Nissan Almera Classic (also known as Nissan Almera B10 or Samsung SM3 in some countries) is a popular sedan that is valued for its reliability and ease of maintenance. However, even this model has problems with the system over time ABS (Anti-lock Braking System). One of the most common malfunctions is the failure of ABS sensors, which leads to loss of functionality of the anti-lock braking system and the warning lamp on the dashboard lights up.

In this article we will look at how to independently diagnose a malfunction of the ABS sensor on Almera Classic, what errors indicate its breakdown, how to check its functionality with a multimeter and replace the part without contacting service. We will also consider typical causes of failure, prices for original and similar spare parts, and give recommendations for prevention.

Signs of a malfunctioning ABS sensor on Nissan Almera Classic

The first and most obvious symptom of the problem is ABS light on on the dashboard. However, this does not always mean that the sensor is broken. The system may also respond to other faults: broken wiring, damage to the ring gear on the hub, or failure of the ABS control unit. To accurately determine the cause, you need to pay attention to additional signs:

  • 🔴 ABS light comes on when driving and does not go out after restarting the engine.
  • 🚗 Wheels locking during sudden braking (ABS does not work).
  • 📊 Errors in the on-board computer, for example, C1130 (front right wheel sensor malfunction) or C1140 (rear left).
  • 🔊 Extraneous sounds from the hub area (grinding, tapping) - may indicate damage to the ring gear.

If the ABS light only comes on at high speeds or on rough roads, the problem often lies in oxidized contacts or damaged wiring. In this case, it is enough to clean the connectors and check the integrity of the cables. If the error appears constantly, most likely the sensor itself or its mechanical damage is to blame.

⚠️ Attention: Ignoring an illuminated ABS light is dangerous! If the system fails, the wheels may lock during emergency braking, resulting in loss of control, especially on slippery roads.
📊 How often do you check the ABS system in your car?
  • Only when the lamp comes on
  • Once a year during maintenance
  • Before the winter season
  • Never checked

Location of ABS sensors on Nissan Almera Classic B10

On Almera Classic are installed four ABS sensors - one on each wheel. They are attached to the wheel bearings and read wheel speed data from the ring gear. Location:

  • 🔧 Front sensors — are located on the steering knuckles, next to the ball joints. They are accessible after removing the wheels.
  • 🔧 Rear sensors — installed on the rear beam, closer to the hub. Replacement may require removal of the brake drum.

Each sensor is connected to the ABS control unit by a separate wire that runs along the suspension. Often problems arise with the wiring - it rubs against suspension elements or rusts at the connections.

Important: on Almera Classic before 2010, the ABS sensors of the front and rear axles are interchangeable only on one side (left/right). After restyling (2010–2012), differences in connectors are possible - check the article numbers by VIN code!

How to check the ABS sensor with a multimeter?

Before replacing the sensor, it must be checked for functionality. For this you will need multimeter with resistance measurement mode (200 Ohm - 2 kOhm) and, preferably, oscilloscope (for advanced diagnostics). Verification algorithm:

  1. Removing the sensor: Disconnect the power connector and unscrew the sensor with a key 10 mm (front) or 8 mm (rear).
  2. Visual inspection: Check the integrity of the housing for cracks and corrosion. Clean contacts from oxidation.
  3. Dial: Connect the multimeter probes to the sensor terminals. The resistance of a working sensor should be within the range 800–1400 Ohm.
  4. Insulation check: Measure the resistance between any sensor terminal and its body. The readings should tend to infinity (no short circuit).

If the sensor resistance is lower 700 Ohm or higher 1500 Ohm, it is faulty. Also a sign of failure is open circuit (the multimeter shows OL).

Clean the connector contacts from oxidation|Test the sensor with a multimeter (800–1400 Ohm)|Check the insulation (no short circuit to the body)|Inspect the ring gear on the hub (no chips)-->

⚠️ Attention: When checking the rear sensors for Almera Classic with ABS Bosch 5.3 (installed before 2008) resistance may vary - normal range 1000–1600 Ohm. Check the details in the manual for your VIN.

Step-by-step instructions for replacing the ABS sensor

Replacing the ABS sensor with Nissan Almera Classic does not require special skills, but will require an inspection hole or a lift. Let's look at the process using an example front left sensor:

  1. Preparation: Stop the engine, apply the handbrake and remove the negative terminal from the battery. Jack up the car and remove the wheel.
  2. Sensor access: Disconnect the power connector (press the latch and pull it up). Clean the sensor mounting area from dirt.
  3. Dismantling: Key on 10 mm Unscrew the sensor mounting bolt. Carefully remove it from the hole in the hub.
  4. Installing a new sensor: Insert the new part into the seat, secure with a bolt (tightening torque 8–10 Nm). Connect the connector.
  5. Check: Install the wheel, lower the car and start the engine. The ABS light should go out after a short self-test (5-10 seconds).

For replacement rear sensor Additionally, it may be necessary to remove the brake drum. On models with ABS Bosch 5.7 (after 2008) sensors are mounted on 8mm bolts, and the connectors have a different shape - do not mix up the sides!

💡

Before installing a new sensor, apply a thin layer to its seat copper grease - this will prevent corrosion and make future replacement easier.

Typical ABS errors on Nissan Almera Classic and their decoding

When diagnosing with a scanner (for example, ELM327 or Launch CReader) the ABS system can generate various fault codes. Below is a breakdown of the most common errors for Almera Classic:

Error code Description Possible reason
C1130 Front right wheel speed sensor malfunction Damaged sensor, broken wiring, corroded connector
C1140 Malfunction of the rear left wheel speed sensor Wear of the ring gear, contamination of the sensor with metal shavings
C1111 ABS sensor signal low Poor contact in the connector, damage to the wire shielding
C1118 Inconsistency between front and rear axle sensor signals The ABS unit or sensor on one of the axles is faulty

If the error does not clear after replacing the sensor, check:

  • 🔌 Wiring integrity from the sensor to the ABS block (often chafing near the suspension arm).
  • 🛠️ Ring gear condition on the hub - chips or corrosion lead to failures in signal reading.
  • 🔧 Voltage at the ABS unit connector (must be 12 V on the power contact).
What should I do if the error returns after replacing the sensor?

If the fault code appears again, the problem may lie in ABS control unit or wiring. In this case it is recommended:

1. Check the voltage at the ABS unit connector (contact 15 - plus, 4 - mass).

2. Inspect the shielding braid of the sensor wire - it often rubs against body elements.

3. Conduct diagnostics of the ABS unit using specialized equipment (for example, Bosch KTS).

Cost of spare parts and replacement labor

Price for ABS sensors for Nissan Almera Classic depends on the manufacturer and type (front/rear). Below are the current prices for 2026:

Sensor type Original (Nissan) Analogs (Bosch, TRW, Febi) Cost of work (service station), rub.
Front 2 500 — 3 200 1 200 — 2 000 800 – 1,500 (for one wheel)
Rear 2 200 — 2 800 900 — 1 800 1,000 - 1,800 (drum removal)

Replacing it yourself will only cost the cost of the sensor. However, if the problem is ABS block, its replacement or repair will be more expensive:

  • 💰 ABS block (original) — 15,000 - 25,000 rub.
  • 💰 Unit repair (reflashing, replacing capacitors) — 5,000 - 10,000 rub.
💡

When purchasing analogs of ABS sensors, give preference to brands Bosch, TRW or ATE - they provide compatibility with electronics Almera Classic and have a minimum percentage of defects.

ABS fault prevention

To extend the life of ABS sensors by Nissan Almera Classic, follow these simple guidelines:

  • 🚿 Wash the wheel arches in winter - salt and reagents accelerate corrosion of sensors and wiring.
  • 🔧 Check the fastening of the wires — they should not hang out or rub against the suspension.
  • 🔍 Inspect the connectors for oxidation once a year (especially before winter).
  • 🛑 Avoid hard braking on gravel - stones can damage the ring gear.

Also useful once every 20,000–30,000 km carry out ABS diagnostics scanner, even if the lamp is not lit. This will help identify hidden problems at an early stage.

FAQ: Frequently asked questions about ABS sensors on Nissan Almera Classic

Is it possible to drive with a faulty ABS sensor?

Technically yes, but it's dangerous. ABS will not work on a damaged wheel, which will lead to the brakes locking during emergency braking. In addition, on some versions Almera Classic ABS malfunction disables the system EBD (distribution of braking forces), which further worsens the braking distance.

How to reset the ABS error after replacing the sensor?

On most Almera Classic the error is reset automatically after 2–3 cycles of turning the ignition on/off. If the lamp remains on:

  1. Disconnect the battery terminal for 10 minutes.
  2. Drive 5–10 km at a higher speed 40 km/h — the system will perform self-diagnosis.
  3. If the error persists, use the diagnostic scanner to force a reset.
What is the difference between ABS sensors before and after 2010?

On Almera Classic before 2010 the system was installed ABS Bosch 5.3, after - Bosch 5.7. Main differences:

  • Different connection connectors (on Bosch 5.7 - flatter connector).
  • The self-diagnosis algorithm has been changed (on new versions the ABS lamp goes out faster).
  • The sensors are not interchangeable - they have different resistances and housing shapes.

Check compatibility by VIN code or catalog number!

Is it possible to clean the ABS sensor instead of replacing it?

If the problem is pollution (such as metal shavings on the magnetic core), the sensor can be cleaned alcohol solution and a soft brush. However, if the housing is damaged, wires are torn off or the resistance is changed, replacement is required. Remember: Even after cleaning, the sensor may malfunction due to internal wear.
