Show how to replace a throttle position sensor in a 1999 volvo S70 five speed non turbo 2.4 dohc

Throttle position sensor is part of the throttle body assembly. It is not sold as a separate part. You need to replace the throttle assembly. Remove the intake tube, remove the 4 bolts and disconnect the electrical plug. It will need to be programmed by someone withe the Volvo Vida software.

Where is the output speed sensor on my 2000 Volvo S70 ? It seems to have brake and trans problems. The front brake would act like it was trying to apply the brake while driving down the road. The trans was...

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.

Hi I want to know where is located the vehicle speed sensor. for a volvo v70xc 1999

If you will remove the engine air filter box, the speed sensor should be located directly on top of the transmission and is easily removable.

Speedometer not working

This is not a cable system. You will ned to get a scanner to see if maybe the speed sensor is bad or a code is stored to diagnose. It could be a bad sensor, broken wire, or the instrument cluser may be bad.

Spedometer not working in the S70

speed sensor on transmission are often faulty on this model, check with scann tool, if you have a speed reading on the tool but not the dash then it is the speedo itself that is bad
