I need the sensor connection diagram for the venom 400 for a 92 prelude

To identify venomous snakes quickly, without going too close, it helps to remember that they are fatter than harmless snakes, and usually taper at the neck and tail, while the non-poisonous varieties tend to be thinner and evenly shaped from head to toe, like a garden hose. Venomous snakes have a skinny neck and a diamond-shaped head, like a spade. They also tend to be more colorful, and aggressive. To play it safe, never provoke any snake; leave the area as fast as you can.

Test or check the crank position sensor. Look for the 5 volt reference signal (your prelude may have a higher reference voltage- I don't know), check that the ground wire is good, then see if you get a signal from the signal wire. See if you can back probe the signal wire with the engine cranking. If the sensor is at fault, the ecu cannot determine spark timing.

Look at a wiring diagram to see if the camshaft position sensor is also part of spark timing.

We do not have this diagram. The info is contained in the factory service manual and that is copyrighted and not free to share on the web. Sorry. I am told you can access the info for a small fee here: alldatadiy.com

heres adiagram to check resistance of the sensor, it should be1200-1300 ohms, but take note the sensor could read good at this time this problem is intermitent and the sensor may be bad, check for continuty at the computer connector , if all wires are good then i would replace the crankshaft sensor/top dead sensor (CKP/TDC).next check conntinuty between sensor terminals and ground check all four prongs on sensor if theres continuity on any one replace sensor, next key off and sensor connected . remove the pcm 31 pin connector (C) here a diagram of it. at the pcm connector measure resistance between terminals C2 and C12 it should be 1200-3200 ohms, then check between C3 and C13, again 1200-3200ohms if the ohms are off then check wires that fail omh test.next test is with connector again test connector c2 (blue /white wire) to ground and C3 to ground if continuity exists then repair wire that fails between connector and sensor, if all tests are good then try a good pcm. i dont think its pcm, i think if its not a wire then replace sensor , but good luck and i hope this helps.

The speedometer sensor is located on the top of the transmission. It is held on by one bolt. Remove the bolt and gently pull and turn the speedometer sensor and the whole assembly will come out of your transmission.


Park your Honda Prelude on a level surface, activate the emergency brake and place blocks behind the back tires for safety. Disconnect the negative battery cable with a terminal puller.

Raise the vehicle on the side of the wheel speed sensor's location. Remove the wheel and tire assemblies.

Disconnect the sensor electrical connection from the wiring harness.

Take note of the connection location for the sensor retainers, grommets and clips. You will need to know this information for the installation process.

Start at the connector end of the sensor cable and remove grommets, clips and retainers in order to free the harness.

Unscrew the sensor mounting bolt and remove the sensor from the differential housing.

Install the new speed sensor by reversing the removal process. Loosely secure the sensor and sensor harness connection in place, taking precaution to keep the harness from twisting or bending. Once in place, torque the sensor mounting bolt to 16 foot pounds (22 Nm). Tighten any bracket bolts to 84 inch pounds (10 Nm).

Lower the vehicle safely and reconnect the negative battery cable. Refer to your owner's manual to perform an ABS system check to confirm that you installed the sensor properly.

purchase or order a shop manual it will be well worth it when it omes to your wiring

The engine and emission control system covered by this information operate on a combination of vacuum and electrical signals; they are extremely prone to malfunctions due to improper vacuum connections. If a component does not receive vacuum at the correct time, it cannot function when needed. When working under the hood, pay close attention to the routing and placement of every hose.



Fig. 1: The vacuum hoses are usually numbered for easy identification

Hope this helped; TY for using Fixya (remember comment and rated this).

go to autozone or cal them they can give you the timing & rotation and fireing order

hope this is what you were looking for. let me know if you need more!

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.
