BAIC Huansu S5 1.3T / Bisu T3 1.5T Ignition Coil 37050100A03B00

When your Honda or Acura experiences hard start, engine shake, weak acceleration, or stalling, and the dash shows a check engine light, this usually indicates a worn or failed crankshaft position sensor. This sensor monitors crank speed and position and sends signals to the ECU to precisely control ignition timing and injector quantity; a critical engine component. OEM number 37510-RNA-A01; compatible with Honda Accord, Civic, CR-V, and Acura TL, RDX, and other mainstream models. During installation, disconnect the battery negative terminal and ensure the sensor clearance with the flywheel ring gear meets factory standards to avoid signal anomalies from improper installation.
