P0700 p0720 codes. dodge stratus 2002 "jumping" speedometer drives erratic. sometimes sticks in 2nd gear. I've replaced output speed sensor to no avail. whats my next step?
Check the wire harness, make sure there are no breaks or crushed wires. Also check the wire harness to the TCM, look for any loose connections. Good luck and keep me posted. Be glad to help.

While the code could have set because of a wiring or connection problem, it's almost surely the sensor. Input speed sensor failures are not uncommon.
The input speed sensor is mounted right on the front of the trans directly under where the cooler lines attach. It threads directly in and has a 1" hex for a socket for removal. If the wiring and connection look visibly ok then I would recommend replacing the sensor
input and out put speed sensors tell the TCM and the ECM the difference between engine rpms and transmission input roms so that the correct gear ratio can be selected
A speedo sensor reads the out put shaft (drive line ) shaft and refers to road speed for speed and odometer readings and to calculate the fuel consumption rate
it is possible that you have replaced the wrong sensor
Talk with an accredited transmission specialist shop and have the problem diagnosed
P0700 Transmission control system malfunction
P0720 output speed sensor circuit malfunction
P0731 gear ratio error in first gear
P0732 gear ratio error in second gear
P0732 Gear 2 Incorrect Ratio P0720 Output Speed Sensor CKT Malfunction P0736 Reverse Incorrect Ratio P0500 Vehicle Speed Sensor Malfunction P0700 Trans Crt l System Malfunction P0731 Gear I Incorrect Ratio
P0455 = Evap leak monitor large leak detected. This code usually means the gas cap may have been loose or needs the rubber gasket.
P0500 = No vehicle speed sensor signal. Vehicle speed sensor is located on the transmission near one of the axle shafts (it may need replacing).
P0700 = EATX controller DTC present. This simply means you have transmission related codes.
P0732 = Gear ratio error in 2nd gear. This code is of some concern, it means the transmission is slipping in 2nd gear. However the trans may be in limp mode due to the speed sensor code (limp mode means the trans starts out in second gear in order to at least get to a mechanic). The first thing I would do is have these codes cleared as there may be absolutely nothing wrong with the transmission (especially if you pull the trans dip stick and the fluid does not have a burnt smell. The vehicle should drive normally after that. If the check engine light comes back, have the codes scanned ASAP (before any other unrelated code sets). Chances are it may be the output speed sensor if this happens (easy fix). Hope this helps
P1529 indicates that your TCM asked the ECM to turn on the check engine lamp.
The range switch and the output speed sensors are the items that are
abnormally affecting the operation of the transmission. The diagnostic
logic in your computer can distinguish these issues from one another,
so you'll definitely want to do both. You have no diagnostic code for
the input speed sensor (P0715) listed, so I have made no recommendation
to replace it. In my opinion, it's not a labor-intensive repair, so I
wouldn't recommend replacing it unless you have reason to believe it's
bad.
DTC - P0720 (OUTPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0720 Output shaft speed sensor system
If the output from the output shaft speed sensor is continuously 50%
lower than the vehicle speed for 1 second or more while driving in 3rd
or 4th gear at a speed of 30 km/h or more, it is judged to be an open
circuit or short-circuit in the output shaft speed sensor and
diagnostic trouble code No. P0720 is output. If diagnostic trouble code
No. P0720 is output four times, the transmission is locked into 3rd
gear or 2rid gear as a fail-safe measure.
Probable cause
Malfunction of the output shaft speed sensor
Malfunction of the transfer drive gear or driven gear
Malfunction of connector
Malfunction of the TCM
DTC - P0715 (INPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0715 input shaft speed sensor system
If no output pulse is detected from the input shaft speed sensor for 1
second or more while driving in 3rd or 4th gear at a speed of 30 km/h
(19 mph) or more, it is judged to be an open circuit or short-circuit
in the input shaft speed sensor and diagnostic trouble code No. P0715
is output. If diagnostic trouble code P0715 is output four times, the
transaxle is locked into 3rd gear or 2nd gear as a fail-safe measure.
Probable cause
Malfunction of the input shaft speed sensor
Malfunction of the underdrive clutch retainer
Malfunction of connector
Malfunction of the TCM
YOU HAVE A DEFECTIVE OUTPUT SPEED SENSOR ON TRANSMISSION..ABOUT 40 BUCKS,DEALER PART..SCREWS INTO FRONT OF TRANS..NEAR LEFT INNER FENDER,YOU MIGHT WANT A MECHANIC TO REPLACE..
