P062A

Symptoms

• The Check Engine light comes on
• Unstable fuel pressure
• Periodic failures during acceleration
• Increased noise of the fuel pump
• Unstable engine operation under load

Causes

• Fuel pump winding degradation (increased resistance)
• Pump filter screen clogged
• Unstable contact in the pump connector
• Pump control module degradation
• Low-quality fuel, which accelerates pump wear

How to Fix

1. Check the fuel pressure with a pressure gauge over time at different loads
2. Check the current consumption of the pump - compare with the norm
3. Check the pump connector - contacts, seal
4. Replace the fuel filter (if there is a replacement one)
5. Pump diagnostics with an oscilloscope - current analysis
6. If the pump degrades, replace the fuel pump
