The P0707 code is an OBD-II trouble code that indicates a problem with the Transmission Range Sensor “A” circuit being low. This sensor, also known as the PRNDL input or neutral safety switch, plays a crucial role in informing the vehicle’s control modules about the current position of the transmission.
What Does the P0707 Code Mean?
When your vehicle’s onboard diagnostics system detects that the Transmission Range Sensor is providing a low voltage signal, it triggers the P0707 code. This means that the Transmission Control Module (TCM) and Engine Control Module (PCM) are receiving incorrect data regarding the transmission’s gear position.
What Causes the P0707 Code?
Several factors can lead to the setting of a P0707 code, including:
- Failure of the Transmission Range Sensor
- Wiring issues, such as frayed or shorted wires
- Powertrain Control Module (PCM) failure
- Transmission Control Module (TCM) failure
What Are the Symptoms of the P0707 Code?
Drivers may experience a range of symptoms when the P0707 code is triggered, including:
- Increased fuel consumption
- Transmission may not shift properly
- Erratic shifting or inability to shift gears
How Serious Is the P0707 Code?
The P0707 code is categorized as urgent. It indicates significant malfunctions that can lead to severe damage to the vehicle or pose safety risks to the driver and passengers. Immediate attention is recommended to prevent further damage.
How to Diagnose the P0707 Code
A proper diagnosis of the P0707 code involves several steps:
- Use an OBD-II scanner to confirm the P0707 code and check for any other related trouble codes.
- Inspect the transmission range sensor and its wiring for signs of damage or wear.
- Test the transmission range sensor’s output voltage with a multimeter.
- Check the functionality of the PCM and TCM if no issues are found with the sensor.
Common Repairs for the P0707 Code
Repairs for the P0707 code may include:
- Replacing the Transmission Range Sensor
- Repairing or replacing damaged wiring or connectors
- Replacing the Powertrain Control Module (PCM) or Transmission Control Module (TCM) if necessary
How Much Does It Cost to Fix the P0707 Code?
The cost to fix the P0707 code can vary widely depending on the underlying issue. Generally, you can expect:
- Transmission Range Sensor replacement: $100 to $300
- Wiring repairs: $50 to $200
- PCM or TCM replacement: $500 to $1,500
Can I Fix the P0707 Code Myself?
If you have experience with automotive repairs, you may be able to diagnose and fix the P0707 code yourself. However, if you are unsure or lack the necessary tools, it is advisable to consult with a professional mechanic to avoid further complications.
