Where is the transmission speed sensor located?

Where is the transmission speed sensor located?

Locate the speed sensor. The sensor is found on the bottom of the transmission and can be identified as a small plug that is sticking straight out of the transmission with an electrical connector plugged into it.

Can a speed sensor cause a transmission to act up?

A failing speed sensor will directly impact the transmission operation, leading to delayed shifting and limited gear choices, while numerous other sensors can have similar detrimental effects.

How much does it cost to replace a transmission speed sensor?

To replace the speed sensor, you are going to pay, on average, between $330 and $380. The labor should only cost you between $80 and $100, while parts will run you about $265.

Can you drive with a bad speed sensor?

Can you drive with a bad speed sensor? In general, it is unsafe to drive a vehicle with a broken wheel speed sensor. The car’s computer will not be able to determine the speed that your vehicle is traveling, so it might apply the brakes at a faster rate than necessary or increase the engine power.

What does the transmission output speed sensor do?

A transmission speed sensor calculates the transmission gear ratio when in use. A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car’s powertrain module. The ISS sensor monitors the input shaft’s speed.

What does a speed sensor do on a transmission?

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.

What makes a speed sensor go bad?

As soon as the wheel turns, the cover is knocked off by the tone wheel teeth. It is common for dirt to accumulate on the sensor which inhibits its ability to generate a signal. Although sensors can go bad, the most common problem is faulty wiring or corroded electrical connections.

What is the speed sensor code on my ml 350?

I scanned when I got home and got a P0721 Generic Pending Output Speed Sensor Circuit range/performance code. It’s a 2009 ML 350 w/66k miles and I do have a basic warranty sill active, but it covers the major power-train and engine parts.

What is the error code for a Mercedes 5 speed transmission?

Here is a list of Mercedes 5-speed and 7-speed automatic transmission related error codes. P0720 – Output Speed Sensor Circuit Malfunction. P0715 – Input/Turbine Speed Sensor Circuit Malfunction (Transmission Conductor Plate or 13-pin connector issue)

What kind of transmission problem does a Mercedes have?

P 0716 P0717 P0718 – Input / Turbine Speed Sensor Circuit Malfunction / Range Performance / No Signal / Intermittent All these fault codes point to powertrain malfunction, typically automatic transmission problems. In most cases the problem is one of the following:

Is there a problem with the speed sensor?

This is usually a problem with a speed sensor on the transmission conductor plate. Unfortunately, if this is the problem, the conductor plate replacement is pretty much a dealer-only job because it contains the TCU which requires SCN coding (i.e. encrypting the VIN into it). Did you ever find a solution?
