The P1705 error code indicates a malfunction in the transmission range sensor circuit, which is responsible for detecting the gear position of the vehicle. This issue can affect the performance and drivability of Honda vehicles. In this guide, we’ll explore the symptoms, causes, and solutions, while emphasizing the importance of using professional diagnostic tools like the iCarsoft CR MAX and CR Eagle, which are advanced vehicle diagnostic tools and full OBD2 diagnostic tools.
1. What Does P1705 Code Mean?
The P1705 code is triggered when the Engine Control Module (ECM) detects an issue with the transmission range sensor circuit. In Honda vehicles, this sensor ensures that the vehicle’s transmission is in the correct gear, and a malfunction can lead to improper gear shifting or starting issues.
2. Symptoms of P1705 Code
- Check Engine Light illumination
- Difficulty shifting gears
- Vehicle stuck in one gear
- Inability to start the vehicle
- Erratic transmission behavior
3. Common Causes
- Faulty transmission range sensor
- Damaged wiring or connectors in the sensor circuit
- Blown fuse related to the transmission system
- Failed Engine Control Module (ECM)
- Corroded or loose electrical connections
4. Diagnostic Methods
Accurate diagnosis requires professional-grade diagnostic equipment like the iCarsoft CR MAX and CR Eagle, which are advanced bluetooth vehicle scan tools and full OBD2 diagnostic tools. These tools provide:
- OBD-II scanning to retrieve the P1705 code
