P2087 Lincoln Code - Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 2

Quick Answer

The P2087 diagnostic trouble code for a Lincoln vehicle indicates a problem with the Exhaust Gas Temperature (EGT) sensor circuit on Bank 2 Sensor 2. Common causes include Faulty EGT Sensor: The most common cause of the P2087 code is a defective EGT sensor on Bank 2 Sensor 2, Wiring Issues: Corrosion, fraying, or damage to the wiring harness connected to the EGT sensor can cause intermittent signal disruptions, ECM Malfunction: A malfunctioning ECM can incorrectly interpret the signals from the EGT sensor, triggering the P2087 code. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P2087 Lincoln Description

The P2087 diagnostic trouble code for a Lincoln vehicle indicates a problem with the Exhaust Gas Temperature (EGT) sensor circuit on Bank 2 Sensor 2. This sensor is responsible for monitoring the exhaust gas temperature after the catalytic converter on the second bank of cylinders. The EGT sensor plays a crucial role in providing data to the engine control module (ECM) to adjust fuel delivery and optimize engine performance.

Common Causes of P2087 Lincoln

  1. Faulty EGT Sensor: The most common cause of the P2087 code is a defective EGT sensor on Bank 2 Sensor 2.
  2. Wiring Issues: Corrosion, fraying, or damage to the wiring harness connected to the EGT sensor can cause intermittent signal disruptions.
  3. ECM Malfunction: A malfunctioning ECM can incorrectly interpret the signals from the EGT sensor, triggering the P2087 code.
  4. Exhaust System Leaks: Leaks in the exhaust system can cause erroneous readings from the EGT sensor, leading to the code being triggered.
  5. Catalytic Converter Issues: Problems with the catalytic converter, such as clogs or damage, can affect the performance of the EGT sensor and trigger the code.

Symptoms of P2087 Lincoln

  1. Check Engine Light: The most common symptom associated with the P2087 code is the illumination of the Check Engine Light on the vehicle's dashboard.
  2. Reduced Fuel Efficiency: A malfunctioning EGT sensor can cause the engine to run inefficiently, leading to decreased fuel economy.
  3. Rough Idling: The vehicle may experience rough idling or hesitation when accelerating due to incorrect fuel delivery.
  4. Emissions Issues: A faulty EGT sensor can lead to increased emissions output, potentially causing the vehicle to fail emissions tests.
  5. Engine Misfires: In severe cases, the engine may experience misfires or rough running conditions as a result of improper fuel delivery.

How to Fix P2087 Lincoln

  1. Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the specific trouble code and verify the issue with the EGT sensor.
  2. Inspect Wiring: Check the wiring harness connected to the EGT sensor for any signs of damage, corrosion, or loose connections.
  3. Replace EGT Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor to ensure accurate readings.
  4. Clear Codes: After making the necessary repairs, clear the diagnostic trouble codes from the ECM memory to reset the system.
  5. Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the Check Engine Light does not reappear.

Cost to Fix P2087 Lincoln

The typical repair costs for addressing the P2087 code on a Lincoln vehicle can range from $150 to $400, depending on the specific cause of the issue and the cost of parts and labor. Additional costs may be incurred if other components, such as the wiring harness or ECM, need to be replaced. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate based on your location and vehicle model.
