This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble understanding what gear the car is in. It's like when you can't tell if a light switch is on or off.
The transmission range sensor tells the car's computer what gear the transmission is in. If the signal from this sensor is out of range or not performing as expected, the computer sets this code.
The Transmission Range Sensor (TRS) is responsible for indicating the current gear selection to the vehicle's Powertrain Control Module (PCM). When the PCM detects a signal from the TRS that is inconsistent with the expected range or performance, it triggers the P0706 code.
• Check Engine Light is on
• Vehicle may not start
• Transmission may not shift properly
• Faulty transmission range sensor
• Damaged or corroded wiring/connectors
• Misadjusted transmission range sensor
Transmission Range Sensor: A sensor that tells the car's computer what gear the transmission is in.
PCM: Powertrain Control Module, the car's main computer for engine and transmission management.
• Use an OBD-II scanner to verify the code
• Inspect the transmission range sensor and its wiring
• Check for proper alignment and adjustment of the sensor
• Replace the faulty transmission range sensor
• Repair or replace damaged wiring/connectors
• Adjust the transmission range sensor
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Honda Accord
• Regularly inspect transmission components
• Ensure sensor connections are clean and secure
• Follow scheduled maintenance for transmission
Sensor Issue
• Avoid driving the vehicle until repaired to prevent further damage
• Consult a professional mechanic for accurate diagnosis
Check with your vehicle manufacturer for specific warranty coverage on transmission components.
This code has been associated with transmission sensor issues in various vehicles over the years, often due to wear and tear.
Moderate – It should be addressed soon to avoid potential transmission damage.
Ignoring this issue may lead to unsafe driving conditions and potential transmission damage.
• Vehicle in park or neutral
• Engine running
The transmission range sensor is typically located on the transmission housing, near the gear selector linkage.
Q: Can I drive with a P0706 code?
A: It's not recommended as it may lead to further transmission issues.
Q: How do I reset the P0706 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
