    yes im sorry how doi fix the codes

  • rcdhouse3 May 25, 2009

    acording to the haynes manual the tps is on the right side and when you look at the throttle body that comes with my truck it only has one 8 pin plug on the left side and the piece the harness plugs in to is riveted on to the throttle body can i change the tps under that or do i have to get a whole new throttle body if the yellow wire is not my problem. thank you .

  • rcdhouse3 May 25, 2009

    I took some piks of my throttle body to show ill try to show you them. they came out to big ill have to email them to you

  • rcdhouse3 May 25, 2009

    do you know of a parts house with realy good prices.

  • rcdhouse3 May 25, 2009

    i checked the wire the yellow one realy close and i went to the local autozone and reset the check engine lite time will tell if it comes back on . the piks i took will show the ploblem of the tps the part is a three pin and 2 bolts but there is nowhere on my throttle body to put that part and the haynes manual dont say anything about drilling out any rivets .

  • its420_us May 11, 2010

    All 4 of your codes are related to your, "throttle position sensor". Your "throttle position sensor" is bad, and it needs to be replaced.

    Do you have a question?

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.

    You should get your new tps, before you do anything, so you know you're removing the correct part.

  • its420_us May 25, 2009

    One more important tip, before doing anything electrical, DISCONNECT YOUR NEGATIVE BATTERY CABLE!

  • its420_us May 25, 2009

    After your repair is complete, take it to autozone the will reset your codes for free.

  • its420_us May 25, 2009

    It's hard to say who will offer you the best price for the part in your area.

I dont know by what you wrote if the vehical is running or not but I will assume not and tell you what to do first. When you are standing infront of the vehical the wiring harness that goes to the tps left side of throttlebody pull on each wire specialy the yellow one , look at each wire very closely if they are not smooth round and perfect the wire is broke under the coating. look at those wires very close going to that throttlebody right at each plug . I mean with in 1 inch and closer to the plug. check real good is that yellow wire broke? I have had a few of those wireless tbi's sent to me after shops gave up and looking at wires normaly you cant tell but they break like the yellow wire mainly. Also GM has revised the whole unit and they recommend replacing it with the new revised unit.

    I have never just replaced the tps gm has revised the whole unit. you have to first check those wires on the left side remove loom and tape if you have to. look real close for the yellow wire or anyother that look damaged . the wire mainly the yellow will break under the plastic and fixxing that will fix with out replacing anything. please check those wires next to the unit at the plug. check them good i bet you will see one is broke. otherwise if not by some chance that whole unit has to be replaced

    Hi I looked everywhere last night for you and found something that will help . google all lower case : gm broke wire at tps , then scroll down until you see " reduced engine power message" click on that and please read each one. it will give you the part # of the pig tail you need and it will explain about the tps and it is a whole unit. but go their read them . here is another thing check voltage on each part of the yellow wire right at the plug then 2 inches down so forth. let me know

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

I need to know the code po120


Throttle Position Sensor/Switch (TPS) A Circuit Malfunction
The TPS (Throttle Position Sensor) is a potentiometer that is mounted to the throttle body. It detects the throttle blade angle. As the throttle blade moves, the TPS sends a signal to the PCM (Powertrain Control Module). Usually a three wire sensor: A 5 volt reference from the PCM to the TPS, a ground from the PCM to the TPS, and a signal return from the TPS to the PCM. The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is outside of normal operating range, P0120 will set. NOTE: The PCM knows that any large change in throttle position means a cooresponding change in manifold pressure (MAP). On some models the PCM will monitor MAP and TPS operation for comparison. Meaning that if the PCM sees a large percentage change in throttle position, it expects to see a cooresponding change in manifold pressure and vice versa. If it doesn't see this comparitive change, P0120 may set.

The reduce engine light comes on at 50 mph what could the problem be


DTC P0120 P0220 P1516 P2135 these should be the problem codes.
2003-2006 Chevrolet Avalanche, Corvette, Express, Monte Carlo, Silverado, SSR, Suburban, Tahoe, Trailblazer. for reduced engine power. p0120 is throttle position sensor, ( tps ). p0220 is relates to tps, p1516 tps is out of range. p2135 is a throttle body code, the throttle body needs replaced. but before you do it replace tps first to see if it takes care of the other codes. have a good day !!
