Code P0707 Description
The P0707 diagnostic trouble code (DTC) indicates a problem with the transmission range sensor circuit having a low input signal. The transmission range sensor, also known as the neutral safety switch or park/neutral position switch, is responsible for sending signals to the vehicle's powertrain control module (PCM) to determine the gear position of the transmission. This information is crucial for proper shifting, torque converter lockup, and other transmission functions.
Common Causes of P0707
- Faulty transmission range sensor
- Damaged wiring or connectors in the sensor circuit
- Misadjusted sensor position
- Malfunctioning PCM
- Corrosion or water damage in the sensor circuit
Symptoms of P0707
- Harsh or delayed shifting
- Inability to shift gears
- Difficulty starting the vehicle
- Check Engine Light illuminated
- Transmission slipping or erratic behavior
How to Fix P0707
- Begin by diagnosing the issue using a scan tool to retrieve the specific trouble code and further investigate the transmission range sensor circuit.
- Inspect the transmission range sensor, wiring, and connectors for any visible damage or corrosion. Replace or repair any damaged components as needed.
- Adjust the sensor position if necessary to ensure proper alignment and function.
- Clear the trouble code from the PCM memory and test drive the vehicle to verify that the issue has been resolved.
- If the problem persists, further diagnosis may be required to pinpoint the exact cause, such as testing the sensor's output voltage and signal continuity.
Cost to Fix P0707
The cost of repairing a P0707 code can vary depending on the root cause of the issue. On average, the parts for a transmission range sensor replacement can range from $50 to $200, while labor costs can range from $100 to $200. Overall, the total repair cost for this issue may fall between $150 to $400. It is important to note that these estimates are approximate, and actual costs may vary based on factors such as location, vehicle make and model, and labor rates at the auto repair shop. It is recommended to consult with a professional mechanic for a more accurate cost estimate.

Frequently Asked Questions about P0707 Code
1. What does the OBDII code P0707 mean?
P0707 indicates that the Transmission Range Sensor (TRS) is reporting a low input signal to the Powertrain Control Module (PCM), suggesting an issue with the sensor or its circuit.
2. What are the common symptoms of a P0707 code?
Symptoms may include the vehicle stuck in limp mode, difficulty shifting gears, erratic transmission behavior, a check engine light, or the inability to start the vehicle.
3. What causes the P0707 code to appear?
Common causes include a faulty transmission range sensor, damaged wiring or connectors, misaligned gear linkage, or issues with the PCM.
4. Can I still drive with a P0707 code?
Driving with a P0707 code is not recommended as it can cause further damage to the transmission and may result in unsafe driving conditions.
5. How do I diagnose a P0707 code?
Diagnosis involves scanning the vehicle with an OBDII tool, inspecting the TRS and its wiring for damage or loose connections, and verifying proper alignment of the gear selector.
6. What is the transmission range sensor, and what does it do?
The transmission range sensor detects the position of the gear selector and sends this information to the PCM to manage shifting and engine behavior.
7. How can I fix a P0707 code?
Possible fixes include replacing the transmission range sensor, repairing damaged wiring or connectors, adjusting the gear linkage, or reprogramming the PCM if necessary.
8. How much does it cost to fix a P0707 code?
Repair costs vary but typically range from $150 to $400, depending on whether the TRS needs replacement or if additional wiring repairs are required.
9. Can a P0707 code cause starting issues?
Yes, a faulty transmission range sensor may prevent the vehicle from starting, as the PCM may not detect the proper gear position.
10. Will clearing the code fix the P0707 issue?
Clearing the code may temporarily reset the check engine light, but the underlying issue must be addressed to prevent the code from returning.
