C0659Right Front Wheel Speed Sensor B Range/Performance
- Generic OBD-II code · Chassis
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- The second right front speed signal arrives, but its quality or value does not fit. For sensors using the VDA AK protocol, Infineon's TLE5046SiC shows what a module can read besides speed: a 3-bit air gap gauge and, in one variant, a reserve bit that is set once the magnetic signal drops below twice the value at the limit air gap. A weakening signal thus becomes visible before pulses are lost. UN Regulation 13-H requires ABS sensor anomalies that cannot be seen at standstill to be detected by 10 km/h, or by 15 km/h where a wheel that is not turning could cause a false alarm; how quickly a B channel gets rated remains unpublished, and no carmaker documents C0659. Likely causes: too large an air gap from bearing play or a loose holder, a dirty or damaged encoder, a wrong sensor.
