Check engine light with no clue..

[Anwar]

Good day all,

My check engine light turned on and I have been searching all over the internet for the past month with no solutions. So I read this list of DTCs off my tuner:
p0030
p0054
p0141
p018c

The car runs perfectly with no weird symptoms. Any one had a similar experience and have any idea what could it be?
I’m not sure if that tells something, I cleared the codes and the first 2 that popped up are P0054 & P018C.


Best,
Anwar

p0030 code: The code means that there is a problem with the heater element circuit of the heated oxygen sensor.

p0054: What the P0054 code means This code means the Heated Oxygen Sensor (HO2S) resistance is out of range with engine bank 1 (side of engine with cylinder #1) on the sensor downstream or behind the catalytic converter.

p0141: A code P0141 may mean that one or more of the following has happened: open or short to ground in the wiring harness; O2 heater circuit wiring high resistance; O2 heater element resistance is high; Internal short or open in the heater element; Note: Typically a failed catalytic converter does not cause this code.

p108c: What Does Code P018C Mean? OBD II fault code P018C is a generic code that is defined as “Fuel pressure sensor “B” – circuit low”, and is set when the PCM (Powertrain Control Module) detects an abnormal signal voltage from the fuel pressure sensor.

Fuel pressure sensor is a known weak point in the EB. The good news is, they're cheap, $30 ish, and super easy to replace. I got a good one from ebay for $20.
