By Ezra Lane When your Nissan displays the C1105 code, it means there’s a fault in the rear right wheel speed sensor circuit, which is crucial for the ABS to function correctly. This issue could stem from a defective sensor, wiring problems, or blockage caused by dirt. Checking and possibly replacing the sensor or cleaning the affected area generally resolves the problem. An ABS warning light usually accompanies this malfunction, and you might notice decreased braking performance or unexpected traction control activation. Address this error promptly to prevent further complications. In exploring the details further, you’ll learn specific steps to diagnose and fix this error safely.
C1105 Nissan Code Meaning
The C1105 code on a Nissan indicates a malfunction in the rear right wheel speed sensor circuit, affecting the ABS.
Causes include a faulty sensor, wiring issues, or contamination.
Inspect, clean, or replace components to restore proper function and maintain stable braking performance.
Error Code C1105 Symptoms
If your Nissan shows the C1105 error code, you’ll see the ABS warning light on your dashboard. This code means there’s a problem with the rear right wheel sensor, which can cause certain issues with your car.
Look for these signs:
- Traction Control Turns On Unexpectedly: The traction control system might activate when it shouldn’t. This can be unsettling if the road is clear and dry.
- Brakes Feel Different: Your brakes mightn’t work as they should. The car could take longer to stop, which is risky when driving fast or in emergencies.
- Strange Noises When Braking: Listen for grinding or scraping sounds when you press the brakes. This could mean the brake parts aren’t working together properly because of the sensor problem.
- Car Pulls to One Side: If the car pulls to one side when braking, it might mean the braking force isn’t even on all wheels, often due to sensor issues.
Causes of Nissan C1105 Fault Code
If your Nissan shows the C1105 error code, it often means there’s a problem causing unwanted traction control activation or uneven braking.
Here are some possible reasons:
- Bad Rear Right Sensor: This sensor checks how fast the wheel spins. If it’s not working, your car’s braking and stability systems could act up, leading to the C1105 code.
- Broken Wires or Connectors: If wires are damaged, the sensor may not send the right signals. Look for any wear or damage that might stop the sensor from working.
- Sensor Not Aligned Properly: If the sensor isn’t in the right place or is loosely attached, it can’t measure wheel speed correctly. This can happen over time or after a bump.
- Dirt or Debris: If dirt or mud blocks the sensor, it mightn’t work well. Cleaning it regularly can help keep it running smoothly.
Tools Needed to Diagnose
To diagnose the C1105 Nissan code, you’ll need some specific tools. These help find the problem with the rear right sensor 2 in your car’s brake system. Here’s what you need:
- Diagnostic Scanner: Use this to read the C1105 code and check the problem. Ensure the scanner works with Nissan vehicles.
- Multimeter: This tool checks if electricity is flowing properly to the sensor and its wires. Make sure the power to the sensor is okay and there are no breaks in the wires.
- Vehicle-specific Wiring Diagram: This diagram helps you find and follow the wires linked to the rear right sensor 2. It guides you through the wiring system.
- Basic Hand Tools: Have socket sets and wrenches ready. You may need these to take out and put back the sensor.
Also, keep a cleaning kit nearby. Sometimes, dirt and debris can affect the sensor.
How to Fix C1105 Nissan Error Code – Step by Step
Step 1:
Gather the necessary tools and use a diagnostic scanner to confirm the presence of the C1105 error code on your Nissan. This ensures you’re addressing the correct issue and not a misdiagnosis.
Step 2:
Inspect the rear right sensor 2 for any visible damage, corrosion, or misalignment. Carefully examine the wiring and connectors, checking for breaks or loose connections that could disrupt sensor function.
Step 3:
If you find dirt or debris around the sensor, clean the area thoroughly. Contamination can impede the sensor’s ability to accurately read wheel speed, which is vital for the ABS system’s performance.
Step 4:
Should you discover any damaged sensor or components, replace them with compatible parts specific to your Nissan model. Using the correct parts is crucial to maintain system integrity and functionality.
Step 5:
After replacing any faulty parts, use the diagnostic scanner to reset the ABS system. Finally, take your Nissan for a test drive to ensure the repairs have cleared the error code and that the braking system functions normally.
Common Diagnosis Mistakes
When you see the C1105 error code on a Nissan, don’t immediately assume the sensor is the problem. Here are some common mistakes to avoid:
- Check the Wiring: Before blaming the sensor, look at the wiring and connectors. Damage or corrosion here can make it seem like the sensor is faulty.
- Clean the Sensor Area: Dirt or debris around the sensor can cause wrong readings and trigger the C1105 code.
- Look for Other Codes: Use a scanner to find any other codes. There might be more than one issue affecting the ABS system.
- Check Sensor Placement: Make sure the sensor is in the right position and properly attached. If it’s not, it mightn’t work correctly and cause errors.
C1105 Nissan Repair Cost
Repairing the C1105 Nissan code can cost between $150 and $400. The price depends on the specific problem and parts needed. Costs vary because of different labor rates and part prices, which change based on where you live and your Nissan model.
In cities with high living costs, expect prices on the higher side of this range.
Labor costs for diagnosing and fixing the rear right sensor circuit error can differ. Some errors are easy to diagnose, while others need more testing, which takes more time and raises labor costs.
If the rear right sensor 2 needs replacing, the part itself might cost between $50 and $200. This range is due to the choice between original Nissan parts or cheaper aftermarket parts.
It’s wise to get multiple quotes from repair shops. This helps you understand the prices better and might show you different ways to fix the problem.
Related Error Codes on Nissan
If you’re seeing error codes like C1100, C1101, and C1102 in your Nissan, it means there might be issues with the ABS system. These codes, along with C1105, suggest problems not just with one sensor, but possibly the whole anti-lock braking system.
If C1105 appears with codes like C1106 or C1171, this can mean there are problems affecting more than one wheel sensor or the entire wheel speed system. It’s not just one part that’s acting up. Ignoring these can lead to more issues with your car’s braking.
The C1110 code might mean there are electrical problems in the ABS control unit. This is important because this unit controls the whole ABS system and if it’s not working right, the ABS might not work at all.
Here’s a quick look at the codes and what they mean:
| Code | Description | Meaning |
|---|---|---|
| C1100 | ABS Sensor Circuit | General ABS issue |
| C1101 | Left Front Sensor | Checks front-left wheel |
| C1102 | Right Front Sensor | Checks front-right wheel |
| C1106 | Rear Left Sensor 2 | Checks rear-left wheel |
| C1171 | Wheel Speed Sensor | General wheel speed problem |
Fixing these issues helps keep your car’s ABS working well.
