P0793 Code: Intermediate Shaft Speed Sensor “A” Circuit No Signal

The intermediate shaft speed sensor measures the rotational speed of the intermediate shaft in vehicles with an automatic transmission or transaxle. The input coming from the sensor is sent to the transmission control module (TCM) so that the proper gear can be engaged. If the intermediate shaft speed sensor is unable to send a signal to the module, on-board diagnostics (OBD) will log a P0793 code.

What Does the P0793 Code Mean?

Diagnostic trouble code P0793 stands for “Intermediate Shaft Speed Sensor ‘A’ Circuit No Signal.”

The powertrain control module (PCM) relies on the input from the speed sensor for adaptive learning and self-diagnosis.

The intermediate shaft, which transfers torque from the engine to the transmission, has a speed sensor that tells the TCM how fast the shaft is spinning. This allows the control module to apply the appropriate gear.

Inaccurate signals coming from the intermediate shaft speed sensor can prevent the vehicle from shifting properly because the speed and rates of acceleration are different from the ones the sensor is sending to the TCM.

Note: The definition of code P0793 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P0793 Code?

• Intermediate shaft speed sensor failure
• Wiring issues
• Transmission control module failure
• Powertrain control module failure

What are the Common Symptoms of the P0793 Code?

• Illuminated check engine light
• Transmission might not shift properly
• Increased fuel consumption

How to Diagnose the P0793 Code

DTC P0793 is a generic powertrain code that applies to vehicles equipped with an OBD-II system. While this might be the case, keep in mind that the vehicle’s year, make, and model can affect the protocols for diagnosing this trouble code.

The diagnostic process usually involves using a scan tool and inspecting the affected system. If you’re not familiar with how the job is done, you can always ask a certified mechanic to help you out. Otherwise, you can go ahead and do it yourself.

How to Fix the P0793 Code

Without the right tools and technical information, attempting to fix a P0793 trouble code can be tricky and frustrating. It can even lead to further complications and expensive repairs if done incorrectly. If you’re not confident with your DIY skills yet, it’s a good idea to bring your vehicle to the nearest auto repair shop and have a professional perform the necessary repairs. This will ensure that all steps and protocols are followed correctly.

But if you have some experience in dealing with trouble codes, then you know that there’s no one-size-fits-all solution for all makes and models. So before you begin, make sure to consult guides like those from Chilton or an ALLDATA subscription to get vehicle-specific repair information.
