P062A Problem in the fuel pump control circuit, range or performance

Fuel pump A control circuit range/performance

P062A in short

P062A means the computer saw the fuel pump A control circuit outside its expected range or performance. Owners with it report stalling and limp mode, and dealers replaced the fuel pump on a Giulia. Have it scanned soon and avoid driving if the engine stalls.

Many modern fuel systems have the computer control the fuel pump through a driver or module rather than switching power directly. P062A is set when the computer sees the pump A control circuit outside the expected range or performance.

The complaints read describe a pattern: a 2016 Ram 1500 owner's scan reads 'circuit A fuel pump range/performance'; two Alfa Romeo Giulia owners report P062A with P008A (fuel pump related) and a fuel pump replacement on the 2018 car, with limp mode or a highway stall.

A repair is not guaranteed by fuel pump replacement. A 2019 Ram owner reports the code returned after the fuel pump was replaced, and the 2016 Ram owner's dealer fixed a connector behind the driver wheel and the code still returned. The wiring and the pump control path need testing before parts.

Most likely causes

  1. Fuel pump or its driver output

    Supported by vehicle data
    Why it ranks here
    A 2018 Giulia's technicians reported P062A and P008A as a fuel pump issue and replaced the fuel pump. A 2017 Giulia owner reports the same pair 'point to a fuel pump error'. On a 2019 Ram the code came back after a pump replacement, so this is not a sure fix.
    What would change this
    Rises if fuel pressure is low or the pump does not respond when commanded. Falls if pressure and pump response are normal.

  2. Wiring or connector in the pump control circuit

    Possible — needs testing
    Why it ranks here
    On the 2016 Ram the dealer replaced a connector behind the driver wheel; the code and the check engine light returned, so the circuit is worth testing but is not proven as the cause.
    What would change this
    Rises if voltage drop or continuity testing finds a poor connection. Falls if the circuit tests good under load.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read all stored codes and freeze-frame data and note whether P008A, P0087 or U0415 are stored with P062A.

    Low riskTool: OBD-II scan tool

  2. Have a shop measure fuel pressure and check the pump's commanded and actual output.

    Best left to a shopTool: fuel pressure gauge, bidirectional scan tool

    Warning:Fuel is under pressure and flammable. A leak near hot parts can start a fire; let a shop relieve pressure and connect gauges.

Symptoms

  • Check engine light with reduced power or limp mode
  • Hesitation or loss of power under load
  • Engine stalls at highway speed and may not restart Gets more serious: stop and have it checked.

How to fix

  1. Have a shop read all codes, including any fuel pump or pressure codes stored with P062A, before replacing the pump.

Parts and cost context

  • Fuel pump:A pump replacement fixed one Giulia but not a Ram where the code returned. Confirm fuel pressure and wiring first; labour varies, get a quote.

Labor varies by vehicle and shop; get a quote before you approve a repair.

Ram

  • 2016–2019 · 1500

    Supported by vehicle data

    A 2016 owner's scan reads P062A as 'circuit A fuel pump range/performance'; a connector repair did not clear it. A 2019 owner reports stalling and the code returning after a fuel pump replacement. Complaints only, not verified by NHTSA.

  • P008APressure in the low-pressure fuel system (lift pump side) is too low

    Shares causes Supported by vehicle data

    Two Giulia owners had P008A (low fuel pressure, low-pressure system) stored with P062A; both point at the fuel pump.

  • P0087Fuel pressure in the rail or supply system is lower than the engine computer requested

    Shares causes Possible — needs testing

    A 2017 Giulia stored P0087 (fuel rail pressure too low) with P062A and P008A.

P062A questions

Is it safe to drive with P062A?

It can stall the engine at speed, as Giulia and Ram owners report. Get it checked soon and do not keep driving if the engine stalls.

Should I just replace the fuel pump?

Not first. The code came back on a 2019 Ram after a pump replacement. Test fuel pressure and the control wiring before buying parts.
