Ford 92 Shift solenoid 2 circuit failure or oxygen sensor indicates rich
How to read it
Code 92 reads as 9 flashes, pause, 2 flashes on the check-engine light. Jumper the self-test input to signal return at the test connector, then run the key on engine off self test and the running self test, counting the check-engine flashes each time.
New to flash codes? The How to Read Ford EEC-IV Self-Test Codes walks through the test and what the numbers mean. The general OBD-I guide covers the rest.
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
- Check the wiring and connector at shift solenoid 2 in the transmission.
- Test shift solenoid 2 and replace it only if it fails its own test.
- Check the intake for a blockage and the injectors for a leaking one.
- Measure fuel pressure and compare it with spec, since the rich half of this code reads high.
- Test the PCM last, only after every circuit test has passed.
- Clear the code, then retest to confirm the shift and the mixture are correct.
