    I just picked up a 96 saturn. The " service engine soon " light came on. So
    I checked it with my auto xray ez link scanner. The trouble code says "
    P0141 O2 sensor Heater Circuit Malfunction ( Bank 1 Sensor 2 ) My Haynes
    Repair Manual says the P0141 fault is "downstream O2 sensor heater or
    circuit fault" The sensor on the exhaust manifold is about $ 90 and the on
    on the catalytic converter is about $180. Are there other checks I can do
    with my scanner to verify which O2 sensor it is? Any help would be
    appreciated. Thanks
