P2487 Dodge Code - Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 5

Quick Answer

The P2487 diagnostic trouble code (DTC) for Dodge vehicles indicates a problem with the Exhaust Gas Temperature (EGT) Sensor Circuit High for Bank 2 Sensor 5. Common causes include Faulty EGT Sensor: The EGT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM, Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can disrupt the signal transmission, Exhaust Leaks: Leaks in the exhaust system near the EGT sensor can affect the temperature readings. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2487 Dodge Description

The P2487 diagnostic trouble code (DTC) for Dodge vehicles indicates a problem with the Exhaust Gas Temperature (EGT) Sensor Circuit High for Bank 2 Sensor 5. This sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. The EGT sensor provides crucial data to the engine control module (ECM) to optimize fuel delivery and emissions control. When the ECM detects that the signal from the EGT sensor is higher than normal for Bank 2 Sensor 5, it triggers the P2487 code.

Common Causes of P2487 Dodge

  1. Faulty EGT Sensor: The EGT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
  2. Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can disrupt the signal transmission.
  3. Exhaust Leaks: Leaks in the exhaust system near the EGT sensor can affect the temperature readings.
  4. ECM Malfunction: A problem with the engine control module could cause it to misinterpret the EGT sensor data.

Symptoms of P2487 Dodge

  1. Check Engine Light: The most common symptom of the P2487 code is the illumination of the Check Engine Light on the dashboard.
  2. Reduced Engine Performance: The vehicle may experience a decrease in power and acceleration due to incorrect fuel delivery.
  3. Poor Fuel Economy: An incorrect EGT reading can lead to inefficient fuel combustion, resulting in decreased fuel efficiency.
  4. Increased Emissions: The vehicle may produce higher emissions than usual due to improper fuel mixture.

How to Fix P2487 Dodge

  1. Diagnose the Issue: Use an OBD-II scanner to read the P2487 code and investigate the EGT sensor, wiring, and exhaust system for any visible damage.
  2. Replace EGT Sensor: If the sensor is faulty, replace it with a new one following the manufacturer's guidelines.
  3. Repair Wiring: Repair or replace any damaged wiring connecting the EGT sensor to the ECM.
  4. Fix Exhaust Leaks: Seal any leaks in the exhaust system near the EGT sensor to ensure accurate temperature readings.
  5. Reset ECM: Clear the code from the ECM using the OBD-II scanner and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P2487 Dodge

The cost of repairing the P2487 code for the Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 5 can vary depending on the extent of the issue and the specific parts needed. Typically, the cost of a new EGT sensor ranges from $50 to $200, while labor costs can be between $100 and $300. Overall, the total repair cost can range from $150 to $500. It's important to note that labor rates at auto repair shops can differ based on location, vehicle make and model, and the experience of the technicians.

Frequently Asked Questions about P2487 Dodge Code

1. What does the OBDII code P2487 mean on a Dodge vehicle?

P2487 indicates a high voltage issue in the exhaust gas temperature (EGT) sensor circuit for Bank 2, Sensor 5, which monitors exhaust temperatures to ensure proper emissions control.

2. What are the common symptoms of code P2487?

Common symptoms include an illuminated check engine light, reduced engine performance, poor fuel efficiency, or the vehicle entering limp mode.

3. What causes the P2487 code to appear?

Possible causes include a faulty EGT sensor, damaged wiring or connectors in the sensor circuit, a short circuit, or issues with the engine control module (ECM).

4. How can I diagnose the P2487 code?

Use a scan tool to confirm the code, inspect the wiring and connectors for damage, test the EGT sensor with a multimeter, and check for any related exhaust system issues.

5. Can I drive with the P2487 code?

While you may be able to drive with this code, it is not recommended as it could lead to increased emissions, reduced performance, or damage to the exhaust system over time.

6. How do I fix the P2487 code on my Dodge?

Fixes may include replacing the EGT sensor, repairing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.

7. How much does it cost to repair the P2487 code?

The cost depends on the specific issue, but replacing an EGT sensor typically costs $100-$300, while wiring repairs or ECM replacement can cost more.

8. Where is Bank 2, Sensor 5 located?

On a Dodge vehicle, Bank 2 refers to the side of the engine opposite cylinder 1, and Sensor 5 is further downstream in the exhaust system, often near or after the catalytic converter.

9. Can a faulty catalytic converter trigger the P2487 code?

While not a direct cause, a failing catalytic converter could indirectly lead to abnormal exhaust temperatures, potentially triggering the code.

10. What tools do I need to fix the P2487 code?

You’ll need an OBDII scanner, a multimeter for testing electrical circuits, and basic hand tools to replace the EGT sensor or repair wiring.
