Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Structure and inner electrical connection
The measuring procedure is based on Hall IC. The output signal uses a flank to show Low status and a gap to show High status. The intake camshaft sensor operates on the same principle as the crankshaft sensor. However, the camshaft sensor wheel differs fundamentally. A special mark pattern enables emergency operation in the event of failure of the crankshaft sensor. However, the resolution of the camshaft sensor signal is too imprecise to replace the crankshaft sensor during normal operation.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
