Grounding issue "Circuit low" = ground wire problem or another system on the same circuit using too much current.

Check all wiring issues and then correct the issue to have the code go away :)

SOURCE: where is the output speed

Hi.

The problem is either vehicle speed sensor or wiring harness going to sensor. In some case the ECM is defective.

Ensure that you have already replaced the VSS with good ones.

If you have not replaced them yet, then the sensor can be tested reading the waveform. This is done connecting both VSS input and output wires to a machine. The one below is a good VSS wave at 37 mph:

If the waveform is incorrect, the sensors must be replaced, as the ECM returns P0722 when VSS output is incorrect, or when there is no output.

A second test can be done reading the sensor impedance and voltage. Connect a multi-meter to the sensor. Set first on Ohms reading (impedance). A good sensor will read 560-680 Ohms at 20C (68F).
Set multimeter on Volts. Touch rapidly the sensor with a magnet and pull magnet away. The sensor will emit a weak voltage pulse. If that does not happen, then the sensor is broken. Ensure that multimeter is on high volt scale.Voltage will be quite low:

The VSS are located on the wheel shaft. Here a picture:

The VSS is connected to the ECM.

If you have already replaced the sensors you need to check the wiring harness to the ECM.

ginko_122.gif
The wiring harness is tested checking that each wire going to the ECM has continuity. This is done reading impedance between each connector in the sensor , and the respective connector in the ECM. Impedance must be zero or a very low value. If it reads infinity, then the wire is broken.
A second test is done reading impedance between the two different wires at ECM connector. Impedance must be the same as at VSS contacts on sensor. If impedance is zero, then there is a short. Ensure that you choose a proper Ohms scale while doing the test.

If you have already replaced the VSS, repair or replace the wiring harness. The ECM failure returning this code is very uncommon. At most you may have a defective ECM connector.

Regards.

Hello and welcome to FixYa!
As a first course of action, I strongly suggest that you remove the positive battery connector and let it sit for atleast 10mins. or more before reconnecting it. This will reset the system and can get rid of the dash lights.
If the problem still persists, I suggest that you take it in to a reputable shop to have it resetted manually.
Hope this helps and thank you for using FixYa! Have a good one!

P0722 FAULT CODE


P0722: Transmission speed signal missing.

There is a turbine speed sensor that detects and reports the speed of the transmission shaft to the computer to help determine shift points. Sometimes this duty is shared by the VSS (vehicle speed sensor) but if your speedometer still works, then the VSS is good and you should replace the TSS (turbine speed sensor). I would guess you are either stuck in 1st gear all the time or your transmission shifts erratically.

I put the computer on my volvo v70 n i have this code ..p0460,p1618,p0722,p1550 and i like to know what r they and how can i fick them cuz i need to pass the inspection to get it register . in the dasboard...


Per other sites I've seen these 2 codes p1618,p0722, are your ABS module. It can be taken out and re soldered and will work fine. Many Volvo mechanics know how to do this or you can find a repair service on Ebaymotors possibly. My guy charges me $150. Supposedly you can even drive the car without the module installed but you won't have abs so don't expect to stop as you usually would with a correctly working ABS. Your tires will now skid old school instead of the abs module taking over and pullsing your brake pedal, etc.

There are 4 codes I need to know about P0810, P1132, P1618, and P1633, 2001 Volvo V-70 24T


810 neutral check, incorrect connection
  • Check the transmission and control module connectors. Check for contact resistance and oxidation according to Checking wiring and terminals. Permanent faults
  • 1132 front o2 sensor signal too high
    1618 dtc is in another module
    Volvo does not provide information regarding DTC P1633 for many of their models.
    However, it has been reported that various Volvo engine control modules will produce this code. The code is associated with a missing or inaccurate vehicle speed signal from the ABS control module and may be accompanied by DTC P0722 or P1618.

    Possible causes:
    - Defective vehicle speed signal to the ABS control module
    - CAN connection problem
    - Defective ABS control module
    - Defective engine control module

    Manufacture codes associated with this P code may include ECM-510f, 530d.

    I have a 200 Volvo s80. last week when my wife started it, all the lights came on... stc,brake failure, check engine light, brake light..they all are on and i cant seem to find the problem.. can someone...


    I have a similar problem, I am going to assume that most of the lights have gone out and you are left with the check engine and a transmission service message. Check the OBD for the error codes and see what they say. If they are P0722, P1618, P1633 it is likely your ABS module. This module appears to have a life span of 5 years to 80,000 miles average before it needs to be replaced. Other symptoms of a bad module would be that the ABS light comes on while driving down the road. Than goes out on the next engine restart or two. Victor Rocha is reconditioning ABS modules for $125.00 and upgrading them to better than factory. There are instructions on the web of where and how to remove the ABS module. This is better than the dealer's new module for $995.00 plus installation.
