P0707 is a generic OBD2 trouble code that points to a fault within the transmission range sensor. This code may be seen with various other transmission codes.
The P0707 diagnostic trouble code means the transmission range sensor circuit has low voltage input. The ECU looks for a specific range of voltage in the transmission range sensor and when the voltage input is low the ECU sets a Check Engine Light on the dashboard.
There can be a wide range of symptoms found with the P0707 code. Some vehicles may only exhibit the Check Engine Light on the dashboard. Other vehicles may experience problems like not being able to shift properly, not being able start, or a decrease in fuel economy.
Not checking and overlooking simple causes such as dirty transmission fluid or misadjusted position sensor, and replacing components that are working properly
Not following steps in the right order and not completing all steps that need to be completed for an accurate diagnosis
P0707 can cause the vehicle not to start due to the ECU thinking the transmission is in the wrong gear. In other cases the vehicle may run fine but wont shift properly. Both of these cases should be repaired as soon as possible to avoid further issues.
The transmission range switch is generally inside the transmission Park / Neutral position switch. These parts are usually replaced as a unit as they are not sold separately. The park neutral switch is used by the ECU to make sure the vehicle is in a safe gear before it will allow the vehicle to start.
An advanced level scan tool is extremely useful when diagnosing the P0707 code. Scan tools such as these allow technicians to view information that is critical to determine which components are working properly.
