4-4-3 Fault Code 850

posted by  someone claiming to be JFarns on  Tue May 17 11:55 CST 2005 [RELATED]

Just checked the codes on our 1995 855 Turbo. Mileage 117K. Using the A2 socket I got a 443 and 435 code. I know what the 435 code is, O2 sensor, but I cannot find the 443 code in my Haynes manual. Anyone know what this means and what the fix is?

Thanks,

JJF

The 443 is "converter efficiency low" and may be just caused by the O2 sensor. Replace the front O2 sensor and clear the codes and see if it comes back.
