06 avalanche problem codes are p0120 and p2135. Should I replace the top sensors on the accelerator pedal?

You can change the tps alone. You do not have to change the entire throttle body. It shouldn't be riveted in place, it should have screws or bolts on one side or the other. If it's riveted in place, use a dremmel and grind the rivets off. You can replace rivets with screws on the new unit.

Hi,
if you feel confident in using a digital auto test meter. Disconnect the sensor, and check the value range with the test meter to ensure it is within the set parameters.

However, before embarking on that task. Some ECU's will display a fault code, but will require re-setting to clear the code. With a new sensor fitted the ECU should re-set, although some "hold" the code in memory, it does not come up as a visible fault. Some vehicles can be driven a few miles, then the ECU will learn that the new sensor is within specs and will react accordingly.

SOURCE: 2004 chevy express van codes p0894

P0894 Transmission Slipping
P1258 Engine got Hot
P1516 Throttle Actuator Control (TAC)

Chevrolet Tahoe vehicles may experience a performance issue where they will not go over 15MPH. The vehicle may appear to be in "limp-in" mode, giving just enough power to get you to a shop. The codes indicate a problem with the throttle position sensor circuits and throttle actuator performance. Do NOT start replacing parts. Shops report a pattern failure in the electrical harness to these sensors. Chevrolet has issued a revised replacement harness to correct the problem. The original connector was prone to vibration and broken wires that disrupted the signal to the PCM and put the vehicle into reduced power mode.

SOURCE: Is there a way I can reset my computer in my 2006

yes. disconnect the battery COMPLETELY and let it sit for a bit(30 minutes) hook it back up.

SOURCE: I have an 03 Tahoe 4.8 liter I'm getting OBD codes p0120 p0220 p 1516 p2135 please clean the throttle body replace the throttle body with the position sensor my car will not start

code p 0120 refers to mass air flow(MAF) sensor/volume air flow(VAF) sensor---low input===causes wiring short to ground ---MAF/VAF sensor---ECM
code p 0220 refers to throttle position sensor (TP) B /accelerator pedal position (APP) switch B--circuit malfunction===causes --wiring--TP/APP switch---ECM
code p 2135 refers to the same as p 0220 causes and sensors
