Causes

Damaged or corroded sensor connector or wiring harness
Open, short or high-resistance in sensor signal/ground circuits
Poor or missing ground at sensor or ABS/ESC control module
Faulty lateral acceleration sensor (internal failure)
Contaminated or water-damaged sensor
Faulty ABS/ESC control module or internal module software fault

Symptoms

ABS, ESC or Traction Control warning lamp illuminated
Loss or reduction of stability/traction-control intervention
Stored fault codes related to lateral accel/yaw/IMU sensors
Possible degraded braking or stability behavior during cornering
No obvious symptom other than warning lamp and logged code

What to check

Retrieve full code list and freeze frame data with a diagnostic scanner
Check for other related codes (yaw rate, longitudinal accel, CAN bus)
Visually inspect sensor and harness for damage, corrosion, moisture
Check connector pins for bent, pushed out or shorted terminals
Measure sensor supply, ground and signal voltages with key ON, engine OFF
Backprobing or resistance check of wiring to module to verify continuity

Signal parameters

Typical sensor zero output at rest: approximately mid-supply (≈2.5 V on 5 V systems) — confirms zero-g bias
Signal swing: roughly ± (0.5–2.0) V around zero bias depending on sensor sensitivity
Supply voltage: 5 V reference (verify 5 V present at sensor supply pin)
Ground: near 0 V with low resistance to chassis ground
Communication: some modules send sensor data over CAN/SWC — verify messages if applicable

Diagnostic algorithm

Connect scan tool, note C0061 and any related codes, record freeze frame and live lateral accel data.
Visually inspect sensor, bracket, and harness for damage, water intrusion, or loose mounting. Repair or secure as needed.
With connector disconnected, inspect pins for corrosion, bent pins or contamination. Clean or replace connector if needed.
With wiring harness connected, backprobe sensor power, ground and signal. Verify ~5 V reference, good ground (
Wiggle test harness while monitoring live data to check for intermittent opens/shorts. Repair wiring if values fluctuate or drop out.
Perform resistance/continuity checks from sensor pins to ABS/ESC module pins to confirm no open circuits or unexpected shorts to chassis.
If electrical checks ok but signal is out of expected range or inconsistent, replace the lateral acceleration sensor per OEM procedure.
After replacement, clear codes and perform required sensor/module initialization/calibration following manufacturer instructions.
If problem persists after sensor replacement, inspect/replace ABS/ESC control module or investigate CAN bus/communication faults with specialized diagnostics.

Likely causes

Connector corrosion or bent pins at lateral acceleration sensor
Broken/abraded wiring between sensor and ABS/ESC module
Poor ground connection at sensor or chassis ground point
Failed lateral acceleration sensor
Intermittent module communication or power supply issue
