## ⚙️ Key Features

-   0.057 kg
-   28 applications across D, TAMD and MD series engines
-   Instruments group
-   Rated 74 A

## 🔌 Function

Reads the passing flywheel or gear teeth and sends the pulse train that the tachometer and control system use as engine speed.

## ⚠️ Common Signs of Failure

-   Tachometer reading zero, erratic or wildly high
-   Engine cutting out or refusing to start with no fuel fault
-   Rev limiter or governor behaving unpredictably
-   Sensor tip clogged with steel debris off the flywheel
-   Corrosion in the sensor plug, or a chafed lead

## 🛠️ Service Notes

-   Check the air gap and clean the sensor tip before condemning it - a fuzz of steel filings on the tip is a common and cheap fix
-   Inspect the flywheel or gear teeth for damage at the same time; a chipped tooth gives the same erratic reading
