U0410 – Invalid Data Received From Fuel Pump Control Module

U0410 – Invalid Data Received From Fuel Pump Control Module means one or more control units in the vehicle—typically the ECM, BCM, or TCM—are detecting fuel-system data from the Fuel Pump Control Module (FPCM) that is out of range, inconsistent, or corrupt. Since the FPCM regulates fuel pump voltage, pressure, and delivery rate, incorrect data can cause hard starting, hesitation, reduced power, or even stalling. This guide explains what U0410 means, the symptoms to watch for, the most common causes, diagnosis steps, and effective repair solutions.

What Does U0410 Mean?

U0410 is a generic OBD-II U-code that sets when the ECM or another module receives invalid, corrupted, or contradictory fuel system data from the Fuel Pump Control Module. Unlike a lost-communication code, U0410 means the FPCM is still communicating, but the values being transmitted—such as fuel pump duty cycle, pressure feedback, or pump current—don’t make sense.

This may be triggered by wiring problems, low system voltage, faulty fuel pressure sensors, corrupted CAN packets, or internal faults within the FPCM. If the ECM cannot trust the fuel system data, the engine may enter limp mode or shut down to protect itself.

Real-World Example / Field Notes

A compact crossover arrived with long crank times and reduced power. The ECM stored U0410. Fuel pressure would briefly spike and drop intermittently. The root cause was a failing FPCM that intermittently sent invalid pump-duty-cycle values. Replacing the module immediately stabilized pressure.

Another case involved a sedan with hesitation under acceleration. U0410 appeared in both the ECM and TCM. The problem turned out to be a corroded ground at the rear body chassis where the FPCM was mounted. Cleaning and securing the ground restored accurate data readings.

Symptoms of U0410 – Invalid Data Received From Fuel Pump Control Module

  • Long crank or no start: ECM receives unreliable pressure data.
  • Hesitation or stumble on acceleration: Incorrect fuel pump output.
  • Reduced engine power: Engine may enter failsafe mode.
  • Surging or fluctuating idle: Inconsistent fuel pressure readings.
  • Stalling while driving: Pump command may drop unexpectedly.
  • Fuel pump running loud or irregular: FPCM driving pump erratically.
  • Other U-codes present: Network instability affecting multiple systems.

Common Causes of U0410

Most Common Causes

  • Failing fuel pump control module (FPCM)
  • Corroded ground or poor power supply to the FPCM
  • Faulty fuel pressure sensor sending invalid readings
  • CAN bus wiring faults (opens, shorts, water intrusion)
  • Low battery voltage or unstable alternator output

Less Common Causes

  • Internal ECM software glitch
  • Aftermarket fuel pump or wiring modifications
  • Damaged rear body harness (rodents, corrosion, road debris)
  • Failed CAN gateway or junction block
  • Water intrusion around FPCM mounting area

Diagnosis: Step-by-Step Guide

U0410 requires verifying the integrity of the fuel pump control system, wiring, and CAN network. Follow these steps for a proper diagnosis.

Tools You’ll Need

Advanced scan tool, multimeter, wiring diagrams, backprobe leads, fuel pressure gauge, Mode $06-capable scanner, and optional oscilloscope.

  1. Scan all modules: Note ECM, TCM, BCM, or ABS codes for related clues.
  2. Check battery and charging voltage: Low voltage is a common trigger.
  3. Inspect FPCM power and ground: Check for corrosion on chassis grounds and verify solid voltage supply.
  4. Review live fuel pressure data: Look for erratic or impossible values.
  5. Check physical fuel pressure: Compare sensor values with mechanical gauge readings.
  6. Inspect CAN wiring near FPCM: Look for damaged insulation or moisture intrusion.
  7. Backprobe fuel pressure sensor: Confirm stable reference voltage and signal output.
  8. Wiggle-test harness: Look for intermittent swaps in pressure readings or pump command.
  9. Update ECM/FPCM software: Many vehicles have TSBs for data validity issues.
  10. Oscilloscope CAN test: Check for noise, invalid packets, or a failing module flooding the bus.

Pro Tip: On many vehicles, the FPCM is located in the trunk or under the vehicle—areas highly prone to road salt corrosion and water intrusion. Always inspect grounds and connectors before assuming the module is faulty.

Possible Fixes & Repair Costs

  • Repair FPCM power or ground circuits: €40–€120
  • Replace fuel pressure sensor: €60–€180
  • Repair CAN wiring: €80–€300
  • Update ECM or FPCM software: €90–€180
  • Replace Fuel Pump Control Module: €200–€650+
  • Charging system repair: €120–€400

Can I Still Drive With U0410?

It depends on the severity of the fault. If fuel pressure is unstable, the vehicle may hesitate, lose power, or stall—making driving unsafe. Short trips may be possible if symptoms are mild, but continued driving risks sudden engine shutdown. U0410 should be diagnosed and repaired quickly to avoid further fuel system damage.

FAQ

Does U0410 mean the FPCM is bad?

Not always. Many cases are caused by poor grounds, low voltage, or faulty pressure sensors that send the wrong data.

Can U0410 cause stalling?

Yes. Invalid fuel pressure data can cause the ECM to reduce fuel delivery or shut down injectors.

Is U0410 dangerous?

Potentially. If fuel pressure drops unexpectedly, the engine may stall while driving.

Can U0410 be caused by a weak battery?

Absolutely. Unstable voltage can corrupt data coming from the FPCM.

Does U0410 always require a new FPCM?

No. Always check wiring, grounds, and the fuel pressure sensor before replacing the module.
