Transmission Range Sensor Rationality Error

on 2002 Volvo S80 2.9L I6 · AWD

What this code means

The transmission range sensor (TRS) reading does not agree with other inputs such as gear state solenoids and output shaft speed.

Symptoms

  • Incorrect gear displayed on dash
  • Transmission may not shift out of park

  • Wrong gear engagement
  • Intermittent no-start in Park

Common causes

  • TRS misadjusted
  • TRS internal failure
  • Shift linkage loose or worn
  • TRS connector corroded
  • TRS wiring short

Diagnostic steps

  1. Compare TRS signal to actual gear selector position
  2. Inspect shift linkage adjustment
  3. Test TRS voltage in each gear position
  4. Check TRS connector
  5. Monitor TRS signal for dropouts

Repair notes

Adjust or replace transmission range sensor. Check and adjust shift linkage. Verify correct gear display in all selector positions.
