99 Ford F150, OBD II Code, P1151?
Bran new to this board, my apologies if this question has already been beaten to death. I did a search an did not find any info on this.
My question is I have a 99 F150, check engine light came on, went to Advanced Auto and they plugged their scanner into my OBD II plug and they say the code is a "P1151 Manufacturer Control Fuel Air Metering". After doing some goggling, I found that it also is: "Bank1, Long Term Fuel Trim, Range 1 Leanness Lower Limit Exceeded" ???
Other research said:
A code P1151 may mean that one or more of the following has happened:
Short to VPWR in the harness or HO2S
Water in the harness connector
Open/shorted HO2S circuit
Corrosion or poor mating terminals and wiring
Excessive fuel pressure
Leaking/contaminated fuel injectors
Leaking fuel pressure regulator
Low fuel pressure or running out of fuel
Vapor recovery system
Air leaks after the MAF
Improperly seated engine oil dipstick
Stuck EGR valve
Leaking diaphragm or EVR
Exhaust leaks before or near the HO2S(s)
What would you all recommend I do to try and correct this problem? Is this most likely some kind of O2 sensor or some kind of part that I can easily swap out. What would be the *most* likely cause and or solution for this type of code?
Thank you all in advance.
