hey so i have a 2011 camaro ls and i got a bunch of random check engine light codes (note my car only has 50,000 miles) and so i took it in they replaced the battery and that got rid of all but three of the codes then after deiving for 30 minutes the check engine light shut off but i i plugged in the obd and there was still saved codes for p0122 and p0223 and one for throttle position sensor idle not yet relearned and since my light was off i didnt think too much into the saved codes but im noticing a really unresponsive throttle and way worse acceleration my question is what should i get fixed i know its all throttle position sensor codes but do i have to get the entire throttle body fixed?

 

P0122 =The ECM detects the TP sensor 1 signal voltage is less than 0.18 volt for greater than 1 second.
P0123=The ECM detects the TP sensor 1 signal voltage is greater than 4.6 volts for greater than 1 second.
The TP sensors are mounted to the throttle body assembly and are not serviceable.

 

thanks i figured that out! so i ordered an entirely new throttle body assembly, once i install it do i have to do a relearn or program it? or just take the old one out put the new one in

 

6 cylinder:

1. Turn OFF the ignition for 30 seconds.
2. Turn ON the ignition, with the engine OFF for 60 seconds.
3. Turn OFF the ignition.
4. Turn ON the ignition, with the engine OFF.
5. Clear the DTCs with a scan tool.

8 cylinder:

1. Start and idle the engine in PARK for 3 min.
2. With a scan tool, monitor desired and actual RPM.
3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease.
4. Ignition OFF for 60 s.
5. Start and idle the engine in PARK for 3 min.
6. After the 3 min run time the engine should be idling normal.
   Note: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.
   • If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles.
7. After the drive cycle, the engine should be idling normally.
   • If the engine idle speed has not been learned, turn OFF the ignition for 60 s and repeat step 6.
8. Once the engine speed has returned to normal, clear DTCs

 

thankyou! imgoing to try it in a couple hours when my part comes in ill let you know how it goes
