Code p2101, what is the fix?

The P2101 trouble code in a 2007 Suzuki Reno relates to an issue with the electronic throttle control (ETC) system.

Here is how to fix the problem. Before you replace it, I would try a service because this can help the throttle body start working again.

Make sure you clear the codes once the repair is complete. Check out the images (below). Please let us know what happens.

I did everything that you sent me, and I am still getting the same code. I also noticed that the throttle plate wasn't moving when the accelerator pedal was being pushed. I started rechecking the wire harness looking for any damage, but I haven't seen any. I was thinking about just taking the engine wiring harness completely out of the car and take it apart and really look at it. I had found a couple wires earlier that had a bare spot on them, so I had fixed those. Could you tell me which wiring harness diagrams are better, one from a service manual or OEM wiring diagrams? I have the wiring diagrams, but they aren't all colored, I would like to get the wiring diagrams that are colored. Thank You for all the help, I appreciate it very much.

I would try replacing the throttle body if the wiring tests okay, cleaning the unit sometimes will not work. You don't need to remove the wiring harness to test the connections and to test for resistance to ground.

This guide will show you how, also here are the wiring diagrams so you can see which wires to test:

Here is the throttle body and engine wiring diagrams as requested. Check out the images (below). Let us know how it goes.

Ken,

I checked the wires and the TPS1, TPS2, 5-v ref, ground were all okay.

But the ETA and ETCB Did not have any readings at all.
Once again thank you for your help.

I have re cleaned the throttle body. I have re-checked and retested the TPS 1, TPS 2, 5-volt ref, ground and they all checked fine.

The ETCA and ETCB didn't get any readings at all.

Ken,

Here's a picture of my throttle body.

Yep, it is super clean, good job but you may still have issues internally even though it tested okay. I would check the wiring between the throttle body and PCM and if okay replace the throttle body. There is an outside chance the PCM is bad.

Ken,

I was wondering if I send you the live data from my code reader, would that help to try to diagnose which sensor is having issues or help figure out what is going on with my car? I have been looking at the wires that I can get too without taking the whole harness out to check the other wires that I haven't been able to get good access to. The wires that are on the top go directly into the ECM and I fixed one wire on that. The throttle body that I have is brand new. Do you think it's possible that something on it is bad or do you think it could be the accelerator pedal sensor? I replaced just the sensor and didn't replace the whole pedal assy but I have a used one that I tried and the voltages where the same as the one that's been in the car, so I didn't think that it was bad since the voltages and live data were exactly the same. I don't remember if I told you or not, but the car was running fine until the timing belt broke. I had the timing belt replaced and the pistons, valves, and rings and all the other things that needed to be replaced so when I got it back together is when the check engine light and the codes start to pop up. Also, it starts on the first try every time and as soon as it starts and runs for a minute the check engine light comes on. Any way sorry for such a long message. Thank you for all the help you have given me, I really appreciate it a lot.

Yes, live data would help. Trouble Code (DTC) P2101 stands for Throttle Actuator “A” Control Motor Circuit Range/Performance. So, this will be the wiring from the throttle body to the PCM or the throttle body itself, did you clear the codes after you found the damaged wire?
