change your oil and oil filter. Add a bottle of octane boost to the fuel tank then top off with fuel. Drive vehicle for about twenty minutes then have emissions tested. Unless you have a bad catalytic converter, you should pass emissions.

According to that website above, its your Accelerator Position Pedal Sensor. If you have already replaced it check your wiring harness.
Here is a website that for your wiring diagram for your 2005 Chevy Suburban.
Chevy of this model has to be driven 80-100 miles at least to reset the emissions this is if everything is good and all aspects pass and become active this will happen if all is well during the driving cycle each component will start coming on line.Remember to rate my solution this is how i earn my achievements also testimonial Thanks much in advance.
Wow, That has gotta be a pain. The Maf sensor regulates the fuel supply needed for proper air fuel ratio by telling ecu how muc air is moving thriugh the intake. Check it first, Then the TPS. Good Luck.
Your vehicle came with a smog pump. It may have seized up (probably breaking the fan belt) and my have simply been removed by a mechanic at an earlier time. It is located below the alternator on your vehicle. If there is no pump but a bracket to hold it, it has definitely been removed. Vehicles will often pass a state smog test without the pump. It only works during engine decelleration (when you lift your foot off of the gas pedal) Charlie
