No you don't have to move any of that you need a "crow foot" type oxygen sensor it looks like a short brake line wrench that you can put a 3/8 ratchet on it with an extension. This will help you to get this sensor out. Good Luck

SOURCE: locassion of output speed sensor on 2003 Town and Country

The input and output speed sensors look identical on the connector side. The one over the solenoid pack is the input, the one closer to the left frame rail or left front wheel is the output sensor. I hope this helps.

SOURCE: Code: P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1

is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.

if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

Circuit/System Description
The input speed sensor (ISS) is a hall-effect type sensor. The sensor faces the 1-2-3-4 and 3-5-R clutch housing machined teeth surface. The sensor receives 8.3-9.3 volts on the input/output speed sensor (ISS/OSS) supply voltage circuit from the transmission control module (TCM). As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the machined surface of the 1-2-3-4 and 3-5-R clutch housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.

Circuit/System Verification
Engine idling, observe the scan tool Transmission ISS parameter while varying the engine speed. The Transmission ISS parameter should change with the engine speed and not drop out.
Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Ignition OFF, remove the control valve body cover. Refer to Control Valve Body Cover Replacement.
Connect the TCM harness connector.
Disconnect the input speed sensor (ISS) from the control solenoid (w/body and TCM) valve assembly.
Connect the J 38522 between the supply voltage terminal B and ISS signal terminal A at the control solenoid (w/body and TCM) valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test for further instructions.
Set the J 38522 signal to 8 volts, the frequency to 120 and the percent duty cycle to 50.
Ignition ON, observe the scan tool Transmission ISS parameter. The scan tool Transmission ISS parameter should be between 100-400 RPM.
? If not within the specified range, replace the control solenoid (w/body and TCM) valve assembly.
If all circuits test normal, test or replace the input speed sensor.

Control Valve Body Cover Replacement

Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement.
Remove the oil cooler inlet hose (1) from the retainer on the control valve body cover.
Remove the oil cooler outlet hose retainer nut (5) from the control valve body cover.
Remove the oil cooler outlet hose (4) from the retainer on the control valve body cover.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
Remove the left engine splash shield. Refer to Engine Splash Shield Replacement.
Drain the transmission. Refer to Transmission Fluid Replacement.

Po715


I do not believe so . Code p0715 if that relates to your question refers to the turbine shaft speed(TSS) sensor-circuit malfunction===causes wiring--TSS sensor--ECM/TCM
The drive speed sensor is the sensor that works the speedo and sends impulses to the transmission control module to change gears in relation to the turbine speed sensor
This is how the TCM knows when to change ratios in the transmission because of the differences in recorded speeds of the engine torque convertor and the drive shaft

Speed sensor


The sensor should be in the side of the transmission.
The speedo would stop working, or you would have shifting troubles with the transmission. And you would have a check engine light on with a trouble code for the sensor.

My 97 volvo was in an accident before i bought it and my speedometer works but my odometer doesn't what or where should i begin looking to fix it


The speedometer works from the speed sensor (top of transmission casing, near engine. The Odometer must run from a cable from the transmission housing toward the firewall and the instrument cluster. The cable is either disconnected, broken or worn. You need the disconnect it and turn it with a drill to see if it works.
Source : I had a mazda where the cable became all rounded up where it connects into the transmission, I had to change the odometer cable. I did however change the speed sensor on my 94 850.

I have a 2000 Mazda 626 LX 2.5 L automatic transmission with the code p0715. Any help?


no
a vehicle speed sensor ( VSS) reports on the vehicle speed to the ECM, speedo and TCM
the turbine speed sensor reports on the input shaft speed so that the TCM knows when to change ratios against the VSS reports
the sensor is readily available from dealer spares , transmission shops , e-bay or the wreckers / junk yards
talk with an accredited transmission specialist shop

Location of transmission sencor??


The input an output speed sensors are located in the front of the transmission (the side facing the radiator). The input speed sensor is the one right below the rubber transmission cooler lines. the out put speed sensor looks exactly the same and is located more toward the drivers side of the transmission.

If you looking for a different sensor let me know. Thank you for using FixYa.com!

Where do u locae a speed sensor on a 2006 chrysler 300?


A wheel speed sensor?

They are located at each individual wheel.

An output or input speed sensor?

They are located on the drivers side of the transmission. They are yellowish white in color and look identical to each other. You will need a 1 inch socket to remove and replace them.

The input speed sensor is towards the front of the transmission and the output speed sensor is located toward the rear of the transmission.
