Ford TSB 03-16-1 says the fix involves several steps: remove the upper manifold plenum and replace the original gaskets and bolts with revised ones, replace the front valve cover with a

The PCM responds by increasing EGR flow, which may keep the EGR valve open longer than usual creating a lean condition in the engine. The MAF sensor can also be contaminated by fuel vapors that back up through the intake manifold and throttle body when the engine is shut off. It consists of clutch drive disc, driven disc, release bearing, clutch fork, cable, slave cylinder, master cylinder. Before a P0171 code is possible, the computer first ran a series of tests to validate the readings from the oxygen sensors.

Thus, a bad sensor may set a P0401 code (insufficient EGR flow), or it may not set an EGR code but a P0171 and/or P0174 lean code instead.

What if There Is No Vacuum Leak or Both Codes (P0171 and P0174) Set?An "under reporting" Mass Air Flow Sensor can be a common cause of a code P0171 and P0174. That's right, these two codes do not identify the oxygen sensors as BAD. In this article, I'm gonna' explore several of the things and conditions that cause a lean condition. Causes 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

You can access it from your iPad or smartphone. Start the engine, let it idle, and then check the Barometric Pressure reading on the scan tool data.

After watching the fuel trim while using brake clean around the intake area we determined the vehicle should have a smoke test. 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.
