Error Code P0792: What It Means & What To Do?

<<See All OBD Codes

You have the OBD error code P0792 flashing in your vehicle, it’s now time to know a little bit about this error. Your vehicle's Powertrain Control Module or PCM, uses the information from the transmission intermediate shaft speed sensor in order to assist in desired shifting of the transmission. As the speed of the shaft increases gradually, the PCM continues its monitoring of the shifting operation, it does this until the shift point occurs. If the PCM notices that the shaft speed isn’t increasing or if the signal that is received form the intermediate shaft speed sensor is haphazard or not in range prescribed by the manufacturer, the PCM will store the P0792 code.

It is the job of the Intermediate Shaft Speed Sensor to inform the Transmission Control Module (TCM) how fast the intermediate shaft of the transmission is spinning, in-order to engage the right gear. If the TCM receives a faulty signal from this sensor, it won’t be able to properly shift the vehicle from gear to gear as needed by the driver. This is needed so that changes adapt to the change of speed and the acceleration rates. Upon noticing such issues, the PCM or the TCM will set P0792 error code.

What causes this problem with the Intermediate Shaft Speed Sensor A Circuit Range/Performance?

• Damaged wiring or connectors
• Fault in the Shift Solenoids
• Dirty or contaminated Transmission Fluid which is blocking the fluid passages
• Defectiveness in the Engine Drivability Sensors
• Defectiveness in the Engine Temperature Sensor
• Defectiveness in the Valve Body
• In rare cases there may be a malfunctioning PCM

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

• Begin the diagnosis of the P0792 code should start with an inspection of all the electrical components. Once you have repaired all the loose, damages, open, shorted, corroded or even malfunctioning electrical wiring and connectors, you can go ahead and clear all the codes set. Now you can proceed to retesting the system. If the code returns then it’s time to check the transmission fluid and be sure that it’s not dirty and contaminated. If you note that the transmission fluid smells burnt, then the entire system will have to be flushed and cleaned. After which, new fluid will have to be refilled.
• After performing these two steps of diagnosis, it’s time to now test the components and compare the voltage readings to ones prescribed by the manufacturer. Continue doing this till the correct component is found, attempt to repair the faulty components or replace if the damage is too extensive. The mechanic should then clear the code and retest the system and ensure that the whole problem was diagnosed and resolved.

Common Mistakes When Diagnosing the P0792 Code

There are several common misdiagnoses that can occur when the P0792 code is present. Some of them include fuel delivery problems, transmission problems, speed malfunctions or even driveline malfunctions. These all can often incorrectly be concluded as the culprits for the OBD error code. Vehicle speed sensors also are frequently replaced when it is unsolicited.
