0141 is the code it threw. I called jegs and they are sending me a sunfire/cavi sim.
P0141 is for the heater circuit for HO2S-2 (the one AFTER the cat)
What's weird is that you're not setting a P0030 as well for HO2S-1 (pre-cat)
Again I recommend you check/confirm the resistance of the heater portion of the sim (it's a 4 terminal sim I presume??)
The Fail Criteria for this DTC ar as follows:
Heater Current Test
The PCM detects that the HO2S 2 Heater Current parameter is more than 1.5 amps or less than 0.199 amps.
DTC P0141 sets within 115 seconds during the heater current test when the above condition is met.
Heater Resistance Test
The PCM detects that the HO2S 2 heater calculated resistance is not within an expected range at engine start-up.
DTC P0141 sets within 5 seconds during the heater resistance test when the above condition is met.
