OBD-II Code P0907 is a diagnostic trouble code that indicates a problem with the gate select position circuit, specifically signaling a high voltage condition. This code is prevalent in vehicles equipped with manual transmissions, where it plays a crucial role in communicating the gear position of the transmission to the engine control module (PCM).
What Does the P0907 Code Mean?
The P0907 code signifies that the PCM has detected a high voltage reading from the shift lever position sensor. This sensor is responsible for indicating the current gear of the transmission to the PCM. When the signal from the sensor is implausible or outside the expected range, the PCM triggers the P0907 code.
What Causes the P0907 Code?
Several factors can lead to the P0907 code being triggered, including:
- Shift lever assembly failure
- Transmission Control Module (TCM) failure
- Wiring issues related to the shift lever position sensor
What Are the Symptoms of the P0907 Code?
Common symptoms associated with the P0907 code include:
- Check Engine Light illuminated
- Difficulty shifting gears or abnormal transmission behavior
- Transmission may not engage or may slip
How Serious Is the P0907 Code?
The P0907 code is classified as urgent. Ignoring this code can lead to severe transmission problems, potential damage to the vehicle, and safety hazards for the driver and passengers. It is advisable to address this issue promptly.
How to Diagnose the P0907 Code
Diagnosing the P0907 code involves:
- Using an OBD-II scanner to confirm the presence of the P0907 code.
- Inspecting the wiring and connections to the shift lever position sensor for damage or corrosion.
- Testing the shift lever position sensor’s output voltage to ensure it is within the expected range.
- Checking the functionality of the Transmission Control Module.
Common Repairs for the P0907 Code
Repairs for the P0907 code may include:
- Replacing the shift lever position sensor
- Repairing or replacing faulty wiring or connectors
- Replacing the Transmission Control Module if it is found to be defective
How Much Does It Cost to Fix the P0907 Code?
The cost to fix the P0907 code can vary widely depending on the cause of the issue. On average, repairs can range from $100 to $1,000, depending on whether it involves simple wiring repairs or a more complex replacement of the shift lever position sensor or TCM.
Can I Fix the P0907 Code Myself?
If you have experience with automotive repairs, you may be able to diagnose and fix the P0907 code yourself, especially if it involves simple wiring repairs or replacing the shift lever position sensor. However, if you are uncertain or the problem appears to be with the Transmission Control Module, it is recommended to seek professional help to avoid further complications.
