P2792: High Gate Select Direction Circuit OBD-II Trouble Code


Understanding manual gate selection is crucial for the ECU to optimize engine timing, fuel delivery, and other performance-related systems. If a high-voltage irregularity occurs, it triggers a P2792 Diagnostic Trouble Code (DTC).

How Serious Is A P2792 Code?

A P2792 diagnostic trouble code is linked to a system that directly impacts your vehicle’s drivability. It can lead to transmission issues, including erratic shifts, gear engagement failures, and diminished vehicle performance.

Common Symptoms of P2792

Typical symptoms associated with a P2792 code include:

    • Abrupt gear shifts
    • Erratic behavior of the transmission
    • Slippage between gears
    • Delayed gear transitions
    • Inability to engage specific gears
    • Decreased overall vehicle performance
    • Activation of limp mode

Potential Causes of P2792 Codes

Several factors can trigger a P2792 DTC, such as:

    • Damaged wiring and/or connectors
    • Broken shifter assembly or its components
    • Malfunction or misadjustment of the transmission range sensor
    • The potential for a defective shifter mechanism

Diagnosis of P2792 Code

When diagnosing a P2792 OBD-II trouble code, consider the following steps:

    • Inspect the condition of the wiring and connectors, checking for signs of damage or wear
    • Evaluate the functionality of the shifter assembly, looking for any defects or issues
    • Examine the transmission range sensor for potential malfunction or misalignment
    • Verify the software version in the Transmission Control Module (TCM), as an update may be required
    • Adjust the transmission range sensor if necessary

What Are Recommended P2792 Code Repairs?

To address the P2792 DTC, consider the following repairs:

    • Repair or replace any damaged wiring or connectors
    • Replace the shifter assembly if it is found to be defective
    • Adjust or replace the transmission range sensor to ensure proper functionality
    • Update the software version in the TCM if required

How Much Does It Cost To Diagnose or Repair a P2792 Code?

The cost associated with diagnosing a P2792 trouble code can vary:

    • If you have access to a code reader, you can retrieve the code independently.
    • Many local auto parts stores may offer code reading services at no charge.
    • If you choose to visit a transmission repair shop, there may be a fee for code reading and subsequent diagnostic procedures. Costs can range from minimal to several hundred dollars, depending on the complexity of the diagnosis.
