What is P0262?

The diagnostic trouble code (DTC) P0262 indicates a problem with the fuel injector circuit, specifically for cylinder 2. When your vehicle’s Engine Control Module (ECM) detects that the fuel injector circuit for this specific cylinder is operating at a low voltage or is shorted to ground, it triggers this code. This issue can lead to poor engine performance, increased emissions, and even engine misfires. If you own a vehicle like the 2005-2010 Ford F-250, this code is often associated with poor fuel delivery to the engine, which can result in significant performance drops. Drivers may notice their vehicle hesitating during acceleration, reduced fuel efficiency, or stalling. Ignoring this code can lead to further damage to the engine or emissions system, potentially resulting in costly repairs. It’s essential to address P0262 promptly to maintain your vehicle’s performance and reliability.

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

Symptoms

Common symptoms when P0262 is present:

  • Check engine light stays on constantly, indicating an ongoing issue with the fuel injector circuit.
  • Engine hesitates during acceleration, making it difficult for the driver to maintain speed.
  • Fuel economy decreased by 10-15%, resulting in more frequent trips to the gas station.
  • Rough idling, where the engine shakes or vibrates while at a standstill.
  • Engine misfires, leading to a noticeable loss of power and potential stalling.

Possible Causes

Most common causes of P0262 (ordered by frequency):

  1. Faulty fuel injector - Most common cause (60% likelihood). A defective fuel injector can lead to inconsistent fuel delivery.
  2. Wiring issues - (20% likelihood). Damaged or corroded wires may cause a poor connection, affecting the injector's performance.
  3. ECM malfunction - (10% likelihood). A faulty engine control module can misinterpret the signals from the fuel injector.
  4. Fuel delivery problems - (5% likelihood). Blockages in the fuel line can restrict flow to the injector.
  5. Grounding issues - (5% likelihood). Poor grounding connections can affect the circuit's performance.
