To diagnose P062B, use the GeekOBD APP to scan for codes and view freeze frame data. Check the fuel pump control module and wiring for any visible issues. Follow the app's diagnostic steps for a thorough check.

What vehicles are most commonly affected by P062B?

P062B frequently affects vehicles such as the 2015-2019 Ford F-150, Chevrolet Silverado 1500, and GMC Sierra 1500. Always check for recalls or technical service bulletins (TSBs) related to this code.

How can I prevent P062B from happening again?

Regular maintenance, including checking electrical connections and ensuring fuel system components are in good condition, can help prevent the P062B code from recurring.

What is P062B?

The P062B diagnostic trouble code (DTC) indicates an issue with the fuel pump control module's performance. This code is typically triggered when the powertrain control module (PCM) detects that the fuel pump control module is not operating as intended, which can lead to insufficient fuel delivery or pressure. In practical terms, this means your vehicle may experience issues like poor fuel economy, difficulty starting, or even stalling while driving. The code commonly affects vehicles from manufacturers like Ford, Chevrolet, and GMC, especially models produced between 2015 and 2019. The fuel pump control module is crucial for regulating fuel pressure and flow to the engine; if it fails, it can cause serious performance issues. Ignoring this code can lead to further complications, such as engine misfires or long-term damage. Consequently, addressing the P062B code promptly is not only wise but necessary for maintaining optimal vehicle performance.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P062B is present:

  • Check engine light stays on constantly, indicating a persistent issue with the fuel system.
  • Engine hesitates during acceleration, which can cause a dangerous situation if it occurs while merging onto highways.
  • Fuel economy decreased by 10-15%, leading to more frequent trips to the gas station and increased fuel expenses.
  • Difficulty starting the engine, especially after prolonged periods of inactivity, suggesting that the fuel pump might not be delivering fuel efficiently.
  • Unusual whining noises from the fuel tank area, which might indicate that the fuel pump is struggling to operate.

Possible Causes

Most common causes of P062B (ordered by frequency):

  1. Faulty fuel pump control module (40% likelihood) - This is the most common issue, often due to electrical failures or component wear.
  2. Wiring issues (30% likelihood) - Damaged or corroded wiring can interrupt power to the fuel pump control module, leading to performance problems.
  3. Fuel pump failure (20% likelihood) - A malfunctioning fuel pump can also trigger the P062B code, often requiring replacement.
  4. Software issues (5% likelihood) - Occasionally, a software glitch in the PCM can lead to erroneous fault codes.
  5. Connector issues (5% likelihood) - Loose or corroded connectors can disrupt the signal between the PCM and the fuel pump control module.
