But the control is a switch. The contacts on the switch connector
may need to be cleaned. The spade portion should be scraped to bright metal the other side may be cleanable with sharp round toothpick.

I have a 2004 gmc sierra 4.8 truck for 3 years it idles down too low and dies at red lights stop signs or when you let foot off gas but put in neutral and it cranks back with no problem, Why?


First off is the check engine light lit ? Do know if Your vehicle has Throttle Actuator Control (TAC) drive by wire -electronic throttle control . It's all electronically controlled . They do get problems like your having because the throttle plate needs to be cleaned !

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

Where is the location of the idle air control valve in a 2004 chevy malibu?


If there are no cables coming off throttle body to control throttle there is no Idle Air Control valve. the idle is controlled electronically by the computer. If car is idling rough you can clean throttle body to correct this problem. If you do have cables to control throttle the IAC valve is located right next to throttle body attached to it. Hope this helps

Electronic throttle control motor


clean the throttle body out with carb or throttle body cleaner. My 2004 Volvo S60 was stalling at stops and cleaning it fixed the problem, the carbon build up doesnt allow it to function properly

Hallo My vw polo clasic 1.8i is running but if you give more petrol it seems like its choking.


Clean your throttle body with a carburettor cleaner but it is better to remove it for better job and whilst cleaning it bear in mind that the throttle is electronic controlled and forcing it you might damage the electronic control system of the throttle spray in the throttle body the carb cleaner till the black dirt goes away. fit it back carefully and also you need a scanner to do the adaptation as ALWAYS ON VWS ANYTHING GOT UNPLUGGED HAS TO BE RESET for better run. If you can not do it ask a qualified mechanic to do the job for you.

How often can a electronic throttle control malfunction


Well, how often would you like it to malfunction? If you say NEVER, it will explode today! (or at least, that would be MY luck...LOL!)

What your ECT needs is to be PROPERLY DIAGNOSED. There are several things that can cause the hesitation and the light to come on, including faults located in the accelerator pedal position sensors, the throttle position sensors, the Powertrain Control Module, or any of the wiring between them.

There is no "cleaning" to be done. Attempts to "clean" an electronic throttle control unit can totally destroy the unit. This is NOT like the old throttle bodies that could be cleaned out by holding the throttle plate open and dousing it with carb cleaner. To begin with, forcing the throttle plate open by hand can break the gears in the throttle control. Then if you do manage to get it open, the carb cleaner can destroy the electronics.

With all that said, there are a couple of Technical Service Bulletins on your Jeep that involve the ECT light coming on and poor drivability symptoms. At least one of them involves reprogramming of the engine control computer.

It should also be noted here that many of the major components of your engine control system are covered under the federally-mandated 8-Year/ 80,000 mile emissions warranty. Reprogramming of the computer is definitely covered under this provision.

My 2006 Hyundai sonata reading on a code reader P2118, P2119, P2110


P2118 - Electronic Throttle Control(ETC) system is made of the components throttle body, Throttle Position Sensor(TPS)1&2 and Accelerator Position Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle properly in response to the driving condition.

P2119 - associated

P2110 - A bulletin provides the procedure to clean the Electronic Throttle Control (ETC)
throttle body of Theta-2.0L/2.4L engine equipped vehicles. If a vehicle exhibits the
condition(s) listed below and deposits are found at the valve-to-bore interface inside the
ETC throttle body, clean the throttle body using the procedure described in this bulletin.

This throttle body cleaning procedure should be performed when diagnosing
the conditions listed below. Do not replace the throttle body prior to performing
this procedure.

Any of the following conditions may be caused by throttle body deposits:
• No start (due to throttle valve stuck closed or air flow signifcantly restricted)
• Rough idle or fluctuating engine speed at idle (due to air flow restriction)
• MIL "On" with DTC P2118 or P2119 occurring along with P2110:
• P2118: Throttle Actuator Control Motor Current Range/Performance
• P2119: Throttle Actuator Control Throttle Body Range/Performance
• P2110: Throttle Actuator Control System-Forced Limited Power

It seems CLEAR you have a STICKING butterfly plate in the throttle body.
