Problems with sensor code po506 on 1996 ford explorer. Need soultion

Code Readers give a code, what was the code?? Codes warn of impending disaster or a total failure being imminent. Sensors are an important part of the engine running correctly and burning fuel efficiently. For instance, too much fuel added, equals a high fuel bill and sooty plugs which will fail. Conversely, too lean a mixture causes the engine to make too much heat in the combustion chamber, burning spark plug tips, burning valve rims and melting piston crowns.

It appears to be a Fuel Rail Pressure Sensor. Were you low on gas going up the hill?

TAKE IT TO A FORD DEALERSHIP AND HAVE THEM RUN A DIAG ON IT. IT WILL SAVE YOU ALOT OF HEADACHES IN THE LONG RUN. OTHERWISE YOU MIGHT BE SPENDING ALOT OF MONEY ON GUESSING THE SOULTION.

Why would you change any sensor more than once?

You clearly have no idea why you get an OBD2 Mil Lamp
on your dash

Codes have nothing to do with changing parts

You use the codes & diagnostic charts & professional
test equip, to find a problem & component test parts

Unless the actual problem is found & a part tests bad,
it does not get replaced

I only chose the question because no professional repair
shop would throw parts at it repeatedly.

You need a different repair shop or you need to buy the
factory ford diagnostic & emission manuals & wiring diagram
book, if you plan on work on it at home

The internet would be a good place to study that code
on your vehicle make & model

Before i can give you an O2 sensor code I need to find out what kid of vehicle you have and as for the sensor problem you can look to see if one of the O2 sensors are unplug.

Good Luck!

RE: code p2106 /p2175 question The sensor on the pedal is called the (APPS) accelorator positon sensor which sends to the throttle body. The throttle body is the problem in this case.

There is a problem with these electronic speedometers, but 1st have the fault codes read and see if the speed sensor has set a code, if it does have a code for the speed senor replace it, if there is no code for the sensor the speedometer is defective and needs to be removed and send out to a Ford electronics repair center.

Check and clean the MAF (mass air flow sensor). you will need a #20 anti-tamper torx bit and some carburetor cleaner. Be careful with the sensor it is delicate.

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 data
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!
