Since we are on the subject of O2 sensors, I recently wired in my O2 sim in the last month. It has been wired in correctly, however the SES light is still on. Ran faults, and the sims have indeed eliminated the cat deficiency codes, but now I am running codes for post O2 sensor heater circuit malfunction.

Has anyone ran into this problem wiring in their o2 sims? Does anyone maybe have a solution to simulate the heater circuit in a similar fashion to how the post sensors are simulated to complete the circuit and turn off the SES light?

Anyone know the resistance on the heater wires?
