P2267 reports that the signal of water-in-fuel sensor A sits above its valid range, which usually indicates an open signal or ground path, a disconnected sensor or a short to a voltage source. Stellantis has a case file for 2025 and 2026 Ram 2500 to 5500 trucks with the Cummins 6.7L: after the fuel filter module has been drained, the warning lamp may stay on with P2267 and P2269. Instead of replacing parts, technicians drain both filter stages, remove the sensor, wipe residue off its probes, refit it at 3 Nm and prime the system with the lift pump. That points to the sensor reacting to leftover contamination as well as to wiring. P2266 is the low-side counterpart, P2268 the intermittent version.

Likely causes

Residual contamination on the probes after draining the filter
Unplugged sensor or open signal or ground wire
Signal wire shorted to a supply voltage
Defective water-in-fuel sensor

Symptoms

  • Water-in-fuel lamp stays on after draining
  • Often appears together with P2269
