2000 Ford Taurus SES Check Engine Light: P0174 and B1600 Codes Explained
My 2000 Ford Taurus SES has the check engine light and oil light on. I took it to AutoZone, where they scanned the vehicle and found two diagnostic codes: P0174 and B1600. The P0174 code relates to the air-fuel ratio in the exhaust system, specifically indicating a lean condition in cylinder 4 or later cylinders. The B1600 code is associated with the anti-theft system (PATS), suggesting an issue with key recognition. I'm not sure if this affects vehicle operation—could it be disabling the engine or preventing start-up? Additionally, the oil light is on; I'm concerned about potential low oil pressure. Any insights or troubleshooting steps for these codes would be greatly appreciated.

If your vehicle has a remote starter, it may be disabled due to this issue—this should be checked and resolved. Regarding the oil light: if it's illuminated, check the engine oil pressure. Low oil pressure can lead to serious engine damage and should be addressed immediately.
