Nissan Almera Classic (especially in bodies B10 And N16) is one of the most popular foreign cars on the secondary market in Russia and the CIS. But even this reliable machine has weak points, and one of them is ABS sensors. The front right sensor fails more often than others due to its close location to the wheel and constant exposure to dirt, moisture and vibration. If the indicator on the dashboard comes on ABS, and the diagnostics showed an error related to the right front wheel - this article will help you understand the problem without extra costs.

We will tell you in detail how check ABS sensor on Almera Classic multimeter, what original and similar articles are suitable for replacement, how to avoid mistakes during installation and why sometimes the problem lies not in the sensor itself, but in the wiring or wheel bearing. You will also find step-by-step instructions with photos, spare parts compatibility table and answers to frequently asked questions from owners.

Signs of a malfunction of the front right wheel ABS sensor

The first signal of a problem with the ABS sensor on Nissan Almera Classic - this is, of course, ABS light on on the dashboard. However, there are other symptoms that will help more accurately diagnose the problem. front right sensor:

  • 🚨 ABS light comes on when driving, especially on uneven roads or when turning right. This is due to the fact that the sensor loses the signal when vibrations or changes in the angle of inclination.
  • 🔄 Spontaneous activation of ABS on dry roads with light braking. The system mistakenly perceives the sensor signal as a wheel lock.
  • 📉 Deterioration of braking dynamics. If the sensor fails completely, the ABS is disabled and the braking distance on slippery roads increases.
  • 🔧 Error C1130 or C1145 during diagnostics (codes may vary depending on the year of manufacture and version of the ECU).

It is important to understand that other malfunctions can cause similar symptoms: damaged wiring, oxidized contacts, worn wheel bearing or even faulty ABS unit. Therefore, before replacing the sensor, be sure to check comprehensive diagnostics.

⚠️ Attention! If on Almera Classic ABS light came on simultaneously with the brake system lamp (red exclamation mark), this may indicate a critically low brake fluid level or a faulty master cylinder. In this case, replacing the sensor will not solve the problem!
📊 How often do you check the ABS system on your car?
  • Only when the light comes on
  • Once a year during maintenance
  • Before the winter season
  • Never checked

How to check the ABS sensor on a Nissan Almera Classic with a multimeter

Before purchasing a new ABS sensor be sure to check the old one - often the problem lies in the wiring or connectors. For diagnostics you will need multimeter (in ohmmeter mode) and jack (or inspection hole).

Check procedure:

  1. Remove the wheel and locate the ABS sensor on the hub. On Almera Classic it is located next to the brake disc and is secured with one 10mm bolt.
  2. Disconnect the connector sensor Clean the contacts from dirt and oxidation (you can use WD-40 or alcohol).
  3. Measure resistance sensor:
    • 🔧 Normal resistance for Nissan Almera Classic: 800–1400 Ohm.
    • 🚫 If resistance 0 ohm - short circuit if ∞ (infinity) - break.
  • Ring the wiring from the sensor connector to the ABS unit (located under the hood on the driver's side). The resistance should be close to 0 ohms.

    • If the sensor shows normal resistance, but the ABS light is still on, check the wheel bearing. A worn bearing increases the gap between the sensor and the drive disk, resulting in signal loss. Also inspect driving disk (comb) on the hub - if the teeth are worn or damaged, the sensor will produce false signals.

    Step-by-step replacement of the front right wheel ABS sensor

    Replacing the ABS sensor with Nissan Almera Classic - a procedure that you can handle on your own 30–60 minutes. The main thing is to be careful and not damage the wiring. You will need:

    • 🔧 Key or head on 10 mm (for the sensor mounting bolt).
    • 🔨 Flat-head screwdriver (for removing the connector lock).
    • 🧴 WD-40 or similar penetrating lubricant.
    • 🧲 Magnet (so as not to drop the bolt when unscrewing).

    Replacement instructions:

    1. Raise the car on a jack and remove the right front wheel. Place stops under the threshold for safety.
    2. Clean the area around the sensor from dirt. The sensor is located on the hub, next to the brake caliper.
    3. Disconnect the connector sensor To do this, press the latch and pull the connector to the side. If it does not budge, carefully pry it off with a screwdriver.
    4. Unscrew the fastening bolt sensor (key 10). Be careful - the bolt may be very soured. If it doesn't work, process it WD-40 and wait 5-10 minutes.
    5. Remove the old sensor and compare it with the new one. Make sure the length and shape match.
    6. Install a new sensor, secure with a bolt and connect the connector. Do not use excessive force when tightening the bolt - you may strip the threads.
    7. Check the system operation. Start the car and drive at speed 30–40 km/h, slowing down slightly. The ABS light should go out.

    If the ABS light remains on after replacing the sensor, clear the errors using a diagnostic scanner (for example, ELM327) or disconnect the battery terminal for 10-15 minutes.

    What to do if the ABS sensor mounting bolt is broken?

    If a bolt breaks off while unscrewing, don't panic. It can be drilled out with an 8mm drill and then a new thread can be cut with an M10×1.25 tap. As a last resort, use a M10x1.5 threaded bolt (it's a little larger, but will do). After installing the new bolt, treat it Lithol or graphite lubricantto avoid re-souring.

    Common mistakes when replacing an ABS sensor and how to avoid them

    Even experienced car owners sometimes make mistakes when replacing the ABS sensor with Nissan Almera Classic. Here are the most common ones and how to prevent them:

    • 🔌 Connector damage when disconnected. Never pull on the wires - only on the connector body! If the latch is broken, use a flathead screwdriver to carefully pry the latch up.
    • 🔧 Fastening bolt tightening. The threads in the hub are soft and the bolt can be easily stripped. Tighten firmly 10–15 Nm (or “by hand” without fanaticism).
    • 🧲 Installing the sensor with a skew. If the sensor does not fit tightly to the drive disc, the signal will be unstable. Check the gap - it should be 0.5–1 mm.
    • 🔋 Forgot to reset error. After replacing the sensor, the error in the ABS unit remains. If you do not reset it using a scanner or removing the terminal, the lamp will light even with a working sensor.

    Another common problem is dirt getting between the sensor and the drive disk. Before installing a new sensor, thoroughly clean the surface of the hub and disc from metal shavings and rust. Use carbcleaner or brake fluid for cleaning.

    💡

    If, after replacing the ABS sensor, the lamp comes on only on bumps or when turning, the problem is most likely wiring or connector. Check the circuit for open or short circuit!

    Cost of work to replace the ABS sensor in the service

    If you are not confident in your abilities or do not have time to repair it yourself, you can contact a car service. The cost of replacing the front right ABS sensor with Nissan Almera Classic varies depending on the region and service station level:

    Frequently asked questions about the ABS sensor on Nissan Almera Classic

    Is it possible to drive with a faulty ABS sensor?

    Technically yes, but this unsafe. ABS is disabled and the wheels may lock during emergency braking, especially on wet or icy roads. Tire wear also increases. If the sensor fails, replace it as soon as possible.

    Why does the light still come on after replacing the ABS sensor?

    There are several reasons:

    • The error in the ABS unit has not been reset (you need to use a scanner or remove the battery terminal).
    • The wiring or connector is damaged (check the circuit with a multimeter).
    • The drive disc is faulty (the teeth are worn or bent).
    • The ABS unit has failed (diagnostics required).
    Which ABS sensor is better to choose for Almera Classic - original or analogue?

    If your budget allows, it's better to take original (Nissan 40520-4M000/4M001). It will last longer and is guaranteed to fit. The most reliable of the analogues are Febi 21961 And TRW GSA11006. Cheap sensors (eg. Meyle) can work for only 1–2 years.

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

    Sometimes yes. If the problem is pollution or oxidation of contacts, cleaning may help. Remove the sensor, wipe it and the connector with alcohol or WD-40, check the resistance. If the sensor is physically damaged (cracks, broken wire), cleaning will not help - only replacement.

    Where is the ABS unit located on Nissan Almera Classic?

    The ABS unit is located under the hood, driver's side, next to the vacuum brake booster. It is shaped like a rectangular block with several connectors and brake pipes. To access it you need to remove the air duct and battery pad.
