SOURCE: Ford Windstar 1996 Trouble Codes P0171, P0141, P0161, and P0174

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

oxygen sensors are telling you that the mixture is too poor on ur sistem need to check its behaviour and see whats causing that lean mixture
hoope this helps

It means that bank 2 is not getting enough fuel from the fuel injection system. try running some injector cleaner through your vehicle

Trouble code p0154


code p0154 refers to heated oxygen sensor (HO2S) 1 bank 2 -- no activity detected===causes --wiring---HO2S---= ECM
it also refers to oxygen sensor (O2S) --no activity detected--===causes --- wiring---O2S sensor---ECM. May be you did not replace the sensors causing the fault.

Po174 and po154 what is possible solutions


P0154 - 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)
The oxygen sensors are critical to the engine running properly. It basically informs the PCM (Powertrain Control Module) of oxygen content of the exhaust. The PCM then uses this information to regulate fuel into the engine and maintain proper air:fuel ratio. It is a four wire sensor, with the PCM providing a reference/signal voltage of about half a volt (0.5v) to the sensor. It usually provides a ground also. The other two wires are dedicated to the oxygen sensor heater element. This heater allows the sensor to warm up faster, which allows the engine to enter closed loop faster, reducing startup emissions. The heater element is supplied a 12v feed from the power distribution center (usually) and a ground.

The oxygen content of the exhaust affects the O2 sensor resistance. This resistance produces a counter voltage on the reference/signal wire that the PCM will use to analyze oxygen in the exhaust. Lean exhaust produces low voltage, while rich exhaust produces high voltage. The oxygen sensor is capable of varying between 0.9v (rich) and 0.1v (lean). Once the engine reaches closed loop, the O2 sensor should begin switching rapidly between rich and lean voltages 2-3 times per second. If for some reason the O2 sensor doesn't switch properly or "sticks", P0154 may set. This code indicates the O2 sensor isn't operating.


P0174 - System Too Lean (Bank 2)
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.


If need additional details, just contact us. Hope this helps.

How do i repair code p0154


P0154 definition 02 (Oxygen sensor) circuit no activity detected bank 2 sensor 1, You need to test the heater circuit for its 12 volts and test the ground, its basically a dead 02 sensor,If you have a misfire you would have code as lean activivty, basically there is no lean to rich activity for this code to come on

Code p0154


P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)

Check for the following:
1. A poor connection or damaged wiring harness. Inspect the harness connectors for :

Backed out terminals
Improperly formed or damaged terminals
Poor terminal to wire connection
Damaged harness

2. A malfunctioning HO2S heater on heater circuit
