Possible causes- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

Codes PO141,PO403 on Olds Intrigue 1998


PO141--Oxygen Sensor Heater Malfunction (Bank 1 Sensor 2)

I would change all the O2 Sensors,when a monitor or downstream
fails,which they seldom do

PO403--EGR Circuit Malfunction

Codes Related---NO

Converter- if it is 14 years old, it is done working very well,
but not related to the heater in the oxygen sensor

I would do all the O2's,the converters & EGR Valve & go from there

I never give out that info,but look how old the car is,it won't pass
inspection, with just one of those three issues

Code P0102 shows up indicates Mass Air Flow Sensor. 1998 Olds Intrigue. It is like it has the hiccups and dies when slowing down and coming to a stop. Is replacing the Mass Air Flow Sensor likely going to...


Try this first. You can buy some MAF cleaner( not carb cleaner) and try to clean it off. Let it dry completely and don't probe the sensor with anything but spray from the cleaner. Change the air filter with a quality filter; the cheaper ones leave deposits on the sensor.

How to repair odb2 code p0171


P0171 means that an oxygen sensor in bank 1 detected a lean condition meaning there is to much oxygen in the exhaust. Bank 1 is the front side of the engine. There's other things that can trigger that p0171 code like the MAF (Mass Air Flow) Sensor which could be dirty or faulty. There could be a vacuum leak downstream of the MAF sensor.

Before you try to replace that MAF sensor, take it off and clean it which a Brake cleaner. Try not to damage the sensor and make sure to clean it dry before putting it back in. The MAF sensor is located on the throttle body. It looks like this (They are small and expensive, try cleaning it first before buying a brand new one, not a remade [the cheaper one]):

Inspect all vacuum and PCV hoses, replace if they look bad. Check for a dirty fuel filter and proper fuel pressure then it should be back up and running good.

Code


Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust).

A code P0171 may mean that one or more of the following has happened:
The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters (K&N, etc.) can cause the MAF to become dirty if the filter is over-oiled

There could be a vacuum leak downstream of the MAF sensor.

You need to clean your MAF (most likely) use brake cleaner or something like it. Just spray the ***** down.

Hope helped (remember rated this and comment this help).

Ford windstar check engine light comes on after stopping when starting to get moving again shows p0171 & p0174 codes why??


P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks. P0174 OBD-II Trouble Code


Technical Description

System Too Lean (Bank 2)


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.

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

P0171 - System Too Lean (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

A code P0171 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.
Possible solutions include:
  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure

P0174 is identical to P0171, except it indicates the problem exists on Bank 2 as well.

I have a 1999 oldsmobile intrigue that is misting a lot. It idels rough, and runs rough. I can still take off it is a little slow, but I can still go pretty fast, but it still mist at the high speeds...


fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck
