SOURCE: codes p0054 p0141 p0036
code p0054 is
Possible causes - Faulty Heated Oxygen Sensor Bank 1 Sensor 2
- Heated Oxygen Sensor Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Sensor Bank 1 Sensor 2 circuit poor electrical connection
When is the code detected?Heater current requirements too low or high in the heated oxygen sensor (HO2S) heater control circuit Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
code p0141 is O2sensor heater circuit malfunction( bank one sensor 2)
there is chance that wire from that sensor is touching,part of your exhaust system,and either is open or shorting to ground
036 - HO2S Heater Control Circuit Bank 1 sensor 2check the wire from the sensor for the sign cut or melting,and change the sensor

Since you replaced the plugs.. i would go back and check my repair.. Possibly you did something wrong.. like plug wires crossed, loose plugs, you disconnected or bvroke some vac lines or sensors by accident? Look at everything you did very carefully.

Yes there is something in common . Check the fuse # 79 10amp in the underhood fuse box . For O2 sensor , heater power .
The PCM commands the heater ON or OFF to maintain a specific HO2S operating temperature range. The PCM monitors the voltage on the HO2S heater low control circuit for heater fault diagnosis. If the PCM detects that the HO2S heater low control circuit voltage is not within a specified range, DTC P0030 sets for HO2S 1, or DTC P0036 sets for HO2S 2.
So this is not in spec. an it set the other codes !
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0135 sets for HO2S 1
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0141 sets for HO2S 2.
