I had recently replaced my TPS sensor in my 2000 Honda Civic EX and it was running fine before everything but once I replace the TPS sensor with the new one it made the car idle really sluggish as im trying to drive the car and get it through the gears. It is manual. Mechanic's Assistant: Which particular sensor are you asking about? And have any trouble codes been triggered? Is a TPS throttle position sensor. Mechanic's Assistant: Are you fixing your Civic yourself? What have you tried so far? I have not hooked up a computer to see if it throws any codes. And yes I'm trying my hardest not to send it to a shop because I've been spending a lot of money sitting into a shop when I have all the tools at the house. I'll give you the rundown. Before I changed the TPS sensor the car was running fine with no sluggish feeling whenever I went to drive it however whenever it is sitting in park with the e-brake pulled it idles fine but whenever I start to drive the car is when it gets sluggish and acts as if it want to die. I was having problems with my Skunk2 carburetor that was hanging or (staying stuck) I called Skunk2 directly tell them that the carburetor was messed up because I read online and that is what it had said about that carburetor. After I gotten hold of them and spoke to one of the ladies there she had told me to replace replace the TPS sensor first so I did. Once I replace the TPS sensor all my problems started and I don't even know where to begin next sat out for hours trying little things here and there adjusting the idle screw adjusting to stop screw for the plate all kinds of stuff Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? No, I think that it .

Howdy from Tennessee, I'm Chris aka Moose. Who am I helping today? I'm glad you've come here to get help. I will do my best to get the answer you are looking for. I help many customers, so sometimes my replies are delayed, I will respond once available. I try to be online at 1-5 pm and 10 pm-5 am every day. I am not really sure what this is Skunk2 and your car does not have a carburetor. It uses fuel injection and throttle body. The TP sensor should never be replaced, it is specially timed to the throttle body. If the TP sensor is bad, the throttle body should be replaced. You mentioned you have adjusted the throttle stop screw. It may now be incorrectly adjusted. Unplug the IAC valve and get the vehicle running. Adjust the throttle stop screw so the engine idles at 500 RPM. Then plug in the IAC valve. I then recommend these steps [https://www.dropbox.com/s/r2cimvb2blyqgnj/Air%20Fuel%20System%20Service.png?dl=0](https://www.dropbox.com/s/r2cimvb2blyqgnj/Air%20Fuel%20System%20Service.png?dl=0) If the concern continues, then replace the throttle body with TP sensor and make sure no codes are stored for other issues. Thank you for seeking us for help, I hope I provided what was needed. Press reply if you need to follow up. If you liked my answer please let me know so I can mark your question complete. Moose

Hey moose it's great to meet you in great to hear from you! I really do appreciate! . My name is \*\*\*\*\* \*\*\*\*\* I have been having a lot of troubles with the car since I've replaced the TPS sensor I just got off the phone recently with a gentleman with just answer because I forgot to add in that when I bought the car it was swapped out for a B20 motor I believe it's a b20b to be exact. And yes you are right I meant to say Skunk2 throttle body not carburetor. I am actually going downstairs now to go over the process the you were recommending. I did want to give you the whole Rundown, just so nothing jumps out. Before I replace the TPS sensor, the throttle body was hanging open. Nothing terrible, I would always be able to get it back closed by tapping on the throttle. But that is the reason I begin to replace the TPS sensor because that is what they have told me over at Skunk2. I have replaced the throttle position sensor with part number 911 - 753 that is the one that called for the b20b. After I replace the TPS sensor I had also tried a couple of different things I'm not for sure if any of these would get in the way but I unplugged of course the negative on the battery which probably won't be anything but I also unplug the ECU that way I could try and reset everything. I'm going to go over the information now that you sent me thank you so much for your

Sorry for the delay I'm just getting around into the car after taking a nap. The car is idling at this set idle with the iac valve connected. I can't seem to get the car to stay on or run when I unplug the iac valveI'm not for sure exactly what line is 500 RPMs I've heard different things from every oneOkay I actually take that back. I was able to get the car warmed up enough to where it would run without having the IAC valve connected
Automotive Expert
Each tick mark on the tachometer between the numbers is 100. So 500 RPMs would be 5 tick marks below the number 1. You will need to play with the throttle pedal or linkage to get it to run and stay running with the IAC unplugged. If it will not run then adjust the throttle stop screw in more. I will be offline in 15 minutes to get other things done.

Okay sounds good! So I unplug the IAC valve and adjusted the stop screw to where it was just right there at 5 to 600 RPMs and then plug back in the IAC valve and it went back up to a 1000 rpms. I went ahead and adjusted the TPS sensor back to .5 volts closed and 4.5 volts opened fully but I can only get 4.65 to 4.7 fully opened
Automotive Expert
After all these adjustments have you cleaned the computer memory by holding the battery cables together for one minute?

I haven't gotten to yet drive it a hundred miles I wasn't sure if that was some important or notI was actually going to ask you don't need to change the fuel filter before or after cleaning everything out
Automotive Expert
The 100-mile thing is to give the fuel injector cleaner time to actually work and clean the injectors, and engine internally before you do a reset to make the engine computer relearn. You can change the fuel filter now or later. It should be done every 30k.

Okay I will definitely keep it for future reference. Would me not doing that with the battery cables have it run faulty like that was how I would explain it to you
Automotive Expert
The computer learns as you drive. When you replace a part, the computer needs to relearn from scratch or it will think it is running no different than before but in fact it is because parts were replaced.

Okay I'm about to try and do the seafoam but I wanted to make sure that I had the right hose

Customer attachment 12/31/2020 9:14:06 AM

Is it the one leading to the brake booster
Automotive Expert
That hose will do fine.

Okay and just want to ask is there any chance that there would be a fuse that would possibly be blown out that would signal to the motor or anything like that properly run right or something that would make it sluggish while driving and feels as if its about to die. I do apologize for such a long conversation and hassle!I just changed the fuel filter and about to run the injector cleaner and seafoam through and then take off the throttle body to clean it and see how it runs but when I change the fuel filter it still runs sluggish and didn't help anything. It's just so weird because the car was running perfectly fine before any of thisAlso I remember you mentioning if any of this doesn't work that I would have to change and buy a brand new throttle body and TPS sensor and that's just the thing. The throttle body that I have on the car is brand new and I had bought it about a year agoI'm not sure if that would be necessary or not or if I could possibly get a hold of Skunk2 and have mine replaced because it was hanging and that is what got me into this situation at first
Automotive Expert
This concern should not be a fuse issue. Warranty replacing the throttle body is most likely what is going to be the end result repair.

Okay awesome deal I am all finished up and this will be the last for me LOL. I was wondering if you knew what wires and plugs I would need to get for the b20b so I don't miss match anythingI got some last night but forgot to get them for the motor that it calls for and not the year of the car because my car was swapped out with a b20b in the wires that I got right now don't look the sameIt's so confusing looking for parts for the b20b because I'm not for sure if I need to look for the part for b20b or for the part on a 2000 Honda Civic EX. This is all new to me I've never worked on the four cylinders or anyting fuel injected to say. When I looked up what motors did b20b come out as says 96 or 2000 CRV what else would I be looking at or what else would be changeable for the b20b. What year model and make would I look for
Automotive Expert
What is a B20B?

2.0 instead of the original motor that comes with the car which is a 1.6 liter
Automotive Expert
When ordering parts those parts need to be for the engine that is in the car or by the vin# \*\*\*\*\* the engine is the original one that came in the car.

Okay awesome deal! I got done with everything and random process but no luck unfortunately it was still running very sluggish. It sounds like it has a vacuum leak. I just wanted to say thank you again for all of your help and wishing you a happy New Year!
Automotive Expert
Happy 2021 to you as well. I believe a replacement throttle body with an already attached TP sensor is still needed to address this.

I'll definitely contact Skunk2. I actually think it might be a [head gasket](/topics-head-gasket-honda/) issue because whenever I was changing the spark plugs and wires there was water on the end of the spark plugs and corrosion inside where the plugs go.
Automotive Expert
A compression test is needed to confirm that.

Okay ill see what we cant do with skunk and go from there.
