ford explorer error code p0174 Pinecrest, California

When you are behind a car or truck that is misfiring it makes your eyes burn. The DPFE sensor is mounted on the engine, and is attached with two rubber hoses to the tube that routes exhaust gas to the EGR valve. The MAF sensor is located in the air inlet tube just ahead of the throttle body. Do you need more help with the P0174 Ford code?

Since 1996 we have been the #1 Ford Explorer resource on the Internet. Click the banner below to Ask an Expert: Need more Information about Ford Lean Codes or Other Fault Codes? Code P0171 applies to Bank 1 and P0174 applies to Bank 2. If your engine has a fuel delivery problem, the fuel trim values will become more positive as engine speed and load increase.

Almost like it is starving for fuel. Share NOTE: This information is presented for information purposes only. If the problem persists the front oxygen (O2) sensor may need to be replaced.It's a very common problem for the Ford Windstar. Dirt can stick to the MAF sensor wire and form a coating that slows the response of the sensor to changes in airflow.

When the air ratio goes below 14.7 parts, this is called a "rich" mixture.

You may be wondering where bank 1 and bank 2 are located on the 4.0L Ford V6, well, using the illustration in the image viewer as a guide: Bank 1 is 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 The computer tried to compensate, but since resolution is impossible, it sets the code. Some of the high performance 4-cylinder and straight 6-cylinder engines (such as those in BMW and Lexus) split the cylinders into groups of two or three and call them separate banks.

The vacuum leak may be real or it may be a “perceived vacuum leak” caused by some failed sensor. Hook up your scan tool, go to the PID data menu and look at the fuel pressure PID. For example: if the intake manifold gasket is bad and creating a vacuum leak... If it is a V6 or V8 engine and the code is only on one side/bank, it could be a defective Intake Manifold Gasket or cracked/leaking manifold.

The underlying cause might be a weak fuel pump, low voltage to the fuel pump (which prevents the fuel pump from spinning fast enough to deliver normal fuel flow), a restricted If you still can't find the problem, be sure to check and verify that fuel pressure and delivery are at spec. On Ford some models dirty air filter, and dirty or faulty air flow sensor are the cause of the problem.It's a very common problem for the Ford Windstar. 1999-2003 Fords Windstar One of the biggest misconceptions, about these two diagnostic trouble codes, is that they accuse the oxygen sensors as being BAD...

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time. Before we get into the main causes of P0171, let's explore why this code matters. Essentially, this means that the Air Flow Sensor is telling the computer that much less air is entering the engine than actually is. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.

When the car was driven a... On 3.8L Fords with a split-plenum intake manifold, the port gaskets and isolator bolt assemblies for the upper plenum can deteriorate over time and leak air, often as a result of A dirty MAF sensor can set a lean code. This causes the MAF sensor to under report airflow, which in turn misleads the powertrain control module (PCM) so it doesn't add enough fuel to maintain a properly balanced air/fuel ratio.

I replaced plug, cop, and the injector. Disconnect the air inlet tube just ahead of the sensor, and then spray the electronics cleaner through the screen at the wire element in the center of the little MAF sensor.

The vacuum leak may be real or it may be a “perceived vacuum leak” caused by some failed sensor. Possible Solutions Possible solutions include: In the vast majority of cases, simply cleaning the MAF sensor does the trick. Tech notes The codes is usually set when there is an intake leak after the air flow meter, before replacing any parts check for loose or broken hoses and intake gasket Do not use any other type of cleaner as this may damage the sensor.

If the air rises above 14.7 parts, it is called a "lean" mixture.Rich Mixture = Too much fuel, not enough airLean Mixture = Too much air, not enough fuelTo keep the Since the oxygen sensors passed their readiness tests and didn't set any codes, the computer then looked to the Fuel Trim adjustment. This bank is the one on the driver side of the engine. WHAT A LEAN CODE MEANS A lean fuel condition may exist if the engine is sucking in too much air and/or the fuel system is not delivering enough fuel.

Symptoms 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.
