Default Code P0160
I just got this code yesterday, is it front or rear O2s? I have LT headers, no cats with rear o2 simms.

Make sure you don't have a loose connection at the sim. But it's quite possible that your o2 sim is no longer tricking the PCM.

If the problem is not a loose connection, then your best bet is to have someone remove this diagnostic from the PCM, or I suppose you could try another o2 simulator.

Try doing a search, this is a common problem.

It's the passenger side rear O2 sensor.

This means your O2 simulators aren't doing their job. You could pull the PCM BATT and PCM IGN fuses from under the hood and let the car sit for about 10 minutes to get rid of the SES code, hopefully it won't come back on.
