My speedometer reading is zero while driving. Checked the code is p0722 output shaft speed sensor has no signal.

Could anyone please tell me where the sensor is located? Many thanks! I tried to look it up but still have no clue of where it is. Must be hidden somewhere.

To access the sensor, you need to remove the air filter box. The sensor is on the top of the transmission housing. Here are the directions. The attached pics correlate with the directions.

Hi Joe,

Thanks so much for the quick and detailed response! I'll check it out on Friday (ordered a ratchet extension since the one I have so far is too short).

Another question is, is there a serial number or parts number to look for if I need to buy a replacement sensor? May I just use R18Z1?

Thanks again in advance!

Hi,

All you will need to tell them is the year, make and model. They will most likely ask for the engine size.

Let me know if I can help.

Take care,
Joe

Hi Joe,

a quick update:

After replacing the VSS, all the lights are gone, including p0722, p1747 and p1780.

Thanks so much for the help. This has saved me thousands of dollars since some folks from AutoZone told me that my transmission is not working.

Hello .. thanks for the donation .. much appreciated

You have replaced the sensor and the computer .. you will now need to check the wiring !!

DTC P0500 & P0501: VEHICLE SPEED SENSOR (VSS) MALFUNCTION

Test drive vehicle. Using scan tool, check vehicle speed. If correct speed is not indicated, go to next step. If correct speed is indicated, problem is intermittent. System is okay at this time. Check for poor connections or loose wires at VSS and PCM connectors. See appropriate wiring diagram in WIRING DIAGRAMS article. Repair as necessary.

Turn ignition off. Block rear wheels and set parking brake. Raise and support front of vehicle. Turn ignition on. Block right front wheel and slowly rotate left front wheel by hand. Using backprobe set, measure voltage between PCM 25-pin connector "B" terminal No. 20 (Brown/Black wire) and PCM 31-pin connector "C" terminal No. 23 (Blue/White wire). See Fig. 2 and Fig. 3 . If voltage does not pulse between zero and 5 volts or battery voltage, go to next step. If voltage pulses between zero and 5 volts or battery voltage, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM.

Turn ignition off. Disconnect PCM 31-pin connector "C". Turn ignition on. Block right front wheel and slowly rotate left front wheel by hand. Using backprobe set, measure voltage between PCM 25-pin connector "B" terminal No. 20 (Brown/Black wire) and PCM 31-pin connector "C" terminal No. 23 (Blue/White wire). See Fig. 2 and Fig. 3 . If voltage pulses between zero and 5 volts or battery voltage, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM. If voltage does not pulse between zero and 5 volts or battery voltage, check for short in Blue/White wire between PCM, TCM and VSS. Also check for open in Blue/White wire between PCM and VSS.

I would also check the junction connector in the right Kick Panel ... this may have been damaged by passengers feet !!

Hope this helps

When I first start the car and start driving, the speedometer sticks and bounces around 20 mph, no matter what my accual speed is. Once the car is warmed up, (1 to 2 miles, outside temp 50-60 degrees), It works fine from then on. I have already changed the Vehicle Speed Sensor, and checked for loose and fraid wires under the hood.

If the wiring is good and VSS is new, the speedo itself must be bad.

Hi, I have a '97 honda civic lx sedan, the speedometer, cruise and the srs doesn't work. I've checked all fuses an I'm wondering, does the vss need voltage or does it send voltage to the ecm?

Speedometer and cruise are related but the SRS is another different problem. It is related to the cruise only if the horns are not working, that would mean a bad clock spring reel under the steering wheel.

The VSS needs voltage and it sends a pulse to the speedomter and ECM.

It is a simple case of unscrewing old sensor and screwing back in new one .. you will need wrenches of course ? hope this helps

Hey TIMOTHY SHINKAROFF,

Which part of the harness did you replace?

I have attached the wiring diagrams for engine controls.

From this you will see there is a yellow/blue wire that goes to the PCM pin B10 from the VSS.

I have attached a description of the VSS function too.

Do you have access to a multi-meter?

Have you contacted Hondata regards this fault?

Regards, Joe
