What it means

A signal is arriving from the transmission range sensor, but the computer finds it implausible for the vehicle's condition, such as reading park while the vehicle is moving, or sitting between two positions for too long. The most common cause is a misadjusted sensor or shift cable.

Symptoms4

Check engine light on.
Hard or no cranking in some selector positions.
Gear indicator changing or flickering while driving.
Erratic shifting or the transmission going into limp mode.

Possible causes5

Misadjusted transmission range sensor after installation or transmission service.
Stretched or loose shift cable, so the lever does not fully reach the correct position.
Worn internal contacts in the sensor.
Corrosion or fluid in the sensor connector.
Damage to the shifter base inside the cabin.

How to diagnose5

Watch the selector position reading on a scan tool and compare it with the actual position in each detent.
Check that the reading does not flicker between two positions while the lever is held still.
Inspect the shift cable adjustment and its bushings at the transmission and shifter.
Measure the sensor signals in each position and compare them with the manufacturer table.
Inspect the connector for corrosion or oil or water intrusion.

How to fix5

Adjust the shift cable, or replace it if stretched or damaged.
Readjust the transmission range sensor using the manufacturer procedure.
Clean the connector and repair any corrosion.
Replace the sensor if its reading stays implausible after adjustment.
Clear the codes and confirm the gear indicator matches the lever in every position.

An adjustment or cable repair often solves it at low cost; the cost rises when the sensor or shift cable must be replaced.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions

The code appeared after transmission service. Why?

Usually because the sensor or shift cable was not readjusted precisely after installation, and readjusting them solves many cases.

How is this different from P0705?

P0705 points to a general circuit fault, while this code means a signal is present but does not agree with the vehicle's condition, which suggests misadjustment.
