Check for vacuum leaks, broken vacuum hoses, etc to start.

SOURCE: im having issues with my 03 linconl ls the check

I would start with the coils. Almost all problems seem to be from that area. Maybe buy one at car salvage and shot gun it out. I think it's worth a try. Need to start eliminating possible causes. Yes alot of codes - need to find a commom dinomatator. Good luck

SOURCE: my 2005 altima idles high and engine code

This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.

I don't know why you would replace all the coils,I do know,
but I don't do diagnostics that way.

The TACM (throttle actuator control motor) is part of the
throttle body, and can not be replaced

The PO2104,PO2107,PO2110,PO2111, are TACM related codes
I won't write a book on it,you got what they are, from your
friends scan tool

If all the coils are good,then they are not spiking the PCM,
coming back on the TPS Sensor and putting it into ETC Failsafe
(that senerio the dealers are not up on )

I would buy some CRC Throttle Body Cleaner, and spray the
throttle plate, won't fix your issues, but does on a ford explorer

Hopefully you can slowly move the throttle plate and free it up
The throttle body is about $470,up from $325 a year ago,from
a dealer.
It only has 4 ,10mm bolts,so you can solve this at home

Forget the Cam Code for now

I would back probe the TPS Sensor, with a couple needles,
and use your volt meter to check
It has two sides--0v to 5v & 5v to 0v

one 5v ref from pcm,one ground, you can stay on,and red lead
to either of the other wires to test TSP voltage drop,eg .5v to 4.9v
when moving throttle plate

I will check back with you or give you my #

SOURCE: My 2005 F150 with 5.4 goes to Idle while driving.

For this problem, I looked at the Code results. There are a few parts which can cause it, and in some cases the Dealer will need to install a Data Logger if microwave signals are suspected.

Ford has made modifications to this Throttle body, and parts were backordered for a redesigned throttle body. This may be covered under a Silent warranty and a one on one request for factory assistance.

Or you may try to replace the cheapest part, the throttle position sensor, Several people on the F150 forum changed out that part and it worked. Myself, even changing the sensor, I would want the best throttle body made for my truck. So rather than a patch, if a free factory replacement were offered, I'd take that.

Contact your favorite Dealer and see what they will do for you.

Emissions light is on 2005 Ford Expedtion


Thanks for the inquiry,
I did some research and found that this error usually generates codes that both source back to the electronic throttle control on your engine. Go down to one of the major auto parts stores and they will check the codes for you usually at not charge.

Most common: [P2104-Throttle actuator control system-Forced Idle] [P2112-Throttle actuator control system-Stuck Closed]
Having not examined the vehicle, I'd suggest two things for you:
First- replace the controller, which is attaced to the throttle body with one from a salvage yard.
secondly- get some old rags and clean inside the throttle body using carb cleaner.

With luck, this should clear up your problem.

Best regards,
TF

unfortunately no ! Your best bet take it to the dealer . The P0420 always ends up being the catalytic converter ! P2104 isn't throttle air control . P2112 - Throttle Actuator Control (TAC) System - Stuck Closed. Description: This powertrain control module (PCM) fault status indicates the throttle plate is at a lower angle than commanded. Possible Causes:
  • Binding throttle body, stuck closed.
  • Damaged PCM.
Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV1
P2104 - Throttle Actuator Control (TAC) System - Forced Idle Description: The TAC system is in the failure mode effects management (FMEM) mode of forced idle. Possible Causes:
  • Open or short in multiple accelerator pedal position (APP) sensor circuits.
  • Damaged APP sensor.
  • Damaged powertrain control module (PCM).
Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to QE1
P0506 - Idle Air Control (IAC) System RPM Lower Than Expected For Vehicles With Electronic Throttle Control (ETC) Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:
  • Air intake restriction.
  • Exhaust restriction.
  • Engine mechanical fault.
  • Damaged electronic throttle body (ETB).
  • Damaged PCM.
Diagnostic Aids: This DTC is informational only and it may be accompanied by other DTCs. Diagnose other DTCs first. If other DTCs are not present inspect the intake air system for air restrictions and damage. If no concerns are present, clear the DTC and retest. For All Others Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:
  • IAC circuit open.
  • Air inlet is plugged.
  • B+ or VPWR to IAC solenoid open.
  • Damaged or incorrect IAC valve.
  • IAC valve stuck closed.
  • VPWR to IAC solenoid open.
  • IAC circuit shorted to PWR.
Diagnostic Aids: Disconnect the IAC valve and look for little or no change in engine RPM as an indication of a stuck or damaged valve. Application Key On Engine Off Key On Engine Running Continuous Memory Vehicles With Electronic Throttle Control (ETC) Refer to the Description, Possible Causes and Diagnostic Aids for the DTC. All others GO to KE1

My check engine light has come on for my 2006 Ford Fusion and 3 codes came up...P0010, P2104, and P2112. Any ideas what these mean?


Fuel and Air Metering and Auxiliary Emission Controls P2104 Throttle Actuator Control System - Forced Idle
P2112 Throttle Actuator Control System - Stuck Closed
If it's not the pedal, it has to be throttle body, senor or harness related.
