P2292 Injector Control Pressure Erratic

P2292 describes an injector control pressure that jumps around instead of sitting steadily below or above target. No manufacturer documents its detection logic publicly: Ford's 2014 PCM code table lists the code without a MIL marking, and the 6.0 L Power Stroke summaries only describe the steady checks P2284, P2288 and P2290. On a HEUI engine an unsettled pressure can come from air in the oil, an injection pressure regulator that sticks and releases, a failing high-pressure oil pump or a loose sensor connection. CARB requires diesel fuel pressure control, explicitly including hydraulic fluid, to be monitored. Drivers notice surging, stumbling or intermittent power loss. A pure dropout of the sensor signal fits P2287 better.

Likely causes

Symptoms

• Surging or bucking under steady throttle
• Intermittent power loss
• Rough idle

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
