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.

Your heater core is leaking. The smell and smoke is from the coolant evaporation.

SOURCE: volvo s70 radio code

You must take the car to a Volvo dealer so they can reference the code from the VIN number. If you call it in, they only assume you stole the radio. Sometimes you have to prove you own the car.

SOURCE: 1999 volvo radio code

To reset the radio you have to leave the key in position one (the radio will come on, but the dash lights are not on) with the radio on for at least two hours. It can take up to four hours to reset.
Make sure the climate control and blower are in the off position to keep the battery from running down. Eventually the radio will say "code". There is a four digit code that is unique to each radio, if you don't have it you must contact the local Volvo dealer and have your VIN code. The VIN code is locate on the far top/right side of the dash, you must be outside the car to see it. It will begin with something like YV1LS...................

When you get this code from the dealer you input the code using the radio preset (1-6 buttons). If the radio says code again that means it is the incorrect radio code. Most likely the radio has been replaced. Then it would be alot easier to take it to the dealer since the radio has to be removed and the serial number taken off the radio chassis unit. Usually most dealers will do it for free if they think you'll come back for services, so just tell them you just bought it and be nice, hopefully it will work.


hope this helps

Have 2009 impala ltz shuts down going down road pull over have power but starter won't engage


The starter is computer controlled by way of a relay ! When you turn the key to the start position a low voltage signal is send to the BCM - body control module , the BCM then sends a message over the GMLAN serial data network to the PCM for starter engagement , The PCM energizes the starter relay sending B+ voltage to the starter solenoid ,if there are no anti-theft system problems. The codes you have listed are emission related codes !
DTC P0455: Evaporative Emission (EVAP) System Large Leak
You must mean P0442 , because there isn't a code P0422 .
DTC P0442: Evaporative Emissions (EVAP) System Small Leak Detected
None of these would cause vehicle to shut down > Your best bet would be to take your vehicle to qualified repair shop an have diagnostics run on it .

Po133 is and oxygen sensor code. Replace the front oxygen sensor use a bosch or OE sensor only. P0442 is and evap system leak. Most common fault is a cracked hose at the evap cannister at the right rear of the car.

"I have 1998 Volvo V70 AWD and my check engine light is on. I changed gas cap that one I got from the Volvo. Also I done smoke test few days ago, the mechanic couldn't find any leak. Now it show the code...


1--Evap system hoses
2--Purge Valve
3--Check Valve
4--Air pump
5--Canister valve(some people call canister purge valve)

A crack in an evap hose is the most common thing. I would definitely check the two evap canister hoses. These are easy to fine, one being the J hose, which is in a J shape, and connected to your canister and the other end to a valve. Then the Canister Evap hose, which is 18" or so long with a 4" L on the end of it. It connects to a hard plastic or metal hose that can easily be reached by removing the rear passenger side tire on a 98 S70 turbo. Check these 2 first. I found that the cracks in both of these hoses were where the clicks were or close to them(many old style clips causing this). Check these too, again they will both be connected to the canister valve that is right beside the charcoal canister on the passenger rear side.

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.
