What is the most likley problem if I have a erratic idle only when the engine and oil temp are warm? As soon as you touch the throttle it clears right up. I still have the original software or flash from 03. Never have had any problems since I bought new. The chenk engine light also has just come on. I know it has to be a sensor but what one. If I go to the auto parts store and rent a programer will they haveon that can read the codes on a 6.0?

Thanks for your help.

 

They usually have one, what reads DTC on the PSD.
Erratic idle..... my first clue would be ICP sensor, what is located under the turbo on the 03. If I'm right ( code is related ), don't wait to replace it, because ICP failure could leave you on the side of the road.

Thanks I will give the ICP a shot. Thought that may be it or the EBP. I will try the DTC first though.. Where is the best place to buy the ICP? Online or parts store. Does anyone have the part #?

 

The EBP was removed from the parameters with this recall.2003/04 Computer Programming Recall 06E17:
Truck built before 9-29-03 are being recalled to have the computer reprogrammed. The reason for this recall is to correct fuel injection timing during cold operation, EGR valve control, lack of power, check engine light illumination (P02263 or P0299), hard starting and rough running concerns related to Exhaust BackPressure sensor corrosion. Other symptoms not listed in this recall, but which could occur, would be excessive smoke, turbo control and surging at idle or cruise. The new update eliminates the EBP sensor input to the computer. The exhaust backpressure will now be inferred/calculated using other sensor signals. Trucks should be reprogrammed using versions 41.8 or 42.1 or higher.
After this reprogramming, the truck should be test driven, the computer checked for a codes and the codes cleared (even if none are present), the key cycled on for five seconds, then turned off twice, then the engine started and allowed to idle for 5 minutes at operating temperature to allow the computer to relearn the EGR valve closed position value. This is to prevent erronious codes or driveability sysmptoms related to the EGR valve an turbo performance. Broadcast Messages 5452, 5529.
You should notice an increase in turbo cycling closed/whistling at idle and at stops. This is normal, and is to help keep the variable vanes from sticking.
If your truck wasn't effected by the recall EBP Part number is in this one.2003-05 Various Running Problems, Check Engine Light; New EBP Sensor:
Trucks built before 1-17-05 that exhibit buck/jerk, hesitation, lack of power, stalling, stumble, black smoke, surging, rolling idle, changes in engine sound at idle or when driving at a steady speed, or with the trouble codes P2263 or P0299, may have an exhaust backpressure sensor signal that is incorrect or erratic. A revised EBP sensor is available if this is found to be the case. Part number 4C3Z-9J460-A. Broadcast Message 3815.
Normal EBP signal reading should reflect atmospheric pressure with the key on/ engine off. Typically, this is 14.7 PSI/0.88-0.9 volts at sea level, decreasing one PSI/0.10 volt for every 2000 feet of elevation. It should be within 0.5 PSI of BARO and MAP sensor pressure signals.
The ICP is in this one.ICP Sensor Problems:
This is now covered by Customer Satisfaction Program 03B05. It applies to trucks build through 2-3-03. The program will be in affect until 12-31-05. Ford is authorizing a free oil and filter change under this program until 12-31-03.
Some 6.0 PowerStroke engines may exhibit rough/rolling idle, poor idle return, lack of power, injector fault codes or excessive smoke. This may be caused by the ICP sensor reading incorrectly. The ICP sensor and connector terminals should be inspected for damage (the ICP is at the rear of the engine, under the turbo), and the sensor circuits checked for opens or shorts. With the engine at operating temperature (engne oil above 180 degrees), the ICP sensor signal should be 0.16-0.28 volts (less than 70 PSI) with the key on and engine off. The engine needs to be off for at least two minutes for this test. If the ICP signal is not within this range, replace the sensor with P/N 3C3Z-9F838-EA.
Last but not least.ICP/EBP Sensor Repair Kit:
Both PowerStroke engines may exhibit codes related to the ICP(7.3: P1280; 6.0: P2285) and/or EBP sensors (P0472). If these codes are present, clear them. Start the engine and wiggle the sensor connector that matches the stored code. If the code returns, replace the sensr connector--P/N 3C3Z-12224-BA for 94-96; 3C3Z-12224-AA for 97-2004.
