Where is leading sensor on bmw?
\015 THE OBD CODE READER GIVE ME 2 CODES. THE FIRS CODE IS 2850 WHICH IS THE LEADING SENSOR. SECOND CODE IS 2852 WHICH IS REF SENSOR. IS IT EASY TO REPLACE THEM?\015
No code tells you to replace any sensor, it indicates a problem in the circuit or the signal. Do replace any sensors until a trained diagnostic tech has looked into this at the dealer.
