The malfunctioning part in my case is what ford calls the "integrated wheel end" which locs the weel hub on the four wheel drive in or out as need. Part is available from Ford and cost about $110.00. I will do this repair myself.

Your front hubs are automatic locking hubs, and the gears are hard nylon. These hubs break very easily, therefore causing you to lose your front wheel drive in 4 high, or 4 low. If you replace the hubs with "WARN (name brand) " manual locking hubs, you will never have the issue again. Of course, you will have to get out of the truck and manually lock the hubs, but they are metal gears, and much more durable. I've personally seen the issue several times, and changing the hubs has resolved the issue every time.

Could be a problem with the vac lines to the IWE ( Integrated Wheel Ends ), or a problem with the IWE solenoid, or a problem with the vent from the IWE.

Start with checking the vac lines, to make sure they are not cracked.
The vac res & IWE solenoid are behind the battery. Here is a diagram of the parts in the IWE vac system

There was a TSB for the 2004-2006 MYs with a bad design IWE solenoid, but this usually was coupled with noise in 2WD.
Start with checking the VAC lines and the vent, next would be to check the IWE solenoid.

Here is the PDF of the TSB on IWE solenoid

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vac is removed the spring engages the IWE.

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

- If the front drive shaft does not turn :
Shut of the truck ( still jacked up, and supported ) remove the vac lines from the IWE. The spring should push the gears in, without the vac line on.
Check the vent line ( tube that is routed into the engine compartment with nothing attached to it ), for blockages.
If the vent line is clear, and with the vac lines off the IWE should be engaged ( both front wheels locked ).
If they lock, the problem is with the IWE solenoid not shutting off vacuum to the IWEs. There is a TSB on the 2004-2006 IWE solenoids, a newer revision has been made, and used from 2007 and newer MYs.

Here is a block diagram of the IWE system

If this is a 2004 Heritage ( old body style ) and the transfer case is known to lock in ( check with truck jacked up, shift into 4WD and try to turn front drive shaft ), the next item to look at is the vacuum disconnect motor for the front axle. This is on the front axle, and will move when shifted into 4WD

It is item #10, on this parts diagram

If you do not have movement in this, check the vacuum lines with a vacuum pressure gauge, to see if vacuum is being applied ( Pink line is 2WD w/ vacuum is operation, Blue line is 4WD w/ vacuum operation ). If no vacuum at the lines, check them back to the vacuum shift solenoids

Does you f 150 have electronic throttle control ? An does it have Variable Cam Timing (VCT) - if it does have Variable Cam Timing (VCT) it doesn't have an EGR valve ! What type scan tool did you use to pull the code with ? My FORD factory service information does not show that code for A 2004 F - 150 5.4 L 3 valve engine !

P0372 code


Possible causes


- Timing Reference Optical Sensor harness is open or shorted

- Timing Reference Optical Sensor circuit poor electrical connection

- Faulty Timing Reference Optical Sensor

- Damaged Powertrain Control Module (PCM)


What does this mean?



When is the code detected?


Some high resolution pulses are missing from the optical sensor to the PCM


Possible symptoms


- Engine Light ON (or Service Engine Soon Warning Light)


P0372 Description



The optical sensor provides a high resolution signal to the Powertrain Control Module (PCM) by counting pulses on the sensor disk located in the injection pump. The high resolution is one of the most important inputs by the PCM for fuel control and timing. This test monitors the number of high resolution pulses which have been missed (not detected). It's based on a comparison between the number of pulses that were detected since the last pump cam pulse and the number of the pulses that should have occurred. There are approximately 64 high resolution pulses for every cam pulse.

Error code p0238 and p0113 the car didint start redone timing and the car was fine on the test drive the second test drive it road for approx three kays and lost power and thick black smoke and the...


DTC P0238 - TC Boost Sensor Circuit High Voltage
DTC P0113 - Intake Air Temperature Circuit High InputThe powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

A code P0113 may mean that one or more of the following has happened:Internally failed IAT sensorFaulty connection at IAT sensorOpen in IAT ground circuit or signal circuitShort to voltage in IAT signal circuit or reference circuitIAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)Faulty PCM (less likely but not impossible)Possible SolutionsFirst, if you have access to a scan tool, is there an IAT reading? If the IAT reading is logical then the problem is likely intermittent. If the reading is less than -30 degrees, unplug the connector. Install a jumper wire between the harness connector signal and ground circuits. The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground.
If now the IAT reading on the scan tool is maxed out then check for an open in the IAT ground circuit. If you get no reading at all on the scan tool, it's likely that the sensor signal is open or the 5 volt reference is missing. Check using a DVOM (digital volt ohm meter) for a 5 volt reference. If it's there, then unplug the connector at the PCM and check for continuity on the IAT signal circuit between the PCM connector and the IAT connector.

Hope helps.

Honda accord incorrect gear ratio code p0370


Honda P0370 - Timing Reference High Resolution Signal A Malfunction.

Possible Causes:
- Open or short in the optical sensor circuit
- Optical sensor connector
- Damaged optical sensor
- Damaged PCM
- Damaged ECM

Possible Solutions:
- If damaged repair the optical sensor circuit
- Replace optical sensor
- Replace PCM
- Replace ECM

Not sure where you got incorrect gear ratio. This P0370 DTC is for what I have listed above.
