Hello all,

I’ve been troubleshooting a P0135 code for the past week and have not found a solution yet. I replaced the upstream O2 twice now and checked the fuses and they are both fine. I also checked the wiring harness on the ECU as well as the primary O2. Now all that’s left is replacing the relay for the A/F Sensor. Posted below is the location of the relay but mine is missing. I never had a CEL before so I’m uncertain why this missing relay has never been an issue until now. But I’ve looked everywhere and have yet to find the missing relay. Maybe there is a universal one I can put in but I don’t know which relay would fit in that slot.
