oxygen sensor
You have a bad o2 sensor (low voltage)
it depends on the model of engine, my 97 rodeo with the 4ze1 motor has the map sensor for air intake but doesnt have an O2 sensor for the exhaust.
the o2 sensors are located on the exhaust pipe one by trans and one by the muffler there is 2 of them
its on the end of the wires just above the air filter housing unit
the bank 2 is on the driver side i got this info from an Isuzu mechanic
Right next to the oil filter
i have just gone through this same situation, in my case it follows with i think 1157 or 1137 regardless they are o2 sensor codes. funny enough this , in my case, led to the MAP sensor found center rear of intake manifold. worked for me 100 CAD new pop it out and replace it should be good as new! Good luck
Bank 1 is the side that cylinder 1 is on, sensor 1 is downstream and sensor 2 is upstream
Truck has 4 sensors 2 pre 2 post catalytic. Which one do you need 7/8 wrench or o2 sensor socket to replace What fault code is set/ I can tell you which one you need if you tell me the code
Mine has 4 O2 sensors, one before, and one after the CAT on each bank. (just a FYI, I was getting an O2 lean error caused by the short flex pipe just after the Y leaking)
Downstream O2 sensor circuit volts high.Downstream O2 sensor circuit volts high.
if you go to a part store to get the O2 sensor you could actually ask them to give you a diagram or directions how to change them KKODAL
