OBD2 Code: P0215

Description: Fuel Injection Pump Control Circuit Malfunction

Definition: This code indicates that there is a problem with the electrical circuit controlling the fuel injection pump. The issue could be due to a faulty relay, wiring problems, or a malfunctioning fuel injection pump control module.

P0215 – Fuel Injection Pump Control Circuit

Typical Severity: Moderate

Common Causes

P0215 – Fuel Injection Pump Control Circuit

Description: The Engine Control Module (ECM) has detected a fault in the fuel injection pump control circuit.

Common Causes:

• Faulty fuel injection pump
• Wiring issues in the fuel injection pump control circuit
• Loose or corroded electrical connections related to the fuel injection pump
• Defective Engine Control Module (ECM)

 

Common Misdiagnosis

OBD2 Code: P0215

Description: Fuel Injection Pump Control Circuit Malfunction

Common Misdiagnosis: Replacing the fuel injection pump without checking the wiring and connectors for faults or issues with the engine control module (ECM).

 

Common Diagnostic Steps

OBD2 Code: P0215

Description: Fuel Injection Pump Control Circuit Malfunction

• Check for any blown fuses related to the fuel injection system and replace if necessary.
• Inspect the wiring and connectors in the fuel injection pump control circuit for signs of damage, corrosion, or disconnection. Repair or replace as needed.
• Test the voltage and ground signals at the fuel injection pump connector using a multimeter to ensure they are within specifications.
• Examine the fuel injection pump relay for proper operation and replace it if found faulty.
• Use an OBD2 scanner to clear the code and perform a test drive to see if it returns, indicating an intermittent issue.
• If all electrical components check out, consider testing or replacing the fuel injection pump itself as a last resort.
