Causes
- Damaged or corroded connector or wiring to the steering sensor
- Poor or lost sensor ground or reference voltage
- Failed steering angle/position sensor or internal electronics
- Faulty clock spring/spiral cable in the steering column
- Control module communication error or software fault
- Sensor not calibrated / out of range after repairs or battery disconnect
Symptoms
- Warning lamp(s) illuminated (EPS, ABS, VSC/ESC, or general fault lamp)
- Steering assist abnormal or reduced (intermittent power steering assist loss)
- Stability control or traction control disabled or behaving erratically
- Steering angle reading incorrect or not changing on scan tool
- Vehicle may require steering angle sensor relearn or alignment to restore systems
What to check
- Read freeze frame and full list of stored DTCs with a capable scan tool (check ABS/EPS modules too)
- Inspect steering column area, sensor connector, and clock spring for damage or loose connectors
- Check fuses and power/ground circuits related to the steering/ABS/EPS modules
- With ignition ON, backprobe sensor connector to confirm reference voltage (~5 V) and ground present
- Use a diagnostic tool to read live steering angle/position values while turning the wheel and compare with expected center value
- Check for corrosion, water ingress, or bent pins at connectors
Signal parameters
- Reference voltage: typically ~5.0 V (acceptable ~4.5–5.5 V) on power/reference pin
- Sensor signal voltage center/zero point: roughly ~2.5 V at straight ahead for many sensors (acceptable ~0.5–4.5 V depending on design)
- Signal should vary smoothly and proportionally with steering angle when turning the wheel
- Some sensors output digital/CAN values or counts — expect a steady increment/decrement with wheel rotation (commonly tens to thousands of counts across full lock)
- Noisy, jumping, or frozen values indicate wiring, sensor, or communication faults
Diagnostic algorithm
- Confirm DTC and note conditions (ignition on, vehicle moving, steering position) using a scan tool
- Visually inspect sensor, wiring harness, and connectors for damage, corrosion, or pin issues
- Check fuse(s) for related systems (EPS/ABS) and power/ground at sensor connector with meter
- Backprobe and measure reference voltage, ground continuity, and signal while slowly rotating the steering wheel; observe live data on scan tool for smooth change
- If signal reference or ground is missing or erratic, trace and repair wiring/connector faults (repair, secure, clean contacts)
- If wiring and power/ground are good but signal is out of range or non-linear, replace or bench-test the steering angle sensor per service manual
- If sensor replacement performed or battery disconnected, perform required steering angle sensor calibration/relearn procedure with manufacturer scan tool
- Clear codes, perform test drive and recheck for reappearance of P1716 and related codes
- If communication errors persist, inspect ABS/EPS module connectors and CAN bus for faults and test module operation; consult wiring diagrams and manufacturer procedures as needed
Likely causes
- Open or short in signal, reference (5V) or ground circuit
- Connector pins pushed out, bent, corroded or contaminated
- Worn/damaged clock spring interrupting signal to column-mounted sensor
- Failed steering angle sensor (Hall-effect or potentiometer)
- Calibration/zero-point mismatch between sensor and ECU after service
Fault status
Status
Steering sensor circuit/communication fault detected — signal out of range, intermittent, or missing. May disable EPS/ABS/stability functions until repaired/calibrated.
Repair difficulty: Medium
Diagnostic time: 0.5-3.0 hours
