I have a 2004 Chrysler Pacifica - 136266353That would be your HO2 sensor. It's located in the left hand exhaust manifold closer to the top of the engine. It usually takes a special socket to remove one. If you have any doubt, take it to a shop and have them replace it for you. This sensor effects fuel and driveability, don't go to long without fixing it as it may cause damage to your catalytic convertors.

Its not a P0300 it's P0032 and P0038

code p0032refers to heated oxygen sensor(HO2S) 1 bank 1-heater control--circuit high===causes --wiring short to positive--HO2S sensor--ECM
code p0038 refers to heated oxygen sensor(HO2S) 2 bank1 heater control --circuit high===causes --wiring shorted to positive --HO2S---ECM
It is most important that when installing /removing the sensor that the correct tool is used to prevent damage to the wiring for the sensors. Severely twisting the wires during installation/ removal will result in the causes for failure listed.

I have a 2004 Chrysler Pacifica and need to change the O2 sensors. These are the OBD codes I am getting when my check engine light came on. P2096 P0137. What I am trying to figure out is which is bank 1 on...

bank 1 cyl 1 if 02 sensor fault is present replace both sensors with oe part as sometimes after market sensors may not be compatible.both sensors because 1 will be week and will cause the same failure later provided the cat is ok and does not store a cat efficiency fault.

These are the codes i got p0030, p0053,p0302,p0053, p0054,p0134


Code explanations as follows:

P0030 = HO2S Heater Control Circuit (Bank 1 Sensor 1)
P0053 = HO2S Heater Resistance (Bank 1, Sensor 1)
P0054 = HO2S Heater Resistance (Bank 1, Sensor 2)
P0134 = 02 Sensor Circuit No Activity Detected (Bank 1, Sensor 1)
P0302 = Cylinder 2 Misfire Detected
