Question Regarding 02 sensors
Hey Guys,
Im currently getting the following o2 sensor codes (soft code) (2CA7 & 2CAB) which are o2 sensor heater & o2 sensor temperature (both before cats, bank 2.) I was under the understanding that a bad heater on the 02 sensor would not affect the AFR's, but last night i was logging my car and noticed my fuel pressure really low & boost way off target. Can a bad o2 cause the engine to pull back on these things without any hard codes ? |
