POLARIS RZR 1000 EPS Power Steering Heavy

Vehicle Speed Sensor (Hall Effect)

The EPS controller requires accurate speed data to modulate steering assistance levels. A faulty speed sensor often triggers a 'limp mode' or failsafe that disables power assist entirely to prevent erratic steering at high speeds, resulting in a heavy manual steering feel.

Voltage Regulator / Rectifier

The EPS motor is the most power-intensive component on the RZR; if the voltage regulator output exceeds ~15.5V or drops significantly, the EPS module will automatically shut down to prevent damage to its internal capacitors and logic board.

Steering Rack and Pinion Assembly

If the EPS motor is receiving correct power and speed data, the 'heavy' sensation is likely mechanical binding. The factory rack is prone to internal gear wear or shaft bending, which creates high physical resistance that the power assist cannot overcome.
