What does code P26E2 mean?

Q: What does code P26E2 mean?

Fuel Mode Indicator Lamp Control Circuit Low. P26E2 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the fuel mode indicator lamp. This lamp is used on some vehicles to inform the driver of the current fuel mode, such as when the engine is operating in a special economy or performance calibration. The PCM monitors the circuit and sets this code when the voltage on the control wire is lower than expected, typically indicating a short to ground or an open circuit.
