The P0825 code in your 2020 Honda Accord indicates a malfunction in the gear lever position sensor circuit. This sensor provides critical information about which gear the driver has selected to the transmission control system.
Honda Accord Shifter System
The 2020 Accord uses a push-button shifter rather than a traditional lever for automatic models. The position sensor system determines which button has been pressed and confirms the transmission is in the requested gear.
Common Causes of P0825
- Shifter button switch failure
- Position sensor malfunction
- Wiring issues to shifter assembly
- TCM input circuit problem
- Connector corrosion
- Button mechanism damage
Symptoms of Position Sensor Failure
- Gear button not responding
- Incorrect gear displayed
- Check engine light on
- Transmission won't shift
- Multiple gear selections lit
- No-start condition possible
Push-Button Shifter Design
Honda's push-button shifter is electronically controlled with no mechanical linkage. Position sensing is entirely electronic, making sensor reliability critical for proper operation.
