What is P0487 : Engine Error code Causes Explained
This tutorial covers the P0487 engine problem code, its causes, and its fix. Exhaust gas recirculation (EGR) throttle control circuit issues can impair engine performance and emissions.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P0487 is related to the Exhaust Gas Recirculation (EGR) system, specifically indicating an issue with the EGR throttle control circuit.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
Identifying a DTC’s number requires an OBD-II scanner, which connects to the vehicle’s diagnostic port to retrieve error codes. Once scanned, the tool displays the DTC along with a brief description of the fault, helping in diagnosing the issue accurately.
Causes of P0487 Error Code:
- Faulty EGR valve:
Faulty EGR valve: improper exhaust gas regulation. - Damaged wiring or connectors:
EGR wiring issues: frayed, corroded, or loose connections. - EGR control solenoid failure:
The solenoid that controls the EGR valve may be faulty, preventing proper operation - Blocked EGR passages:
Carbon buildup in the EGR system can restrict the flow of exhaust gases. - Manifold Absolute Pressure (MAP) sensor malfunction:
The MAP sensor, essential tor PCM to calculate EUR operation, may be faulty.
Risk Level of P0487 Error Code:
A Medium Risk Level means the problem is not immediately critical but can worsen over time, affecting fuel efficiency and engine response. It’s advisable to diagnose and repair the issue soon to prevent further complications.

The P0487 engine error code is commonly found in the following list.
- Ford
- Mitsubishi
- Nissan
- Mercedes
- Volkswagen
- Chevrolet
- Dodge
- Suzuki
