Looking for a speed sensor as mine is faulty. Finding it hard to get a second hand one. How much would a new one cost and where can i get one from?

automatic , probably a faulty vehicle speed sensor or manual a faulty sensor in the transmission
check wiring and connections for corrosion , oil , broken wires

at a rough guess the second hand unit is faulty

There are vehicle speed sensors on all four wheels and usually another on the transmission. Depends on why you are replacing and what system you are having trouble with. The ABS uses the four wheels to gauge speed for stopping and traction control purposes. The sensor on the transmission (output speed sensor) is the one that feeds data to the computer for the speedometer. Take off your tires and the speed sensors are easy to find behind the brake rotors. The trans mounted sensor will be easiest to find by having the new part in hand and finding the corresponding sensor to match.

Sorry to hear about your problem. There are multiple issues here, which cannot be solved simply. If you or someone you know does not have automotive mechanical knowledge, you need to get your vehicle into a repair shop. If you are looking for a low cost answer, you can check with a local auto part store and see if they can "pull codes" (since you mentioned a "check engine light". This, at least, would give you some idea of what is going on. You can also take it to an ASE certified, and trusted repair facility and have them run a diagnostic. If it won't shift, it's likely something to do with the transmission. If the speedometer doesn't work, either the cabling, sensor is damaged, or you have a blown fuse. You need someone qualified to actually examine your vehicle. Good luck!

CODE PO720 - OUTPUT SPEED SENSOR MALFUNCTION / CODE PO732 - INCORRECT GEAR RATIO SECOND GEAR / CODE PO781 - FIRST TO SECOND SHIFT MALFUNCTION / CODE POP1247 - TURBOCHARGER BOOST PRESSURE LOW CONDITION. COULD NOT FIND CODE PO1316. LOOK ALL PROBLEMS COULD BECAUSED BY CODE PO720 FAULTY OUTPUT SPEED SENSOR IT CONTROLS TRANSMISSION SHIFTS.

SOUND LIKE FAULTY VECHICLE SPEED SENSOR.ALSO CHECK SPEED SENSOR ELECTRICAL WIRES AND CONNECTOR MAKE SURE ITS IN PLACE NOT LOOSE OR DAMAGED.

The part number I have is W0133-1750884, this is from partstrain.com.

Here is the link if you can use it.

Good luck.

probably the shuttle valve in the ABS unit is defective, solution renew shuttle valve, dont let dealership sell you a new ABS unit very expensive

I had a 2001 and the transmission was not shifting correctly that was diagnosed as a speed sensor issue.

There is a speed sensor on the transmission, near the rear.

And there is a speed sensor on one of the front wheel hubs...

Tell me what the problem is?

I hace a 19196 sable-the problem is the transaxle speed sensor-this part sends all speed info to the computer ..-First symptom(speedometer stops working and then transmission shifts erratacially and power steering becomes hard and engine light comes on..The computer on this all eletronic car cannot send proper signals to the speedo-trans-power steering and other functions without knowing how fast or slow the car is going..Have the SPEED SENSOR mounted on top of the tranaxle replaced and all will be well.Part is not to expensive.labor can vary depending whether you have 3.0OHV or DOHC engine-some cars have to have exhaust dropped to get at it-Good Luck All
