How is fault code P062A fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Pull the codes and the freeze-frame data so you can see what the engine was doing when it logged. P062A alongside a low fuel pressure code points you in a very different direction to P062A on its own 2. Get under the car and check the pump connector and the harness running to the tank. Unplug it, look for corrosion, spread or pushed-back pins, and a connector full of damp 3. Find and clean the fuel pump earth point. A bad earth throws this code regularly and costs nothing to put right 4. Back-probe the control circuit with a multimeter while a helper cranks, checking you're getting supply voltage and a clean command signal to the pump module 5. Hook up a fuel pressure gauge and confirm the pump is actually building and holding pressure. If pressure is fine, you're chasing an electrical or control gremlin, not a tired pump 6. Check for manufacturer service bulletins for your model, several makes have known connector and module updates for this code
