Error code P1700 on Nissan Teana J32: complete analysis of the problem

Error P1700 on Nissan Teana J32 (2008–2013) is one of the most common transmission malfunctions encountered by owners of this business sedan. It signals problems at work automatic transmission (automatic transmission), but its causes can vary from a banal low oil level to serious breakdowns of the mechatronics or valve body. Unlike other errors, P1700 on Teana J32 often appears during sudden temperature changes or after prolonged parking, which complicates diagnosis without specialized equipment.

In this article we will analyze in detail what the code means P1700, what symptoms accompany it, and - most importantly - how to fix the problem on your own or at minimal cost. You will learn what tools you will need for diagnostics, which parts most often fail, and when you should contact service and when you can do the repairs yourself. We will pay special attention specifics of Teana J32, since on other Nissan models (for example, Maxima or Altima) this error may have other causes.

What does error P1700 mean on Nissan Teana J32?

Code P1700 in the diagnostic system Nissan stands for "Transmission control circuit malfunction" (Transmission Control System Malfunction). This is a general code that indicates an electrical or hydraulic problem. Automatic transmission, but does not specify it. On Teana J32 with box RE0F10A (or its modifications) the error is most often associated with:

• 🔋 Low or contaminated transmission fluid (especially if the oil has not been changed for more than 60,000 km).
• 🔌 Malfunction of solenoids in the valve body responsible for gear shifting.
• 📶 Problems with wiring or connectors between the automatic transmission control unit (TCM) and a box.
• 🛠️ Mechanical wear friction discs or bearings.

It is important to understand that P1700 - this is not a sentence, but a signal to action. In the early stages, the problem can be solved by simply changing the oil or cleaning the contacts, but if the error is ignored, it will lead to automatic transmission emergency mode (the box “goes into neutral” or is blocked in one gear) and expensive repairs.

⚠️ Attention: On Teana J32 with engines VQ25DE And VQ35DE error P1700 sometimes appears after changing the oil in the automatic transmission, if non-original or low-quality oil was filled. In this case, a complete flushing of the system is required.

Symptoms of error P1700: how to recognize the problem?

Error P1700 rarely appears “on its own” - it is usually accompanied by noticeable changes in the behavior of the car. Here are the key signs to look out for:

• 🚗 Jerks or delays when shifting gears (especially from 1st to 2nd or from 3rd to 4th).
• 🔄 Spontaneous switching to emergency mode (the “AT” or “Check Engine” icon lights up on the dashboard).
• 🛑 Difficulty starting from a standstill — the car “slips” or jerks when starting off.
• 📉 Power Loss at high speeds (the gearbox “does not pull” or “skips” gears).

On Teana J32 error P1700 often appears in cold weather or after long periods of parking. For example, in the morning after parking overnight, the box may work unstably for the first 5–10 minutes, and then “return to normal.” This is a typical symptom contaminated oil or wear of solenoids.

If you notice any of these symptoms, do not delay diagnosis. The longer you drive with an error P1700, the higher the risk of damage torque converter or planetary gear, which will result in repairs costing 100,000+ rubles.

Reasons for error P1700 on Teana J32

On Nissan Teana J32 error P1700 may arise for several reasons, and they can be divided into electric, hydraulic And mechanical. Let's look at each group in more detail.

1. Electrical reasons

Problems with wiring or control units are one of the most insidious causes, since they are difficult to diagnose without a scanner. Most often the culprits are:

• 🔌 Oxidation of contacts on the connector of the automatic transmission control unit (TCM).
• 📡 Broken or shorted wires between TCM and a box.
• 🔋 Malfunction of the unit itself TCM (less common, but requires replacement).

2. Hydraulic reasons

Associated with the operation of oil and solenoids. On Teana J32 This is the most common group of problems:

• 🛢️ Low level or old oil in automatic transmission (recommended replacement interval is every 60,000 km).
• 🔧 Valve block contamination wear products (metal shavings, friction dust).
• 🔩 Solenoid malfunction (most often solenoids fail SL1 And SL2).

3. Mechanical reasons

The most serious and expensive to repair. Include:

• ⚙️ Friction disc wear (especially if the oil has not been changed for a long time).
• 🔄 Bearing failure planetary gear set or torque converter.
• 🛠️ Shaft deformation or gears in a box.

In practice, in 70% of cases there is an error P1700 on Teana J32 associated with oil or solenoids. Mechanical breakdowns are less common, but their consequences are much more serious.

Reason	Frequency of occurrence	Remediation cost (approx.)
Contaminated automatic transmission oil	60%	5,000–10,000 ₽ (oil change + filter)
Faulty solenoids	25%	15,000–30,000 ₽ (replacement of solenoids or valve body)
Wiring/TCM problems	10%	3,000–20,000 ₽ (cleaning contacts or replacing TCM)
Mechanical wear of automatic transmission	5%	50,000–150,000 ₽ (overhaul or replacement of the box)

Diagnosing error P1700: step-by-step instructions

To pinpoint the cause P1700, a comprehensive diagnosis will be required. Below is a step-by-step action plan that you can do yourself or with the help of a car service.

1. Reading error codes

The first step is to connect a diagnostic scanner (for example, Launch CReader or ELM327) and read all saved errors. On Teana J32 along with P1700 often appear:

• P0730 - incorrect gear ratio.
• P0740 — faulty torque converter locking.
• P0750 - problem with solenoid SL1.

If there are several errors, this narrows the search. For example, P0750 + P1700 are almost guaranteed to indicate a faulty solenoid.

2. Checking the level and condition of the automatic transmission oil

On Teana J32 The oil level is checked at hot box (after 10–15 minutes of driving) with the engine running. Algorithm:

1. Place the machine on a level surface.
2. Switch the automatic transmission selector through all positions, holding each position for 2–3 seconds.
3. Pull out the automatic transmission dipstick (located to the right of the engine, under the air duct), wipe it and lower it again.
4. Check the level: it should be between the marks HOT MIN And HOT MAX.

Also rate oil color and smell:

• 🟢 Light red or pink — oil is normal.
• 🟤 Brown or dark - replacement required.
• ⚫ Black with a burning smell — critical condition, urgent replacement + diagnostics of the box is needed.

3. Checking wiring and connectors

Inspect the connectors on the automatic transmission control unit (TCM) and box. On Teana J32 TCM located under the center console, next to the gearshift lever. Signs of problems:

• 🔌 Oxidation or green plaque on contacts.
• 🔥 Melted or burnt wires.
• 🛠️ Poorly fixed connectors (may come off due to vibration).

4. Test drive with recording of symptoms

Drive the car, paying attention to:

• 🚦 Moments when jerks appear (during acceleration, braking, switching).
• 🔄 The reaction of the box to switching to manual mode (M/+–).
• 🛑 The behavior of the car when stopping (for example, if it “twitches” at a traffic light).

⚠️ Attention: If, when driving at speeds above 60 km/h, the transmission suddenly goes into emergency mode ("AT" lights up), stop immediately and do not continue driving. This may indicate critical torque converter malfunction or loss of oil pressure in automatic transmission.

How to fix error P1700: repair methods

Remedy P1700 depends on the reason. Below are step-by-step instructions for the most common cases.

1. Changing the automatic transmission oil

If the oil is dirty or its level is below normal, a complete replacement will be required. On Teana J32 this can be done in two ways:

• 🔄 Partial replacement (drain through the plug) - suitable if the oil is not very dirty. Requires ~4 liters of oil Nissan Matic S.
• 🔃 Complete replacement with flushing (through the machine) - required if the oil is black or smells like burning. You will need ~10–12 liters of oil.

Partial replacement algorithm:

1. Warm up the box (drive 10–15 km).
2. Raise the car on a lift or pit.
3. Unscrew the drain plug on the automatic transmission pan and drain the oil.
4. Remove the pan, clean it and replace the filter (catalog number: 31726-31X01).
5. Reinstall the pan, tighten the plug with a new gasket (11026-01M02).
6. Fill in new oil through the dipstick hole (the level is between HOT MIN And HOT MAX).

2. Cleaning or replacing solenoids

If the diagnostics showed a malfunction of the solenoids (for example, an error P0750), you can try to clean or replace them. On Teana J32 solenoids are in valve body, which is located inside the box.

For cleaning:

1. Remove the automatic transmission pan and drain the oil.
2. Unscrew the valve body (you will need a torx T30).
3. Remove the solenoids, wash them in carburetor cleaner and blow them with compressed air.
4. Check the resistance of the solenoids with a multimeter (normal: 10–15 ohms).
5. Reinstall the solenoids, reassemble the box and fill with new oil.

If the solenoids are faulty, they will have to be replaced. The price of a new set is about 10,000–15,000 rubles.

3. Repair or replace TCM

If the problem is in the control unit (TCM), you can try to repair it (resolder the contacts) or replace it. On Teana J32 TCM costs about 20,000–30,000 ₽ new, but cleaning the contacts or flashing the firmware often helps.

4. Overhaul of automatic transmission

If the error P1700 caused by mechanical wear (for example, burnt clutches or broken bearings), the box will need to be disassembled. Average cost of major repairs Teana J32 — 50 000–100 000 ₽.

What happens if you ignore P1700?

Driving for a long time with this error leads to overheating of the automatic transmission, accelerated wear of the clutches and, ultimately, to jamming of the box. In the most severe cases, it may be necessary to replace the automatic transmission assembly (cost - from 150,000 rubles).

Prevention of error P1700 on Nissan Teana J32

To avoid reappearance P1700, follow these guidelines:

• 🛢️ Change the automatic transmission oil every 60,000 km (or once every 4 years if the mileage is low). Use only original oil Nissan Matic S.
• 🔧 Check the oil level every 10,000 km (especially before long trips).
• 🚗 Avoid aggressive driving (sharp starts, towing heavy loads).
• 🔌 Clean TCM contacts regularly from oxidation (every 2–3 years).
• ❄️ Warm up the box in winter before starting to move (let the engine run for 2–3 minutes with the brake pedal pressed and the mode turned on D).

It is also useful to carry out once a year computer diagnostics Automatic transmission, even if there are no errors. This will help identify hidden problems at an early stage.

Frequently asked questions (FAQ)

Is it possible to drive with P1700?

Short term - yes, but not recommended. Driving for a long time with this error leads to accelerated wear of the automatic transmission. If the transmission works stably (no jerking or loss of power), you can drive to the service center, but no more than 100–200 km. If symptoms of emergency mode appear ("AT" lights up), it is better to stop driving and call a tow truck.
