SOURCE: Girl changing a camshaft position sensor

The sensor is black and measures approx 3"x3" square with four 8 mm metric bolts holding it in place on the engine. An 8 mm socket with an extension was used to access the bolts and loosen them. Be careful not to drop them down into no mans land. Bright lighting is a must to see what you are doing. 
Once all four bolts were removed, the sensor pulled off the end of the engine with a slight tug. NOTE: It is a good idea to have a cloth or paper towel under this area, as a small amount of engine oil is present between the camshaft and the sensor, and thus leaks out when the sensor is removed. 
Once the sensor is removed, it is easier then to pull off the electrical connector from the sensor, than before it's removal. This is accomplished by first pulling out the red locking tab to the unlocked position, a firm tug should do it, but a small blade screwdriver was required to pry it out of it's locked position. Then squeeze and pull the black part of the connector, to disconnect the wiring harness from the sensor. Voila! One camshaft position sensor removed.
To reinstall the new sensor, I check that the faces that will come in contact with each other, when sensor is reinstalled, are clean and free of grime and excess oil. Put a light coating of engine oil on the new sensor seal (green O ring) using your finger and clean engine oil. This will help the seal when the sensor is bolted back together.
Install the electrical connector by pushing the wiring connector into the sensor and locking it into place by squeezing the red locking tab into it's locked position.
Re-install the sensor onto the engine with the four bolts. Thread the bolts in, then tighten them gently with a little extra force, in an x pattern when tightening the bolts. This distributes the force evenly across the sensor. BE CAREFUL TO NOT USE TOO MUCH FORCE, SO THAT YOU DON'T STRIP THE BOLT THREADS. ALUMINUM IS A SOFT METAL.
After installation of the sensor, just install everything you removed and enjoy a night out with the money you saved.

SOURCE: 2000 dodge grand caravan sport, the check engine

no codes found because your checking the PCM,
your problem is you need codes from the TCM,the computer for the transmission,since you replaced the speed sensor the other two things that affect a speedometer and transmission are the input and output sensors,they both screw in the transmission.

A 2001 jimmy gmc my speedometer dose not work and my transmision will not shift i changed the sensor and it didnt fix the problem i changed the filter didnt help what else could cause this problem

What sensor did you change . VSS - vehicle speed sensor or output speed sensor .
The ideal what to find the problem would be to hook up a factory scan tool to see the VSS is put out a signal to the PCM/ECM , then see if the PCM /ECM is sending info to the instrument cluster ,. And knowing how these this work couldn't hurt either .

The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit exists.

Have the vehicle checked for DTC"S - diagnostic trouble codes . No all code's turn on the check engine light .
DTC P0608
The PCM creates the vehicle speed output signal by pulsing the circuit to ground. The PCM pulses the circuit at the same rate as the vehicle speed signal input. The PCM monitors the voltage on the vehicle speed signal circuit. If the PCM determines the voltage is out of the normal operating range, a DTC sets.

Install a scan tool.
Raise the vehicle's drive wheels. Refer to Lifting and Jacking the Vehicle in General Information.
Start the engine.
Place the transmission into drive for an automatic transmission or third gear for a manual transmission.
With the scan tool, observe the Vehicle Speed Sensor parameter in the PCM data list.
Does the Vehicle Speed Sensor parameter match the speedometer display?

This is something best taken to a qualified repair shop . This could be a wiring issue , or the PCM or the instrument cluster .

My speedometer is fluctuating and the car is sputtering and driving slow

inspect the vehicles speed sensor is working
could be the 0 2 sensor or maf

if the engine light is on
the engine computer will have fault codes
to tell you what sensor is failing

I have a 1996 Honda Accord with 268k miles that sputters at the same timethe speedometer needle fluctuates wildly. But I do have a new Vehicle Speed Sensor. This typically only happens when the engin

I am no Honda expert, but a similar problem happened to my ex sister in-laws Ford Taurus. The speed odometer would jump around and it had trouble shifting (automatic transmission). After driving it I changed out the speed odometer sensor on the transmission and it's been fine ever since. I changed out the sensor because if the cars computer cannot tell how fast the car is traveling then fail safes in place go into effect and the computer will do it's best to keep the cars rpm's down based on the speed indicator and not let it shift or shift properly either. If it's getting false speeds then it will shut down the motor when the speed gets to high and allow it to run as the speeds fall (jumping speed odometer needle). It effects the transmission shift points also. It will either shift erratically or not shift out of say 2nd gear, so that the cars engine can't get damaged based on what signal the speed sensor is sending the computer.

Speedometer stoped working, just replaced the censer & did a trans. service

There is also a cam shaft speed sensor change it and then see. Most other devices require the input of the pulses from this sensor in order to work. Lets face it if the engine (acording to the cam speed sensor) is not running why alow the speedometer to register

I changed the crank shaft sensor but the car still wont start what else could be wrong if that was what the diagnostic said was wrong?

a bad camshaft sensor will cause a no start also. Engine Sputtering, Poor Acceleration, Stalling/Inability to Start. At low speeds a bad camshaft sensor will cause the car's engine to stall. The engine may also experience an inability to turn over, resulting in the car not starting. This may not happen all the time since the car's on-board computer will use the last readouts from the camshaft sensor to operate the pistons and manage fuel flow, which will allow the car to start; but if camshsft sensor. check engine light will be on, if its really bad.

good-day !

My car starts to miss at high speeds. when I hit the gas it sputters. If I turn it off for a while it starts back up. I replaced the knock sensor but it is still doing it.

ideally a fault code scan / diagnostic session is required but from experience i have changed loads of crankshaft sensors and camshaft sensors, these cause a lot of running issues and usually sort them when replaced. hope this helps

P0121 code in a 2000 dodge durango, will he TPS make the ransmission shift spuratically.

Yes..... The TPS can cause this!!! Another sign of a failing TPS is for the rpm's to fluctuate up and down by 100-300 as you drive down the interstate at a steady speed on a level surface.

po121 means that there is a problem with the throttle position sensor ( tps). or in the wiring or connector, most likely its the tps that is bad. first remove connection from tps, heres how to test. use an ohms meter and hook a lead to top or bottom terminal of tps. use other probe on center terminal of tps. move throttle plate slowly, if the needle on meter does not move at a smooth pace, then tps is bad. good-luck!!
