Output shaft speed sensor 2013 Ford Mustang what will happen if I disconnected car is not running right now

Output shaft speed sensor is bad what will happen if I disconnected will car still run

My car has 89000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Disconnecting the sensor will cause the vehicle computer to see an open circuit to the sensor and turn on the Check Engine Light. The computer may go into a failure mode and cause many different drive problems depending on the computer strategy in its programming. You will most likely have shifting hard on up shifts and downshifts of the transmission. The overdrive may be disabled along with cruise control and other speed related components. Before disconnecting the sensor the code you are getting now should be diagnosed. This way you will know if it is a sensor problem or an internal transmission problem.

Improper Or Harsh Shifting

When there`s no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won`t control them correctly. This will make the transmission not work properly.

A failing transmission position sensor may no longer send the right signals to the Powertrain Control Module, or PCM. Without signals from the position sensor, the PCM will no longer know when to shift the transmission`s gears out of park into a moving gear. Transmission shifts into the wrong gear.
This sensor controls ignition timing of the engine and when it fails the computer does not know when to ignite the cylinder causing the engine to stall and not start correctly. I would recommend having a technician from YourMechanic come out and replace the sensor.
It`s also common that a problem with these sensors can impact the shift timing, extending the interval between transmission shifts. An automatic transmission is hydraulically controlled and designed to operate smooth.
In fact, most sensors are responsible for actually making the changes to critical systems such as ignition and fuel systems. Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can`t adjust these symptoms on the fly can cause the engine to not start.
Transmission speed sensors cannot be repaired, only replaced. While transmission speed sensor failure is not uncommon, many other problems can present similar systems such as ABS sensor failures. A full professional inspection will be needed to determine the actual cause of the problem.
Typically, two sensors communicate the transmission data to the vehicle`s powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission`s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.

Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on.
The speed sensor detects a gear or target wheel in the transmission and generates an electric digital signal proportional to the speed of rotation. The transmission controls use this information to modify various transmission functions such as shift points and perform diagnostic tests.
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor`s wire coupling. Using the multimeter`s voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.

Output shaft speed sensor 2013 Ford Mustang what will happen if I disconnected car is not running right now
ANSWER : Disconnecting the sensor will cause the vehicle computer to see an open circuit to the sensor and turn on the Check Engine Light. The computer may go into a failure mode and cause many different drive problems depending on the computer strategy in its programming. You will most likely have shifting hard on up shifts and downshifts of the transmission. The overdrive may be disabled along with cruise control and other speed related components.

Front right suspension area making a clicking noise that speeds up as car goes faster. My car is a 2013 Infiniti G37x.
ANSWER : Hi there. The clicking noise in the right front may be, any number of possibilities. A loose wheel, a wheel bearing going bad, possible brake pad movement, resulting from poor fitting pads, a worn axle shaft cv joint. There are more possibilities. To avoid any unnecessary repairs, I recommend having your vehicle’s right front clicking noise be diagnosed and repaired by a certified technician, such as one from YourMechanic.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

Intermittent issue where after a stop car is stuck in first, speedometer at zero. Had output speed sensor changed, no change.
ANSWER : Hello there, a few possible faults could cause the vehicle to become stuck in first. The most common would be low fluid level, shift solenoid, transmission range sensor, or a transmission mechanical fault. I’d suggest getting this looked at by a qualified technician, such as one from YourMechanic, who will be able to diagnose your shifting issue and perform any repairs required.

My Audi A4 has a bad transmission range sensor and when accelerating the car shakes, I don’t know if it’s the sensor?
ANSWER : A faulty transmission range selector switch/sensor could have some negative effects on vehicle performance and consequently the switch should be replaced prior to a diagnostic for the acceleration problem you are describing. After the sensor/switch is replaced, if the acceleration problem remains, that problem would be identified and resolved during a slow acceleration diagnostic. To obtain replacement of the range selector component, please use YourMechanic’s transmission range selector service page and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car is running fine (somewhat) but have P0345 code (cam shaft position sensor).
ANSWER : The most common cause of this code is going to be the timing chain and timing gear phasers along with cam solenoids can all cause the problem of cam misalignment. The problem can cause low power, rattles and check engine codes for cam sensors detecting misaligned camshafts. The most common fix is replacing camshaft phasers, timing chains and guides and cam solenoids.

Car intermittently won’t start
ANSWER : Hi there. An intermittent no start condition, can be difficult to diagnose. Replacing the fuel filter would not hurt anything, especially if it hasn’t been replaced in the last 30,000 miles. Diagnostic procedures should be performed, at the time of no start, to confirm whether there is a loss of fuel, of spark or both.

Assuming the Check Engine Light is not coming on, leads me to believe the ECM (engine control module)/computer is not recognizing the fault. There are many possibilities for a no start condition: a faulty ignition switch, fuel pump relay, fuel pump, ignition coil, ignition module, crankshaft position sensor, camshaft position sensor.

Replacing components without diagnoses can be expensive and time consuming without resolution. I recommend having your vehicle’s intermittent no start diagnosed and repaired by a certified technician, such as one from YourMechanic, so that this can be repaired correctly.

Power steering loss, no belts are turning but the car is running fine. I also have a soft pedal. Whats wrong with my car?
ANSWER : I have only seen this situation once in my 30+ years and it turned out to be a broken crankshaft pulley. Belts are driven by the engine. The crankshaft pulley spins the belts, which in turn spin the air conditioner compressor, power steering and water pumps, and the alternator. The vehicle should be towed to your local repair shop and not driven. Without the water pump spinning to circulate the coolant, the engine will quickly overheat and result in more extensive damage.
