Nissan Almera - one of the most popular foreign cars on the Russian market, especially in generations N16 (2000–2006), G15 (2012–2018) and G11 (2019–present). Among the typical problems, owners often encounter malfunctions reverse sensor — a small but critical element responsible for turning on the lights and camera when moving backwards. Its failure not only creates inconvenience, but also increases the risk of an accident due to the lack of signaling to other road users.
In this article we will look at how diagnose the reverse sensor Nissan Almera, what signs indicate its breakdown, how to check it with a multimeter and replace it yourself. We will also consider the nuances of selecting analogues, connection diagrams and common mistakes during repairs. The information is relevant for petrol and diesel versions with manual and automatic transmission.
Symptoms of a faulty reverse sensor
The first signal about problems with the sensor is lack of reaction from the car when reverse gear is engaged. However, symptoms may vary depending on the model and year of manufacture. Almera:
- 🚨 The reversing lights do not light up, although the lamps are working properly.
- 📹 The rear view camera is not activated (on models with multimedia NissanConnect).
- 🔊 An error appears on the dashboard (for example,
P0705— sensor circuit malfunction). - 🔧 Reverse gear engages with a crunch or difficulty (an indirect sign associated with mechanical wear).
On Almera G15 (2012–2018) with automatic transmission, a faulty sensor may block the mode from being activated R until the car comes to a complete stop. On manual transmissions, the problem most often manifests itself in the form of a lack of signal to the lights.
⚠️ Attention: If on Almera N16 The reverse lights stopped working after replacing the bulbs, check the fuse first F10 (10A) in the block under the steering wheel. Its burnout is a common cause of false positives.
In rare cases, the sensor may give false signal, due to which the lights are constantly on or the camera turns on randomly. This is due to oxidation of contacts or internal short circuit.

Where is the reverse sensor located on Nissan Almera
The location of the sensor depends on the type of gearbox and the generation of the vehicle. General rule: it is always installed on the gearbox housing and is triggered when the lever is moved to position R.
| Model | Gearbox type | Location | Original article number |
|---|---|---|---|
| Almera N16 (2000–2006) | Manual transmission | Left side of the gearbox, next to the speedometer drive | 39210-4M000 |
| Almera G15 (2012–2018) | Automatic transmission | Top of the box, under the air duct | 39210-3M60A |
| Almera G11 (2019–present) | CVT | Rear part of the variator, under protection | 39210-4M010 |
On Almera Classic (in some markets - Nissan Sunny) the sensor can be hidden under the plastic gearbox cover. To gain access you will need to remove the air duct and disconnect the connector E2 (for manual transmission) or E4 (on automatic transmission).
Visually the sensor looks as a cylindrical element with a 2-3 pin connector. On manual transmissions it is often combined with speed sensor, so when replacing it is important not to mix up the wires.
How to distinguish a reverse sensor from a speed sensor?
On Almera N16 The speed sensor has 3 contacts and is located above. Reverse sensor - with 2 contacts and smaller diameter. On G15/G11 they are separated and labeled with letters A (speed) and R (reverse).
How to check the reverse sensor with a multimeter
Diagnostics of the sensor takes 10–15 minutes and requires a minimum set of tools: a multimeter, a screwdriver and a jack (or inspection hole). Procedure:
- Remove the connector from the sensor. On Almera G15 To do this, press the latch and pull it up.
- Switch the multimeter into resistance test mode (ohmmeter).
- Connect the probes to the sensor contacts. On a working device, the resistance should be:
- 🔌 0 ohm — with the rod pressed (simulation of engaging reverse gear).
- 🔌 ∞ (infinity) - in the starting position.
+ there must be 12 V.If the resistance does not change or there is no voltage at the connector, the sensor is faulty. It is also worth checking the integrity of the wiring from the sensor to the body control unit (BCM).
☑️ Diagnosis of reverse sensor
⚠️ Attention: On Almera G11 with a variator, the reverse sensor is integrated into the gearbox control unit. Checking it requires a diagnostic scanner (for example, Launch X431) to read errors according to the protocol CAN.
Step-by-step instructions for replacing the sensor
Replacing the sensor with Nissan Almera does not require special skills, but there are nuances depending on the type of gearbox. Below are universal instructions for manual and automatic transmissions:
Required tools:
- 🔧 10 mm socket or wrench.
- 🔧 Screwdriver with a flat tip.
- 🔧 WD-40 (for soured threaded connections).
- 🔧 New sensor (original or analogue).
Work order:
- Turn off the power to the carby removing the negative terminal from the battery.
- Jack up the car or use a viewing hole. On Almera G15 It may be necessary to remove the crankcase protection.
- Clean the sensor from dirt and disconnect the connector. On an automatic transmission, first remove the air duct.
- Unscrew the sensor counterclockwise. On N16 It may be tight - do not use excessive force to avoid breaking the gearbox housing.
- Install a new sensor, having previously applied a sealant to the threads (for example, Loctite 577).
- Connect the connector and check the operation of the reversing lights.
On Almera G11 may be required after replacement reset variator adaptations through a diagnostic scanner. Without this procedure, jerks may occur when switching to R.
Before installing a new sensor, coat its O-ring with a thin layer of Litol-24. This will prevent moisture from entering and prolong service life.
Sensor selection: original vs analogues
Original sensors from Nissan reliable, but often overpriced. The table below shows proven analogues and their average cost for 2026:
| Manufacturer | Article | Compatibility | Price, ₽ |
|---|---|---|---|
| Original (Nissan) | 39210-4M000 (N16) | Manual transmission, 2000–2006 | 2 500–3 200 |
| Febi | 22316 | G15, automatic transmission | 1 200–1 500 |
| Blue Print | ADG02301 | G11, variator | 1 800–2 100 |
| Sasic | 4002100 | N16, universal | 800–1 000 |
On Almera G15 with automatic transmission sensors from Renault Logan (article 7701207827) are fully compatible in terms of connector and characteristics, but cost 2 times less than the original.
When choosing an analogue, pay attention to:
- 🔌 Number of contacts (2 or 3).
- 📏 Rod length (per N16 it's shorter than G15).
- 🔧 Case material (plastic or metal).
⚠️ Attention: Sensors for diesel Almera (for example, with an engine K9K) have a different resistance range. Installing them on gasoline versions will lead to incorrect operation of the lights.
Common replacement mistakes and how to avoid them
Even experienced car owners make mistakes when working with the reverse sensor. Here are the most common:
- ❌ Reversed polarity when connecting the connector. On Almera N16 this causes the fuse to blow
F10. - ❌ Insufficient tightening sensor Leads to oil leakage from the gearbox and a short circuit.
- ❌ Using silicone based sealant. It corrodes plastic connectors.
- ❌ Checking without removing the connector. The contacts may oxidize, which will give false readings on the multimeter.
On Almera G11 common mistake - replacing the sensor without resetting the variator adaptations. This results in an error P0705 and blocking reverse gear. To reset you need a scanner with support Nissan Consult.
After replacing the sensor on an automatic transmission or variator, be sure to check the oil level in the gearbox. Its leakage through a leaky sensor is one of the reasons for box failure.
FAQ: Frequently asked questions about the reverse sensor
Is it possible to drive without a reverse sensor?
Technically yes, but this unsafe. Without the lights on, other drivers won't realize you're reversing. On Almera G15 With automatic transmission, long-term driving without a sensor can lead to errors in the control unit.
Why do the lights stay on constantly after replacing the sensor?
This indicates contact closure inside the sensor or in the wiring. Check the resistance in the initial position with a multimeter - it should be infinite. If the problem persists, inspect the wiring harness for short circuits.
What sealant should I use during installation?
Recommended anaerobic sealants (For example, Loctite 577 or Permatex 59214). They do not harden in the air and do not spoil the carving. Silicone sealants cannot be used!
Is it possible to repair the reverse sensor?
In 90% of cases the sensor beyond repair, since its body is sealed. The exception is contact oxidation, which can be eliminated by cleaning with alcohol. If the internal mechanism is broken, only replacement.
Where can I buy a sensor for Almera cheaper?
The lowest prices are for AliExpress (but there is a risk of running into a fake) or in stores like AutoDoc, Ekat. It is cheaper to buy originals from official dealers during promotions (for example, in the fall of 2026 Nissan offered discounts of up to 20% on spare parts).
