Code P2253 Lincoln Description
The P2253 code for a Lincoln vehicle indicates a problem with the O2 sensor negative current control circuit on Bank 1 Sensor 1. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring and adjusting the air-fuel mixture in the engine for optimal combustion efficiency. In this specific case, Bank 1 Sensor 1 refers to the O2 sensor located before the catalytic converter on the side of the engine with the number 1 cylinder.
Common Causes of P2253 Lincoln
- Faulty O2 sensor
- Wiring issues or shorts in the O2 sensor circuit
- Vacuum leaks
- Exhaust leaks
- ECM malfunction
Symptoms of P2253 Lincoln
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Check Engine Light illuminated
- Increased emissions
How to Fix P2253 Lincoln
- Diagnose the issue using an OBD-II scanner to confirm the P2253 code and pinpoint the exact cause.
- Inspect the wiring harness and connector for any damage or corrosion. Repair or replace as needed.
- Test the O2 sensor using a digital multimeter to check for proper voltage readings. Replace the sensor if it is faulty.
- Check for vacuum leaks or exhaust leaks that could be affecting the air-fuel mixture. Repair any leaks found.
- Clear the code with the OBD-II scanner after completing the repairs, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2253 Lincoln

Frequently Asked Questions about P2253 Lincoln Code
What does the OBD-II code P2253 mean for a Lincoln?
P2253 indicates an issue with the O2 Sensor Negative Current Control Circuit High on Bank 1 Sensor 1, meaning the oxygen sensor is detecting abnormally high voltage or current in its circuit.
What are the symptoms of code P2253 in a Lincoln?
Symptoms may include poor fuel efficiency, rough idling, hesitation during acceleration, an illuminated check engine light, and possible failure of an emissions test.
What causes the P2253 code to appear?
Common causes include a faulty O2 sensor, damaged wiring or connectors in the sensor circuit, a malfunctioning powertrain control module (PCM), or exhaust leaks near the sensor.
How do I diagnose the P2253 code on my Lincoln?
Diagnosis involves checking the O2 sensor and its wiring for damage, testing the sensor's voltage and current, inspecting for exhaust leaks, and performing a PCM scan to rule out other related issues.
Can a bad O2 sensor trigger the P2253 code?
Yes, a malfunctioning O2 sensor is one of the primary causes of the P2253 code, as it directly relates to the sensor's current control circuit.
Is it safe to drive with the P2253 code active?
Driving with the P2253 code is not recommended, as it can lead to poor engine performance, reduced fuel efficiency, and potentially cause damage to other components over time.
How can I fix the P2253 code on a Lincoln?
Repairs may include replacing the O2 sensor, repairing or replacing damaged wiring or connectors in the sensor circuit, fixing any exhaust leaks, or reprogramming or replacing the PCM if necessary.
Can an exhaust leak cause the P2253 code?
Yes, an exhaust leak near Bank 1 Sensor 1 can disrupt O2 sensor readings and trigger the P2253 code.
How much does it cost to fix the P2253 code?
Repair costs typically range from $150 to $400, depending on whether the issue is with the O2 sensor, wiring, or other related components.
Will clearing the code with a scanner permanently fix the issue?
No, clearing the code will temporarily remove the check engine light, but the underlying issue must be repaired to prevent the code from returning.
