Code p0700 is TCM problem
code p 0722 is output shaft speed sensor--no signal===causes --wiring--OSS sensor --TCM ---ECM
possible that your problems are wiring and connections and /or transmission control module (TCM)

replace the input speed sensor to transmission and the wiring pigtail all are available at your chrysler dealer take your vehicle registration in to the parts counter so they have your vin # to get the right part and it is the front of trans by fluid linres to radiator.

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.

Ginko

SOURCE: where is the output speed sensor located for 2002 Hyundai elantra

The input and output speed sensors are located on top of the transmission, the output speed sensor is on the rear just under the brake master cylinder, the input speed sensor in in the center under the shift cable.

do you mean you changed the engine speed sensor for the auto box ? works off the engine rev's this is not on the same line as the rev counter it counts the rotations of the shaft spining.

Transmission has problem shifting have to put automatic trans into 1st to gett to go reads codePO731 on code reader any ideas?


DTC P0731 - Gear 1 incorrect ratio

Input and output speed sensors in the transmission are the most likely cause, They fail alot, relatively cheap to repair, if left ignored can burn up the transmission.

Good luck.

Hyundai accent won't move in reverse. It can go foward just fine.


on a hyundai you have a shifting sensor attached to the transmission that if it starts to go bad it will cause many problems, hard shifting, loss of power or no shifting.

1999 hyundai elantra transmition shifts from first to second but when im going uphill it doesnt go into third. already did a filter and fluid change and still no help.


Hi willie what you might want to try is pluse generators. these sensors send signal of the input and output speed of your trans and cause the trans to not shift from 2nd to 3rd and sometimes overrdrive. The 99 00 elantras are known to do this due to these sensors not working. hope i was a help.
