Common questions

What does transmission range sensor Circuit High input mean?

What does transmission range sensor Circuit High input mean?

The presence of a P0708 diagnostic trouble code means that the transmission range sensor / neutral safety switch is sending the wrong signals back to the ECM.

What does the p0708 transmission range sensor do?

The PCM or TCM uses the transmission range sensor, also called the inhibitor switch, to determine the position of the shift lever. If it receives signals that indicate two different gear positions at the same time for more than 30 seconds P0708 will be set.

What causes transmission range sensor to set high?

Potential causes for this code to set are: The transmission range sensor receives a twelve volt signal from the ignition switch and sends a signal back to the PCM/TCM that is appropriate for the selected position of the gear shifter.

What kind of switch has a transmission range sensor?

In terms of its operating principles, the transmission range sensor is typically a rotary type switch similar to an ignition switch in which different circuits are completed depending on the position of the moving part (s) in the switch.

What does the OBD II fault code p0708 mean?

What Does Code P0708 Mean? OBD II fault code P0708 is a generic code that is defined as “Transmission range (TR) sensor/switch -high input’, and is set when the PCM (Powertrain Control Module) detects an input voltage from the transmission range sensor and/or its control/signal circuit (s) that exceeds a maximum allowable threshold or limit.

What is the diagnostic code for transmission range sensor high input?

P0708 is a diagnostic trouble code (DTC) for “Transmission Range Sensor Circuit High Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
