 1. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the amount of oxygen present in the exhaust gases of the vehicle. This information is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion and emissions control.
Common Causes of P164B Lincoln
- Faulty O2 sensor
- Wiring or connector issues in the O2 sensor circuit
- ECM software or hardware problems
- Exhaust system leaks or damage
- Contaminated fuel affecting sensor readings
Symptoms of P164B Lincoln
- Decreased fuel efficiency
- Rough idling or stalling
- Check Engine Light illuminated
- Reduced engine power
- Increased emissions
How to Fix P164B Lincoln
- Diagnose the specific issue using a scan tool to pinpoint the exact cause of the code.
- Inspect the O2 sensor wiring and connectors for any damage or corrosion.
- Test the O2 sensor's functionality using a multimeter to ensure it is sending accurate readings.
- Replace the O2 sensor if it is found to be faulty.
- Clear the code and perform a test drive to verify that the issue has been resolved.
Cost to Fix P164B Lincoln

Frequently Asked Questions about P164B Lincoln Code
What does the OBDII code P164B mean on a Lincoln?
P164B indicates an issue with the O2 Sensor Positive Current Trim Circuit Performance for Bank 2, Sensor 1. It means the oxygen sensor isn't performing as expected within the current trim parameters.
What are the common symptoms of code P164B on a Lincoln?
Symptoms may include the Check Engine Light turning on, poor fuel efficiency, rough idling, reduced engine performance, and possibly increased exhaust emissions.
What causes the P164B code on a Lincoln?
Common causes include a faulty oxygen sensor, damaged wiring or connectors in the O2 sensor circuit, a malfunctioning PCM (Powertrain Control Module), or exhaust leaks near the sensor.
How do I diagnose the P164B code?
Start with a visual inspection of the O2 sensor wiring and connectors for damage. Use a diagnostic scan tool to monitor live data from the O2 sensor and test the circuit for proper voltage and current.
Can I drive my Lincoln with the P164B code?
While the vehicle may still be drivable, it's not advised to ignore the issue. Driving with this code can lead to increased fuel consumption, higher emissions, and potential damage to other engine components.
How do I fix the P164B code on a Lincoln?
Repairs may include replacing the faulty O2 sensor, repairing or replacing damaged wiring or connectors, addressing any exhaust leaks, or reprogramming or replacing the PCM if necessary.
How much does it cost to repair the P164B code?
The repair cost depends on the root cause. Replacing an O2 sensor can range from $150 to $400, while wiring repairs or PCM replacement may cost more depending on labor and parts.
Can a dirty air filter cause the P164B code?
A dirty air filter typically does not cause this specific code, but it can contribute to poor engine performance. It's still a good idea to check and replace the air filter if needed.
Is the P164B code specific to Lincoln vehicles?
While the P164B code may appear on other vehicle makes, its exact definition and troubleshooting steps are specific to Lincoln or Ford vehicles.
Can a bad catalytic converter trigger the P164B code?
A failing catalytic converter is not a direct cause of the P164B code but can affect exhaust flow, impacting O2 sensor performance and potentially contributing to the issue.
