Causes
- Open, shorted or damaged wiring between the sensor and control module (CAN/LIN or analog lines).
- Poor or corroded connector contacts at the sensor or control module.
- Failed steering wheel angle sensor (internal electronics or connector).
- Faulty ABS/ESP or gateway module that reads the sensor data.
- CAN/LIN bus fault (missing terminator, short to battery/ground, high bus error rate).
- Blown fuse or lost power/ground to the sensor or related module.
Symptoms
- ESP/ABS/traction control warning lights illuminated.
- Steering angle or stability-related messages on the instrument cluster.
- Loss or malfunction of stability control, traction control or adaptive cruise related features.
- Cruise control may be disabled or behave erratically.
- Steering angle reading on diagnostic tool is missing, fixed at zero or erratic.
- Possible steering calibration or alignment warnings; some driver aids unavailable.
What to check
- Scan vehicle with an OBD-II / manufacturer diagnostic tool. Read U1305 and any related codes or bus errors.
- Check for other module communication codes (U0121, U0155, etc.) to identify a bus-wide problem.
- Visually inspect sensor connector and wiring at the steering column for damage, corrosion, pin push-out.
- Verify sensor power and ground at the connector with key on (see signal parameters).
- Measure CAN/LIN bus voltages at the sensor connector and at nearby modules; check for correct idle voltages and termination.
- Perform continuity checks from sensor connector pins back to the relevant control module(s) with ignition off.
Signal parameters
- Power supply: typically 5 V reference (±0.5 V) or fused ignition supply — confirm with manufacturer wiring diagram.
- Ground: good chassis ground continuity and
- Analog sensor types: two sinusoidal outputs (sine/cosine) that vary approx. 0.5–4.5 V across wheel travel (exact values vary by model).
- Digital/CAN type: no direct analog output — data appears on CAN bus. Idle CAN voltages typically ~2.5 V; dominant bits pull CAN_H toward ~3.5 V and CAN_L toward ~1.5 V.
- LIN bus (if used): idle ~12 V or defined LIN levels depending on network — check manufacturer spec.
- Resistance: internal sensor winding/resistance varies by design; use service data for exact Ohms before replacement.
Diagnostic algorithm
- Record all DTCs and freeze frame data with a capable scan tool. Note conditions (ignition state, wheel position).
- Attempt to read live steering angle sensor data. If no data, confirm the sensor is present in the network map.
- Inspect connector and wiring at the steering column for physical damage, corrosion or loose pins. Repair any visible faults.
- With ignition on, measure sensor supply voltage and ground at the sensor connector. Compare to manufacturer spec.
- If analog sensor: probe signal lines while slowly turning the steering wheel and observe voltage change. If digital: monitor CAN frames and error counters for the sensor node.
- Check CAN/LIN bus integrity: measure CAN_H and CAN_L voltages at multiple points, check for proper termination and for any short to battery/ground.
- Perform continuity/resistance checks from sensor pins to the related control module connector. Repair wiring faults found.
- If wiring and power/ground are good but no communication, swap/replace the steering angle sensor with a known-good unit (or use an appropriate bench test) and test.
- If new sensor or wiring repaired, perform manufacturer-required sensor calibration/relearn and clear codes. Re-test vehicle functions.
- If problem persists and network issues remain, consider diagnosing or replacing the gateway/ABS/ESP module per service procedures and consult manufacturer technical bulletins.
Likely causes
- Corroded or loose sensor connector or wiring at the steering column.
- Broken wiring harness (pinched at column, under-dash, or during steering work).
- Failed steering wheel angle sensor.
- CAN bus wiring fault or high bus error rate preventing data frames.
- Faulty control module (less common) or missing module wake-up.
Fault status
Status
