I'd bring it back to the shop that put in the throttle body and have them check to see if the replacement was defective or failed. If not, you may have a bad throttle position sensor [part of the gas pedal] I'm assuming it worked fine for a while after the repairs with no problems then suddenly started acting up again. I've replaced a bunch of throttle bodies but only one position sensor so far. There's always the chance that there's a bad wire somplace or some other more exotic problem but I'll bet you'll find it at either the sensor or throttle body. Good luck, hope this helps!

I just got my alternator fixed then i started having the ESC serv ice light come on, and the trac symbol comes up and the engine light flashes. and the power is reduced and it jerks when driving


its possible that the incorrect voltage regulator was fitted to the alternator during the repair. A low voltage or irregular voltage from the alternator can cause havoc with vehicle electronics

Not sensor , SENSORS ! This message reduced engine has to do with the electronic throttle control !

Reduced engine power


Have the vehicle checked for DTC'S - diagnostic trouble codes ! Do you know what electronic throttle control is ? The gas pedal assembly has electrical connector an sensors inside ,hooked to the PCM / ECM - engine computer . The engine computer uses these position sensors inputs to control the DC motor on the throttle body to open the throttle plate to control the speed . Plus there are position sensors inside the throttle body to input PCM/ECM to see if it's calculations are corect . Your best bet maybe to take it to a qualified repair shop .

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.

2005 VW Beetle. Engne light on and EPC light comes on with significantly reduced power.


Sounds like all those sensors are going to need replaced. Basically, they are all in charge of metering the air and fuel to the engine, so if they are malfunctioning, the car isn't going to run correctly.

Yes the throttle and pedal sensor can do this, but doesnt reduce power,Your cam postion sensor reduces power and if you thing it gives a engine code,it doesnt have to,This sensor is back up by the crank position sensor,The location of this sensor is in the back of the cylinder head

I have a 2005 dodge durango limited 5.7 liter engine. My engine light an my etc light came on. The power reduced and I pulled over. Now my engine light remains on but the etc light has not appeared again.


Well, the ETC light often comes on as a result of a sticky throttle plate, but doesn't trip the Check Engine. First, I'd clean the throttle body plate off. You do this by removing the big air box on top of the engine and just cleaning all round the inside of the throttle body with a rag and some carb cleaner.

Next, you should go to an auto parts store that will let you use an ODBII scanner to read the engine code and post the codes here. However, if your throttle body is really dirty, you can try and just reset the computer yourself and see if the light comes back. To reset the computer, unhook the positive and negative battery cables. Hold the two disconnected ends together, metal to metal, for 60 seconds. Some times this takes longer, but 60 seconds usually does it. This should reset the check engine light.

Oh, and depending on what tripped the check engine light, Chrysler has a funny way of just leaving the light on for a set period of time. If the problem is resolved the light will stay on until you drive a certain distance, above a certain speed. Unfortunately, this varies and I just don't know what your SUV needs.

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
