Question about 1998 Jeep Grand Cherokee
I need to replace both o2 sensors I need to locate both of them and discover the best way to replace both of them by myself
we can not answer what you can do, skills. tools????
but first you might tell which engine is in the car.
what does need mean? got DTCs, or just what?
the 02 sensor come in 2 3 or 4 each. (each) or if Calif car. looking and counting helps. the i6- can have just,2 one front one rear,
depends on which engine you have. 4l or 5.2L?
i you just take 5min open hood and look the exhaust headers.
and look, from there to rear the the CAT/CATS, youd see them all.
in 5min flat. this works on all cars, made, USA.
they look like shinny steel (SST) spark plugs with 4 wires each. and matching connectors. you can google 02 sensor and see 10million posts on what they look like.
your car is ZJ, jeep.
and read the exhuust section of the FSM.
you unscrew them, unplug them.
and put them back.
it's literally that easy if not too rusted.
read cars for dummies book, first. an then ask questions.
Bosch sells PNP sensors (they just pulg in and play)
the bosch.com web site has and ecatalog. use it to get the right
02 sensors. for USA fed or USA calif. car.....

If you still have a cap rotor and ignition wires, it's inside the distributor. If not, it is the part where the distributor used to be (center rear of the engine behind the intake manifold)

pic REMOVAL - 4.7L
The Camshaft Position Sensor (CMP) on the 4.7L V–8 engine is bolted to the front/top of the right cylinder head (CMP Location—4.7L Engine).
It is easier to remove/install sensor from under vehicle.
Raise and support vehicle.
Disconnect electrical connector at CMP sensor (CMP Location—4.7L Engine).
Remove sensor mounting bolt (CMP Location—4.7L Engine).
Carefully twist sensor from cylinder head.
Check condition of sensor o-ring.
See picture for sensor location.
