The camshaft position sensor tracks camshaft rotation and reports it to the engine computer, helping coordinate valve timing with fuel and spark. When it fails, drivers often notice rough idling, poor acceleration, or an illuminated check engine light.

This sensor fits the Honda Civic and Crosstour lineup using the common K-series/L-series engines shared across Civic, Accord, and CR-V models, matching OE part number 37510-R40-A01.

Built to the original specification, it's an affordable, confidence-inspiring swap for a worn or failing sensor.
