SOURCE: Code #P0171 & code #P0174

The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

Looked up your OBD II code for your Explorer and got the following: Bank 1 Sensor 1
The possible causes are listed below per Chilton: *same result for all engines available on your vehicle

Trouble Code: P0141 (4.0L V6 VIN E Auto)
HO2S-11 Heater Circuit (Bank 1, Sensor 1) Print this code dataprint_icon_codes.gif
Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. The test fails when the current draw exceeds a calibrated limit or an open or short circuit is detected.
Possible Causes:

  • Vacuum hose disconnected on exhaust gas recirculation (EGR) system module (ESM) applications* Short to VPWR in the harness or HO2S
  • Water in the harness connector
  • Open VPWR circuit
  • Open GND circuit
  • Low battery voltage
  • Corrosion or incorrec
The sensors themselves appear in the illustration linked to below. The illustration is for the Ford Ranger but indications are that other models have similar locations. Hope this helps with your problem. Best of luck!

Code po172, po156


Have you had the O2 sensors checked ? Code 172 is for a rich signal from bank one sensor one and code 156 is for a problem with bank two sensor two which is after the catalytic converter.
One of the injectors could be flooding a cylinder, or you could have a faulty sensor.

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

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

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.
