Code P0706 2020 Honda CR-V Description
The P0706 diagnostic trouble code (DTC) for the 2020 Honda CR-V indicates a Transmission Range Switch Open. This code is typically triggered when the powertrain control module (PCM) detects an open circuit in the transmission range switch, also known as the neutral safety switch. The transmission range switch is responsible for indicating the gear position (Park, Reverse, Neutral, Drive) to the PCM, allowing the vehicle to start and shift gears properly.
Common Causes of P0706 2020 Honda CR-V
- Faulty transmission range switch
- Damaged wiring or connectors related to the transmission range switch
- Corrosion or moisture in the transmission range switch circuit
- Issues with the PCM or related control modules
- Electrical issues such as a blown fuse or relay affecting the transmission range switch circuit
Symptoms of P0706 2020 Honda CR-V
- Difficulty starting the vehicle
- Inability to shift gears
- Incorrect gear indicator on the dashboard
- Stalling while driving
- Harsh shifting or erratic transmission behavior
How to Fix P0706 2020 Honda CR-V
- Begin by diagnosing the transmission range switch circuit using a multimeter to check for continuity and proper voltage.
- Inspect the wiring and connectors for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test the transmission range switch itself for proper operation. Replace if found faulty.
- Clear the DTC from the PCM memory using a scan tool and perform a test drive to ensure the issue is resolved.
- If the problem persists, further diagnosis of the PCM or related control modules may be necessary.
