How to remove the speed sensor from the gearbox?
Before you start removing the speed sensor, place a car jack under the gearbox. STEP 1: remove those 5 screws from the engine mount. It has to be removed STEP 3: use a T45 Torx to remove the speed sensor from the gearbox.
Where is the oil pressure sensor on the motor?
The sensor is buried in between the oil filter and the transmission on the front of the motor. It is very difficult to photograph while in the motor so I have included thisPicture with the front of the car removed to show just where it is.
What does the Red Wire do on the speed sensor?
It holds the engine speed sensor wiring connection (red arrow) along with one for the knock sensor connections (yellow arrow). Remove the connection for the speed sensor and separate them.
Where is the speed sensor located?

Where is the speed sensor in a engine?
One type, the engine speed sensor (or transmission speed sensor) is usually installed on the transmission or transaxle. The other type, wheel speed sensor (or vehicle speed sensor) is installed on the knuckle arm on the four wheels.
What are the symptoms of a faulty speed sensor?
5 Common Bad Speed Sensor SymptomsTransmission problems. ... Erratic speedometer readings. ... Inability to engage cruise control. ... Lack of torque converter clutch application. ... Check Engine Light is triggered. ... An internal electrical fault in the speed sensor. ... Damage on the sensor itself. ... Poor vehicle maintenance.
Where is the speed sensor mk4 Jetta?
Figure 1 The VSS is located at the rear of the transmission, right over the left side axle. After removing the shift cable bracket, pull the heat shield blanket (green arrow) up and off the VSS.
Which sensor indicates engine speed in RPM?
The functional objective for the crankshaft position sensor is to determine the position and/or rotational speed (RPM) of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing.
What happens if I disconnect the speed sensor?
If it's the wheel speed sensors (like for the ABS) the car will run but the ABS system won't be able to do its job. If we're talking about any engine sensors, the engine MIGHT still run, but it will likely run poorly or throw a check engine light.

What is the engine speed sensor?
The speed sensor measures gear or target wheel speed and position. The Engine Control Module can use this information to modify various engine functions such as Air/Fuel Ratio, ignition timing and perform diagnostic tests.
Can you drive with a broken speed sensor?
However, when it comes to wheel speed sensors, a minor-seeming glitch may turn into a major safety risk. That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor.
What does automatic transmission speed sensor do?
The automatic transmission speed sensor is measuring the rotational speed of the transmission. The measured data is used by the engine management to determine the right gears, shifting times and shifting pressures. The sensory unit is either based on the Hall-effect or has a magneto resistive sensor system.
