Error P0705 on Nissan: decoding, diagnostics and repair

Error P0705 on the dashboard Nissan - a signal about problems in the transmission that cannot be ignored. This code indicates a fault in the circuit selector lever position sensor (TR sensor), which can lead to unpredictable behavior of the gearbox: from difficult shifting to complete failure of the automatic transmission. Owners Qashqai, X-Trail, Juke and other models with automatic transmission encounter this error most often after 100–150 thousand kilometers, but the reasons can be different - from banal oxidation of contacts to failure of the sensor itself.

In this article we will look in detail at what it means code P0705 specific for Nissan vehicles, how to correctly diagnose it (including nuances for different models), and what steps to take to fix it - from a simple wiring check to replacing the sensor. We will pay special attention to typical repair mistakes that can aggravate the problem, and provide a checklist for self-diagnosis.

What does error P0705 mean on Nissan?

Code P0705 in the self-diagnosis system Nissan stands for "Range Sensor Circuit Malfunction (PRNDL Input)". Simply put, the transmission control module (TCM) is not receiving the correct signal from the shift lever position sensor that tells you what mode (P, R, N, D) there is a box. This is critical because:

• 🔴 Without an exact signal The TCM is unable to control the valve body and clutch correctly, resulting in jerking, shifting delays, or gear lock-up.
• ⚠️ False signals may make the box "think" that you have turned it on R instead of D, which is fraught with an accident when driving.
• 🛑 Ignoring the error leads to accelerated wear of automatic transmission clutches and solenoids, the repair of which will cost 50–150 thousand rubles.

On Nissan Qashqai J10/J11, X-Trail T31/T32 And Note E12 lever position sensor (aka inhibitor switch) is usually located on the automatic transmission housing next to the selector lever. On models with a CVT (Juke, Ariya) the operating principle is similar, but the sensor can be integrated into the CVT control unit.

⚠️ Attention: If error P0705 is accompanied by a flashing light AT or Check Engine, operate a car prohibited - this can lead to failure of the mechatronics or torque converter.

Reasons for error P0705

According to statistics from service centers, in 60% of cases it is not the sensor itself that is to blame, but problems with the wiring or contacts. Here is a complete list of possible causes, ranked by frequency:

Reason	Frequency (%)	Symptoms
Oxidation or broken sensor wiring	45%	The error appears periodically, especially in humid weather.
Faulty lever position sensor (TR sensor)	30%	Permanent error, the box “does not see” the position of the selector
Problems with body weight/automatic transmission	15%	Related errors on the CAN bus (U1000, P0607)
Mechanical wear or breakage of the selector lever	7%	Stiff shifting, lever play
TCM firmware failure	3%	The error appears after disconnecting the battery or firmware

On Nissan Almera N16 And Primera P12 with a 4-speed automatic transmission (RE4F03A), the sensor often fails due to oil getting into the connector. On CVTs Jatco JF011E/JF016E (installed on Qashqai, X-Trail) the problem may be related to incorrect operation of the selector lock solenoid.

Symptoms of error P0705: how the malfunction manifests itself

Error P0705 rarely comes “alone” - it is usually accompanied by noticeable changes in the behavior of the transmission. Here are the key signs to look out for:

• 🚗 The "Check Engine" light comes on and AT - the first signal of a problem. On some models (for example, Murano Z50) a message may be displayed "Transmission Hot" even at normal temperatures.
• 🔄 The box freezes in one mode - for example, does not switch from D on R or vice versa. CVTs may lose traction.
• ⚡ Jerks when shifting gears, especially when moving from N on D or R. On Nissan Teana J32 this is often accompanied by a shock to the transmission.
• 🔧 Can't start the car - some models (for example, Pathfinder R51) block engine starting in the event of a critical error in the selector sensor.

On vehicles with the system NissanConnect (For example, Ariya) the error may be duplicated in the mobile application with the code P0705-00. If codes appear along with P0705 P0730 (incorrect gear ratio) or P0700 (TCM open circuit), the problem is most likely in the control unit or the wiring between the sensor and the TCM.

⚠️ Attention: If after resetting the error by the scanner (for example, Launch X431 or ELM327) it returns immediately after starting the engine, the problem is 100% hardware - Checking the sensor and wiring is required.

Diagnosis of error P0705: step-by-step instructions

Before going to the service center, you can conduct preliminary diagnostics yourself. You will need a multimeter (or at least a test light) and access to the selector switch sensor. Here is the algorithm of actions:

We park the car on a flat surface, turn on the parking brake

Disconnect the negative terminal of the battery (wait 10 minutes for errors to clear)

We find the lever position sensor (usually on the automatic transmission housing under the air duct)

Visually check the connector for oxidation or damage -->

1. Checking the sensor connector:

   Disconnect the connector from the sensor and inspect the contacts. Oxidation (green coating) or burnt pins are a common cause of P0705. Clean the contacts with alcohol or a special liquid Contact Cleaner.

2. Wiring continuity:

   Set the multimeter to circuit test mode. Run the wires from the sensor to the TCM (usually located under the center console). The resistance should be close to 0 ohms. If the chain is broken, look for a break.

3. Checking the sensor power supply:

   Turn on the ignition (without starting the engine). The sensor connector should have +12V on one of the contacts (usually a red or orange wire). No power indicates a fuse or relay problem.

4. Sensor signal test:

   Connect a multimeter in voltmeter mode to the signal wire of the sensor (usually green or black). When switching the selector lever, the voltage should change in the range 0.5–4.5V. No change is a sign of a sensor malfunction.

On Nissan Navara D40 And NP300 with automatic transmission RL4R01A The selector sensor often fails due to dirt getting into the mechanical part. In this case, disassembling and cleaning the contact group will help.

How to resolve error P0705: from simple to complex

The repair method depends on the cause of the problem. Let's start with the simplest and cheapest solutions:

1. Cleaning contacts and connectors

In 40% of cases, error P0705 disappears after simply cleaning the contacts. Use:

• 🧴 Spray CRC Contact Cleaner — removes oxides and fatty deposits.
• 🧽 Toothbrush with stiff bristles — for mechanical cleaning of the connector.
• 🔌 Dielectric grease — after cleaning, apply to the contacts to protect them from moisture.

On Nissan Juke F15 with variator JF015E Reconnecting the TCM connector (located under the front passenger seat) often helps.

2. Replacing the lever position sensor

If the sensor is faulty, it must be replaced. The cost of the original sensor for Qashqai J11 — about 8–12 thousand rubles (item number 32515-4M000 or 32515-4M00A). Analogues from Febi or Blue Print will cost 3–5 thousand rubles.

Important: When replacing the sensor on CVTs Nissan may require adaptation using a diagnostic scanner (e.g. Consult-III+). Without this, the box will not work correctly.

3. Wiring repair

Breaks or shorts in the wiring harness are a common problem on cars older than 10 years. Please note:

• 🔍 Wires under the gas pedal - often fray.
• 🚗 Harness near the gearbox - may melt from heating.
• 💧 Connectors under the hood - corrosion due to water ingress.

How to check ground on Nissan?

Ground wires on Nissan are often attached to the body with bolts and washers. Inspect the points where the mass is attached to the automatic transmission (usually on the box body next to the pan) and to the body (under the battery or on the side member). Clean and tighten oxidized or loose bolts. On models with a CVT, check the weight of the TCM unit - it may be hidden under the plastic protection.

4. TCM firmware

In rare cases, error P0705 is caused by a software failure in the control unit. This is relevant for Nissan Leaf (electro) and Ariya with electronic selectors. For flashing you will need:

• 💻 Diagnostic scanner with support Nissan (For example, Launch X431 Pro).
• 📁 Original firmware file (can be found on the forums Nissan Club).
• ⚡ Stable power supply (it is better to connect the charger during the firmware installation).

⚠️ Attention: Incorrect TCM firmware can completely damage the unit. If you have no experience, entrust it to specialists.

Typical mistakes when repairing P0705

Many owners Nissan They make the problem worse by trying to save money or following “tips” from the Internet. That's what can't do:

• 🚫 Ignore related errors - if there are codes along with P0705 P0715 (input speed sensor) or P0720 (output speed sensor), the problem may be in the valve body and not in the selector lever sensor.
• 🔧 Install a used sensor - even if he is a “worker”, his resource may be running out. The original new sensor will last longer.
• 💡 Reset error without diagnostics - if you simply erase P0705 with a scanner, it will return, and the problem will get worse.
• 🔌 Use decoys for the sensor - This is a temporary solution that can lead to failure of the automatic transmission solenoids.

On Nissan X-Trail T32 with variator JF011E A common mistake is installing a sensor from a different model (for example, from Qashqai J10). This leads to signal incompatibility and new errors (P0705 + U1000).

1. The connector is connected correctly (do not mix up the pins!).

2. Wiring integrity from sensor to TCM.

3. Availability of power and ground on the control unit.-->

Prevention of error P0705

To avoid problems with the lever position sensor, follow these recommendations:

• 🛢️ Change the automatic transmission oil every 60 thousand km — contaminated oil accelerates sensor wear.
• 🚿 Avoid high-pressure engine washing — water gets into the connectors and causes corrosion.
• 🔧 Clean the sensor contacts periodically — it is enough to remove the connector once a year and wipe it with alcohol.
• 📊 Monitor the oil level in the automatic transmission - a low level leads to overheating and malfunction of the electronics.

On Nissan Qashqai J11 with variator JF016E It is recommended to check the condition of the wiring harness going from the selector to the TCM every 100 thousand km - it often rubs against the gas pedal bracket.

FAQ: Frequently asked questions about error P0705

Is it possible to drive with error P0705?

Short term - yes, but with caution. If the box shifts normally, you can go to the service center. However, if there are jerks, delays or inability to engage the gear operation prohibited - this can lead to damage to the automatic transmission.

How much does it cost to repair error P0705 in the service?

The cost depends on the reason:

• Cleaning contacts - 1–2 thousand rubles.
• Replacement of the sensor - 5–15 thousand rubles (including labor).
• Wiring repair - 3-10 thousand rubles.
• TCM firmware - 5-20 thousand rubles.

On the official service Nissan diagnostics will cost 2–3 thousand rubles.

Can error P0705 appear after replacing the battery?

Yes, it's possible. When the battery is disconnected, the adaptive settings of the TCM are reset, and if the selector sensor was already “on edge”, the control unit may begin to generate an error. In this case, resetting the adaptations through the scanner or disconnecting the terminal again for 10 minutes will help.

Where is the lever position sensor located on the Nissan Qashqai J11?

On Qashqai J11 (2013–2021) the sensor is located on the automatic transmission/variator housing, under the plastic selector housing. To get to it:

1. Remove the decorative trim around the lever.
2. Unscrew the casing bolts (usually 4 pieces).
3. The sensor will be visible to the right of the lever - it is secured with two bolts.

Is it possible to reset error P0705 without a scanner?

Yes, but this is a temporary solution. Disconnect the negative terminal of the battery for 10-15 minutes - this will clear errors in the TCM memory. However, if the problem persists, the code will return the next time the engine is started. To completely reset adaptations on CVTs Nissan need a scanner.
