What are the common causes of P0258 ?

• Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.
• Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
• Fuel with a large percentage of sulfur will clog the DPF quickly

How do you troubleshoot P0258 ?

• Replace the fuel injection pump
• Clear codes and road tests the vehicle to verify the code does not return
• Replaces the fuel filter and contaminated fuel before the injection pump is replaced
• Repairs or replaces the battery power supply to the injection pump circuit
