you replaced it , but is it working , is getting power to it , the ecm receives tps signal :The TP sensors provide the engine control module (ECM) with a signal voltage proportional to throttle plate movement, is the ecm working

who scanned it and what scanner was used , like local parts stor basic code reader ?

2006 Chevrolet Cobalt

Components

THROTTLE BODY ASSEMBLY

The throttle assembly contains the following components:
- The throttle blade
- The throttle actuator motor
- The throttle position (TP) sensor 1 and 2

The throttle body functions similar to a conventional throttle body with the following exceptions:
- An electric motor opens and closes the throttle valve.
- The throttle blade is spring loaded in both directions and the default position is slightly open.
- There are 2 individual TP sensors within the throttle body assembly.

The TP sensors are used to determine the throttle plate angle. The TP sensors provide the engine control module (ECM) with a signal voltage proportional to throttle plate movement. The TP sensor 1 signal voltage at closed throttle is near the 5-volt reference and decreases as the throttle plate is opened. The TP sensor 2 signal voltage at closed throttle is near the low reference and increases as the throttle plate is opened.

no efficiency on gas , and i keep smell fuel when the engine start
Chevy Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 4 months ago

ok, battery draining , could be ,weak battery, loose ,corroded cables or alternator not charging ?

so we need to check that first if u have not already

if the electrical not working correctly ,and battery drain ,it will throw the car in limp mode or reduced power

if that is good then we have to check on if a module drain the battery and parasitic battery drain test needs done

why was bcm replaced ? and was it used ?

sound u been throwing parts at it ,

the smell of fuel is cause the af ratio is not correct ?

all that happend when the weather was extremely cold
Chevy Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 4 months ago

To be honest with you You will need a Capable Factory scanner or equivalent to Read the Fault codes in the Modules needed here ,that is done by hooking up the scanner to your vehicle DLC data port connector and based on these faults we can pull up a Pin Point Troubleshoot and be Accurate ,If you do get the Faults Read ,Please post them back here for me and I can Help You Further on it and send you the pin point troubleshoot to perform or the most possible causes for it .so we are not throwing parts at it

Please Let Me Know

Thank You
