If you are seeing "0802" flashing on your Jungheinrich’s display panel, your truck may experience reduced performance, a complete drive lockout, or intermittent shutdowns. This article provides a deep dive into what error code 0802 means, its root causes, step-by-step diagnostic procedures, and practical solutions to get your forklift back in operation. Error Code 0802 is a traction-related fault. Specifically, it indicates a “Drive Motor Temperature Sensor – Plausibility Error” or, in some technical manuals, a “Communication Interruption with Drive Controller (Temperature Channel).”

By following the resistance measurements, visual checks, and step-by-step repair advice in this article, you can solve error 0802 quickly, minimize downtime, and avoid unnecessary service bills. Always prioritize safety and refer to your model’s specific wiring diagram. If you’re unsure at any step, a Jungheinrich technician is your best ally.

One of the more common and often misunderstood fault codes encountered across various Jungheinrich models—including the ETV, EFG, and EKS series—is .

A: Indirectly, yes. A very low battery can cause voltage drops that make the sensor’s signal unstable, triggering a plausibility error. Always charge your battery fully before diagnosing.

A: Temporarily, maybe. But without fixing the root cause (sensor/wiring/controller), the error will return, usually within minutes of operation.

A: That points directly to an electrical fault (broken wire, bad connector, or dead sensor) rather than a real temperature problem. Follow the measurement steps above. Conclusion Jungheinrich error code 0802 may seem intimidating, but it is a well-understood fault with a logical diagnostic path. In the vast majority of cases, the issue is a failed temperature sensor (KTY) or a damaged wire in the harness between the drive motor and the controller. Expensive replacements like the drive controller are possible but rare.

A: No. Error 0801 typically indicates a short circuit of the temperature sensor (permanent low resistance). Error 0802 is a plausibility or range error (signal missing or out of bounds).
