P1487 Mazda Code - EGR Boost Sensor Solenoid Valve Open or Short
Quick Answer
The P1487 diagnostic trouble code (DTC) for Mazda vehicles relates to a malfunction in the Exhaust Gas Recirculation (EGR) Boost Sensor Solenoid Valve. Common causes include Faulty EGR Boost Sensor Solenoid Valve: The most common cause of a P1487 code is a malfunction in the EGR Boost Sensor Solenoid Valve itself, Wiring Issues: Electrical problems such as damaged wiring, loose connections, or short circuits can also trigger this code, EGR System Blockage: Blockages or restrictions in the EGR system can disrupt the flow of exhaust gases, leading to EGR system malfunctions. 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 P1487 Mazda Description
The P1487 diagnostic trouble code (DTC) for Mazda vehicles relates to a malfunction in the Exhaust Gas Recirculation (EGR) Boost Sensor Solenoid Valve. The EGR system is responsible for recirculating a portion of the engine's exhaust gases back into the intake manifold to reduce nitrogen oxide emissions. The EGR Boost Sensor Solenoid Valve plays a crucial role in regulating the EGR system by controlling the flow of exhaust gases.
Common Causes of P1487 Mazda
- Faulty EGR Boost Sensor Solenoid Valve: The most common cause of a P1487 code is a malfunction in the EGR Boost Sensor Solenoid Valve itself.
- Wiring Issues: Electrical problems such as damaged wiring, loose connections, or short circuits can also trigger this code.
- EGR System Blockage: Blockages or restrictions in the EGR system can disrupt the flow of exhaust gases, leading to EGR system malfunctions.
- Carbon Buildup: Accumulation of carbon deposits in the EGR system can hinder the proper operation of the solenoid valve.
- ECU Malfunction: A malfunction in the engine control unit (ECU) or onboard computer can also cause the EGR Boost Sensor Solenoid Valve to open or short, triggering the P1487 code.
Symptoms of P1487 Mazda
- Check Engine Light: The most common symptom associated with a P1487 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Rough Idling: The engine may experience rough idling or unstable RPMs due to the improper operation of the EGR system.
- Reduced Power: The vehicle may exhibit a lack of power or responsiveness when accelerating, especially at higher speeds.
- Increased Emissions: A malfunctioning EGR system can lead to higher emissions output, potentially causing the vehicle to fail emissions tests.
- Poor Fuel Economy: A P1487 code can result in decreased fuel efficiency as the engine struggles to operate efficiently with a faulty EGR system.
How to Fix P1487 Mazda
- Diagnose the Issue: Begin by using an OBD-II scanner to retrieve the P1487 code and verify the EGR Boost Sensor Solenoid Valve's operation.
- Inspect Wiring and Connections: Check the wiring harness and connections associated with the solenoid valve for any damage or corrosion. Repair or replace as needed.
- Clean EGR System: Remove any carbon buildup or blockages in the EGR system that may be hindering the valve's operation.
- Replace EGR Boost Sensor Solenoid Valve: If the solenoid valve is found to be faulty, replace it with a new, OEM-approved part to restore proper EGR system function.
- Clear Codes and Test Drive: Clear the P1487 code from the vehicle's computer memory, then test drive the vehicle to ensure that the issue has been resolved and the Check Engine Light remains off.
Cost to Fix P1487 Mazda
The cost of repairing a P1487 code can vary depending on the vehicle make and model, the location of the repair shop, and the specific cause of the issue. On average, the parts cost for a new EGR Boost Sensor Solenoid Valve can range from $50 to $150, while the labor cost for the repair may be between $100 and $200. Therefore, the total repair cost for addressing a P1487 code could be in the range of $150 to $350. It's important to note that additional diagnostic time and labor charges may apply, so it's recommended to consult with a trusted auto repair shop for a more accurate cost estimate.
