Have Honda Questions? Ask a Honda Repair Expert.
Welcome to Just-Answer. My name is ***** ***** online handle is Honda-Man. I have over 31 years experience repairing Honda and Acura vehicles. I may need to ask some questions before I can give an answer. As much detail as possible is greatly appreciated.
Are you sure about the year of your Civic? I have been looking over the Honda technician site and can't find toes codes until some years later?
Could the codes be P1705 and P1706?
Sorry for the confusion. The codes you listed must be generic codes. Honda lists them as P1705 and P1706. Both are related to the gear position switch located under the shift lever console. I have include two articles on both codes that might help solve your problem. Most likely the gear position switch is bad. It's possible too that there is a wiring issue between the gear position switch and the engine control module. If you would like the diagnostic flow charts just let me know after providing a rating.

Did you have a chance to read the 2 articles? The code sets very easy it only takes 1 second for the fault to register and turn on the check engine light. You might not notice the lights change when it happens.
I have seen these codes before with what seemed like normal operation of the gear position lights.
Might be a ECM issue but so far I have never seen that cause the codes. Do you have a remote start or alarm system? I can send the troubleshooting info if you like. It's very thorough and should solve your problem.
I would appreciate a positive rating for the information.
Thank you, Cliff
Sorry for the delay.
What circuit board are you referring to? The flow chart will lead you to the cause if you follow the directions correctly.
Sorry but I am out of suggestions? Please wait for the next expert to reply to you after I opt out.
hi how can i help. if you can fill me in on were you left off.
may be a silly question but have you checked fuses? there is an ecm/cruise control fuse and if it blows it tends to only effect the transmission. and of course cruise control
ok just have to start with the basic i have seen many people chase trans issues on hondas and it ends up being that fuse. give me a few moments to look up some more info on these particular codes.
ok i did some research on that particular code. i looks to me that your park/nuetral switch is going bad. it may not be bad all the but that would explain the going between 3/4 too often and hard. i will find a diagram to attach so you can test this sensor. they are pretty common to go bad on a lot of vehicles. and reasonably easy to change.
i have attached a photo of how the switch operates. you will want to check for continuity on each position. make sure and check that that other positions do not have continuity while in another position. I.E. if you have it in 4 make sure 4th has continuity but no other position does. and wiggle the shifter a bit to make sure it doesnt have a dead spot while testing each position.
if everything has tested out normal i would be looking at the nuetral safety switch on the tranmission itself. i am having a difficult time finding a diagram of it but i will continue to look.
i am sorry i cannot find any clear diagrams. i would recommend changing the nuetral safety switch first before continuing. these transmissions also have problems with shift solenoids. but i would expect them to throw different codes than what you have.
