    hey y'all,
    my check engine light is on and thanks to my dad's handy-dandy actron scanner, i received a P1135 code but have no description for that particular code. ran real-time on it and showed that O2 sensor 2 read 0 voltage. can i deduct that the #2 O2 sensor is bad from this or am i going to have to go to the recall dealer and spend $ for 3 minutes worth of having the right scanner to figure it out?

    thanks in advance,
    wood

    I am no expert but here is what the code says.
    P1135
    Air/Fuel Sensor Heater Circuit Response. (Bank 1 Sensor 1)
    I think it is the closest one to the engine before the CAT. Hope this helps.

    P1135 means a fault with the A/F sensor (aka O2 sensor, bank 1 sensor 1) heater circuit. Possible causes:

    - Open or short in the A/F sensor heater circuit
    - A/F sensor heater fault
    - ECM
