2A13 DMTL Code fuel pump

Naser,

Can you provide the P code for this? The OEM 2A13 is vague and can point in three different directions. I need to know if it is a P2400, P2401, or a P2402. One is indicating an evap leak the other two are specific to low or high voltage to the pump.

Let me know.

Hi,

They expect the pump operation to be tested when you actuate it. However, the pump may work but still be drawing too much amperage. In most cases, either the pump has an internal fault or there is a wiring issue, a short to power.

If there is no evidence of wiring damage, corrosion, or damage at the connector, the only other thing you can do is first confirm that it is drawing greater than 10v. If it is, then check resistance at the pump motor, and for some reason, I don't have the resistance specs. But, if there are no wiring issues causing a high voltage draw, then in most cases, the pump itself is bad.

I hope that makes sense. Also, I checked N52 and it's the same. Somewhere you have a short to power drawing too much voltage/terminal 15. If there are no wiring issues, I would replace the pump.

Let me know if this helps. Also, I tried to find resistance for you, but neither manual has it.
