P0708 Code Definition

Transmission Range Sensor Circuit High Input

What the P0708 code means

The P0708 trouble code means that the Engine Control Module (ECM) has detected a malfunction with the transmission range sensor.

What are the causes of the P0708 code?

  • A misadjusted transmission range sensor
  • A faulty transmission range sensor
  • Damaged or disconnected wiring that is associated with the transmission range sensor
  • A faulty ECM

What are the symptoms of the P0708 code?

  • Hard shifting
  • Transmission slippage
  • Transmission will not shift at all
  • Check Engine Light illumination

How does a mechanic diagnose the P0708 code?

A mechanic would begin the diagnosis of the P0708 trouble code by finding the manufacturer’s suggested procedure for adjustment of the transmission range sensor and attempt to correct its adjustment. If an adjustment does not resolve the issue, the mechanic would then test the transmission range sensor per the manufacturer’s recommendations.

If the sensor or any wiring in the circuit is found to be defective during diagnosis, replacement of these parts would be required to resolve this issue. If all of these parts are in good working order, it is possible that the ECM is at fault.

Common mistakes when diagnosing the P0708 code

A common mistake would be to replace the transmission range sensor without checking to see if the manufacturer has specified an adjustment for it. If the transmission sensor is possible to adjust, the adjustment may resolve the issue.

How serious is the P0708 code?

I would consider the P0708 trouble code to be very serious. This not only causes drivability issues, but it also risks serious damage to the transmission.

Some vehicles have a fail-safe mode that it may go into when this code is stored that will limit engine power and vehicle speed in order to help prevent or reduce transmission damage.

It would be best to have this trouble code diagnosed and repaired as soon as possible.

What repairs can fix the P0708 code?

  • Adjusting the transmission range sensor
  • Replacing the transmission range sensor
  • Repairing or replacing wiring that is associated with the transmission range sensor
  • Replacing the ECM

Additional comments regarding the P0708 code?

It is important to keep up on transmission maintenance as doing so may prevent trouble codes such as the P0708, as well as internal transmission damage. Having services such as a transmission flush and filter replacement at the recommended intervals can drastically improve the life of your transmission and all of its electronics.
