Crankshaft and Camshaft Position Sensor Failures on Geely Engines: Symptoms, Diagnosis, and Replacement
For Geely owners and repair shops, a failing Geely crankshaft sensor or Geely camshaft sensorcan cause hard starts, stalls, and power loss. As a supplier with full supply chain management, SC-industry provides genuine Geely parts. This guide covers symptoms, diagnosis, and replacement to help you reduce comebacks and keep customers satisfied.
What these sensors do
The crankshaft sensor provides precise crankshaft angle and speed signals. The camshaft sensor identifies cylinder 1 TDC and intake/exhaust strokes. Together they determine injection timing and ignition timing. Without them, the ECU cannot run the engine correctly. A crankshaft camshaft sensor failure stops the engine from starting or running smoothly.
Common symptoms
Geely crankshaft sensor failure: The most common sign is no start after hot soak. Other signs include intermittent stall and a dead tachometer. The engine may crank but not fire.
Geely camshaft sensor failure: You will see longer crank time, rough idle, and weak acceleration. These symptoms often trigger P0335 or P0340 codes.
Simple diagnosis
Use a multimeter to check resistance or voltage output. Use an oscilloscope or scan tool to view waveform cleanliness. Check harness and connectors for corrosion or looseness. A clean square wave indicates a good hall effect crankshaft sensor. A missing or distorted signal points to failure. For the camshaft sensor, verify the signal switches as the cam turns.
Replacement is usually easy
Both sensors are typically easy to remove and install. Many shops choose replacement over testing. SC-industry supplies hall effect crankshaft sensor and camshaft sensor that have been waveform tested piece by piece. This means you can replace with confidence. Our Geely crankshaft sensor and Geely camshaft sensor come with original matching plugs. A crankshaft camshaft sensor failure does not have to become a repeat repair.
