C1193 Code: Meaning, Symptoms, Causes & Fix

Overview

Symptoms

• ABS/traction light on
• longer braking intervention
• reduced stability control performance

Common causes

• Disconnected or loose connector affecting speed wheel sensor rf input short circuit to ground
• Broken terminal inside harness
• Connector pin damage/corrosion or harness stress near related components

How to diagnose C1193

1. Confirm C1193 and capture freeze-frame data with a professional scan tool.
2. Inspect wiring, connectors, and grounds related to speed wheel sensor rf input short circuit to ground for obvious defects.
3. Use a continuity test from module pin to component to identify opens/high resistance.
4. Check for related DTCs to identify the root-cause chain before replacing parts.
5. After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code C1193

Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.

Can you drive with C1193?

Most vehicles can be driven short-term with C1193, but postpone heavy load/highway driving until repaired.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

1. Repair obvious wiring/connector faults first to prevent repeat parts replacement.
2. Address the root fault mode (open) in the speed wheel sensor rf input short circuit to ground circuit/system.
3. Apply the required relearn/adaptation procedure if specified by service information.
4. Road-test and verify C1193 remains cleared under the conditions that originally set the code.

Fix options

• Repair open circuit and secure connector lock.
• Restore continuity and verify pin tension.
• Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$240-$1200

Common mistakes when diagnosing C1193

• Replacing parts without verifying voltage, ground, and signal integrity first.
• Ignoring related stored/pending codes that indicate upstream faults.
• Skipping post-repair verification drive cycle and readiness checks.

C1193 in common vehicles

C1193 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes C1193?

C1193 is commonly set by open faults affecting speed wheel sensor rf input short circuit to ground.

How much does it cost to fix C1193?

For C1193, repair costs are typically $240-$1200 depending on exact root cause, labor rates, and part quality.

Can I clear C1193 without repair?

You can clear C1193 temporarily, but the code usually returns until the underlying fault is corrected.
