SOURCE: 2002 Ford Windstar Error Code P1131 And P1151

those two codes are for the o2 sensors. both are the upstream sensors on the front and rear banks. so they are desinagted bank 1 sensor 1 and bank 2 sensor 1. them most common cause for this is faulty o2sensors , bad gas and of a poor running engine. so if your car runs good (no misfire) and gas is ok then replace the o2sensor witch is the very most common cause.

SOURCE: how to fix ford contour code p0708

this code indicates a problem with the transmission range selected switch, this switch is on the transmission case where the shift cable attaches, when u select a gear it sends a signal to the computer control that u want lets say Reverse by sensing the range selector switch feedback, replace the switch will most likely cure the code, then clear the code and drive a few miles.

Does Changing a P1151 and P0175 on a ford Wind star solve the problems associated with it?


P1151 is indicating an problem with the upstream O2 Sensor on Bank 2. Bank 2 is the even cylinders side O2 sensor. The P0175 code indicates a rich condition in Bank 2 exhaust. This indication, if by itself, would indicate a faulty MAF Sensor or a vacuum leak, but since you already have the P1151, change the Bank 2 O2 sensor first and most likely both codes will clear.

PO171 and P1131 point to lean codes on bank PO174 and P1151 point to lean code on bank PO305 is missfire on cyl 5

the lean codes is probably a vacuum leak or maybe a MAF sensor is bad or dirty

missfire is dependant on engine if a V10 it may be a coil actually pretty likely on the modulars not uncommon thats for sure
sorry forgot to add that its says missfire on #5 cant remember if that one is the first on the left or last on the left facing the engine vacummn leak could be those dang auto hubs got it stuck in the mud and they did not engage I need to buy some new ones took them apart to clean them out this summer

I have a 1998 ford contour that has codes p1130 and p1131 on it what could be the problem. the check engine light is on


H40 DTCs P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTC P1130: FUEL SYSTEM NOT SWITCHING AT FUEL TRIM (RICH OR LEAN)
    Diagnostic Trouble Codes (DTCs) P1131 bank 1 (Cylinder 1) and P1151 bank 2 indicate the fuel/air ratio is correcting rich for an overly lean condition. The HO2S voltage is less than 0.45 volt. DTCs P1132 bank 1 (Cylinder 1) and P1152 bank 2 indicate the fuel/air ratio is correcting lean for an overly rich condition. The HO2S voltage is greater than 0.45 volt.
    DTC P1130 and P1150 indicate the fuel control system has reached maximum compensation for a lean or rich condition and the HO2S is not switching.
    DTC/HO2S Reference List
    • HO2S-11 = DTCs P1131, P1132 and P1130
    • HO2S-21 = DTCs P1151, P1152 and P1150
    Possible causes:
    Fuel system
    • Excessive fuel pressure.
    • Leaking fuel injector(s).
    • Leaking fuel pressure regulator.
    • Low fuel pressure or running out of fuel.
    • Contaminated fuel injector(s)
    • Vapor recovery system
    Induction system
    • Air leaks after the MAF.
    • Vacuum leaks (vacuum lines and gaskets).
    • Restricted air inlet.
    • PCV system.
    • Improperly seated engine oil dipstick.
    EGR System
    • Leaking gasket.
    • Stuck open EGR valve.
    • Leaking diaphragm.
    Base engine
    • Oil overfill.
    • Cam timing.
    • Cylinder compression.
    • Exhaust leaks before or near the HO2Ss.
  • Check intake air system for leaks, obstructions and damage.
  • Check air cleaner element, air cleaner housing for blockage.
  • Verify integrity of the PCV system.
  • Check for vacuum leaks.

I have a Ford F250 Extended cab that started running rough and losing power this morning got Codes P0301 P0303 P1151 and P0171 What should i Do?


P0301 = Misfire cylinder #1P0303 = Misfire cylinder #2
P0171 = System too lean cylinder #1
Are you sure on the P1151 code? I am thinking this may be a P0151 which is O2 sensor related.
This looks like you have a fuel system related misfire. I would do a fuel injection cleaning service and then clear codes and see if the codes regenerate.
