I have a 2000 Acura Integra LS swapped a year in a half ago to a B20B I never had any problems until 2 days ago when I was on the street. I noticed first that the speedometer on the right of the cluster dropped to Zero. The car was running fine but when I stopped and a turn left only lane as I gradually increase speed I notice that the gears was not shifting right kinda like a hesitation of what not kind of shifting, I can't really explained the way the car was acting but probably someone here knows what I am talking about. I also noticed that my D4 light was blinking, car so far is running fine but in my mind I want to make sure I am doing the right steps in resolving the issue. So far I replaced my Speed Sensor with a aftermarket sensor but still has this weird irratic speedometer that sometimes goes up down or just plain stays at zero especially on the freeways. What else options I have to resolve the issues please help.. Thanks

 

ecu

 

I think in the manual if it says it's blinking the tranny is ****ed?
I can't remember for sure. Look in the manual though.

 

-tranny seems okay and real smooth but its a debate whether is still the sensor is faulty or if the ECU is giving out.. something to really research. I swapped out the tranny into another integra and works wonders..

 

Swap the ecu then and that will tell you if it is either the ecu or the sensor.

 

clean and reattach your engine bay grounds i had tons of trouble with a bad ground. d4 blinking and rough shifts galore. i swapped ECU and still had the problem. look up my old threads for more details.

 

my friend gotta gsr swap in his ls and the ls still has the auto cluster.
that light blinks lol
