P0853 Drive Switch Input Circuit

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

The drive switch input reports to the engine or gearbox module that range D is selected, usually through its own contact in the range switch or selector next to the park/neutral contact. No maker documents these codes; GM's tables up to 2025, Ford's summaries and Saab service data were searched. The description follows California's rule for inputs, circuit and plausibility checks, and the documented park/neutral input, which is checked against the gearbox module's range. P0853 is the general circuit or plausibility fault without telling low from high.

Likely causes

Range switch or D contact faulty or misadjusted
Wire or connector open or corroded
Selector cable misadjusted
Module input or software

Symptoms

  • Fault stored, MIL depending on maker
  • Gear indicator wrong
  • Cruise control not working
  • Gearbox emergency program possible
