2015 nissan altima pressure control solenoid b location

|What are the Possible Causes of the Code P0776 Nissan?

Low transmission fluid level
Dirty transmission fluid
Faulty line pressure solenoid 'B' valve
Line pressure solenoid 'B' valve harness is open or shorted
Line pressure solenoid 'B' valve circuit poor electrical connection

|How to Fix the P0776 Nissan Code?

Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

When a transmission solenoid is malfunctioned, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure and that the transmission will need to be rebuilt or replaced.

There is factory service bulletin for the following Nissan Models:
2015-2016 Nissan Altima with 4 Cylinder Only
The factory service bulletin recommends replacing the Transmission Valve Body to repair the problem.

|What is the Cost to Diagnose the Code P0776 Nissan?

Labor: 1.0

The cost to diagnose the P0776 Nissan code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P0776 Nissan Code Detected?

The gear required by the Engine Control Module (ECM) does not match the actual gear when driving

|What are Code P0776 Nissan Possible Symptoms?

Engine Light ON (or Service Engine Soon Warning Light)
Transmission shift shock

|What Does the P0776 Nissan Code Mean?

The Pressure Control (PC) Solenoid Valve an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field produced by the coil moves the solenoid’s plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure regulated by the PC solenoid valve, which ultimately decreases line pressure. The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).

P0776 code definition

Code P0776 is an indication that your vehicle’s PCM has found an abnormality related to the electronic pressure control solenoid circuit or simply the solenoid itself.

What the P0776 code means

The computer-controlled automatic transmission relies on varying levels of hydraulic pressure to supply torque converter and shift actuation lockup. Pressure is controlled by using at least one electronic pressure control solenoid. This is overseen by the PCM.

Although it’s a bit different across all makes and models, almost every application relies on calculations based on engine load, engine speed, throttle position and vehicle speed to measure the appropriate degree of pump pressure necessary for efficient operation. Should the amount of fluid deemed necessary not coincide with the actual amount used, code P0776 is stored and the Check Engine Light should come on. It’s worth noting, though, that in some applications, the light won’t be activated until several failure cycles.

What causes the P0776 code?

This code could be stored for lots of reasons. Some of the more common ones include:

An electronic pressure control solenoid that isn’t working
Mechanical internal transmission errors
The internal transmission fluid passages are suffering from hydraulic blockages
Low transmission fluid
Contaminated transmission fluid
Mechanical internal transmission failures
Faulty PCM

What are the symptoms of the P0776 code?

This code could make for a wide range of symptoms. In some situations, drivers don’t actually detect anything noticeably wrong with their vehicle. Other times, their shifting function may become completely disabled. Your torque converter clutch could fail to engage or disengage. Sometimes, when this code is stored, the PCM responds by putting the vehicle into “limp-in” mode.

Other common symptoms include:

Transmission slippage
Harsh shifting
Decreased fuel efficiency
Transmission overheating

How does a mechanic diagnose the P0776 code?

The mechanic will use an OBD-II scanner to find out which codes have been stored by your vehicle’s PCM. Then their diagnosis process will move to checking on the level and quality of the transmission fluid. They may even need to inspect the transmission pan. Next, they’ll examine the connectors, wiring and other electrical components. In rare cases, they may need to take a look at the actual PCM as well.

Common mistakes when diagnosing the P0776 code

A lot of times, mechanics focus on a vehicle’s high pressure pump and eventually even replace it when the actual solution lies with wiring malfunctions or the electronic pressure control solenoid.

How serious is the P0776 code?

As you can probably tell from the list of symptoms above, this is definitely a code you want to have fixed right away. Driving your vehicle won’t be easy as long as the problems related to this code are around. Furthermore, even if you are only experiencing mild symptoms at the moment, those could get worse in the near future.

What repairs can fix the P0776 code?

Your mechanic will most likely:

Repair/replace faulty electrical components
Replace/fill the transmission fluid
Replace the clutch (if it’s been damaged by low transmission fluid amounts)
Replace the PCM (very rare)

This code can represent multiple issues and is associated with plenty of other problem codes too. Therefore, it would be wise to adjust each of them in the order they were stored. That’s the best way to ensure you don’t miss any major problems. After each repair, be sure to clear the system, too, so you can see if any others still exist before moving on.

Where is the pressure control solenoid B location?

Pressure control solenoids are located inside the transmission and are responsible for controlling pressure within the transmission's hydraulic circuits.

How do you fix the code P0776 on a Nissan Altima?

What repairs can fix the P0776 code?.

Repair/replace faulty electrical components..

Replace/fill the transmission fluid..

Replace the clutch (if it's been damaged by low transmission fluid amounts).

Replace the PCM (very rare).

What is pressure control solenoid B mean?

The P0775 code is triggered when the PCM detects pressure control solenoid “B” is experiencing a malfunction. A malfunctioning transmission solenoid can be caused by low or dirty transmission fluid, wiring issues, or simply old age.
