ComAp controllers show this as a text alarm on the display, not as a numbered code.
The ComAp controller has lost the engine speed signal during operation. This can cause engine shutdown as the controller cannot determine if the engine is running or at correct speed.

ComAp controllers accept both magnetic pickup (MPU) and digital sensors. The input type is configured in InteliConfig. MPU sensors generate AC voltage proportional to speed.
Measure resistance (typically 100-1000 ohms). Spin a metal object past the sensor and measure AC voltage output. Check gap to tone ring is per specification (usually 0.5-2mm).
Send us the code or alarm and what the generator is doing, and one of our engineers will help you diagnose it.

A fault code names a symptom, not a cause. Our engineers have written the diagnostic sequence they use on site for this class of fault — ranked causes, ordered steps with the reading expected at each one, and the point at which to stop and call someone.
