Frequently Asked Questions
- What is a reluctor ring?
- The reluctor ring (tone wheel) is a toothed ring on the crankshaft. The sensor reads the teeth passing by to determine crank position and speed.
- Can metal debris cause P0336?
- Yes — magnetic sensors attract metal shavings from normal engine wear. Cleaning the sensor tip sometimes resolves P0336.
