Outside air temperature sensor (ETNV) on Nissan Qashqai - a small but critical element that affects the operation of the climate system, the display of data on the on-board computer and even fuel consumption. Many owners are faced with the fact that the temperature readings on the dashboard begin to “lie”: in summer they show -10°C, and in winter +20°C. This is not just an annoying detail - incorrect data can lead to malfunctions automatic climate control, incorrect operation of fans or even activation of emergency modes.
In this article we will look at where the sensor is located on Qashqai J10 (2007–2013) and J11 (2014–2021), how to check it with a multimeter, what errors it produces in the OBD-II system, and we will give step-by-step instructions for replacement with photos and videos. You will also learn why, after replacing the sensor, the temperature may still be displayed incorrectly - and how to fix it without contacting service.
Where is the outside air temperature sensor located on a Nissan Qashqai?
The location of the DTNV depends on the generation of the crossover:
- 🔹 Qashqai J10 (2007–2013): The sensor is installed behind the front bumper, on the driver's side, next to the fog lamp. To get to it, you will have to remove part of the plastic side member or dismantle the bumper.
- 🔹 Qashqai J11 (2014–2021): the sensor was moved closer to the radiator, behind the decorative grille. Here it is less protected from dirt and moisture, so it fails more often.
- 🔹 Qashqai J12 (2021–present): The sensor is integrated into the headlight control module (BCM), it cannot be replaced separately - only the entire module.
On J10 And J11 The sensor is a small plastic cylinder with a 2-pin connector. It is attached to the body with one screw or latch. The main problem is access: on J10 the bumper is in the way J11 — a radiator grille that will have to be removed.
⚠️ Attention: Do not confuse DTNV with interior temperature sensor (located under the dashboard) or coolant temperature sensor (in the engine block). They perform different functions and are not interchangeable.

Signs of a malfunctioning outside air temperature sensor
The main symptom is Incorrect temperature readings on the on-board computer display. But there are other “bells and whistles”:
- 🌡️ The temperature is “frozen” at one value (for example, it always shows -40°C or +50°C).
- ❄️ Climate control does not work adequately: cold air blows in winter, warm air blows in summer.
- ⚠️ Lights up on the dashboard
CHECK ENGINEor errorU1000(loss of connection with the sensor). - 🔄 After starting the engine, the temperature on the display changes abruptly (for example, from +20°C to -10°C per second).
- 💨 Cooling system fans turn on for no reason or do not turn off.
On Qashqai J11 with the system NissanConnect A faulty sensor can block the autostart or remote climate control functions via the application. Also, some owners complain that if the DTNV breaks down, it stops working automatic switching of headlights (if it is connected with light sensors).
⚠️ Attention: If the temperature on the display shows -40°C, this almost always means an open circuit in the sensor. If the readings “float” within the range of ±20°C from the real ones, the problem may be oxidation of the contacts or damage to the wiring.
How to check the outside air temperature sensor with a multimeter
Before replacing the sensor, it must be checked. To do this, you will need a multimeter with a resistance measurement function (ohmmeter). Algorithm of actions:
- Remove the sensor from the car (instructions below).
- Connect the multimeter probes to the sensor contacts (polarity is not important).
- Place the sensor in a container of water and gradually change its temperature (you can use a thermometer to control).
- Compare resistance readings with reference values (see table below).
| Temperature, °C | Resistance, kOhm (nominal) | Permissible deviation |
|---|---|---|
| -20 | 14.1–16.8 | ±10% |
| 0 | 5.2–6.0 | ±8% |
| +20 | 2.3–2.7 | ±7% |
| +40 | 1.1–1.3 | ±5% |
If the resistance does not change with temperature changes or is very different from the nominal value, the sensor is faulty. Also check the circuit for an open circuit: the resistance between the connector contacts on the machine (with the sensor disconnected) should be close to 0 Ohm.

Step-by-step instructions for replacing the sensor on Nissan Qashqai J10 and J11
To replace you will need:
- 🔧 Set of screwdrivers (phillips, flat).
- 🔨 Plastic clips for removing body kits (if you remove the bumper).
- 🧴 WD-40 or similar lubricant (for rusty fasteners).
- 🔌 New sensor (see article numbers below).
Article numbers of original sensors:
- 📌 Qashqai J10:
25560-4M00Aor25560-4M00B. - 📌 Qashqai J11:
25560-4M20A(until 2017) or25560-4M20B(after 2017). - 📌 Analogues: Febi 37726, Blue Print ADT34108, Valeo 726501.
Instructions for Qashqai J10:
- Remove the left plastic side member (unscrew the 3 screws and 2 clips).
- Disconnect the sensor connector by pressing the latch.
- Unscrew the screw securing the sensor (may be under Torx T20).
- Install the new sensor in reverse order.
Instructions for Qashqai J11:
- Remove the decorative radiator grille (snap off the 4 clips on top and 2 on the bottom).
- Disconnect the sensor connector (it can be glued to the body with double-sided tape).
- Rotate the sensor counterclockwise and remove it from its socket.
- Install the new sensor, making sure the O-ring is in place.
⚠️ Attention: On J11 after replacing the sensor it may be necessary error reset via a diagnostic scanner (for example, Launch X431 or Delphi). If the error U1000 remains - check the circuit for a short circuit.
Before installing a new sensor, apply dielectric grease to its contacts - this will protect them from oxidation and extend their service life.
OBD-II Errors Related to Outside Air Temperature Sensor
A faulty DTNV can cause the following errors in the self-diagnosis system:
| Error code | Description | Possible reason |
|---|---|---|
P0070 |
Outside air temperature sensor circuit | Broken wire or corroded contacts |
P0071 |
Incorrect sensor signal | Sensor damage or short to ground |
P0072 |
Low sensor signal level | Short circuit to ground |
P0073 |
High sensor signal level | Short circuit to +12V or open circuit |
U1000 |
Loss of communication with the module | CAN bus problems or BCM malfunction |
On Qashqai J11 with the system NissanConnect error U1000 may appear not only due to the sensor, but also due to malfunctions in the body control unit (BCM). In this case, an in-depth diagnosis is required.
⚠️ Attention: If the error does not clear after replacing the sensor, check fuse F37 (10A) in the mounting block - it is responsible for powering the sensor circuit.
What to do if after replacing the sensor the temperature is still incorrect
If a new sensor is installed, but the temperature on the display still “lies,” the reasons may be the following:
- 🔌 Oxidation of contacts in the connector: Even if the sensor is new, poor contact in the block will lead to failures. Clean the contacts with alcohol or a special liquid.
- 📶 Interference on the CAN bus: on J11 The sensor transmits data via a digital bus. If there are problems with the wiring or unit BCM, the readings will be incorrect.
- 🔄 Need for calibration: on some versions Qashqai After replacing the sensor, adaptations must be reset via diagnostic equipment.
- 🌡️ The sensor is not original: Cheap analogues (especially unnamed Chinese ones) may give inaccurate readings. Check the resistance of the new sensor before installation.
🔹 How to check the CAN bus?
To do this, you will need an oscilloscope or scanner with bus diagnostic support. Normal voltage at CAN-H And CAN-L should be about 2.5V (the difference between the lines is 2B). If there is no voltage or is very different, the problem is in the wiring or unit BCM.
How to reset sensor adaptations without a scanner?
On some versions of Qashqai J11 the following method helps:
1. Disconnect the battery terminal for 10 minutes.
2. Plug it back in and start the engine.
3. Let the car idle for 5-7 minutes - during this time the BCM will reboot and “pick up” the new sensor.
⚠️ The method does not work on all software versions!
Cost of the sensor and replacement work in 2026
Prices for sensors and work vary depending on the region and service:
| Position | Price, ₽ | Notes |
|---|---|---|
| Original sensor (Nissan) | 1 800–2 500 | Articles 25560-4M00A, 25560-4M20A |
| Analogue (Febi, Blue Print) | 800–1 500 | Quality comparable to the original |
| Chinese sensor (no-name) | 300–600 | Often lies at ±5°C, not recommended |
| Replacing the sensor (service) | 1 000–2 000 | Includes diagnostics and error reset |
| Self-replacement | 0 (if there is a tool) | Takes 30–60 minutes |
💡 Advice: If you buy a disassembled sensor, be sure to check its resistance with a multimeter. Many “used” sensors are already worn out and give incorrect readings.
Saving on a sensor can result in problems with climate control and increased fuel consumption. The original sensor or a high-quality analogue (Febi, Valeo) will last longer and will not require frequent replacement.
FAQ: Frequently asked questions about the temperature sensor on Nissan Qashqai
Is it possible to drive with a faulty outside air temperature sensor?
Yes, the car will drive, but the climate control may not work correctly (for example, cold air will blow in winter, and warm air in summer). False activations of cooling fans are also possible. On Qashqai J11 with NissanConnect Autorun functions may fail.
Why did the sensor start to lie after washing?
Most likely, water got into the sensor connector, which led to oxidation of the contacts. Remove the connector, dry it and treat the contacts WD-40 Contact Cleaner or similar means. If the problem persists, check the sensor with a multimeter.
Which sensor is better to buy: original or analogue?
Original sensor (25560-4M20A for J11) is guaranteed to last longer, but costs 2 times more than analogues. From non-original we recommend Febi 37726 or Blue Print ADT34108 - they are close in quality to the original. Cheap Chinese sensors (for 300–500 ₽) often lie by 3–5°C.
Do I need to reset errors after replacing the sensor?
On Qashqai J10 usually not required - the error resets itself after 2-3 engine starts. On J11 a diagnostic scanner reset may be required (eg Launch CReader), especially if it's on U1000.
Is it possible to disable the outside air temperature sensor?
You can physically disable it, but this will lead to a permanent error P0070 and incorrect operation of climate control. Some owners Qashqai J11 disable the sensor programmatically via firmware BCM, but this requires deep knowledge in chip tuning.
