1. What is the P0705 OBDII Error Code?
The P0705 OBDII error code signifies a malfunction in the transmission range sensor (TRS) circuit, also known as the park/neutral position (PNP) switch. This sensor is crucial because it informs the powertrain control module (PCM) about the position of the gear shift lever. Whether you are in Park, Reverse, Neutral, Drive, or a specific gear, the TRS sends a signal to the PCM, allowing the vehicle to start, engage the correct gear, and activate features like the backup lights. When the PCM detects an irregular, intermittent, or absent signal from the TRS, the P0705 code is triggered. This issue can lead to various drivability problems and must be addressed promptly to prevent further damage to the transmission.

2. Understanding the Transmission Range Sensor (TRS)
The Transmission Range Sensor (TRS), also known as the Neutral Safety Switch or Park/Neutral Position (PNP) switch, is a critical component in your vehicle’s transmission system. Its primary function is to detect the position of the gear shift lever and transmit this information to the Powertrain Control Module (PCM). This information is vital for several reasons:
- Starting the Engine: The TRS ensures that the engine can only be started when the vehicle is in Park or Neutral, preventing accidental starts in gear.
- Activating Backup Lights: When the vehicle is shifted into Reverse, the TRS signals the PCM to activate the backup lights, enhancing safety.
- Gear Engagement: The PCM uses the TRS signal to determine the appropriate gear to engage, ensuring smooth and accurate shifting.
- Transmission Control: In modern vehicles, the TRS is also integrated with the transmission control system, providing data for electronic gear selection and shift patterns.
The TRS is typically located on the transmission housing, where it can directly monitor the movement of the shift linkage. It consists of a rotary switch with multiple contacts, each corresponding to a specific gear position. As the shift lever is moved, the switch sends a unique voltage signal to the PCM, indicating the selected gear.
2.1. TRS and PCM Interaction
The TRS communicates the gear shift lever position to the PCM. The PCM uses this information to:
- Control starting and prevent starting in gear.
- Engage the correct gear for driving.
- Activate backup lights when in reverse.
- Adjust transmission behavior for optimal performance.
2.2. Types of Transmission Range Sensors
There are primarily two types of TRS:
- Internal TRS: Located inside the transmission, requiring transmission removal for access.
- External TRS: Located on the outside of the transmission for easier access.
Choosing the right TRS for your vehicle is crucial. CARDIAGTECH.NET offers a wide selection of TRS units and diagnostic tools to ensure compatibility and performance.
3. Common Symptoms of a P0705 Error Code
When the P0705 error code is triggered, several noticeable symptoms may arise, impacting your vehicle’s performance and safety. Recognizing these signs early can help you address the issue promptly and prevent further complications. Here are the most common symptoms associated with the P0705 error code:
3.1. Illuminated Malfunction Indicator Lamp (MIL)
The most immediate sign is the illumination of the Malfunction Indicator Lamp (MIL), also known as the check engine light, on your dashboard. This light indicates that the PCM has detected a problem within the vehicle’s systems, and in this case, it is related to the TRS circuit.
3.2. Failure of Backup Lights
One of the most common symptoms is the failure of the backup lights to activate when the vehicle is shifted into Reverse. Since the TRS is responsible for signaling the PCM to turn on the backup lights, a malfunctioning sensor can prevent this from happening, posing a safety risk, especially in low-light conditions.
3.3. Starting Issues
A faulty TRS can cause issues with starting the vehicle. In some cases, the vehicle may start in any gear, which is a significant safety concern. Alternatively, the vehicle may fail to start in any gear, leaving you stranded. These issues occur because the PCM relies on the TRS signal to verify that the vehicle is in Park or Neutral before allowing the engine to start.
3.4. Irregular Shifting
The TRS plays a crucial role in the transmission’s shifting behavior. When the sensor is malfunctioning, the transmission may exhibit irregular shifting patterns, such as:
- Harsh Shifting: Abrupt and jerky gear changes.

- Inability to Shift: The transmission may fail to shift into the correct gear, leaving you stuck in one gear.
3.5. Reduced Fuel Economy
Erratic shifting and the transmission’s inability to select the correct gear can lead to reduced fuel economy. The engine may have to work harder to maintain speed, consuming more fuel than usual.
3.6. Transmission Stuck in One Gear
In some cases, the transmission may get stuck in one gear, which can severely limit the vehicle’s performance. This can occur because the PCM is not receiving accurate information from the TRS, preventing it from initiating gear changes.
3.7. Erratic Idling
The engine’s idle speed may become erratic, fluctuating up and down unexpectedly. This can be due to the PCM’s attempts to compensate for the inaccurate signals from the TRS.
3.8. Transmission Slipping
You may experience transmission slipping, where the engine revs up without a corresponding increase in speed. This can be a sign of internal transmission damage caused by the faulty TRS.
3.9. Difficulty in Shifting Gears
Some drivers report difficulty in physically moving the gear shift lever. This can be due to the TRS affecting the mechanical linkage of the transmission.
3.10. No Start Condition
In severe cases, a malfunctioning TRS can prevent the vehicle from starting altogether. This can be a frustrating and inconvenient issue, often requiring immediate attention.
3.11. Additional Electrical Issues
The error can affect electrical functions connected to the gear selection, such as cruise control or gear-specific indicators on the dashboard.
Recognizing these symptoms and understanding their connection to the P0705 error code will enable you to take prompt action, diagnose the problem accurately, and implement the necessary repairs. Timely intervention not only restores your vehicle’s performance but also prevents potential damage to the transmission and other critical components.
