How does the TSS sensor work on a turbine shaft?

The ISS sensor can be a permanent magnet (PM) generator or a Hall-Effect switch (Creates an on–off square wave signal that is used directly by the PCM/TCM for speed detection). The TSS/ISS sensor mounts into the transmission case and maintains a slight air gap between the sensor and the forward clutch housing.

What does the output speed sensor ( OSS ) do?

The output speed sensor (OSS) is also called the vehicle speed (VS) sensor and is used by the PCM for speedometer and cruise control operation as well as for transmission/transaxle operation and shift-related fault detection and if defective will set DTC related to cruise operation.

What happens when a transmission speed sensor goes bad?

A failed transmission speed sensor could cause the engine light to come on. Some transmission speed sensors are driven by a gear making them like a governor, however, most speed sensors are magnets that change signal when the output shaft is turning.

Where is the speed sensor on a transaxle?

For transaxles, the speed sensor is located on the long side of the output shaft. This would be the end of the transaxle that faces the front of the engine. Step 1: Install the new sensor. Make sure that new o-ring is on the new transmission speed sensor. Install the new sensor into the output shaft housing.

Which is the output shaft speed ( OSS ) sensor?

The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’ input shaft. The other sensor is the output shaft speed (OSS) sensor.

What happens when a transmission speed sensor goes out of alignment?

If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.

When does a throttle position sensor need to be replaced?

Throttle Position Sensors. The sensor’s out put can be checked with a voltmeter, or observed on a scan tool. If there are any drops in the output as the throttle opens, the sensor is bad and needs to be replaced. On some older vehicles, the idle voltage setting of the sensor must be adjusted to a specified voltage.

When to replace the oxygen sensor in your car?

This, in turn, can cause emissions, performance and drivability problems. Except for some early 1980s vintage oxygen sensors, most sensors have no factory recommended replacement intervals. They work until they don’t. In other words, they are designed to last the life of the vehicle or until they fail.

What is the name of the transmission speed sensor?

There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.

If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.

Is the TSS and OSS 6F50 transmission failure?

This failure to the TSS and OSS does apply to the FWD and AWD models with the 6F50 six speed transmission. This video attempts to explain what it is and what to expect as the symptoms develop. Technical repair information can be obtained through MACTFORDEDGE on Facebook. https://www.facebook.com/groups/MACTF…

Where is the turbine speed sensor location on a 1998 Ford?

where is the turbine speed… The turbine shaft speed (TSS) sensor is a magnetic pickup that sends the powertrain control module (PCM) torque converter turbine speed information. The TSS sensor is mounted internally on the center support.

Can a TSS signal increase with engine RPM?

Compare engine RPM, usually the crankshaft position sensor (CKP) with TSS, and you should be able to see the signal to increase and decrease with engine rpm. If you see any problems with the signal, such as dropouts or changes in voltage, recheck the wiring harness before condemning the sensor.

What to do if turbine shaft speed sensor is not working?

The TCM also monitors the turbine speed sensor itself for problems, which it would expect to find in a certain range and change speeds at a certain rate. If the TCM detects problems with the TSS or TSS circuit, it will set a diagnostic trouble code (DTC) in memory and command the ECM to illuminate the check engine light.

Is there a problem with the transmission on my Taurus?

Problem seems to be worse the warmer the car is. By the way- my car has 245K highway miles and it is a 1998 Taurus LX. I was warned about bad transmissions in Ford Taurus, but I bought this car anyway, as the transmission worked perfectly during test drive.
