Most of the time this will mean that the fuel filter is restricted,or the fuel pump is weak.To check this,you would need a fuel pressure gauge to find out.The o2 sensor is reporting to the ecm this information.

What causes the computer to read bank 1 to lean, bank 2 to lean. It also idles rough and will stall out while stopped. Runs great at operating speeds. It's on a 2004 F150, 4x4, 5.4 vin code 5.


More than likely you have a vaccume leak.Check arround the intake looking for any broken vac.hoses(especally the PCV hose) all the way up to where it connects to the intake.Could be a bad mass airflow sensor, but more likely a vac. leak.

How do I troubleshoot service engine codes for 2002 Ford F-150: PO174 and PO171?


This is the engine lean code. Too much air is entering the engine. Intake manifold gaskets can leak, vacuum lines get old and crack. Check the operation of the EGR and PVC valves, In short it is not easy to find the problem.

Failed OBDII Diagnstic trouble codes P0761 and O1744 What does this mean?


code P0761-
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid 3 valve
- Shift solenoid 3 valve harness or connectors
- Shift solenoid 3 valve circuit is open or shorted
P0761 FORD Description Shift solenoid valve 3 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When is the code detected? The P0761 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off code O1744- is not a code these are the ones I have found that come close

1996 f-150 4wd 6cyl. crank sensor problems


Most of the time this means low fuel pressure,check the fuel filter to see if it is stopped up,if so,replace it,if not,then have the fuel pressure checked to rule out fuel pump.

Yes my truck is 1998 ford f 150 4.2 an i have code po174






DTC code p0174 means "System too lean (Bank 1)"

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exahust). On V6/V8/V10 engines



, Bank 2 is generally the side of the engine that doesn't have cylinder #1.

OBD Code says ''Lean Bank 2 - System too lean


Bank 2 is generally the passanger side. Recently, We have run across a few system to lean codes in Fords. We have ended up changing the O2 sensors.
