check engine light logo

P0707 code definition

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.

What the P0707 code means

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.

What causes the P0707 code?

  • Transmission range sensor has failed
  • Open or short in the wiring harness
  • Park/neutral position switch has failed
  • Poor electrical connection
  • Misadjusted transmission park/neutral position switch

What are the symptoms of the P0707 code?

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.

How does a mechanic diagnose the P0707 code?

  • Uses a scan tool to check for any codes current, history, or pending
  • Notes the freeze frame data from each code
  • Clears the codes
  • Takes the vehicle on a test drive to confirm the fault
  • Performs a visual inspection for any misaligned shifter linkages, worn or broken wiring, damaged components, and transmission fluid level/condition
  • Uses a scan tool to monitor the operation of the transmission range sensor
  • Uses a multimeter to check the voltage of the transmission range sensor

Common mistakes when diagnosing the P0707 code

  • 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

How serious is the P0707 code?

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.

What repairs can fix the P0707 code?

  • Replacing the transmission fluid
  • Replacing the transmission range switch
  • Repairing an open or short in the wiring harness or replacing it
  • Repairing or replacing the park/neutral position switch
  • Repairing or replacing broken electrical connections

Additional comments for consideration regarding the P0707 code

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.
