2008 cadillac cts 3.6 codes showing are p2176 and p0420 what does this mean

P2176 is the Throttle Actuator Control System
See the hyperlink below for info on this code:

P0420 is Catalyst System Below Efficiency (i.e. catalytic converter on the exhaust system.)
To check your catalytic converter, get a very light, small finishing nail hammer and tap the catalytic converter lightly, if you hear rattling inside it then it's shot. If your exhaust pipes are rusted through anywhere, get it all done at the same time. You can DIY using parts from Walker Muffler... schematics are available on line, get new hangers too!

My H3 Hummer 2006 is giving me p1516 p2176 p2135 p2176 and p2135 codes what to do so I fix it

code p 2176 refers to both the accelerator position sensor E and the throttle position sensor E--maximum stop performance ===causes --wiring---APP or TP sensor
code p 2135 refers to same items but switchF A/B- voltage correlation or implausable signal===causes --same as previous
I have no listing for a p 1516 as the book does not cover it but I am guessing that it is a specific code to hummer and still related to the problem area of the APP or TP units
if you find and fix the APP or TP problems then that code by go

Please help the car works fine, but after half an hour Athaddamha gearbox shifts vary in pedal and petrol go up and after Alchiek found these errors in the display panel: P2176 - Minimum Throttle Position...

the translation isnt very good but i think from the codes you need a new throttle position pedal sensor ,its the one on teh throttle pedal under the dash ,the other codes have no meaning to me as they are B codes and these would only show on a dealer diagnostic machine so iam surprissed you have managed to extract these codes ,so i assume you have visited a chinese web site to buy some of their lovely pirate software ,iam saving up for mine with the earnings from this web site
