P1287 Chrysler Code - Fuel Injection Pump Controller Supply Voltage Low Condition
Quick Answer
The P1287 code indicates a low supply voltage condition detected by the fuel injection pump controller in Chrysler vehicles. Common causes include Faulty Fuel Pump: A malfunctioning fuel pump may not draw adequate voltage, leading to low supply voltage conditions, Wiring Issues: Damaged or corroded wiring in the fuel pump circuit can impede the flow of electricity, Bad Fuel Pump Relay: A failing relay may not provide sufficient voltage to the fuel pump controller. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1287 Chrysler Description
The P1287 code indicates a low supply voltage condition detected by the fuel injection pump controller in Chrysler vehicles. This code is primarily associated with the fuel system's electronic control module (ECM) and the fuel injection pump's operation. When the supply voltage to the fuel injection pump controller drops below the manufacturer's specified threshold, the ECM triggers this diagnostic trouble code (DTC) to alert the driver or technician of the issue.
Common Causes of P1287 Chrysler
- Faulty Fuel Pump: A malfunctioning fuel pump may not draw adequate voltage, leading to low supply voltage conditions.
- Wiring Issues: Damaged or corroded wiring in the fuel pump circuit can impede the flow of electricity.
- Bad Fuel Pump Relay: A failing relay may not provide sufficient voltage to the fuel pump controller.
- Weak Battery: A battery that is not holding a charge properly can lead to low voltage conditions throughout the vehicle.
- Poor Electrical Connections: Loose or corroded connectors in the fuel pump circuit can disrupt voltage supply.
Symptoms of P1287 Chrysler
- Engine Stalling: The vehicle may stall unexpectedly, particularly during acceleration or when idling.
- Difficulty Starting: The engine may crank but fail to start, indicating insufficient fuel delivery.
- Poor Acceleration: The vehicle may exhibit sluggish performance or hesitation during acceleration.
- Check Engine Light: The illumination of the check engine light on the dashboard, often accompanied by the P1287 code.
- Increased Fuel Consumption: The vehicle may experience a noticeable drop in fuel efficiency due to improper fuel delivery.
How to Fix P1287 Chrysler
- Inspect Wiring and Connectors: Begin by visually inspecting the wiring and connectors associated with the fuel pump and controller for signs of damage, corrosion, or loose connections.
- Test Voltage Supply: Use a multimeter to check the voltage at the fuel pump connector while the engine is running to determine if the voltage is within the specified range.
- Replace Faulty Components: If any damaged wiring, connectors, or a faulty fuel pump relay is identified, replace them with OEM or high-quality aftermarket parts.
- Check the Fuel Pump: If the voltage supply is adequate but the pump is not functioning, consider testing or replacing the fuel pump itself.
- Clear Codes and Test Drive: After repairs, clear the DTCs using a scan tool and perform a test drive to ensure the issue has been resolved and the P1287 code does not return.
Cost to Fix P1287 Chrysler
The cost to diagnose and repair a P1287 code can vary widely based on location, vehicle make and model, and engine type. On average, the total repair costs can range from $150 to $600. This estimate typically includes parts and labor. Common parts that may need replacement include the fuel pump relay, wiring harness, or the fuel pump itself, which can range from $50 to $300 depending on the specific component and vehicle model.
