Speedometer quits working and D4 light flashes on 1995 Honda Odyssey. The Vehicle Speed Sensor (VSS) is bad. You will need a replacement ($39 online) sensor, Ratchet with extra long extension, 10 mm socket w/ swivel, a long flexible wand with a magnet on the end, and a flashlight. Unplug the wire from the old VSS. Remove the two mounting bolts. Lift out the old VSS and the drive key. Put a small amount of grease on the new drive key and insert it into the new VSS. Plug the wire into the new VSS and use the wire to lower the VSS into place aligning it with the two mounting holes. Use the magnet wand to lower the bolts into the holes and turn to just get the bolts started. VSS IS FLUSH WITH THE TRANSMISSION BEFORE TIGHTENING THE BOLTS. You are now finished. You can access the VSS from the top of the engine in your garage/driveway. It is located on the top/backside of the transmission, just below the air cleaner hose. Best done in the morning when the engine is cold unless you like getting burns on your forearms. Good luck!

Someter dosnt work code p0500 when code cleared eng light comes on as vehicle shifts into 2nd everytime same code reoccures


code p 0500 refers to vehicle speed sensor(VSS)--circuit malfunction===causes --wiring--VSS --- ECM
engine lights report on both engine problems and transmission problems
check all wiring connections to the transmission
the VSS reports to the transmission control module, the road speed and that is when the TCM knows when to change ratios
At this point I would be closely checking the wires and harness connections and then replace the VSS

Ihave nissan quest 2005,have code p0500,but this transmission have two sensors,Im no sure what the speed sensor


code p 0500 refers to vehicle speed sensor(VSS)--circuit malfunction===causes --wiring VSS---ECM
it has only one VSS and if the wiring is good with good connections replace it
there are other sensors in the transmission so don't confuse them with a VSS

HOW TO TEST A TRANSMISSION SPEED SENSOR


to check VSS operation back probe two terminals of the vss connector using voltmeter probes.you can check VSS sensor while still in vechicle.to check vss sensor connect voltmeter probes to vss sensor two wire terminals set voltmeter on the AC scale turn on the ignition to on position rotate front wheel by hand watching voltmeter vss sensor should produce a minimum of 0.5 volts and the voltage should increase as the transaxle out put shaft rotates faster.

A defective vehicle speed sensor may cause different problems depending on the computer output control functions. A defective vehicle speed sensor (VSS) may cause improper converter clutch lockup, improper cruise control operation, and inaccurate speedometer operation.
  • Prior to VSS diagnosis, the vehicle should be lifted on a hoist so the drive wheels are free to rotate.
  • Backprobe the vss output wire and connect the voltmeter leads from this wire to ground.
  • Select the 20-volt AC scale on the voltmeter.
  • Then start the engine.
  • Place the transaxle in drive and allow the drive wheels to rotate. If the VSS voltage signal is not 0.5 volt, or more, replace the sensor.
  • When the VSS provides the specified voltage signal, backprobe the VSS terminal at the PCM and repeat the voltage signal test with the drive wheels rotating.
  • If 0.5 volt is available at this terminal, the trouble may be in the PCM (powertrain control module).
  • When 0.5 volt is not available at this terminal, turn the ignition switch off and disconnect the wire from the VSS to the PCM.
  • Connect the ohmmeter leads across the wire. the meter should read zero ohm.
  • Repeat the test with the ohmmeter leads connected to the VSS ground terminal and the PCM ground terminal.
  • This wire should also have zero ohm resistance. If the resistance in these wires is more than specified, repair the wires.
  • The condition of a speed sensor can be checked by going through the diagnostic routines for the system.
  • If this test indicates that a sensor is faulty, the sensor should be replaced.
  • Speed sensors can also be checked with an ohmmeter. Most manufacturers list a resistance specification.
  • The resistance of the sensor is measured across the sensor's terminals.
  • The typical range for a good sensor is 800 to 1400 ohms of resistance.

Hi.

In ordinary conditions the engine replacement should not result in VSS error. TI could not find any bulletin about ECM (the car main computer) reprogramming after engine swap but the VSS signal passes through two modules, the ABS and the ECM. If you have replaced the engine you may need to re-flash or re-program the ECM . There are a couple of forums where users complain about the same problem.The job can be done at the dealer place.

Before reprogramming the ECM do the regular troubleshooting for P0500. The problem could have been already there before the engine swap, the VSS or the VSS wiring may also have been damaged in engine replacement operations. Check the VSS mounted on transmission, Ohms are between 500 and 700, check also volt output on bridge. Check VSS wiring to ABS module and ECU and check the two-wire connector to VSS (check volts) . Check ECU connector. Check PNP switch.

Regards.

When driving the car the speedomator goes to 0 and then the tranmission starts slipping


There's a possible worn out clutch inside of the auto transmission. The speedometer going to zero could be the transmission not sensing speed, and then disengaging the transmission to keep the car from stalling at a stop sign, maybe.

Try looking at the VSS (vehicle speed sensor) circuit on the transmission.

Here are some tests that can be performed on the VSS:

Locate VSS lead wire from engine computer of 2001 GMC Jimmy 4WD


On connector c2 red conector-terminal #21 purple with white stripe is vss high signal wire---terminal #20 light green wire with black stripe is low vss signal wire-----I don't know what you are going after poss no vss for speedo inop or abs code for rear speed sensor erratic??? there are two sensors on top of transfer case right & left side both same interchangable parts swap them out for diag most likely problem is wiring at sensors poor temial fit you can order new connectors at dealer & solder them in also some time wire rubb through on top of trans GOOD LUCK

Check engine light reports VSS problem


A specific trouble code,no matter what the code is,always has a diagnostic route that is available at pay sources like All Data online.It always involves checking the wires involved in the specific circuit,for continuity,along with testing the individual components,like the vehicle speed sensor.Remove the VSS from the trans,and reinspect the drive,and driven gear.The drive gear is attached to the differential down in the trans,and you have to actually look down in the hole,and verify the drive gear is ok and intact.Then look very carefully at the plastic gear that is attached to the VSS,and make sure the middle of it isnt "applecored" as this will cause the VSS to NOT turn or give a signal.Now,reinstall the VSS,and turn the differential.This requires two helpers,one on each side of the car,to turn both tires at the same time,in the same direction (this turns the differential) while you are checking the two wires coming out of the VSS,for an alterenating current flow,that would be sent to the PCM(ECU).Verify VSS operation.If the VSS is producing a signal for the PCM,then the only thing left is the PCM itself,or the wires between the VSS,and PCM(ECU).That goes back to what i was saying about checking the wires' continuity between the sensor and PCM.Make certain the wires involved in the VSS circuit have continuity,and good tight connections at both ends.Good luck.
