I have a 94 Honda Accord EX 4dr and m speedometer stopped working first it started going u and down then stopped then started back up now it has stopped. My car s a automatic an the D4 light is starting to blink even when it is not in drive. Another thing how would it be if I put a AEM V2 cold air intake with a throttle body spacer and change the exhaust how much power would I see? Or is that just a waste I have the V-TEC motor and What is the difference in the F22b DOHC and the H22 far as a swap which would be better? Sorry for so many questions back to back I just got the car and see that it is alot that can be done to these cars and I see that everybody is doing Civic's and not to many Accords my year is there a place that has Accord pics and mods? Can anybody lead me in the right direction? Than You

 

probably your speed sensor.
next with those bolt-ons maybe 10-12whp
f22b is a dohc 2.2 like the h23 but smaller bore.
h22 is a dohc vtec

i use to have one the same thing speed sensor for the mods intake headers cat back exhaust ull feel the diffrence throw in a cheapy vtec controll and that will make all the diffrence in the world get one on ebay for about 70 bucks

 

next time, please use a more descriptive title that best describes what the thread is about. It'll help bring people into your thread and also help when people are searching for similar problems.

also, please keep the thread to one set of questions. Meaning, dont ask about a problem you are having with your current engine or suspension and then switch to asking about which swap is better. The thread can take a different direction than you want and some of your answers may not get answered.

it's always best to search before posting and then if you cant find what you are looking for then post.

 

My car had the exact symptom two weeks ago. After changing the VSS, the car is running well. I bought the VSS from eBay at the cost of $19 included shipping and handling.

 

Can you tell me where the VSS is located on the car I can't seem to find it??

 

It is on the top of the transmission house and close to the firewall. Look down under the intake air duct, you would be able to find it. You will need to remove the intake air duct when trying to replace it.

 

Before decided to change the VSS, I also read the code from TCU. The code is 4 that directly points to VSS problem.

 

takes about 10 minutes to change its really simple
