C065BRight Front Wheel Speed Sensor B Circuit High
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- In C065B the line of sensor B at the right front shows a level above its allowed window, which mostly means a short to the supply. TI's TPIC7218-Q1 sets this limit by sensor type: for active two-level sensors any current over 20 mA counts as overcurrent, for three-level VDA sensors only above 40 mA, in both cases marked as a possible short to battery. A separate flag reports a short to battery while the channel is switched off, and the supply switch caps current at 50 to 150 mA when the line is shorted to ground. Infineon's TLE5046SiC explains the wide band: its speed pulse alone may draw up to about 32 mA. Inspect the harness near hot or moving parts and for contact with another channel, then test the sensor. No carmaker documents C065B.
