I rewired to OBD-I for a b16a transplant into a 1990 Crx. I am getting code 17 and the speedometer is not working.
The car is bogging(hesitating) at low throttle and even at open throttle, and vtec doesn't seem to be kicking in. It is cable tranny for that motor.

Would a malfunctioning speed sensor create problems like hesitation or loss of power at full throttle?

Which year honda should I purchase the speed sensor for? And how easy is it to replace?

I appreciate any help you can give me.

 

i assume that you used the electronic vss. if so you need to put the d series vss in the b16 tranny

 

I do not believe it is electronic, I see the cable going into the tranny(not my clutch cable)....Would this code cause engine hesitation and poor performance?

 

well vtec wont work without a working speedo and if it worked before the swap and you didnt switch the vss at the time of the swap im almost positive you need to.

 

Thank you for your help.....I speedometer did work after the swap, it is just recently that with the obd-I conversion it is malfunctioning. I was told that there is a plastic clip that snaps on somewhere that isn't there and that my cable is coming loose or something and that is why it is malfunctioning.

I have a code 17 on my obd0 because my speedo cable snapped but it does not affect vtec or performance. I never heard of it affecting obd1 cars but im not 100% sure.
Vtec kicks in due to RPM's not speed

 

Well, Obd-1 does require a speed sensor for vtec to work, this I know. But I have read that the speed sensor also is responsible for adjusting the fuel delivery and timing of an engine based on its readouts for OBD-2 systems. Is this true of Obd-1 systems as well?

What could cause hesitation besides, spark plugs, wires, rotor cap, and timing?

not true. it wont kick in if you aren't going a certain speed.
what ecu are you running

 

p30

 

My car's accleration performance is horrible right now as well. The ignition wires are fine, the spark plugs are fine, the cap, rotor, and distributor are new. I haven't had the timing checked though. I just wondered if the VSS adjusted timing and fuel delivery as well as determined vtec's engage point. When the car is at a standstill it revs fine.....

 

Bump, bump bump, that's the sound of my 15's hitting in my trunk......

 

Come on guys, this is a simple question for an expert. Does the VSS affect your vehicles ignition timing(aside from VTEC) on an OBD-I B16A motor with a p30 ecu if it is not working?

 

Bump, bump bump, that's the sound of my 15's hitting in my trunk......

 

Ok, to answer the question that no one else knew the answer too apparently is that the VSS does not affect ignition timing or fuel delivery. My cam timing was just way off and that is why my car was accelerating like ****....
