Anti-lock brakes are a critical element of the active safety of any modern vehicle, and Nissan Note This is no exception. When the indicator on the dashboard comes on ABS or the yellow light comes on SLIP, this is a signal that the electronics have entered emergency mode. Owners often encounter an error indicating a malfunction of one of the wheel sensors, which requires immediate attention.
Many car owners are afraid to undertake this procedure on their own, believing that the replacement will require complex diagnostic equipment or a lift. In fact, the suspension design Nissan Note (especially the first generation E11 and second generation E12) makes it relatively easy to get to the sensors. The main thing is to understand that the problem may not be in the element itself, but in the wiring or contamination, so the rush to buy a new part may be premature.
Symptoms of malfunction and diagnosis of the sensor
The first sign that the sensor ABS on your Nissan Note has failed, the indicator light on the instrument panel lights up. In some cases, the system can block the operation of not only the anti-lock braking system, but also the stability control system VDC (Vehicle Dynamics Control), as indicated by the corresponding indicator. This means that the car has lost the ability to prevent skidding under heavy braking.
However, visual signs may not be the only symptom. If the sensor is faulty, you may notice that the brake pedal begins to pulsate even on dry asphalt or, conversely, becomes too “wobbly” and ineffective. In some cases, when accelerating from a standstill, a specific grinding or hum is heard, which disappears when the speed is reduced, which indicates an incorrect interpretation of the wheel speed by the electronic unit.
To accurately confirm the diagnosis, you must use a diagnostic scanner connected to the connector OBD-II. Without reading error codes, you will be operating blindly. Errors associated with sensors usually begin with the prefix C0 and contain information about a specific wheel.

C1101— Open circuit of the ABS sensor (general error) - ❌ Code
C1111— Malfunction of the left front wheel speed sensor - ❌ Code
C1112— Malfunction of the right front wheel speed sensor - ❌ Code
C1113— Malfunction of the left rear wheel speed sensor
It is important to note that on Nissan Note Often the problem is not with the magnetic element itself, but with the oxidation of the contacts in the connector. Therefore, before purchasing a new part, be sure to check the integrity of the wire insulation and the condition of the chip.
⚠️ Attention: If you see an error indicating a sensor malfunction, but the wheel rotates freely and there is no mechanical damage, do not rush to change the part. In 30% of cases, the problem is solved by cleaning the connector and treating the contacts.
Tools and preparation for replacement
To perform work on replacing the sensor, you will need a standard set of tools that most car enthusiasts have. The main difficulty is access to the mounting bracket, which often sticks to the steering knuckle or hub. You will need the keys for 10, 12 and 14, as well as a flathead and Phillips screwdriver for unfastening the wiring clamps.
Be sure to prepare a penetrating lubricant such as WD-40 or LIQUI MOLY, since the sensor mounting bolt is located in an area of constant humidity and dirt. If you are planning a replacement on the rear axle, you may need a wrench to remove the wheel and perhaps a crowbar to carefully remove the stuck sensor.
- 🛠️ Set of open-end and socket wrenches (10 wrench for connector, 14 wrench for sensor)
- 🛠️ Jack and reliable stands (“goats”) for safety
- 🛠️ Penetrating thread lubricant
- 🛠️ Contact cleaner and cleaning cloth
Before starting work, safety must be ensured. The car must be placed on a flat surface, the handbrake is tightened, and stops are placed under the opposite wheels. Remember that the braking system is under pressure and any careless movement may result in injury or component damage.
☑️ Preparing to replace the ABS sensor
Step-by-step instructions for replacing the sensor
The replacement process begins by lifting the vehicle and removing the corresponding wheel. For front sensor Nissan Note you need to find it on the back side of the steering knuckle, towards the center. The sensor is held in place by one bolt. Carefully unclip the wiring from the brackets on the pendant so as not to pull on the cable when removing it.
Unscrew the sensor mounting bolt. If it does not give way, do not use brute force, otherwise you may strip the threads in the aluminum hub housing. Liberally spray the joint with lubricant and wait 10-15 minutes. After unscrewing the bolt, the sensor may fit very tightly. Use a flathead screwdriver to carefully pry it off the housing without touching the wiring.
If the sensor does not come out, try rocking it slightly from side to side. In some cases, using a puller helps, but more often than not, patience and proper rocking technique are enough. Do not try to remove the sensor by pulling on the wire. - this is guaranteed to lead to a break in the internal core.
What to do if the sensor is stuck tightly?
If the sensor does not respond even after treatment with lubricant, you can try to gently heat the sensor location with a hair dryer or torch. The thermal expansion of the metal will help free the jammed element. The main thing is not to overheat the adjacent rubber seals and anthers.
Installing a new sensor is done in the reverse order. Before inserting a new element, be sure to clean the seat from dirt, rust and old lubricant residues. Apply a thin layer of heat-resistant grease to the body of the new sensor to make it easier to remove in the future. Insert the sensor as far as it will go and tighten the mounting bolt to the torque specified in the specification, usually 10-12 Nm.
- ✅ Clean the seat from rust and dirt
- ✅ Check the integrity of the magnetic ring on the hub
- ✅ Insert the new sensor without distortion
- ✅ Connect the connector until you hear a characteristic click
The main idea: Proper cleaning of the seat and use of lubricant when installing a new sensor is the key to long service life and easy dismantling in the future.
Features of front and rear sensors
The design of the front and rear sensors on Nissan Note has its own characteristics. Front sensors often have a longer wire since they are routed through the steering knuckle and subframe. Rear sensors, especially on multi-link suspension (if you have the full version), may be hidden deeper and require removal of protective covers.
It is important to distinguish between active and passive sensors. On earlier versions Nissan Note passive (inductive) sensors were installed that generate a signal due to a magnetic field. New models use active sensors that require power from the control unit. An error in choosing the type of sensor will lead to system inoperability even with proper installation.
When replacing the rear sensor, pay attention to the condition of the wheel bearing. Often the problem lies not in the sensor itself, but in a worn magnetic ring inside the bearing. If the error returns after replacing the sensor, check the play in the hub and the integrity of the magnetic ring.

Comparison of original and analog sensors
When choosing a spare part for Nissan Note The car owner is faced with a dilemma: to buy an original sensor or a high-quality analogue. Original parts from Nissan (the article usually starts with 45610) are characterized by ideal geometry and durability, but their price can be several times higher than their analogues.
High-quality analogues from manufacturers like NTK, Denso or Febi are often no different from the original, since it is these factories that supply the parts to the assembly line. However, the market is flooded with cheap fakes from China that may fail in a couple of months. Saving on security in this case can result in serious problems.
| Manufacturer | Type | Average price (RUB) | Features |
|---|---|---|---|
| Nissan (Original) | Original | 3500 - 5000 | Guaranteed quality, precise geometry |
| NTK / Nissens | OEM Analogue | 1500 - 2500 | Factory quality, best choice for the price |
| Febi / SWAG | Premium Analog | 1800 - 3000 | High quality, often included |
| Low-cost brands | Budget | 500 - 900 | Risk of rapid failure, unstable signal |
Please note that the wire length may vary between analogs. If the wire is too short, you will have to extend it, which is unacceptable for high-precision signals. If the wire is longer, lay it carefully, avoiding tension when turning the steering wheel.
⚠️ Attention: Never use cheap Chinese sensors without a brand. They often have an incorrect air gap, which will cause the ABS system to operate falsely even on a smooth road.
Problems with wiring and contacts
One of the most common causes of false alarms of the ABS system is Nissan Note It is not the sensor itself, but damage to the wiring. The wires run near the wheels, where they are exposed to water, salt, reagents and stones. Over time, the insulation cracks and the wire shorts to ground or breaks.
Carefully inspect the wire along its entire length from the sensor to the connector going towards the body. Pay special attention to the bends and the entrance to the connector. If you see exposed wires, they need to be insulated or the section of wiring needs to be replaced. The use of ordinary electrical tape is not recommended here - it is better to use heat shrink.
It's also worth checking the connector itself. The contacts inside may oxidize, which will lead to high circuit resistance. Clean the contacts with a special cleaner and apply conductive lubricant. If the connector is mechanically damaged, it is better to replace it entirely, as poor contact can lead to overheating.
Before installing a new sensor, be sure to check the integrity of the wire with a tester, testing the circuit for an open circuit and a short to ground. This will save time and money if the problem is not with the sensor.
Error reset and system check
After replacing the sensor, the error on the dashboard may not disappear immediately. This is normal, since the system requires confirmation of serviceability. You need to reset the error codes through the diagnostic scanner. If you don't have professional equipment, you can try disconnecting the battery terminal for 15-20 minutes, but this is not always effective for ABS systems.
The best way is to use an adapter ELM327 and an application on a smartphone (for example, Nissan Consult or Car Scanner). Connect to the control unit, select the “Chassis Systems” or “ABS” section, and press the “Error Reset” button. After this, the indicators should go out.
After the reset, be sure to test drive it. Get up to speed 20-30 km/h and brake gently several times. Make sure that the brake pedal does not pulsate for no reason and that the ABS light does not come on. If the error returns, it means the problem is deeper - the ABS unit or the hub magnetic ring may be faulty.
⚠️ Attention: If the error resets, but lights up again after the first trip, it means you have not eliminated the root cause. In this case, in-depth diagnostics are required by measuring the sensor resistance and checking the signal oscillogram.
The main idea: Resetting the error without diagnostics can only give a temporary effect. Make sure all connections are secure and the sensor itself is in good working order before calling the repair complete.
FAQ: Frequently asked questions from Nissan Note owners
Is it possible to drive with the ABS light on?
Technically, the car continues to brake as the main hydraulic system operates. However, the anti-lock braking system (ABS) and vehicle stability control (VDC) are disabled. This means that during emergency braking, the wheels may lock and the car may lose control. You can drive, but be extremely careful.
How much does it cost to replace a sensor at a service center?
The cost of work on average ranges from 1,500 to 3,000 rubles per sensor, depending on the region and complexity of access. If wheel rim removal or other additional work is required, the price may increase. The spare parts themselves cost from 1,500 rubles for a high-quality analogue.
Why does the error return immediately after replacement?
This may be due to damaged wiring, poor contact in the connector, or a faulty magnetic ring in the wheel bearing. It is also possible that you installed the wrong type of sensor (active instead of passive or vice versa).
Do I need to replace both sensors on the same axis?
No, only the faulty sensor needs to be replaced. However, if one of them fails due to age or operating conditions, it makes sense to check the condition of the second. But it is not necessary to change them in pairs, like brake pads.
How to check a sensor with a multimeter?
For passive sensors, you need to measure the resistance between the connector pins. The normal value is usually between 1000 and 2500 ohms. For active sensors, you need to check the presence of supply voltage (usually 5V or 12V) when the ignition is turned on.
