Replacing output speed sensor on 2002 sonata

I need step by step instructions on replacing the output speed sensor and input speed sensor on my 2002 sonata. thank you. I also think there is a problem with my 02 output speed sensor - or at least that is what came up when they hooked the computer to it - you see, mine was not shifting gears correctly - I stopped yesterday to put gas in it - when I left gas station, the RPM's went way up and then it jerked into gear, then the engine light came on - this also happened to my son two days ago but my husband could find nothing wrong - we went and got the part but can't figure out how to get to it - the Hyundai place said it was easy, just losen a bolt and replace it - you can't get to it that easy - now though we actually think it may not be the sensor but the wires that attach it - looked on Autozone for diagram and they don't have one - any other online places I could find it?

    code that came up was BBOutput speed sensor error
    Probable cause
    BB1 - open pr short circuit condition
    BB2 - poor electrical connection
    BB3 - Failed output speed sensor

    we bought the output speed sensor but need to know how to get it out - the part store showed it me, but how do you get it out - do you have to take the whole motor apart?

    we found it and guess what - that was May and just this last week happened again - this time code read 0715 - input speed sensor - car is junk and I will never buy foreign again. O2 sensor, output speed sensor, input speed sensor, all four door windows need something, and cv axles and my husband named another part too but can't remember what it was - money pit.

    these are inside the transmission, when u get a code from them it means the trans is slipping, it seldom ever means the sensors have a problem, think about it, what are the chances that both would fail?

Agreed, your sensore is telling you somethings wrong with the trany. replace the sensor last. from what you describe you have a worn out fritchion cltuch plate. check your trany fluid for shiny particles in the oil or paper like material. this is telling you your tranys clutch plates are going and going fast.

and to find the sensor it will be on the out put shaft part of the trany. it will be on the out side with 2 wires going to it. (this is a hall effect type sensor) it will have a retainer holeing it into place.(possibly an 8 mm bolt) sohuld be the same front and rear wheel drive. front wheel drive is harder to find but look at the axle shalfts and where they conect to the trany. this is the ddifferential. it should be close to this location if not look closer to the main body of the trany. along the back side closest to the fire wall.

P0715 = Input Shaft Speed Sensor Malfunction
P0765 = P0765 Overdrive solenoid valve problem
The Input shaft speed sensor is located on top of the trans (center) under the shifter cable (the shifter cable is connected to the transaxel range switch). The Overdrive Solenoid valve is located INSIDE the trans (oil pan must be removed to access it).Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

This would be on of your downstream heated Oxygen sensors. I believe you have 3 - 4 O2 sensors on this vehicle. Would recommend taking to a repair shop for the repairs, some of these O2 sensors can be tricky to get to. Hope this helps

Look for a vacuum leak somewhere. This is the most common problem for a high idle.

Speed sensor


Speedometer sensor measures axle(driveshaft) speed for your speedometer gauge.
Input speed sensor measures the speed of the input shaft of the transmission.
The output speed sensor measures the output shaft, the ECM compares these two signals to determine the amount of clutch slippage and adjusts parameters accordingly for optimal operation.

AUTOMATIC TRANSAXLE DIAGNOSTIC TROUBLE CODES P0715, P0716, P0717, P0720, P0721 & P0722

An improperly functioning input speed sensor or output speed sensor may result in the following conditions:
^ "Check Engine" light on
^ Harsh P-R or P-D engagement shock
^ Transaxle in 3rd gear fail-safe
^ Diagnostic trouble codes 1. Using a GDS, check for DTCs in both the "Engine" and "Automatic Transaxle" menus. Record the DTC and description.
2. From the GDS, select:
^ Vehicle
^ "Auto Transaxle" menu
^ "Current Data"
^ "Input speed sensor" and "output speed sensor". Drive the vehicle and monitor the input and output speed sensors. If the sensors show:
^ Continuous output, the wiring currently has no open/shorts. Go to Step 6.
^ No output, go to Step 3
3. Check the wiring harness visually for an open circuit or short circuit to ground. Check for a pinched harness at the PCM/TCM attachment bolts.
4. Disconnect the connectors at the input and output speed sensor and PCM/TCM. Check for bent pins or pins not fully inserted into the connector.
5. If a harness open/short is found, repair or replace the ECM control harness between the PCM/TCM and transaxle and go to Step 8. If not, go to Step 6.

CANT FIND WHERE THE SPEED SENSOR IS NO MY 1995 OLDSMOBILE AURORA


hi , their is two different speed sensors on your vehicle one is the input speed sensor which is inside the transmission and the transmission will have to be removed to replace it the other one s the output speed sensor is located directly above the passenger side trans-axle shaft. your input sensor is the sensor which tells the transmission when to shift and the output speed sensor tells the speedometer what it should display and both those parts are fairly cheap they are around 15-25 dollars but just remember if your input speed sensor is bad it is gonna cost you a minimum of 1000 dollars to have a mechanic fix as the transmission needs to be removed hope this is what you needed

Where are the input and output speed sensor relays located in the transmission?


There are no relays in a speed sensor circuit. If you are talking about the relay itself, the output speed sensor is going to be in the extension housing of the transmission, and it probably doesn't have an input speed sensor, since it uses the crankshaft speed sensor as an input speed sensor.
