Nissan Error P0720: Vehicle Speed Sensor Malfunction

Fault code P0720 on cars Nissan - one of the most common problems associated with the operation of transmissions and electronic systems. This error indicates a problem in the circuit Output Shaft Speed Sensor (OSS), which is responsible for the correct transmission of speed data to the control unit. Without accurate readings from this sensor, the car's electronic brain cannot properly regulate gear shifting, cruise control, or even the speedometer.

Owners Nissan Qashqai, X-Trail, Juke and other models often encounter this error after 100–150 thousand kilometers, but it can appear earlier - for example, after unqualified repairs or exposure to external factors (moisture, mechanical damage). In this article we will look at unique causes of P0720 specifically on Nissan, different from the general recommendations for other brands, and we will also give step-by-step instructions for diagnostics and repairs, taking into account the design features of Japanese cars.

What does error P0720 mean on Nissan: interpretation and consequences

Code P0720 in the diagnostic system OBD-II stands for Output Speed Sensor Circuit Malfunction - Malfunction of the output shaft speed sensor circuit. Unlike the error P0500 (vehicle speed sensor malfunction), which is related to the speedometer readings, P0720 directly affects the operation of the transmission:

• 🔄 Jerks when shifting gears — The automatic transmission may hesitate or jerk sharply when accelerating.
• ⚠️ Transmission emergency mode — the box goes into “limp mode” (rev limit and fixed gear).
• 📉 Unstable speedometer readings — the arrow jumps or freezes at zero.
• 🚫 Cruise control failure — the system simply does not activate.

By car Nissan with CVTs (CVT) error P0720 is especially dangerous: it can lead to overheating of the belt and accelerated wear of the box. For example, on Nissan Juke (J10) And Qashqai (J11) Ignoring this malfunction often ends in a major overhaul of the variator costing from 150 thousand rubles.

⚠️ Attention: If the error P0720 accompanied by a flashing indicator CHECK TRANSMISSION on the dashboard, operating the car strictly prohibited. This may indicate a critical malfunction of the automatic transmission or variator, requiring immediate towing to a service center.

The main causes of error P0720 on Nissan

In 70% of cases, the culprit of the error is oneself Output Shaft Speed Sensor (OSS), but there are other “pitfalls” characteristic of Nissan. Here is a complete list of possible reasons:

Feature Nissan — location of the OSS sensor. It is installed on most models on the gearbox housing on the right drive shaft side (if you look in the direction of travel). Because of this, the sensor often suffers from oil, dirt or mechanical damage when replacing CV joints. For example, on Nissan Almera G15 And Sentra B17 The sensor is secured with only one bolt, which increases the risk of it moving due to vibration.

How to diagnose the P0720 code yourself

Before going to the service center, you can carry out preliminary diagnostics on your own. You will need:

• 🔧 Multimeter (with resistance and voltage testing mode).
• 🔍 Flashlight and mirror on a telescopic handle (for inspecting the sensor).
• 📱 Diagnostic scanner (for example, ELM327 with the program Torque Pro).

Step 1. Checking for errors with a scanner

Connect the scanner to the connector OBD-II (located under the steering wheel, to the left of the pedals on most models Nissan). Except P0720 Please note the accompanying codes:

• P0715 — malfunction of the input shaft speed sensor (ISS).
• P0730 — incorrect transmission ratio.
• U1000 — loss of communication with the control unit (TCM).

Step 2: Visual inspection of the OSS sensor

On most models Nissan The sensor is located next to the right CV joint. Access algorithm:

1. Raise the car on a lift or jack (be sure to secure it!).
2. Remove the crankcase protection (if equipped).
3. Find the sensor - it looks like a cylinder with a wire screwed into the automatic transmission housing.
4. Check the integrity of the wiring and connector (for oxidation, breaks).

Step 3. Test with a multimeter

Disconnect the sensor connector and measure the resistance between the contacts. Normal values for Nissan:

• 🔹 800–1400 Ohm - for most models with automatic transmission.
• 🔹 1000–1800 Ohm — for variators (CVT).

If resistance 0 ohm (short circuit) or ∞ (break), the sensor must be replaced. Also check the voltage at the connector with the ignition on - it should be 5 V.

Step-by-step instructions for replacing the OSS sensor on a Nissan

If diagnostics confirm that the sensor is faulty, you can replace it yourself. Difficulty of the procedure - 3 out of 5 (requires accuracy and basic repair skills). Below are instructions for most models Nissan with automatic transmission/variator.

Required tools:

• 🔧 10 mm socket (for sensor mounting bolt).
• 🔧 Extension and ratchet handle.
• 🧲 Magnet (to remove the bolt if it falls).
• 🧴Sealant Loctite 574 (for the thread of the new sensor).

Sequence of actions:

1. Disconnect the negative terminal of the battery (to avoid short circuit).
2. Raise the car and remove the engine protection (if it interferes with access).
3. Disconnect the OSS sensor connector. On some models (for example, Nissan X-Trail T32) the connector is fixed with a plastic latch - press it with a screwdriver.
4. Unscrew the sensor mounting bolt (usually M6). Attention: the bolt may be stuck - do not use excessive force to avoid stripping the thread.
5. Carefully remove the sensor. In its place you will see a magnetic ring - check it for metal shavings.
6. Install the new sensor by first applying sealant to the bolt threads. Tighten firmly 8–10 Nm.
7. Connect the connector and return the protection to its place.

After replacement be sure to clear errors through a scanner. If the code P0720 appears again, the problem may lie in the wiring or control unit (TCM).

Cost of repairs and selection of spare parts

The cost of solving the problem depends on the cause and model of the car. Below are approximate prices for Nissan in Russia (for 2026):

Tips for choosing a sensor:

• 🔍 For CVTs (CVT) take only the original or proven analogues (Febi or Meat & Doria). Cheap sensors often give false signals.
• 📦 When purchasing, check that the O-ring is included. On some models (for example, Nissan Teana J32) it is sold separately.
• 🔧 On cars older than 2010 (for example, Nissan Primera P12) it may be necessary to replace the sensor connector - over time, the contacts oxidize.

⚠️ Attention: On models with a CVT (Nissan Juke, Qashqai, X-Trail) after replacing the OSS sensor, it is necessary to reset the box adaptations through the diagnostic scanner. Without this, the error may return after 100–200 km. Services charge for this procedure 500–1 500 ₽.

Prevention of error P0720: how to avoid repeated problems

To make a mistake P0720 did not return, follow these recommendations:

• 🛡️ Check the oil level in the automatic transmission/variator regularly. On Nissan with CVT oil needs to be changed every 60,000 km (despite the dealer's claims of a "maintenance free" box).
• 🔧 Avoid aggressive driving. Sudden starts and braking accelerate wear of the magnetic ring on the shaft.
• 🚿 Wash the automatic transmission housing from dirt. If sand or salt gets on the sensor connector, it can cause corrosion of the contacts.
• 🔌 Check the wiring. On Nissan Pathfinder R51 And Murano Z51 The wiring harness often rubs against the suspension bracket.

If your Nissan is used in off-road conditions or often drives through puddles, install additional protection on the OSS sensor. For example, on Nissan Navara D40 And NP300 You can use a silicone case for the connector (article no. 39398-4M000).
