If you hear air in the engine, there must be a leak somewhere.
Check all the vaccum hoses for bad ones or dissconnected ones. All it takes is a pin hole in these darn emission systems to screw up the whole system.
It could also be a leaking intake manifold gasket.

SOURCE: 2001 ford explorer sport, door keypad reset

How to find the Security Keyless Keypad Code on the 1995-2001 Ford Explorer or Mountaineer and how to use the Keypad functions. The factory code is also printed on a label which is installed on the Remote Anti-theft Personality (RAP) Module. This is the module that controls the keyless entry system. It is located in the left rear quarter behind the removable panel (see photo). You will need to turn the two thumb screws counter clockwise and take the plastic panel off to be able to see the unit. A flashlight may be helpful in seeing the code. You are looking for the module and the 5 digit code on it like the one shown below.

Now that you’ve got the code I’ll tell you how to use the Keyless entry and set-up your own code.Make sure when pressing the controls on the keyless entry keypad you press the middle of the buttons to ensure good contact with the controls.

Check this for Programing the Keypad.

Hope this help (remember rated this comment).

SOURCE: 1998 Ford Taurus SE---171,000 KLM..... code P0 171

hi, this code refers to an engine fuel mapping strategy designed to monitor air flow going into the engine and exhaust flow out of the engine to prevent any vacuum leaks, rich fuel conditions, or clogged/open air induction systems that will cause failure of emissions control or catalyst failure. the pcm monitors long term and short term fuel trim to compensate for rich or lean combustion. if the long term fuel trim reaches limits of 15 percent adaptation either positive or negative, the codes p0171, p0172,p0173, p0174 and p0175 will be set depending on which condition is happening. generally, p0171 tells of extra lean combustion occuring on bank one(on your vehicle, it will be the half of the engine that is furthest towards the front of the engine block, where cylinder one is located, i think the rear bank of your engine) okay, look for air tube cracks and leaks btween the mass air flow sensor and the throttle body, look for spongy vacuum hoses that close under vacuum, look for obvious vacuum leaks, check the evap purge control solenoid hose, commonly leaking here, also check pcv valves to make sure they are not blow out. if all tests okay, next step is to check the intake manifold for vacuum leaks, cracks in the gasket, etc. if okay here, check fuel pressure, maybe clogged fuel filter causing low flow, clogged fuel injectors, and bad fuel pressure regulators can occur. if all checks out okay, check the mass air flow sensor by removing from housing and physically looking at the intake air side(the side that recieves air from the filter) for dirt and contaminates. you can check this first if you like, also common problem. ford does not recommend to clean this sensor, only replace if contaminated. but you can try to clean with brake clean just as a test to see if it helps, just don't overdue the amount of cleaner, little goes a long way. if all this tests and looks good, go see a ford dealer! the last step of the diagnostic strategy is the test pcm(engine computer), don't do it yourself, take it the dealer. good luck!

Why do you get code p0171,p0174/


Code 171 means the fuel mixture is too lean on bank one and code 174 is the same thing for bank two. So I doubt the O2 sensors are faulty. Chances are you have a fuel problem, maybe low fuel pressure.

2002 ford windstar engine lean bank 1 and lean bank 2


Google your codes & then diagnose the
system & items related to the codes

Type: OBD Code PO 171 --or whatever the codes are

If you have Oxygen Sensor Codes, it is most likely the upstream sensors have failed, because you did not know they get replaced as preventative maintenance at 100,000 or when they fail, if that is how you take car of your vehicles

We have a 2001 ford explorer sport. Won't pass


The error code 1131 means the air/fuel mixture is too lean on Bank-1 while 1151 indicated mixture is lean on Bank-2. You can check for the causes of the problem in following link for both error codes (1131 as well as 1151):

Code 2195 on ford sport trac 03


PO114 Intake AirTemp Sensor 1 Intermittent/Erratic
PO128 Coolant Thermostat Temp Below etc etc
PO135 HO2S Sensor Circuit Malfunction HO2S-11 That's right bank front
PO171 lean #1
PO174 lean #2
P2195 lean #1
P2197 lean #2
P2198 rich#2

300 & 316 just misfires forget them

You can find all those on internet

Diagnose & replace all bad COP Ignition Coils --- problem gone

Replace front oxygen sensors on all your vehicles at 100,000 miles
That is required preventative maintenance, unless you don't care about
fuel trim & throttle response

I didn't go into details with the codes-- too much too type

I doubt you can work on it

If you want the long version & do it yourself -- I'll give you that later tonight

Just ask what you want
going to need a good amount of basic vehicle knowledge though

What are 171 and 174 code on maintaince


Both are lean indicators. You probably have a vacuum leak from either bad injector o-rings, or leaky intake gasket, or a cracked vacuum line.

2001 E250 4.2 codes po 171 174 172 175


P171 Lean to bank one
P172 Rich to bank one
P174 Lean to bank two
P175 Rich to bank two.

These are conflicting codes. I would suspect that you have a bad MAF sensor. take it out and try and clean it before you replace it. It could also be a bad O2 sensor. But unlikely that both sides went bad at the same time.

Check engine light on computer codes 171 174 171-HEGO sensor unable of snitch cylinder bank #1 fuel system at adaptive limit (1990 on) code 174 hego sensor snitching too slow, cylinder bank #1 (1990)


switch, we run off snitches. 171 174 banks 1 & 2 Lean. Most likely cause are Upper Intake Manifold Gaskets, failed seals. It's not 1990 on. It's 1996 and on OBD2.
