I Want To Know More About The 5.4!

[Ernest T Bass]

Seeking information on new 3-valve 5.4 engine. Particulary interested in how the PCM interfaces with engine, input/output of the PCM. I would like have a list of all sensors on the engine; O2, MAP, etc... What is the PCM receiving back from the engine and what the PCM is controlling with reference to the engine. Is there a website with a schematic? Any Ford techs out there with some info? I'm considering buying Ford Factory Service Manual for this info, any suggestions?

dont get a service manual for this, get a PCED

[Ernest T Bass]

Excuse my ignorance, but what is a PCED?

[Quintin]

Powertrain Control and Emissions Diagnosis manual. There's the normal workshop manual for most body, chassis, electrical and engine components and systems, and then there's the PCED that deals specifically with drivability and electronic engine controls.

[Ernest T Bass]

Are PCED's for sale to the public? This would be for a 2005 5.4L.

A mechanic at my local Ford dealership gave me a list of "Typical Diagnostic Reference Values". This list consist of the sensors and inputs to and from the computer. These sensors and inputs are abbreviated on the list. Where can I find the terminology for these abbreviations?

[kidtriton]

this is the "real deal"

2005 PCED

[Ernest T Bass]

Thanks for the info. Is there any info on the web that would define the abbreviations of sensors/inputs or PCM Pin/PID?

[kidtriton]

name the ones you dont know and i will tell you what they are.

You got mail, I wanted to post it here for all to see, however the forum limits my post to 5000 characters.

T Bass, be aware that very little of the information will be of any value unless you have a CAN (Controller Area Network) compliant scanner.

kidtriton,

I noticed on the list the mechanic gave me that the sensors/inputs are broke down in 3 catagories; Transmission, Body/Cowl, & Engine. I am assuming that each Pin/PID begins with either "T" for transmission, "B" for body/cowl & "E" for engine. But I noticed something odd in this identification system. For example, there is a Pin called "MAF V" labeled "B41". Doesn't MAF = Mass Air Flow and why is it in the "Body" catagory?

Here are a few Pin/PID & abbreviatrions I have a question about:
E31 KS1 & KS2
E47 CKP
E32 FRP V/FRP
E41 CHT V/CHT- Cylinder Head Temp?
E60 TP1 NS
E61 TP2 PS
E43 IMRCM
E50 IMRC
E17 CDA (CYL1)
E34 TACM
E65 EVMV
E67 VCT1
E69 HTR11

rtremaine,

Is CAN/scanner available to the public for 2005's?

Someone explained that to me before, but I've forgotten. Here's the best I can remember these PIDs though:

Knock Sensors 1 and 2
Crank Position Sensor
Fuel Rail Pressure sensor and FRP sensor voltage.

Cylinder Head Temperature in degrees, and CHT voltage.
Throttle Position 1 and 2, I think. The ETC uses two different "stops" to determine where the throttle is in relation to where your foot is on the accelerator, a fault will set a correlation error code, where the PCM is basically saying it hasn't got a clue about what the hell the TPS is reading.

Intake Manifold Runner Controls, which don't matter, the 5.4 3V ain't got those.
CDA, I'm not sure about, cam angle I think.
TACM, dunno what that is either.
EVMV, electronic vapor management valve, EVAP stuff.
VCT1, bank 1 cam phaser timing variance in degrees.
HTR11, heater circuit for 1-1 O2 sensor.

Info was helpful.
