C065ERight Front Wheel Speed Sensor B Incorrect Component Installed
- Generic OBD-II code · Chassis
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- C065E means the module rejects the part fitted as the second speed sensor on the right front hub. Wheel speed sensors differ in their output scheme, and the receiving electronics are set up for one of them: TI's TPIC7218-Q1 is configured per sensor type, using two current thresholds for active sensors and four for VDA sensors that add 9 data bits. Allegro's A81415, a power management chip for electromechanical brakes, decodes two-level, PWM and three-level AK sensors, high-resolution versions included. Even within one family, Infineon sells the TLE5046SiC as an LR and an ERR variant in which bit 0 means air gap reserve in one case and an error flag in the other. Compare part numbers before suspecting the wiring; no carmaker documents C065E.
