What does Ford code 92 mean?

Shift solenoid 2 circuit failure or oxygen sensor indicates rich

Common causes of 92

  • The shift solenoid 2 circuit is open or damaged.
  • Shift solenoid 2 itself failed.
  • A blocked intake or a leaky injector drives the system rich.
  • High fuel pressure overfuels the engine and the HO2S reads rich.
  • The PCM cannot command shift solenoid 2.

How to fix 92

  1. Check the wiring and connector at shift solenoid 2 in the transmission.
  2. Test shift solenoid 2 and replace it only if it fails its own test.
  3. Check the intake for a blockage and the injectors for a leaking one.
  4. Measure fuel pressure and compare it with spec, since the rich half of this code reads high.
  5. Test the PCM last, only after every circuit test has passed.
  6. Clear the code, then retest to confirm the shift and the mixture are correct.
