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.

What does Ford code 92 mean?

92. Shift solenoid 2 circuit failure or oxygen sensor indicates rich. This code sets when your vehicle computer detects shift solenoid 2 circuit failure or oxygen sensor indicates rich.

Common causes of 92

• Intake blocked
• Excessive fuel in engine oil
• Fuel pressure high
• Breather system
• Injectors
• HO2S
• AIR system
• EVAP system
• MAF/MAP sensor
• Ignition system
• ECM

How to fix 92

1. Check the intake for a blockage
2. Check for excessive fuel in engine oil
3. Measure fuel pressure and compare it with the spec: this fault reads high
4. Check the breather system for a blockage
5. Check the injectors for a clogged or a leaking one
6. Test the HO2S and replace it only if it fails its own test
7. Check the AIR system for a stuck valve, a blocked passage or a dead pump
8. Check the EVAP system for a leak or a stuck valve
9. Test the MAF/MAP sensor and replace it only if it fails its own test
10. Check for ignition system
11. Test the ECM last, only after every circuit test has passed
12. Clear the code, then retest to confirm the fix holds
