Hi
I have a yellow check engine light and an OBD2 scanner gives me the following errors:-
P0132 [0x0132]
Heated oxygen sensor (HO2S) 1, bank 1 - high voltage
HO2S Circuit High Voltage Bank 1 Sensor 1
Status: Confirmed
----------------------------
P0133 [0x0133]
Heated oxygen sensor (HO2S) 1, bank 1 - slow response
HO2S Slow Response Bank 1 Sensor 1
Status: Pending
I have taken the one lambda sensor (VWAG 03E 906 262 C 12V) that has easy access on the top of the engine, as I thought this would be bank 1, and tested the heating element with a multimeter.
It reports 4 ohms, the replacements I found online state 6 ohms.
So is this sensor faulty or is 4 ohms within the operating range?
Thanks
