I am receiving p0132 and p0138 OBD2 codes on my vehicle. While investigating I found that the O2 sensor relays on the distribution box are missing, further more I found that the relay compartment is not having any terminals to hold and connect the relay in the distribution box, located under the hood above the right wheel just beside the battery. I have new O2 sensors but before installing I want to make sure; if I need those relays in place or are they located some where else. Would the O2 sensors work without those relays?
