The car's computer is saying that a part that helps control pollution isn't working right. It's like a sensor that tells the car how much gas to let back into the engine to make it cleaner, but it's not getting enough power.
The EGR (Exhaust Gas Recirculation) system helps reduce emissions by recirculating a portion of the exhaust gases back into the engine cylinders. This code indicates that the sensor monitoring this process is not receiving enough voltage.
The P2387 code is triggered when the Engine Control Module (ECM) detects a low voltage condition in the EGR Sensor E circuit. This sensor is responsible for providing feedback about the EGR valve's position, ensuring the correct amount of exhaust gas is recirculated. A low voltage signal may indicate a wiring issue, a faulty sensor, or a problem with the ECM itself.
• Check Engine Light illuminated
• Poor engine performance
• Increased emissions
• Faulty EGR sensor
• Wiring issues (e.g., damaged wires or poor connections)
• Faulty Engine Control Module (ECM)
EGR: Exhaust Gas Recirculation
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the EGR sensor and its wiring for damage.
• Test the voltage at the EGR sensor connector.
• Replace the faulty EGR sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdrivers

• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance and inspection of the EGR system.
• Ensure all electrical connections are secure.
• Use high-quality fuel to prevent carbon buildup.
Sensor Issue
• Do not ignore the Check Engine Light.
• Seek professional diagnostic assistance if unsure.
• Regularly maintain your vehicle to avoid similar issues.
Check with your vehicle's manufacturer for warranty coverage on emissions-related components.
The P2387 code is relatively uncommon and often linked to specific vehicle models with known EGR sensor issues.
Moderate – While the vehicle may still be drivable, emissions and performance may be affected.
Driving with a malfunctioning EGR system may lead to increased emissions, which can be illegal in some areas.
• Engine at operating temperature
• Vehicle at idle or under light load
The EGR sensor is typically located near the EGR valve, which is mounted on or near the intake manifold.
Q: Can I drive with a P2387 code?
A: While you can drive with this code, it's best to get it fixed soon to avoid increased emissions and potential engine performance issues.
Q: How can I reset the Check Engine Light after fixing the issue?
A: You can use an OBD-II scanner to clear the code, or the light may turn off automatically after a few drive cycles if the problem is resolved.
