1999 Ford Explorer XLT 4.0 SOHC 4x4 code P1151 bank 1


Ok this is either a shorted wire or bad connector or just plain a bad 02 sensor or a stuck injector or bad PCV needs cleaned. You stated it runs great i would go with Bad 02 sensor first or check for possible exhaust leak and last check for bad converter.

Is the wiring good going to the O2 sensors? Maybe just look the car over and see if you have any bad grounds. They can do weird things. Could be a bad ICU.

Running lean on bank 1 and bank 2 codes 171 174 runs great when codes are off once they come on loss of power not much but you can feel it


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.

Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.

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.


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 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


Hope helps.

P1507 P0171 & P0174 error codes on 02 windstar


p0171 indicates the system is running lean on bank 1,p0174 means the system is running to lean on bank 2 p1507 is an idle speed under run fault i'd suspect an air leak is the cause of your problem check air intake system for airleaks
