Naturally, repair and inspection should be done in the shortest time possible. This will reduce the chance of damage spreading to the other components.

Scroll down for more in-depth details and also the guidelines for the P0841 code.

What is the P0841 Code? Nissan Altima?

The Definition

If you conduct a bit of investigation into everyday issues that affect automobiles, you’ll find that P0841 is a DTC (Diagnostic Trouble Code).

This refers to “Transmission Fluid Pressure Sensor/Switch “A Circuit Range Performance.”

Typically, this code is utilized on most modern cars equipped with OBD-II diagnostics.

So, if you’d like to know more about this issue in other models, such as those of the P0841 Nissan Altima 20142017 Nissan Altima P0841, or even the P0841 Nissan Rogue, the following info is valuable and can be used.

Then, when will this code appear?

Other less frequently reported causes include broken balls in valve bodies, leaks inside the valve, or leaks. These are the mechanical problems that lead to this error.

Most of the time, it is an electrical issue.

To put it simply the meaning of this sensor (TFPS) converts pressure into an electrical signal to the powertrain controller module (PCM) or the transmission control module (TCM).

In this case, the input may be outside the range of both modules.

This means it is difficult for TCM and PCM to detect the voltage on the line. This code will indicate that there is an issue.

In addition to P0841, other error codes are similar to this one, including:

  • TFPS/Switch “A” Circuit: P0840
  • Switch/TFPS “A” Circuit low P0842
  • Switch/TFPS “A” Circuit High P0843
  • Switch/TFPS “A” Circuit Intermittent P0844

How Serious is It?

It will not immediately stop the transmission, like in other vehicles. This means that you’ll be able to continue driving your car.

It’s hazardous in that the transmission may suddenly shift or switch, putting other drivers at risk.

Furthermore, the transmission problem identified by the engine code P0841 can be hazardous.

This is why repairing or bringing your vehicle to the repair shop is recommended when you spot something like this.

Reasons For P0841 Code

Most Common Causes

As we all know, many reasons led to the creation of this P0841 number. There are a few of the most popular reasons to look into first are

  • Problems are a problem with problems with 2016 Nissan Altima transmission fluid pressure sensor location (this is the same as the 2017 Nissan Altima transmission fluid pressure sensor location or other models of the year)
  • Transmission problems: Internal or the liquid that is low in transmission
  • PCM or TCM quality issues

How to Find

It’s recommended that you begin by examining any other codes for diagnostics. They could contain vital information regarding what’s happening inside the gearbox.

TSB is the abbreviation for Technical Service Bulletin. Nissan utilizes them to address frequently asked auto issues. Examine the issue to determine the ones relevant to your particular issue.

Concerning TFBS ones, look at the wiring for the Altima’s TFPS. You’ll have to replace or repair it if it’s damaged or burned.

Most people cannot continue diagnosing P0841 if they cannot gain access to TFPS.

Fortunately, the TFPS can be accessed by a non-transmission source, requiring you to unlock the transmission.

To recognize the problem with the liquid in the transmission, it is possible to refer to the method that mechanics who are professionals typically apply:

Check the dipstick for transmission fluid before starting the transmission diagnosis.

Ensure that the liquid is in good condition and within the recommended range of the manufacturer.

  • The liquid is odd or smells burnt. It is not enough and must be replaced. A burned one is a good indicator that the fluid level is not adequate. It could be an indication of an internal mechanical problem in the vehicle.

Also, look for shorted or burned wire, and then repair connectors and circuits that appear lousy.

Attach your scanner’s diagnostic port, and take note of all freeze frame data and error codes if the wires and connectors of the system and other components are in good shape.

  • The fluid level is low but in good condition. Make sure to add more liquid and then check for any issues.

The Most Common Symptoms Of P0841 on Nissan Altima 2016

If you’re wondering how to identify a problem with the P0841 vehicle code, you can learn more about the typical symptoms below.

Of course, this won’t be the case in all situations, but over 90% of cars have this issue. It’s one or more of the following:

  • Check Engine Light flashes. It is a sign of the voltage and power. However, it could also be a sign of other problems. For more details, you can look into theĀ intermittent checking engine lights that flash problems.
  • Quality of the shift: A gear may shift unexpectedly, and you can’t control it. P0841 code is among the most frequent reasons forĀ shifting, but it doesn’t change the gears.
  • Consumption of fuel: This consumption will be higher, and the efficiency of the fuel-economy function will decrease.

It is known that a long-lasting stressor in the drivetrain can be the cause of sensor problems in a lot of older vehicles. A P0841 code could have various meanings, making identifying and correcting challenging.

The best option is to bring your vehicle to a mechanic equipped with the proper equipment to diagnose the problem more thoroughly and speedily.

How to Repair P0841 NISSAN Altima 2016

Simple causes like the lack of fluid levels are easily fixed by flushing or filling it at home.

However, experts must examine and repair the more complex ones connected to the TFPS or other parts.

What Is It Going To Cost to Repair?

It’s challenging to establish the exact amount because it is influenced by numerous factors like the source of the damage and its condition, the car as well as the quality of parts that are on the vehicle, and the cost of living in your local area as well as the center for service, etc.

If you want a certified mechanic to assess and diagnose the car’s condition the cost is between $75-$150.

For replacements, around $90-$120 will be the cost for the fresh 2015 or 2017 Nissan Altima transmission fluid pressure sensor. The cost of an additional fluid can go up to $200.

You will need to budget between $400 and $550 to cover this repair. It’s not an insignificant amount!

Do I Have the Ability to Repair It by myself?

In the preceding section, we’ve discovered more than one possible cause for P0841’s code. For simple root causes, it is possible to repair it yourself at home and reduce costs.

Topping off the fluid or cleaning the transmission will quickly resolve minor problems like the transmission fluid being dirty or low.

Be aware of this since a slight error can cause more damage. Particularly in the case of more complex problems connected to the TFPS, PCM, or TCM, skilled mechanics must perform repairs.

Easy step for refilling or flushing the fluid yourself:

  • Set your car in a flat area and search for the reservoir of your transmission fluid.
  • Make sure the fluid is at the right level using the dipstick.
  • The amount of fluid will increase within the tank if it appears that the dipstick is clear. Clean the system if it’s darker brown, or black hue.
  • Then, lift your car using Jack stands. In this process, make sure to leave room to walk under it.
  • Find the pan of transmission fluid underneath the car. Set an empty container (bucket) beneath it.
  • Pour the rest of the fluid into the bucket you have set aside after removing the drain plug.
  • Refilling the reservoir by putting a funnel into the reservoir and pouring in fresh transmission fluid is possible.
