    Make sure you have the correct power and ground to the rear O2 sensor heater circuit in your 2005 Acura RSX. Please see the RepairPal article for code po141 - http://repairpal.com/obd-ii-code-p0141.

    I had same code, replaced O2 sensor 1, back sensor was good. Ended up having to replace cat converter, luckily Acura did under warranty.
