Nissan Juke P0871: Transmission Fluid Pressure Sensor/Switch “C” Range/Performance


P0871 Nissan Juke

P0871 is a somewhat rare diagnostic trouble code. While your Nissan Juke’s check engine light comes on, this particular code indicates that there is something wrong with the transmission, specifically the transmission fluid pressure sensor switch “C.”

It is a generic code, so P0871 has the same definition for any vehicle manufactured after 1996. Before doing anything, check your Juke’s transmission fluid. Make sure it is full and does not appear burnt or discolored.

Abbreviations used in this article:

  • PCM– Powertrain control module, is the main computer module with engine and transmission control in a single unit
  • TCM– Transmission control module, the TCM controls transmission shifting and is separate from the engine control module. Your Nissan Juke will have a PCM or a TCM. And, for the purposes of this article, they are interchangeable.
  • TFPS– Transmission fluid pressure sensor

P0871 Definition: Transmission Fluid Pressure Sensor/Switch “C” Range/Performance

P0871 Definition Nissan Juke

Here is the definition of P0871 for the Nissan Juke broken down into its individual parts

Transmission fluid pressure sensor/switch

The TFPS has two main functions:

  1. Convert transmission fluid pressure into a signal that the PCM (or TCM) can use to control shifting.
  2. Verifies that the PCM/TCM transmission shift request has occurred.

Circuit “C” Range/performance

The TFPS converts hydraulic pressure data into a voltage signal that your Juke’s TCM/PCM can use to control the transmission. P0871 occurs when this signal is outside the normal operating range for this signal

So you have two scenarios:

  1. Your Juke has too little or too much transmission fluid.
  2. The sensor itself is bad.

P0871 Symptoms: Nissan Juke

These are the most common symptoms associated with P0871 in the Nissan Juke:

  • Clean Mode– Your Juke will shift differently and will not have access to all gears.
  • check engine light– There will often be other codes that occur with P0871. They are usually related to voltage and power.
  • Erratic change– Shifts may be smooth (RPM drops slowly during shifting), or they may be too abrupt (RPM drops sharply).

We do not recommend driving with this code as it may be an early warning of transmission failure.

Nissan Juke P0871 Causes + Diagnosis

P0871 Causes Juke

Diagnosing P0871 on the Nissan Juke can be challenging, due to the location of the TFPS sensor and the wiring associated with it.

1. Check other codes and TSB’s

The first thing you should do is look for other diagnostic codes. They can provide valuable clues about what’s happening within your stream.

TSBs are technical service bulletins. Nissan uses them to fix common and known vehicle problems. Check if there are any related to your problem. You can get them on the NHTSA website. This code may be returned with a very similar P0841.

2. Check the transmission fluid

If your Juke’s transmission fluid is too low or too high, it may throw this code. It only takes a second to check. Make sure you check it on a level surface to get a good reading.

2. Inspect the TFPS wiring

The next thing you’re going to want to do is inspect the wiring that goes to your Juke’s TFPS. If it is burned or damaged, you will need to replace/repair it.

After that, clear the fault codes from your Juke and see if the P0871 appears again

Whether or not you can access TFPS will determine whether most people can continue to diagnose P0871. TFPS can sometimes be accessed from outside the stream. You may need to break open the transmission, which means sending it to a transmission repair shop.

Wiring problems are the most common cause of P0871. Take your time and make sure the harness is in good condition.

3. Other causes

Although a bad TFPS sensor is very likely, make sure the voltage supplied to it is correct and does not change when you move the harness before replacing it.


Diagnosing P0871 is relatively simple. The real problem is getting to the wiring and the TFPS. Good luck repairing your Nissan Juke!
