Code P2019 Lincoln Description
The P2019 diagnostic trouble code for Lincoln vehicles specifically refers to an issue with the Intake Manifold Runner Position Sensor/Switch Circuit in Bank 2. This sensor is responsible for monitoring the position of the intake manifold runner, which controls the airflow into the engine. The intake manifold runner is a component that helps optimize the air-to-fuel ratio for better performance and fuel efficiency.
Common Causes of P2019 Lincoln
- Faulty Sensor: The most common cause of the P2019 code is a malfunctioning intake manifold runner position sensor.
- Wiring Issues: Problems with the wiring connecting the sensor to the ECM can also trigger this code.
- Corrosion: Corrosion on the sensor or wiring can disrupt the signal and cause the sensor to malfunction.
- Poor Connection: A loose or poor connection between the sensor and the ECM can lead to issues with the circuit.
- Electrical Problems: Any electrical issues within the sensor or switch circuit can also be a potential cause of this code.
Symptoms of P2019 Lincoln
- Check Engine Light: The most common symptom associated with the P2019 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Rough Idle: The engine may experience rough idling, shaking, or vibrating when the intake manifold runner position sensor is malfunctioning.
- Decreased Fuel Efficiency: A faulty sensor can lead to decreased fuel efficiency as the engine struggles to maintain the proper air-to-fuel ratio.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting due to incorrect adjustments made by the ECM based on faulty sensor data.
How to Fix P2019 Lincoln
- Diagnose the Issue: Use a diagnostic tool to read the code and pinpoint the exact cause of the problem.
- Inspect Sensor and Wiring: Check the intake manifold runner position sensor and wiring for any visible damage, corrosion, or loose connections.
- Replace Sensor: If the sensor is determined to be faulty, replace it with a new one following manufacturer guidelines.
- Repair Wiring: If wiring issues are detected, repair or replace the damaged wiring to ensure a proper connection.
- Clear Codes: After making the necessary repairs, clear the diagnostic trouble codes and test the vehicle to ensure the issue has been resolved.
Cost to Fix P2019 Lincoln
The cost of repairing the P2019 code for the Lincoln vehicle can vary depending on the specific cause of the issue and the price of parts and labor. Typically, the cost of replacing the intake manifold runner position sensor can range from $150 to $300, including parts and labor. Additional costs may be incurred if wiring repairs are necessary.

Frequently Asked Questions about P2019 Lincoln Code
What does the OBDII code P2019 mean for a Lincoln vehicle?
P2019 indicates an issue with the Intake Manifold Runner Position Sensor or Switch Circuit on Bank 2. This sensor monitors the position of the intake manifold runner to optimize airflow and engine performance.
What are the common symptoms of code P2019 in a Lincoln?
Symptoms may include reduced engine performance, poor fuel economy, rough idling, and the Check Engine Light being illuminated.
What causes the P2019 code to appear in a Lincoln?
Potential causes include a faulty intake manifold runner position sensor, damaged wiring or connectors, a stuck intake manifold runner, or carbon buildup in the intake manifold.
Is it safe to drive a Lincoln with the P2019 code active?
While the vehicle may still be drivable, ignoring this code can lead to reduced performance and fuel efficiency. Long-term operation may cause further damage to the intake manifold system.
How can the P2019 code be diagnosed?
Diagnosis typically involves inspecting the intake manifold runner sensor, checking for wiring or connector damage, testing sensor voltage, and scanning for additional related codes.
Can a dirty intake manifold cause the P2019 code?
Yes, carbon buildup or dirt in the intake manifold can restrict the movement of the runners, triggering this code.
How can the P2019 code be fixed in a Lincoln?
Repairs may involve replacing the intake manifold runner position sensor, cleaning the intake manifold, repairing damaged wiring, or replacing the intake manifold runner itself.
How much does it cost to fix the P2019 code on a Lincoln?
Repair costs vary, but replacing the intake manifold runner position sensor can range from $100 to $300, excluding labor. Cleaning or repairing the intake manifold may add to the cost.
Does the P2019 code affect both banks of the engine?
No, the P2019 code specifically relates to Bank 2, which is the side of the engine opposite Bank 1.
Can I clear the P2019 code without fixing the issue?
You can clear the code temporarily using an OBDII scanner, but the issue will likely return unless the underlying problem is addressed.
