Error C1105 on the dashboard Nissan - one of the most common problems associated with the system ABS (anti-lock brake system). This code indicates a fault in the circuit Right front wheel speed sensor, but the reasons can be much deeper - from a banal wire break to failure of the control unit. Owners Qashqai, X-Trail And Juke encounter it most often, especially after 100,000 km or when operating in an aggressive environment (salt, dirt, moisture).

Unlike engine errors (eg. P0300), which immediately hit the wallet due to increased fuel consumption, C1105 seems “harmless” - the car drives, brakes, but it cannot be ignored: when the error is activated, ABS is disabled, and this directly affects safety during emergency braking or on slippery roads. In this article, we’ll look at how to accurately diagnose the problem, which parts to check first, and when it’s worth going to a service station, and when you can handle it on your own.

What does error code C1105 mean on Nissan?

Code C1105 in the self-diagnosis system Nissan stands for “Front right wheel speed sensor circuit malfunction”. This is part ABS, which is responsible for controlling the speed of rotation of the wheels and preventing them from blocking when braking. If the control unit (ECU) detects the absence of a signal or its instability, it records an error and turns off the system.

It is important to understand that C1105 - this is not a death sentence for the sensor. The reasons may be different:

  • 🔌 Open or short circuit in wiring (most often in the area of the wheel arch or sensor connector).
  • 🛠️ Damage to the sensor itself (corrosion, mechanical stress, internal breakage).
  • 🔄 Contamination or damage to the gear rotor (dirt, rust, chipped teeth).
  • 🖥️ ABS control unit malfunction (rare, but occurs during power surges or after unqualified repairs).

Interesting fact: on Nissan Qashqai J10 And X-Trail T31 error C1105 sometimes appears after replacing the wheel bearing, if the technician forgot to reinstall the ABS sensor or damaged it during dismantling. Also, the code may “light up” after strong impacts on the wheel (for example, when it falls into a hole), when the sensor rotor moves.

Symptoms of error C1105: how does it manifest itself?

The main sign is ABS light on on the dashboard, but there are other “signals” that will help confirm the diagnosis:

  • ⚠️ ABS light comes on when driving and does not go out (or flashes when turning).
  • 🚗 Braking distance increases, especially on wet or icy roads.
  • 🔊 Extraneous sounds are heard (grinding, crackling) from the right front wheel when braking.
  • 📊 On-board computer shows incorrect speed or resets it to zero while moving.

On some models (for example, Nissan Juke) error C1105 may be accompanied code C1130 (left front wheel sensor malfunction) - this indicates a system problem, such as unstable mains voltage or damage to the main ABS wiring harness.

⚠️ Attention: If together with C1105 the lamp came on ESP (stability control system), operate the vehicle it's impossible - this means that all active safety systems are disabled. In this case, urgent diagnosis is required!

Step-by-step diagnosis of error C1105

Before going to the service station, you can check the most likely causes yourself. For this you will need:

  • 🔧 Multimeter (to check the resistance of the sensor and circuit).
  • 🔍 Flashlight and mirror (for inspecting the sensor and wiring).
  • 📱 Scanner ELM327 or application Torque (to read errors and ABS parameters).

Step 1: Visual inspection of the sensor and wiring

Right front wheel ABS sensor on most Nissan located on the hub, next to the brake disc. Inspect:

  • 🔌 Sensor connector — whether there is oxidation, moisture or damage.
  • 🧲 The sensor itself - cracks, corrosion, traces of impacts.
  • 🌀 Toothed rotor (on the hub) - integrity of teeth, absence of dirt or rust.

Step 2: Check the sensor resistance

Disconnect the sensor connector and measure the resistance between its contacts with a multimeter. Normal values for Nissan:

Model ABS Sensor Resistance (Ohm) Note
Qashqai J10/J11 800–1400 Ohm With a break - infinity, with a short circuit - 0 Ohm
X-Trail T31/T32 1000–1600 Ohm Test at 20°C
Juke F15 700–1300 Ohm Sensitive to moisture in the connector

Step 3: Check the power circuit

If the sensor is working properly, check the wiring from the connector to the ABS unit (usually located under the hood or in the passenger compartment near the pedal assembly). Check the circuit for opens and short circuits. Please note:

  • 🔥 ABS fuse (on Qashqai — F37 (10A) in the block under the steering wheel).
  • 🔌 ABS unit connector - oxidation or poor contact.

Common causes of error C1105 and how to fix them

Let's look at the most common “culprits” of the error and how to eliminate them.

1. ABS sensor is damaged

If the sensor shows a break or resistance outside the norm, it must be replaced. The cost of the original sensor for Nissan - from 2,500 to 5,000 rubles, analogues - from 1,200 rubles. When replacing:

  • 🔧 Use copper paste to protect contacts from corrosion.
  • 🔩 Tighten the fastening bolt firmly 8–10 Nm (do not overtighten!).

2. Break or short circuit in the wiring

The wires from the sensor to the ABS unit often rub against the suspension or wheel. Inspect the harness for:

  • 🕳️ Scuffed insulation (especially in bend areas).
  • 💧 Traces of moisture (can cause corrosion and short circuit).

If the wire is damaged, it can be solder (with mandatory heat shrink insulation), but it is better to replace the entire harness.

3. Contamination or damage to the gear rotor

The rotor (impulse ring) must be clean, free of chips and rust. Clean it up wire brush and check the gap between the sensor and the rotor - it should be 0.5–1.5 mm. If the rotor is deformed, the hub will need to be replaced.

4. Malfunction of the ABS control unit

If the sensor and wiring are fine, but the error remains, the problem may be in the ABS unit. In this case:

  • 🔄 Try it reset errors scanner (sometimes it helps).
  • 🔧 Swipe flashing the block (specialized equipment required).
  • 🚗 If the block “died”, it will have to be replaced (cost - from 15,000 rubles).

How to reset error C1105 after repair?

After eliminating the cause, the error must be reset. There are several ways:

1. Reset via scanner

Connect ELM327 or diagnostic adapter, select section ABS and run the command Clear DTC. On some models (Nissan Almera N16) may be required initialization loop:

  1. Start the engine.
  2. Drive 10–15 meters forward.
  3. Turn off the ignition for 10 seconds.
  4. Run again and the error should disappear.

2. Reset by disconnecting the battery

If you don’t have a scanner, you can try to “reset” the error by removing the battery terminal for 15–20 minutes. However, this method does not always work - modern Nissan store errors in the non-volatile memory of the ABS unit.

3. Reset via key combination

On some models (for example, Nissan Tiida) the error can be reset without a scanner:

  1. Turn on the ignition (do not start the engine).
  2. Press and hold the button TRIP (daily mileage reset).
  3. After 5 seconds press the button MODE 3 times.
  4. Let go TRIP — errors should be reset.
⚠️ Attention: If the error C1105 appears again after a reset, the problem is not resolved! Don't ignore it - it could lead to complete ABS failure in a critical situation.

When to contact a service station?

Not all problems with C1105 you can decide on your own. Contact a specialist if:

  • 🔧 You replaced the sensor and wiring, but the error remains.
  • 🖥️ The scanner shows additional ABS unit errors (C1145, U1000).
  • 🚗 After repair the lamp came on ESP or Check Engine.
  • 🔌 No experience with a multimeter or diagnostic equipment.

At a service station for diagnostics C1105 use:

  • 🔍 Oscilloscope — to check the sensor signal in the speaker.
  • 📡 Specialized scanners (Launch, Bosch KTS) - for deep diagnostics of the ABS unit.
  • 🔧 Test sensors - to exclude malfunction of the original sensor.

The average cost of diagnostics in the service is: 1,500–3,000 rubles. If the ABS unit needs to be replaced, be prepared to pay between 20,000 rubles (with work).

💡

If error C1105 is accompanied by vibrations when braking or the car pulls to the side, the problem may be in the wheel bearing - its wear often damages the ABS sensor.

Prevention of error C1105

To avoid reappearance C1105, follow these simple guidelines:

  • 🚿 Wash the wheel arches in winter - salt and reagents accelerate corrosion of the sensor and wiring.
  • 🔧 Check the sensor fastening after replacing bearings or brake discs.
  • 🛠️ Use dielectric grease on the contacts of the ABS connectors.
  • 📊 Read errors regularly (every 10,000 km) - this will help identify the problem at an early stage.

On Nissan Qashqai J11 And X-Trail T32 ABS sensors often fail due to poor quality roads - shocks to the suspension are transmitted to the hub and damage the rotor. If you often drive off-road, install crankcase protection and avoid sharp impacts on the wheels.

💡

Before purchasing a new ABS sensor, check its part number using the vehicle's VIN code - even on the same model Nissan There may be sensors with different resistances!

FAQ: Frequently asked questions about error C1105

Is it possible to drive with error code C1105?

Technically yes, but ABS will not work. This is dangerous during emergency braking, especially on slippery roads. The error may also mask more serious problems (for example, a malfunction of the ABS unit).

Why does error code C1105 appear after replacing the wheel bearing?

Most often, the ABS sensor is damaged when removing the hub (by hitting or pinching the wire). Also, the technician may have forgotten to reinstall the sensor or incorrectly adjusted the gap between the sensor and the rotor.

How can you tell the difference between a faulty sensor and a wiring problem?

If the sensor resistance is normal (for example, 1,200 Ohms), but the signal does not go to the ABS unit, there is a problem in the wiring. If the resistance is 0 or infinity, the sensor is faulty.

Could error C1105 cause other problems?

Yes. For example, on Nissan Juke a faulty ABS sensor can lead to false ESP activation or Incorrect operation of cruise control (if it is connected to the brake system).

How much does it cost to repair error C1105?

The cost depends on the reason:

  • Replacing the sensor - 1,500–5,000 rub. (part + work).
  • Wiring repair - 2,000–4,000 rub.
  • Replacing the ABS block - 20,000–40,000 rub.
