Question about Ford Expedition

1 Answer

I have a 2003 Ford Expedition with a problem code of DTC P0125 showing when I connected a AutoXray Code Reader to it after seeing a check engine warning light. After clearing the trouble code once, it has returned intermittently when the vehicle is driven. The engine is running a little rough at times also when this occurs. The vehicle is well maintained with regular servicing and has 145k miles. Any suggestions for resolution?

SOURCE: Escort check engine light - code = P0125

Sounds as if the car is not getting warm enough, which could mean that your thermostat is stuck in the open position. Try changing it. That should take care of the problem. Depending on which brand you get, the thermostat will most likely cost you between $8.00-$16.00.

Also, check the coolant level. Make sure its at a proper level. The Temperature Sensor could be bad as well.

Hello;
Looks like the coolant temp sensor for the ecm has started to go out. Test and replace, clear codes and should be ok.

I would take it in and have them do a diagnostic on it, sounds like the cam shaft sensor to me.

P0125 is Insufficient Coolant Temp For Closed Loop Fuel Control

P0756 is Shift Solenoid B Performance or Stuck Off
P0340 is Camshaft Position Sensor Circuit Malfunction

The P0125 can probably be cleared by replacing the thermostat. That part is under $15.00
The P0340 can probably be cleared by replaceing the Cam position sensor. That part is about $25.00

The P0756 is a transmission issue and It will involve removing the fluid pan and taking out the valve body to get to the solenoid.

The thermostat and cam sensor should take about an hour of shop time to change so I would figure about $150.00 to $200.00..Depends on the shop and if there is a minumum charge. Some shops charge 4 hrs. min.

the trans issue may get involved so I don't really want to make a guess, but I would say less than $500.00, depends on what all is involved in getting to the solenoid and changing it.

2003 ford expedition check engine light is on. It is reading a p405 code which is the egr sensor. I have change the sensor and the pig or electrical code twice . I brought the sensor from ford.


This DTC says nothing about changing the sensor or the connector or pig tail ! It's a circuit voltage low code
P0405 - DPF EGR Sensor Circuit Low Voltage Detected See DTC P1400 Problem with wiring or PCM !
P1400 - DPF EGR Sensor Circuit Low Voltage Detected The EGR monitor checks the DPF EGR sensor signal to the PCM for low voltage. The test fails when the average voltage to the PCM drops to a voltage less than the minimum calibrated value.
  • DPFEGR circuit short to GND
  • Damaged DPF EGR sensor
  • VREF short to GND
  • Damaged PCM
A DPF EGR PID reading less than 0.2 volt with the key ON and engine OFF or running, indicates a hard fault.

I have a P0456 code on my 2003 Ford Expedition. Where is the vapor purge solenoid or the canister?


The information you are asking for varies depending on how the vehicle is equipped ie. ENGINE SIZE, AUTOMATIC or MANUAL TRANSMISSION, 2-WHEEL DRIVE, 4-WHEEL DRIVE, ALL-WHEEL DRIVE, etc.
With that said, it also deserves mention that there is a Technical Service Bulletin published by Ford Motor Company that applies to the model year and model that you have listed that involves Diagnostic Test Code (DTC) P0456.

Please note that this bulletin emphasizes the requirement of special equipment to properly diagnose and repair the DTC's listed in the bulletin. Below is a brief (partial) description of the bulletin:

This may be caused by loose or leaking hoses, loose or broken fuel cap, a leak at the top of the fuel filler pipe neck, etc.
ACTION
Use the Rotunda Leak Detector Smoke Machine (Part 218-00001) or equivalent, to locate and repair leaks in the Evaporative Emission System.

DTC P0125 - Insufficient Coolant Temperature For Closed Loop Fuel Control

This means that the engine coolant temperature (ECT) sensor indicates that the engine has not reached the required temperature level to enter closed-loop operation within a specified amount of time after starting the engine.

Symptoms: You will likely not notice any drivability problems.

Causes: A code P0125 may mean that one or more of the following has happened:
* Insufficient warm up time
* Low engine coolant level
* Leaking or stuck open thermostat
* Faulty coolant temperature sensor

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back.

If the code comes back, the problem is likely going to be the result of the above causes (faulty thermostat, faulty ECT sensor, or a low coolant level).

Hope this helps (remember to rate this answer).

Check engine light is on and it runs rough


You will need to pull a DTC (computer diagnostic code) from the PCM (engine computer). This will require a code reader ($40.00) or you can go to an Autozone and they can pull this code for free. Then, and only then, can a diagnostic procedure begin. The computer in vehicles today have the ability to assist us in repair procedures.

Generally this turn on when have any problem with the emission sensors; to know excalty what fault code there, make one scanned the PCM in autozone or autoshop with OBD Codes Reader.

With this code number we could send aditional details.

Hope helps (remember to rate and comment this).
