CKP Sensor 39180-22600/39180-03000/9660930408

• Engine won’t start or stalls unexpectedly—especially noticeable when the engine is hot.
• “Check Engine” light illuminates, often accompanied by codes like P0335 (CKP Sensor A Circuit Malfunction).
• Rough idling, frequent misfires, or hesitant acceleration.
• Poor fuel economy or reduced power.

Nope. Hyundai CKP sensors—especially OEM ones—do not require any relearning or calibration after installation

1. Inspect the sensor and wiring—look for physical damage, corrosion, or wiring issues (common culprits)

2. Check resistance using a multimeter:

• Disconnect the sensor
• Measure resistance between the pins; compare with manufacturer specs (typically 200–1,000 ohms)

3. Probe voltage output with a voltmeter—voltage should fluctuate with engine RPM; flat-line readings suggest sensor failure

Some temporary fixes include tightening the connector, cleaning it, or testing wiring continuity, though ultimately a replacement is likely needed.
