2003 Chevy Trailblazer engine power lose light come on


Hi Steve , your vehicle has electronic throttle control . I don't know if you are aware of this. The gas pedal have position sensors an a wiring connector with 4-6 wires .these wires are connected to the engine computer . an there is a electric motor on the throttle body assembly , the computer opens an closes the throttle . You probably have codes stored in the engine computer .
Reduced Engine Power Mode When the PCM detects a condition with the TAC system the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.

?€¢
Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.

?€¢
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.

?€¢
Forced idle mode--The control module will perform the following actions:

-
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.

-
Ignore accelerator pedal input.

?€¢
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.

What are the electrical readings on the throttle positioning sensor


The throttle position sensor has both an idle contact switch and a basic 3 wire potentiometer that measures throttle angle opening. The idle switch and the throttle potentiometer share a ground wire.
To test the sensor first you have to verify that the wiring is intact by
1. Disconect the sensor and with a volt meter check the 4 wires. I have attached a wire diagram and picture of the pin layout to make it easy for you.
Pin 1 ( Yellow wire) is the PCM reference voltage. Specification is 5V
Pin 2 ( Red and Green wire) is the signal wire for the TPS. Specification is 5V
Pin 3 (Blue and white wire) is the idle switch. Specification 5V. Please note that this circuit is not actually used by this year Sedona so some vehicles are missing the wire.
Pin 4 (Black and yellow wire) is the ground. Specification: continuity to ground ( less than 1 ohm)
If the voltages are correct next you want to check the sensor.
1. Connect the throttle sensor connector.
2. Key on engine off
3.With a voltmeter measure terminal 2 of the sensor with the throttle closed, Specification is .2 to.4 volts.
4. With ta voltmeter monitor terminal 2 with the throttle fully open.The specification on terminal 2 is 4 to 4.4 V.
5. Slowly open and close the throttle while monitoring terminal 2 and make sure you have a smoot increase and decrease in voltage as the throttle is moved from close to open throttle and returned to idle.

I have a 2005 GMC 2500HD code P1516, already replaced APP. Still dies, reduce engine speed comes up. What is the next step?


The Throttle Actuator Control (TAC) / throttle body type trouble codes, may be caused by a loose wiring crimp at the throttle body connector, or a broken throttle body circuit.Inspect all related throttle body terminals for a loose wiring crimp. The loose crimp may be difficult to find, and the poor connection will be between the terminal and the copper strands of the wire. Wiggle test the individual throttle body circuits to see if the concern can be duplicated.
Inspect the related circuits for broken wires inside the insulation. The outer wire insulation may look fine, but the internal copper strands may be partially broken. Breaks in the wires usually occur within 1 to 4 inches of the throttle body connector. Wiggle testing may also induce a trouble code to set.
On C/K trucks complete SI procedures for voltage drop on grounds G103 and G104. Grounds G103 or G104 may be loose or corroded. If a terminal crimp or a broken wire has been found, repair or replace only the circuits involved. There is a throttle body pigtail connector available through GMSPO, post back with what you find.

i have the same problem did you find a solution? anyone know what this is used for min has cut wire under carb and on the auto throttle it will only run with carb wide open i tired the two wires under carb and that just shuts fuel off or on with a needle with 12v applied.

Ryoby weedeater throttle housing. Replacing the throttle spring


From the limited information you have given I think your throttle wire is binding. It could just need lubricating or the throttle shaft or butterfly in the carburetor could be binding. Disconnect the throttle wire from the carburetor and see if the throttle wire is moving freely and check the throttle shaft in the carburetor to make sure it is moving freely. If both are free, then check to see if something is pinching or binding on the throttle cable.
