C1141 – Wheel Speed Sensor LF Tone Ring Tooth Missing Fault: Symptoms, Causes, Diagnosis & Repair Cost (2026 Guide)

C1141

Last updated:

Overview

The control module stored C1141 because it detected a problem with: Wheel Speed Sensor LF Tone Ring Tooth Missing Fault.

C1141 relates to Wheel Speed Sensor LF Tone Ring Tooth Missing Fault. Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.

What does the C1141 code mean?

When C1141 is set, the vehicle’s diagnostics detected an issue described as: Wheel Speed Sensor LF Tone Ring Tooth Missing Fault. In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.

Common symptoms of C1141

  • Unusual brake feel
  • Speed sensor related warnings
  • Stability intervention changes
  • Noise during braking
  • ABS/traction/stability warning
  • Pedal feedback changes

Possible causes

  • Fault affecting Wheel Speed Sensor LF Tone Ring Tooth Missing Fault (wiring, connector, or component)
  • Electrical fault in the monitored circuit
  • Component failure in the described system
  • Control module strategy or calibration issue
  • Control module or software calibration issue (less common—verify tests first)
  • Past repairs or aftermarket parts causing out-of-spec operation

How to diagnose C1141

  1. Scan for C1141 and review freeze frame / pending codes for related faults
  2. Inspect connectors and wiring related to: Wheel Speed Sensor LF Tone Ring Tooth Missing Fault
  3. Compare live data and commanded vs actual values for the affected system (per service information)
  4. Perform circuit tests appropriate to the fault type (continuity, voltage, resistance) before replacing parts
  5. Confirm power and ground integrity at the relevant module or sensor
  6. After repair, clear DTCs and verify under the conditions that originally set C1141

Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.

Severity of code C1141

High: This fault can impact safety-related systems or core drivability—prioritize professional diagnosis.

Can you drive with C1141?

Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.

Avoid heavy acceleration, towing, or long highway drives until the cause of C1141 is confirmed and repaired.

How to fix it (step-by-step)

  1. Start with visual inspection and connector cleaning/tightening where needed
  2. Confirm failure mode with testing—avoid swapping parts without evidence
  3. Repair wiring or replace the failed component per manufacturer procedure
  4. Clear faults, run relearns if required, and road test to confirm

Repair & fix options

  • Clear codes and verify with drive cycle
  • Inspect connectors and wiring first
  • Test component against service limits
  • Clear codes and verify repair with a drive cycle and readiness where applicable
  • Reinspect related monitors if the code returns after repair

Typical repair cost

$100 – $2,500+ depending on cause

Estimated cost breakdown for C1141
Repair type Typical range
Diagnostic And Minor $150 – $650
Common Component Work $300 – $1,400
Major Subsystem Repair $500 – $2,500+
Severe Or Replacement $100 – $400

How to help prevent C1141 in the future

  • Fix new codes early before secondary damage or catalyst stress
  • Keep connectors clean and secure; address rodent or water intrusion in harnesses
  • Use the correct fluids/parts for your vehicle and service intervals
  • Avoid ignoring pending codes after battery work or repairs

When to see a mechanic

Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.

Common mistakes when diagnosing C1141

  • Replacing sensors/modules without verifying wiring and reference voltages
  • Ignoring related codes that identify the real root cause
  • Clearing codes without a verification drive cycle

Common vehicles & notes for C1141

  • Nissan / Hyundai models (common examples—verify for your vehicle)
  • Kia / Mazda applications vary by engine and model year
  • Many other makes—this is a standardized OBD-II definition: Wheel Speed Sensor LF Tone Ring Tooth Missing Fault

C1141 is reported across many platforms including Nissan, Hyundai, Kia, Mazda. Always use VIN-specific service information for testing limits and calibration steps.

Frequently asked questions

What does C1141 mean?

C1141 indicates a fault involving Wheel Speed Sensor LF Tone Ring Tooth Missing Fault, based on what the control module detected during self-tests or live monitoring.

Is it safe to drive with C1141?

If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.

How much does it cost to fix C1141?

Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.

What is the most common cause of C1141?

Most shops start with wiring/connectors and the directly monitored component for “Wheel Speed Sensor LF Tone Ring Tooth Missing Fault,” then expand testing if the fault returns.

Will C1141 clear itself?

It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.

Can a weak battery cause C1141?

Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
