B1 S2 lambda sensor

Featured Replies

Fabia 1.4 MPI Drives fine but occasional suggestion of a misfire when accelerating hard.

 

Codes showing.

 

16825 - EVAP Emission Control Sys
            P0441 - 35-00 - Incorrect Flow
17526 - Oxygen (Lambda) Sensor Heating; B1 S2
            P1118 - 35-00 - Open Circuit
16524 - Oxygen (Lambda) Sensor B1 S2
            P0140 - 35-10 - No Activity - Intermittent

 

Sounds like a duff S2 lambda sensor? Connecting heater wires up to a 12v source doesn't seem to heat it up. Does the heater  use 12v?

 

16825 - Would that be the N115 purge cannister solenoid being unhappy or is some other fault more common?
