Causes

Faulty yaw rate sensor (internal failure)
Damaged or corroded sensor connector or wiring harness
Poor ground or battery supply to sensor/module
Intermittent CAN or sensor signal bus fault
Incorrect sensor orientation, loose mounting or mechanical damage
Faulty ABS/ESC control module or software/calibration fault

Symptoms

ABS/ESC/stability control warning lamp illuminated
Traction control or stability functions disabled
Vehicle feels less stable during cornering or slippery conditions
Diagnostic trouble codes stored in ABS/ESC module
Possible drivability complaints if stability system actively intervenes

What to check

Read ABS/ESC module fault memory and freeze frame data
Check for other related codes (CAN bus, wheel speed, steering angle)
Visually inspect yaw sensor and mounting for damage or looseness
Inspect connector for corrosion, bent pins, water ingress or contamination
Check wiring harness continuity, short to ground and short to Vbatt
Verify vehicle battery and charging system voltage

Signal parameters

Typical sensor supply: ~5 V (verify vehicle specification) and good ground
Common analog output: approx. center voltage ~2.5 V with ± swing (0.5–4.5 V) proportional to yaw rate (vehicle-specific)
Some sensors provide digital (CAN or SENT) messages instead of analog — expect valid CAN frames from ESC/IMU module
Output should change smoothly with manual rotation of vehicle body (when safe) or when rotated on hoist — no dropout or erratic spikes
Sensor self-test/diagnostic flags in ABS/ESC module should be clear

Diagnostic algorithm

Connect scan tool; record C2006 occurrence count, freeze frame and related codes. Note when code set (ignition on, driving, etc.).
Visually inspect yaw sensor and harness; repair any physical damage, corrosion, or loose mounting. Replace weather seals if compromised.
With ignition ON (engine off) verify sensor supply voltage and ground at connector pins per vehicle wiring diagram. Do not short pins.
Backprobe sensor output while gently rotating vehicle body or steering (follow safety procedures) or use a lab scope to observe signal. Look for steady centered voltage and smooth change without dropout, spikes or noise.
If sensor uses CAN/SENT, monitor data frames with diagnostic tool and confirm yaw rate values change logically with vehicle movement. Check CAN continuity and termination.
Check continuity and resistance to ground for wiring; repair any open/shorts. Wiggle-test harness to reproduce intermittent faults.
Verify ABS/ESC module power and ground; check fuses/relays feeding sensor circuit and module.
If wiring and supplies are good but signal remains implausible, swap with known-good sensor (if available) or install replacement sensor and retest.
After repair, clear codes and perform sensor/module relearn or calibration procedure required by manufacturer. Road-test to confirm no reoccurrence.
If replacement sensor does not clear fault, consider ABS/ESC module fault and perform module diagnostics or reflash per dealer procedures.

Likely causes

Water ingress/corrosion at sensor connector causing intermittent signal
Wire chafing or pinched harness near steering column or ABS module
Sensor failed due to impact or age
Blown fuse or low battery voltage affecting sensor supply
Module firmware bug or previous failed calibration after service

Fault status

⚠️ Status

Yaw Rate Sensor Signal Fault detected by ABS/ESC. Sensor output missing, implausible or intermittent. Stability control functions may be disabled until fault is resolved.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0 - 3.0 hours
