As some of the most advanced two-stroke engines ever built, the E-TEC series features a sophisticated Engine Management Module that monitors every internal component. Because these engines lack a traditional carburetor, understanding the ECU's telemetry is essential for diagnosing issues like "Limp Mode" (S.A.F.E.) or no-start conditions. This guide provides the definitive lookup table for E-TEC specs and explains those flashing EMM lights.
How Do I Check Fault Codes on an Evinrude E-TEC?
There are three primary ways to identify issues on an E-TEC engine:
- The EMM LEDs: Located on the Engine Management Module, four colored LEDs provide a hardware-level status report during cranking and operation.
- SystemCheck Gauges: Four lights on the dashboard (HOT, NO OIL, CHECK ENGINE, LOW OIL) indicate general system failures.
- EV-Diagnostics Software: By connecting a USB-to-Serial cable to the diagnostic port, you can read the exact code number and fault hour.
What Do the Lights on My Evinrude E-TEC EMM Mean?
The EMM LEDs are the most powerful "free" diagnostic tool for E-TEC owners. Their meaning changes depending on the engine's state:
| LED | Engine Cranking | Engine Running |
|---|---|---|
| LED 1 | Stator producing >30V | ON: Charging system fault |
| LED 2 | EMM sees Crank Position | ON: Injector or Ignition fault |
| LED 3 | 5V Sensors providing data | ON: Sensor circuit fault |
| LED 4 | Engine NOT grounded (Stop) | ON: Overheat or Oil fault |
Common Evinrude E-TEC Fault Codes List
If you are using diagnostic software, these are the most frequently encountered fault codes:
- Code 11 (TPS Out of Range): The Throttle Position Sensor is reporting incorrect voltage. Often caused by a loose throttle cable.
- Code 16 (CPS Intermittent Sync): The engine is losing track of the piston position. Check the CPS sensor for debris.
- Code 25 (EMM Overheat): The EMM itself is too hot. Check the cooling water line that runs through the module.
- Code 38 (Oil Pressure Low): The EMM has commanded oil, but the sensor hasn't detected it. This triggers S.A.F.E. Mode.

How to Reset Evinrude E-TEC Codes
Most E-TEC codes are "Stored Faults," meaning they remain in memory after the problem is fixed. These must be cleared using the "Clear Stored Faults" button in the EV-Diagnostics software. However, "Active Faults" (like an overheat) will clear themselves from the dashboard gauge once the condition is resolved and the power is cycled.
