The Speed Sensor is located on the transmission twoards the back, you can identify it by the two vacuum lines running to it from the frame area.
you possibly blew a fuse. it may not be related to you O2 sensor
None of the dashboard lights work on my 1988 Prelude. Why?
replace your speed sensor
Not without electrical work. The 1997+ Preludes have OBD2 wire harness while the 92-96 Have OBD1. Different wire harness/sensors/ecu.
any engine will work with a little mod or alot of mods i wouldnt do it 86-89 honda accord should work
The speedo itself or the wiring to the speedo can be bad. The Speedo and all the dash light flickers. Trans. slip, but when i unplug the speed sensor the trans work ok. I change trans. 2 times, speed sensor, alternator, battery. The problem not gone. I need help
I just went through that exact problem with my 88 prelude, it was the ignition cylinder.
One of the harder swaps I've seen done in a Prelude. Much custom work that has to be done, should not be your first experience with building a car.
will a h23a vtech work in a 92 prelude? what extra will be needed or changed besides a chipped p28 ecu ..? I have a 92' Honda prelude s.i. with a h23a1 non vtech and im going to swap, but i need answers before i buy this engine..
Yes, with some custom mounts for the engine and transmission. This can be expensive if you have a shop do the work for you.
The odometer gets its signal from the speed sensor, so if the (tailshaft) speed sensor is bad then the odometer obviously will not work
