Fuel Pump Control Circuit Range/Performance
The P062A code indicates that the Engine Control Module (ECM) has detected a malfunction in the fuel pump control circuit, specifically a range or performance issue. This means the fuel pump is not operating within its expected parameters, such as voltage, current, or speed. The fuel pump control module (FPCM) or the ECM monitors the pump's performance and sets this code when the actual performance deviates from the commanded performance. This can lead to insufficient fuel pressure, causing drivability issues.
01. Most Common Causes
- Faulty fuel pump control module
- Wiring or connector issues in the fuel pump control circuit
- Failed fuel pump relay
- Defective fuel pump
02. Symptoms You Will Notice
- Engine cranks but does not start
- Loss of power or hesitation during acceleration
- Check Engine Light illuminated
- Poor fuel economy
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to verify the code and check for additional codes.
Step 2: Inspect the fuel pump control circuit wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test the fuel pump relay and fuel pump control module for proper operation.
Step 4: Check fuel pressure with a gauge to confirm the pump is delivering adequate pressure.
Step 5: If all else is fine, replace the fuel pump control module or fuel pump as needed.
