    The speed sensor you replaced is not going to restore driveabilty problems. the only sensor subject to physical wear is the TPS (THROTTLLE POSITION SENSOR) And possibly the 02 sensor (2005) due to age. Do The cheapest fixes first to avoid buying parts you don't need. Following the Maint. schedule in the owners manual goes a long way toward continued performance.

What filter did you change? How about the fuel filter. Sounds like fuel starvation. What prompted the speed sensor change. They rarely go bad. I recommend an ODBII scan, with a print out of the stored fault history. Let the OBDII scan be your guide to any parts replacement, to avoid buying parts you don't need. All filter replacement should be done every 30,000 miles.

SOURCE: check engine light code P0720...failed output

The output shaft speed sensor lets the computer know how fast you are going down the road to help it pick gear change points..
Yes, you can buy one and replace it.
First check the wires and plug going to it.
Your manual will probably describe its location better than me, but it will be toward the rear of the gearbox and usually has a small gear on the end that meshes with a mating gear on the output shaft as you put it in.

SOURCE: I have 05 ford tarus

has there been a collision recently? not sure why transmission problem would make engine not run. what do you mean it sounds like air is coming from somewhere? sounds like there is a problem in wiring harness. Ford has had a lot of problems with water getting into harnesses. not sure if this is you but the problem sounds that way unless you have been in a recent collision that could have damaged wiring. please reply and i will be watching my emails

05 expedition won't pull in drive have to keep giving gas and then it takes off even when u stop changed filter


Any warning lights lit on the instrument cluster ? Check engine light , yellow wrench symbol light . Redued engine power message ? Your vehicle has electronic throttle control ! The gas pedal is hooked electrically to the PCM - engine computer which controls a DC electric motor on the engine ,controlling the throttle plate . Has position sensors in the gas pedal and in the throttle body . They wear an cause these type problems . Suggest you take it to a qualified repair shop .

Ok one major question! Will changing the tcc solenoid in my 01 cougar fix the o/d flashing and make the car go forward when I try to drive it?


No. replacing the TCC or the OSS, will not make the transmission work. You can unplug these transmissions and they will still work, less OD. Sounds like you may have stripped the torque converter oil pump gear. Common in these older Mercury/Fords.

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.

I have a nissan altima 05 3.5L engine service light just came on and my scanner read these codes P0722 and p0717 p0462 and p0500 are these things i can fix on my own?


CODE PO462 FUEL TANK LEVEL SENSOR VOLTAGE LOW. CODE PO717 TURBINE SHAFT SPEED SPEED SENSOR NO SIGNAL. CODE PO722 OUTPUT SHAFT SPEED SENSOR NO SIGNAL. CODE PO500 VECHICLE SPEED SENSOR CIRCUIT MALFUNCTION. SOUND LIKE YOU HAVE TCM ECM PROBLEMS GETTING TOO MANY CODES. COULD HAVE LOOSE GROUND WIRE TO THE TCM AND ECM.

1997 expedition PO503 code, 4WD, 4.6 motor, changed coil pack and spark plug


The code is specific to the engine speed sensor located on the side of the transmission near the output shaft. This device measures the output shaft rotation speed and allows the Electronic Control Unit (ECU - power control module) to program gear shifts as well as when to engage anti lock braking or traction control (by monitoring the output shaft speed sensor and comparing this with inputs from the wheel hub sensors). Locate the speed sensor connection and make sure the all the electrical contacts are free of dirt and corrosion. Remove the speed sensor and make sure that it looks physically OK and is clean, especially its tip. Check that all the wires are intact and that there is electrical continuity back to the ECU. The error code is consistent with an intermittent connection but if you suspect that the sensor itself is at fault it is not a very expensive item to replace.

The Mazda Dealer installed the speed sensor, but the car still doesn't work in drive. I have to start out in second in till around 20 m.p.h. The problem just started two weeks ago. The car has only been in...


0452-Fuel Tank Pressure Sensor according to my 2004 Ford Emmisions Manual. What is the problem? Don't know. What iam reading doesn't say to replace the sensor. What year and make is this vehicle. Also, if it is a Ford product ,you may be looking at the need for the Trans Solenoid Pack. The Speed Sensor is an output shaft sensor. You may have two others. The turbine,for converter and an intermediate one. Anyway the sensor the dealer did wouldn't effect it going into drive,as the output shaft is not turning,when the driveshaft is not.

Check engine light with following codes p 1529 p0720 p0715


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

Is needed replace.

1999 ford expedition - transmission slip?


the flashing O/D light usually means you have a bad speed sensor that sends speed info to the engine & trans computer.

Vehicle Speed Sensor The vehicle speed sensor (VSS) (Figure 42) is a variable reluctance or Hall-effect sensor that generates a waveform with a frequency that is proportional to the speed of the vehicle. If the vehicle is moving at a relatively low velocity, the sensor produces a signal with a low frequency. As the vehicle velocity increases, the sensor generates a signal with a higher frequency. The PCM uses the frequency signal generated by the VSS (and other inputs) to control such parameters as fuel injection, ignition control, transmission/transaxle shift scheduling and torque converter clutch scheduling.

-------------------------------------------
Some trans use an OSS, Output Shaft Sensor instead of a VSS. Depends on which trans you have, 4R100 or 4R70W

Transmission Control Switch (TCS) and Transmission Control Indicator Lamp (TCIL)
The transmission control switch (TCS) is a momentary contact switch. When the switch is pressed, a signal is sent to the powertrain control module (PCM) to allow automatic shifts from first through fourth gears or first through third gears only. The PCM energizes the transmission control indicator lamp (TCIL) when the switch is off.

The TCIL indicates overdrive cancel mode activated (lamp on) and electronic pressure control (EPC) circuit shorted (lamp flashing) or monitored sensor failure.

Output Shaft Speed (OSS) Sensor
The output shaft speed (OSS) sensor is a magnetic pickup, located at the output shaft ring gear, that sends a signal to the powertrain control module (PCM) to indicate transmission output shaft speed. The OSS is used for torque converter clutch control, shift scheduling and to determine electronic pressure control.
