Pressure control solenoid code

I am getting a pressure control solenoid code P0795.
Experienced mechanics share their insights in answering this question :
Hello. There are several reasons why you might get this code. Your transmission fluid could be dirty or low, or there could be a faulty pressure control solenoid in valve ’c’. All of these conditions need to be check by a certified technician so that a proper diagnosis can be made as to why you are getting this code.

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

P0745 is a diagnostic trouble code (DTC) for “Pressure Control Solenoid Malfunction”.
Pressure control solenoids are located inside the transmission and are responsible for controlling pressure within the transmission`s hydraulic circuits. Transmission fluid allows the transmission to change gears because it creates hydraulic pressure that moves the gears to their appropriate positions.
More about the P0758 code

Shift solenoid B allows the transmission to shift between 2nd and 3rd gear. When the powertrain control module (PCM) records code P0758, it indicates that the PCM is unable to detect the proper change in engine speed or increase in ground speed that should occur during a 2nd to 3rd gear shift.

P0758 is a diagnostic trouble code (DTC) for “Shift Solenoid B Electrical/2-3 Shift Solenoid Circuit Electrical”.
P0777 code definition

A P0777 trouble code signifies that the Powertrain Control Module (PCM) has detected a fault in one of the electronic pressure control solenoids or solenoid circuits.

A P0746 code means your vehicle`s computerized system isn`t in full control of your car`s torque converter or transmission. As such, you are likely to experience various problems, including overheating, a stalling engine, and a non-working or slipping transmission.
P0841 indicates there is an issue with the transmission fluid pressure sensor or switch “A” circuit`s performance. More specifically, this code indicates that the sensor has found out-of-range pressure or abnormalities in the transmission fluid pressure within that sensor`s circuit.
P0076 is an OBD2 code that indicates an issue with the Bank 1 intake valve control solenoid circuit. This tells us that the car`s computer, or Engine Control Module (ECM), has detected a sensor that is out of the specified voltage range.
If your OBD-II scanner shows a P2714 code, it means that your engine control module (ECM) has detected a problem with solenoid D in your automatic transmission. When you change gears, your transmission needs to have the right fluid pressure.
The diagnostic trouble code (DTC) P2715 indicates “Pressure Control Solenoid “D” Stuck On.” It applies to any vehicle with an automatic transmission that has multiple pressure control solenoids. P2715 code applies to any vehicle with an automatic transmission that has multiple pressure control solenoids.

ANSWER : Hi there. The trouble code you indicated is similar in many ways to the P0963 OBD-II code. This article should give you a lot of valuable data that will explain the source of this code, possible causes and repairs. In general, this code is related to a communication error with the transmission pressure control solenoid. Most of the time, the code is triggered due to the solenoid being dirty, or the connections are loose. When this happens, the OBD-II trouble code essentially activates a fail safe mode, so that the car will not continue to damage the transmission or other components.

ANSWER : Hello, thank you for writing in. The reason your are not getting a response from your gas pedal is due to the transmission fluid pressure is off, or the computer thinks it is. Typically this is caused by a bad solenoid used to regulate the pressure, or the connection to the solenoid is weak. A weak connection can be caused by the physical wires being loose or dirty, or from the solenoid being loose or dirty. Make sure everything is clean, dry, and tight before replacing the solenoid.

Check engine light came on, diagnostic was done and came up with codes saying pressure control solenoid 2,3, & 5 are shut off.
ANSWER : Low transmission fluid is a major cause of transmission failures. Your pressure control solenoids turned off to try to prevent damage to transmission components like clutches etc. Unfortunately, the damage is done and changing the fluid will not help, and most shops will not do a fluid exchange on your transmission with so many miles. You will need to have your transmission tested by a certified mechanic. More than likely, you will need to have your transmission rebuilt.

If you’d like a second opinion on this, get your car inspected by a certified technician, such as one from YourMechanic. They will be able to help you diagnose your Check Engine Light further. Best of luck.

ABS, ESP, EBR malfunction
ANSWER : You’re getting into an area that is kind of a dark art when you’re getting these kinds of codes. While I don’t know any of the symptoms that the car is exhibiting, I can tell you that failure in one of the control units can lead to codes showing up in the others and the ABS, ESP is a likely culprit since it interprets the wheel speed signals and sends the information to the other modules. You’re right that the module has to be coded, and I don’t think that Snap On has the software for that so the only place to go is the Star Diagnostic. (The consumer version of the Mercedes SDS ) You can Contact YourMechanic and see if anyone in your area has the appropriate equipment for this. Otherwise, this may be a case that would best be consigned to the Mercedes Dealer.

Check Engine Light codes. 2006 Mercedes Benz E55 AMG
ANSWER : Since you are getting many different codes from different areas of the engine, you may need to have the system hooked up to a factory scanner since most of these generic codes do not cross over in my repair software. I would also check with the local dealer to see if any service campaigns are open on the vehicle since there are over 30 possible campaigns that could pertain to this vehicle and some of the problems you are having with the secondary air system. This may be the cause of some of the codes and supercharger disabling. If you’d like to have this checked elsewhere, a qualified pro from YourMechanic can come to your car’s location to go through each Check Engine Light code firsthand and have them resolved.

My car has low oil pressure. I’ve already changed the oil pressure sensor 3 times.
ANSWER : If you have replaced the sensor three times and it did not fix the problem, then you may have problems with the oil pressure being low at idle due to wear in the engine bearings. The reason it would be fine sometimes and not others may be due to engine load and temperature changes. Have the oil pressure tested at the sensor port to see if it is low and needs engine repairs.

I recommend having a certified mechanic, such as one from YourMechanic, come to your location to perform an inspection to determine why the Oil Pressure Light is on.

I have a Code P0601 on the PCM. I replaced the PCM, and now I have a code P0118, code P0123, and code P0193.
ANSWER : Hi there, the short answer to your question is no . A PCM with a P0601 (which is a memory module error in the PCM) cannot reliably retrieve codes for the codes you list (P0118 – coolant temp sensor, P0123 – throttle position sensor, P0193 – fuel rail pressure sensor.

Most likely, the P0601 prevents the PCM from getting any codes from the engine sensors. The memory module error may cause in data corruption for collected sensor values, lose of data over multiple sampling periods, or failure of the data collection to work at all. Replacing the PCM was a necessary expense.

If you need assistance with the "new" codes, I would recommend having a Check Engine Light inspection completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose the new error codes and get an accurate assessment of the repairs needed.

Code for pressure solenoid D
ANSWER : The P2716 code is produced when the ECM has detected that the throttle body actuator motor has failed to read the correct position at which the butterfly valve within the throttle body should be in order to produce a smooth idle for the engine. C1201 relates to the vehicle stability control system and can be triggered for many reasons such as malfunctioning ABS or brakes or in some cases when electronically controlled suspension is not working properly. I would recommend having an expert from YourMechanic come to your home to take a look at the vehicle and diagnose the Check Engine Light and possibly conduct a test drive to ensure there are no safety issues related to these codes.
