DTC P1292 refers to a diagnostic trouble code that indicates the fuel pulse is within range but is higher than expected. This code is typically associated with the fuel delivery system and can suggest that the engine control module (ECM) is detecting an anomaly in the fuel injection process. The ECM monitors various parameters to ensure optimal engine performance, and when it identifies that the fuel pulse duration is longer than anticipated, it triggers this code.

Common symptoms associated with DTC P1292 may include:

• Reduced engine performance
• Increased fuel consumption
• Rough idling or stalling
• Check Engine Light illuminated
• Difficulty starting the engine
