SOURCE: There are 4 codes I need to know about P0810,

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.

    SOURCE: trans code number automatic tranny 88 volvo

    Hello. i have owned many 740's, 240's, 122's, and 850's. I have done my fair share of transmission swaps. The transmission tag is located right above the trans-oil pan and directly below the od seloind on the drivers-side. if your volvo 740 is a non-turbo, the transmission is AW-70L, if it is a turbo-model then it is AW-71L. Good luck :)

    SOURCE: Error code P0785 on Volvo V70 XC -00. What's the

    P0785 - Shift/Timing Solenoid Malfunction (3-2 shift solenoid is not working properly)
    P1618 - Diagnostic Trouble Code (DTC) in another control module (in this case, in the Trans Module)

    Flush the transmission, get any software upgrades available, reset the adaptors and try it, nothing to lose.

    If it doesn't work you will need a transmission. Solenoids are internal, that's what controls the shifts.
    They could be faulty or the valve body but one should always do what I said once, if it doesn't fix it, you're looking at a transmission.

    The resetting of adaptors is crucial if you update the software. It's basically wiping the memory of the TCU (transmission controller) and teaching it how to shift properly again.

    Also could check this TSB...

    The reason why I ask, is because anytime there are MULTIPLE transmission solenoid codes, its usually the result of a failed ignition switch. However, since only two codes appeared and were one at a time, I think at this point, its unlikely the result of an ignition switch failure.

    P0785 is for the 3-2 downshift solenoid. Either the solenoid is faulty, or something got damaged while the 1-2 solenoid was being replaced. (connector knocked loose, wire rubbing on pan or valvebody, etc...).

    The 3-2 solenoid is #394 in the picture below, which is at the opposite end of the 1-2 solenoid.

    zjlimited_122.gif

    P0785 is for the 3-2 solenoid and that is 394 in the picture. Is it likely to fix it? yes, but of course I cannot guarantee that it will, sitting behind my computer and never seeing the vehicle.

    Hope this helps.

    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:

    ginko_125.gif


    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:

    ginko_124.gif
    The VSS are located on the wheel shaft. Here a picture:

    ginko_123.gif

    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.

Look for a pinched wire from the car being put on a rack or possibly an accident you may have had recently. If you can find no problems with the wiring or connections then it is time to see a professional transmission expert. It may just be that the transmission has an internal problem.

    I have a 2001 vovlo s80 with the codes p1618 p0705 po733 how can i fix


    PO705 is Transmission Range Sensor Circuit Malfunction. PO733 is Incorrect 3rd Gear Ration Information. P1618 means that the ECU and the TCM are not communicating properly. PO705 & PO733 can be related to P1618. Check the wiring going to the transmission. Look for a pinched wire from the car being put on a rack or possibly an accident you may have had recently. If you can find no problems with the wiring or connections then it is time to see a professional transmission expert. It may just be that the transmission has an internal problem.

    Engine light on for the past 2 years code p1618 and p1330 and p0751 will not allow me to pass emissions.


    ON THE 1618,MAKE SURE ECU CONNECTORS ARE OK,THE 1330 YOU HAVE A BAD WIRE OR COIL,THE PO751 NEED TO DO A TRANS FLUSH.

    Code p1618?


    This code indicates a communication problem between the engine and trans control units. When there is a problem with the trans, the control unit sends a signal to the engine control unit to turn the check engine light on. There is a problem with the that wire or corrosion on the control unit connectors.

    Check engine light car feels like its in high gear


    The problem is most likely a PNP(shift position switch) problem. When this happens, the trans goes into limp home mode. The trans goes into high gear and doesn't allow any shifting up or down. This is to protect the trans.

    What this code means is the trans is slipping, the most likely cause is internal parts failure or shift solenoid issue for 2nd gear, but based on what I know of this code you will end up getting the trans overhauled.
