2011年1月13日 · P0154 refers to the right side front (upstream) O2 sensor or wiring if the on board computer is functioning. Presuming that most of us (me) do not have testing equipment. I suggest switching the left front 02 sensor with the right front 02 sensor. All you need is an open end wrench and 15 minutes. Then zero your codes (by disconnecting the battery for about an hour - like I did) then driving ...

2010年12月6日 · About a week later the same circuit tripped another P0154 fault. So thinking I may have a bad circuit I took the O2 sensor I removed from blank 2 and put it in bank 1.

2012年11月12日 · Hello all, I have been getting the check engine light on here lately. been getting code P0174 a few times last week, and today I got P0171 and P0174 which translates to system too lean bank 1 and 2. The engine runs a bit rough at …

2020年7月14日 · Activity on S1 ony starts probably about 2 minutes into a cold engine and then dies about 5minutes later. Just to catch you up.. Fresh rebuild (engine pull and machining), all components same (2 sets of sensors doing same thing - previous ones were basically new also). P0134 and P0154 (both before and after PCM swap), no other codes.

2016年8月29日 · The ECM sends a heater voltage to the O2 sensors to enable them to sense the O2 levels in the exhaust. I would look for blown fuse or broken wire in the harness before or at the connection where it splits to go to all four sensors. With no heater voltage the sensors won't work. Why did you decide to replace the O2 sensors? And why replace just one cat? What problem were you trying to correct ...
