Error Code P0933: What It Means & What To Do?

<<See All OBD Codes

The check engine light is on and you’re noticing an OBD error code P0933 is also flashing. It’s time to fix the issue but to be able to do that, you need to educate yourself with what’s happening in your vehicle and what led to the code being set. Here’s some information for you, to be able to understand the code, the parts related to it and how to eventually diagnose it properly and get rid of it. The Transmission Control Module sets this code when it notices an abnormal pressure present in the system. Read along to know more about the P0933 code.

The Transmission Control System of your vehicle electronically controls the line pressure which is measured by the Line Pressure Sensor or LPS. This pressure is compared on a continuous basis to the desired pressure and is accordingly electronically regulated by changing the duty cycle of the the Pressure Control Solenoid. The other job of the TCS is to calculate the desired line pressure, this is done based on the information received from the engine as well as the transmission. The primary input is the calculated torque input to the transmission, which is used to calculate the desired line pressure. It is also called a Torque Based Line Pressure. The TCM will set the error code P0933 when the hydraulic pressure sensor is showing undesired manufacturers specifications.

What causes this problem with the Hydraulic Pressure Sensor Range/Performance?

• Problems with the Hydraulic Pressure Sensor
• Damaged or faulty Hydraulic Pressure Sensor Harness
• Hydraulic Pressure Sensor which is shorted or open
• Poor Electrical Connection of the circuit

If you want to understand how to diagnose the generic OBD-II error code P0933 read on:

Before you start make sure you have the tools and information needed to proceed with the diagnosis. It is important to find the vehicle information source specific to your vehicle requirement. You will be able to find your vehicles Technical Service Bulletins inside it, make sure you match them accurately with the OBD code, symptoms as well as the make, model, year of manufacture and engine specifications. The TSB will give you priceless information on how to diagnose this error, it serves as a good reference point as well as directional source. All the connector pinout charts, component locations and other diagrams will help you a lot.

The P0933 code has an elaborate diagnosis. You should first start off by connecting the OBD scanner to the vehicle diagnostic port and retrieve all the codes. Freeze frame the data and go in the order to resolve them. It is important that all the preceding codes to the P0933 code are resolved, as they may have also been a reason for the code to set. Once you have resolved them, clear the codes and take your vehicle on a test drive. See if the code returns, if it does then continue diagnosis, by starting a thorough visual inspection of all the related wires, connectors and electrical components. All the burned, shorted, damaged wiring and circuitry will have to be either repaired or replaced. Once you have finished that, clear the code again, and go on another test drive to check if the code immediately returns. If it doesn’t then it’s highly likely that you were suffering from a intermittent condition, and in most cases the issue would have to worsen before correct diagnosis can be made. However if the code returns, then continue to test all the main modules, Transmission Control Module (TCM), Pressure Control Solenoid (PCS), Line Pressure Sensor or (LPS) etc, and see if the fault lies there. Every Time you do a repair, clear the codes and do a test ride to see if the issue has been resolved, this will save time, and help you understand what caused the code to set in the first place.

If you need extra help, contact a trained automobile diagnostician for assistance.

Common Mistakes When Diagnosing the P0933 Code

• Assuming a failed Hydraulic Power Unit Assembly
• Concluding a failed Transmission Control Module before checking other issues like electrical components
• Overlooking an issue with the wiring
