Before we dive into the solution, let’s first understand what this issue is all about. The P1709 code is a diagnostic trouble code (DTC) for “Digital TRS Failed to Transition States in KOEO / KOER”. This can occur when there’s a problem with your vehicle’s transmission range sensor (TRS).

What is a Transmission Range Sensor (TRS)?

The Transmission Range Sensor (TRS) is a switch that tells the engine control module (ECM) the position of the transmission shifter. When the TRS fails to transition states in KOEO (Key On Engine Off) or KOER (Key On Engine Running), it triggers the P1709 code.

First, use an OBD-II scanner to check for any stored DTCs. If the P1709 code is present, it indicates a problem with the TRS.

Step 2: Inspect the TRS

Next, inspect the Transmission Range Sensor for any visible damage or loose connections.

Step 3: Test the TRS

Use a multimeter to test the TRS. If it fails the test, it needs to be replaced.

Solving the P1709 Issue
