Description
Is a scooter throwing Error Code 52, struggling with cold starts, or suffering from a "missing beat"?

Why Mechanics Choose This Replacement Sensor (Key Features):
- Direct Activa 6G Fitment: 100% compatible with BS6 Honda Activa 6G models.
- Solves Starting Issues: Instantly eliminates engine misfires, erratic idling, and sudden stalling.
- True Plug-and-Play: Features the exact OEM-style coupler for a hassle-free, wire-cut-free installation.
- Cost-Effective Repair: Hall Sensor only—save your customers money by not replacing the entire expensive stator coil assembly.
- Heavy-Duty Build: Heat-resistant and vibration-proof to survive harsh internal engine temperatures.
Note: This is the high-quality replacement Sensor Only. You do not need to replace the entire stator/magnet coil assembly if only your sensor has failed.
Frequently Asked Questions
What are the signs of a faulty Activa 6G hall sensor / magnet coil?
Common symptoms include hard starting (even with full battery), engine misfires, rough idling, sudden stalling at low RPM, or reduced pickup power. If the bike cranks but doesn't fire, this sensor is often the culprit in BS6 Activa 6G models.
Is this hall sensor plug-and-play for Activa 6G?
Yes — black socket variant matches OEM fitment perfectly. No wiring changes needed; just unplug old, plug new, and secure. Takes 15–30 minutes for most mechanics.
Compatible: Honda Activa 6G BS6 (2020+ models). Not for pre-BS6 or other brands without checking connector.
Do I need any special tools to replace it?
Basic toolkit (screwdrivers, socket set) is enough. For diagnosis first, use our Universal BS6 Fuel Pump Tester to rule out fuel issues before replacing the sensor.
How to Replace: Step-by-Step Guide
- Park bike safely, turn off ignition, disconnect battery negative terminal.
- Remove left side cover / access flywheel area (near crankshaft).
- Locate magnet coil / hall sensor (small black component with 3–4 wire connector).
- Unplug connector carefully, unscrew/remove faulty sensor (1–2 screws).
- Install new MecSpot black socket hall sensor — align, secure screws, plug connector.
- Reconnect battery, reassemble cover, start engine — check for smooth idle & no warning lights.
Pro tip: Clean area around sensor before install to avoid dust issues. For full troubleshooting: Activa 6G Hall Sensor Replacement Guide →
