SOURCE: electronic throttle control light comes on,car

I am not to sure but I know that there is a process called the "Relearn" which mainly zinchronizes the throttle body with your ECU... But I am not to sure for a ford exactly I know that for a Nissan if you getting code P0507 the relearn Process will follow as: 1. Warm up the car to normal temperature of drive it for a few minutes and turn it off. 2. After you shut off the engine wait ten seconds. 3. Turn the Key to the ON Position but don't start the car. 4. Wait 3 seconds and press the gass pedal and release 5 times in whitin 5 Seconds. 5. Give it a 7 seconds and press the gas pedal and keep it pressed for about 10-15 seconds and the engine light should star blinking for about 15-20 seconds as soon as it stops blinking start the engine let it run for about 20 seconds and rev the engine up a couple of times then you can shut it off.
But I had a couple of time in which a rebuild piece might fail to sync with the relearn process...You might need to go with a new part....Good Luck. I am kind of sure that Ford migh have a forum those sites are very helpful because of they are Ford Vehicles owners that will post their solutions to similar issues.


Good Luck! CR.

SOURCE: electronic throttle control light flashing

Depends on the vehicle & make

Could be the gas pedal (APP) if you go to a wiring diagram

General Description could be the throttle body

There is no guessing here

You need to check for codes & have trouble charts
to follow to resolve any problems

You can not fix yourself,a dealer or repair shop will be needed

Code p0506 on a 03 grandmarquis battery light comes on and stalls.


Does yours have electronic throttle control ?
P0506 - Idle Air Control System RPM Lower Than Expected (Electronic Throttle Control [ETC] Vehicles) The PCM attempts to control engine speed during KOER self-test. The test fails when the desired rpm could not be reached or controlled during the self-test.
  • Air intake restriction
  • Exhaust restriction
  • Engine mechanical fault
  • Damaged electronic throttle body (ETB)
  • Damaged PCM
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 or vacuum leaks and damage. If no concerns are present, clear the DTC and retest. P0506 - Idle Air Control System RPM Lower Than Expected (All Others) The PCM attempts to control engine speed during KOER self-test. The test fails when the desired rpm could not be reached or controlled during the self-test.
  • IAC circuit shorted to PWR
  • VPWR to IAC solenoid open
  • IAC circuit open
  • Damaged IAC valve
  • Damaged PCM
  • Air inlet is plugged
The IAC solenoid resistance is from 6 to 13 ohms. Monitor IAC PID duty cycle and/or voltage.

Correct code P0504?


What Colorado do you have ? 2 wheel or 4 wheel drive ? Sport ,sport LS 3.5L , Z71, Z71 LS. etc. what size engine ? an does it have electronic throttle control ? I have factory service info an it is not showing that code .
DTC P0506

Circuit Description

The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

DTC Descriptor

This diagnostic procedure supports the following DTC:
DTC P0506 Idle Speed Low

WHAT MEANS WHEN "ETC POWER"IS ON?


seems something wrong with the Electronic throttle control (ETC) which is an automobile technology that electronically "connects" the accelerator pedal to the throttle, replacing a mechanical linkage
There is no mechanical linkage between the accelerator pedal and the throttle valve with electronic throttle control. Instead, the position of the throttle valve (i.e., the amount of air in the engine) is fully controlled by the ETC software via the electric motor.
- you better have the ETC immediately serviced by an approved Toyota-shop

Major vacuum leak


A vacuum leak is unlikely to hold RPM that high. 1st inspect throttle plate not closed all the way, possibly hung up, or cable pulled too tight holding throttle open or accelerator pedal not releasing completely. If ok, next would be a computer controlled issue , Possibly idle speed control motor or throttle body assembly if not cable operated .

My monte carlo has code p0507 what is it and how can i fix it


possible causes
- Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve
solution !!!
If there are no intake leaks, clean throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replaced the Electric Throttle Control Actuator (Motor) to repair the problem.

2005 F150 5.4 Cuts off when driving at constant speed and show "Engine Fail Safe Mode" on display. It will crank back up and run for several hundred miles before doing it again. P2112 Throttle Air...


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

Loses the power and starts stalling


The IAC valve requires resetting .
First locate the IAC valve located on the side of the throttle body and has 4 wires going to it .Procedure is as follows
Ignition key on ,unplug the IAC ,turn key off ,reconnect the IAC .do this 3-4 times .restart the car and hold the rpm at 2000 rpm and slowly lower until it idles by it self .
