Guide To P2733 OBD Error Code Solutions

<<See All OBD Codes

It can be very difficult to figure why the P2733 code has been set, and it can also cause a lot of stress when you need your vehicle to be working properly. But we are here to give you all the information about this OBD error code. This code is defined as a Pressure Control Solenoid "F" Stuck On.Your vehicle's Transmission Control Module makes use of the Pressure Control Solenoids in order to control the hydraulic pressure in the transmission. This hydraulic pressure is required to be able to apply the various clutch packs needed to change gears as needed by the driver. All of this is needed to be able to propel the vehicle efficiently on the road. If the TCM is able to detect an issue with the pressure control solenoid is not working as needed, this P2733 code is set.

An electronic pressure regulator is present in the Pressure Control (PCM) solenoid valve, which controls the transmission line pressure based on current flowing through the coil windings. When the current flow is increased, the magnetic field produced by these coil helps the solenoid to plunger further away from the exhaust port. Whenever the exhaust port opens, it decreases the output fluid pressure. This is regulated by the PC solenoid valve which also has the capacity to decrease the line pressure. The oil pump discharge pressure is regulated by the line pressure solenoid valve, this is done to suit the driving condition as needed by the signal sent by the Transmission Control Module (TCM).

What causes this problem with the Pressure Control Solenoid "F" Stuck On?

• Problem in the Pressure Control Solenoid
• The transmission fluid is dirty or contaminated
• The filter of the transmission is either dirty or clogged
• Defects present in the Transmission Pump
• Issues with the Transmission Valve Body
• Constraints in the hydraulic passages
• Connectors are damaged or corroded
• Problematic wiring
• Malfunction of the Powertrain Control Module

1. Pressure Control Solenoid - Performs the job of controlling the pressure for the fluid which is present in the internal friction plate clutches or drum bands. When the Pressure Control Solenoid is not working properly, it can cause the transmission to slip, which can result in an overheated transmission. So, it’s important to fix the PC solenoid, you may have to replace it. In such a case find the best quality PC solenoid on PartsAvatar online.
2. Electronic Pressure Regulator - Uses a push valve and a vent valve to maintain the outlet pressure at the desired set-point. Your vehicle has a small internal pressure sensor which allows it to monitor the output pressure. There’s also a digital or analog controller that adjusts the timing of the servo valves to maintain the set-point. You may have the P2733 code because of a faulty regulator, in such case try to repair it first. If repairs don’t help, you will have to find a replacement. Find it online from the comfort of your home on PartsAvatar. We stock over 3 million replacement parts!
3. Transmission Control Module - An important component of an automatic transmission vehicle, the TCM has to be work efficiently for the vehicle to function properly. Rectify a faulty TCM via repairs, if that doesn’t help get rid of the P2733 code, you will have to replace it. For replacement, you can log onto our website and choose from a wide range of brands and price options.
4. Powertrain Control Module - This is the center point of your vehicle that monitors every other module. Its job is to detect issues and inform the driver by setting the OBD codes such as the P2733 code. When the PCM has become problematic, you will have random codes set, and also the vehicle will not work properly. So, fix it or go for a replacement at PartsAvatar. We ship all across Canada from our warehouses.
5. Transmission Filter - It is located above the transmission pan and below the pickup tube which connects to the oil pump. This filter facilitates in regulating the pressure of the fluid in the transmission. Hence you are able to experience smooth drivability. If you have a blocked filter, it will require to be cleaned or even replaced if needed. Find superior quality transmission filter from top brands. Search by vehicle year, make and model and find the perfect fitment for your vehicle today on PartsAvatar.
6. Transmission Pump - The pump is typically located in the cover of the transmission. Its job is to draw fluid from a slump in the bottom of the transmission and feed it to the hydraulic system. It also feeds the transmission cooler and the torque converter. The P2733 code may have been set due to a damaged pump, try to repair or replace it as needed.
7. Transmission Valve Body - Is a significant component of the transmission system and works in a network form. This network of valves is where the transmission body directs pressurized transmission fluid to. The valves then apply the right clutch packs for the gears to work smoothly and efficiently.

After knowing all the cause behind the issues, let’s have a look at a few common symptoms of this problem. Read through this section to learn more about this error code.

Common Symptoms

• The PCM puts the vehicle in limp mode
• Transmission slips
• Overheating of the Transmission
• Transmission tends to catch in gear
• Lowered fuel economy
• Some misfire-like symptoms are present
• The check engine light is on

Want to correct the Trouble Code P2733? Read these points mentioned below:

• Change the fluid and clogged filter
• Repair or replace the problematic Pressure Control Solenoid
• The faulty transmission pump will have to be repaired or replaced
• The defects of the transmission valve body have to be fixed
• You will have to flush the transmission passages
• Clean the corrosion that are present on the connectors
• The wiring will have to be repaired or replaced as needed
• Flash the PCM

We are sure that now all your issues would be resolved.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

The first step to a thorough diagnosis is to research the Technical Service Bulletins (TSB’s). For this you will have to match your vehicle’s year of manufacture, model and transmission. The reason why the TSB should be referred is mainly to save you time, and effort. It serves as a great tool during diagnosis.

Fluid Check

Measure the level of fluid and also observe the condition of the fluid for any dirt or contamination. Don’t be hasty in changing the fluid, check the vehicle records to see when the fluid and filter change was done last. Depending on what you have found, you can proceed to changing the fluid or simply skip this step if the fluid level and purity is good.

Wiring Inspection

Moving on to the wiring, perform a detailed visual examination and see if there are any damages present. Continue inspection of the connectors and see if the pins are corroded, bent or damaged. Check the wires and connectors going to the transmission pressure solenoids, transmission pump as well as the PCM. Depending on the type of vehicle the transmission pump may be driven electrically or mechanically. Fix all the issues you have found by conducting repairs or replacements as required.

Continuity Check

These will be done to figure out the problem if it wasn’t with the fuel, filter or electrical components.

Continuity check is an advanced step, and hence will need certain tools like a digital multimeter and the specific technical references for the vehicle. Get hold of them and also all the troubleshooting information for your particular vehicle from the TSBs.

Voltage Check

To confirm the voltage and fluid pressure requirements you will need to refer the TSBs. In terms of continuity checks, they will usually be 0 ohms of resistance, but for safety refer your vehicles information source. When performing the continuity checks you have to ensure that power is removed from the circuit. This is important to avoid shorting the circuit and causing more damage to the vehicle. If you find that there is no continuity or resistance then that’s an indication that there is faulty wiring present which may be open or shorted and needs to be repaired/replaced.

Common Mistakes When Diagnosing the P2733 Code

• The TCM has failed
• Transmission fluid level is not at the right level
• Transmission shift solenoid malfunction
• Failed wiring
