Yaw Rate Sensor Circuit Fault
AI status
Completed
Completed
100%
Causes
- Faulty yaw rate (yaw rate/rotation) sensor
- Open, short or intermittent wiring in sensor harness
- Corroded, loose or contaminated connector/terminal
- Bad sensor ground or missing reference/supply voltage (fuse, power rail)
- Water ingress or physical damage to sensor
- Sensor incorrectly mounted or misoriented after service
Symptoms
- ABS, ESC or Traction Control warning lamp illuminated
- Stability control and traction assist disabled (loss of ESC functionality)
- Possible drivability or braking system warnings (depending on vehicle)
- Diagnostic trouble code present for yaw rate sensor circuit
- Intermittent or persistent fault; may return after wet conditions or jostling harness
What to check
- Connect a manufacturer-level scan tool; read DTCs and freeze-frame data
- Monitor live data: yaw rate output, steering angle, wheel speeds and vehicle speed; note values at rest and while turning
- Check for related codes (ABS, steering angle sensor, wheel speed sensors)
- Visually inspect sensor mounting and electrical connector for corrosion, damage or water intrusion
- Check fuse(s) and supply voltage to the sensor circuit with key ON
- Back-probe sensor connector: verify reference voltage (typically 3.3–5 V), ground continuity and sensor output
Signal parameters
- Typical supply voltage: usually 3.3 V or 5 V reference (vehicle-specific)
- Typical idle/rest output: approx. mid-supply (e.g., ~2.5 V on 5 V systems) representing ~0 deg/s
- Output changes proportionally with yaw rate (positive/negative deflection as vehicle rotates)
- Update rate: sensor should update continuously (tens of Hz; exact rate vehicle-specific)
- No large spikes, dropouts or steady out-of-range voltage when vehicle is moved/steered
Diagnostic algorithm
- Connect scan tool, record C2364 and any related codes; record freeze-frame and live yaw rate vs steering angle/wheel speed at rest and during low-speed turns.
- Visually inspect yaw sensor and connector for damage, corrosion, or water intrusion. Repair/clean if found.
- With ignition ON (engine off), probe connector: verify sensor supply voltage and good ground. Compare to vehicle specification. Replace blown fuse or restore power/ground if absent.
- Back-probe sensor output with multimeter or scope at rest — expect mid-supply bias. Rotate steering/wheel (vehicle secured) or gently rotate vehicle body on lift and observe output change. No change or out-of-range reading indicates sensor or wiring fault.
- Perform continuity/resistance checks between sensor connector and control module for open/shorts, inspect harness through steering/suspension range of motion.
- If wiring and connectors test good but signal is implausible, replace the yaw rate sensor. After replacement, perform required calibration/initialization via scan tool.
- Clear codes and road-test or perform required self-tests. If code returns, consider control module fault and proceed to module-level diagnostics per manufacturer guidance.
Likely causes
- Damaged wiring at suspension/steering joint from movement
- Corroded connector allowing intermittent contact (moisture/road salt)
- Sensor failed electrically (internal MEMS failure)
- Blown fuse or lost +V/ground to sensor
- Sensor knocked out of position during service (wrong orientation)
Fault status
Status
Yaw Rate Sensor Circuit Fault — stability control module detects missing, implausible or out-of-range yaw rate signal; ESC/ABS functions may be disabled.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
