I recently imported a used Toyota Corolla Fielder 2007 model. However, the "check engine" light could come on as you drive. Sometimes, the car just revs on its own; like its engaging a lower gear. I took it for computerized diagnosis and the report indicated that the vehicle speed sensor had a problem and that the output speed sensor circuit had no signal. What could be the best way to handle this? What needs to be replaced; if at all; and how much is that likely to cost?

The first thing is to unplug the sensor and inspect the terminals, especially when the problem is intermittent. Look for the obvious corrosion, but also look for stretched terminals that aren't making good contact. They can usually be tweaked with a small pick to make them fit tighter. There's different designs of speed sensors. Yours has three wires which means there's electronic circuitry inside it. That is often intermittent and is going to cause a lot more failures than the simpler two-wire sensors that just generate a voltage pulse from a spinning internal magnet. Here is the VSS sensor in the diagrams below. #V1. VSS consists of individual wheel speed sensors (WSS) located on inside of each wheel.

On a Corolla XRS 1.8L 170hp 2ZZ 6spd engine, where is the location of the vehicle speed sensor? Can't find schematics.

Hi and thanks for using 2CarPros.

I have attached a picture indicating locations of the wheel speed sensors. On the transmission is a place for a gear driven speedometer gear but it has been replaced with a cover see picture 2.

Let me know if this helps.

Joe

I have the car listed above Ae101, 5A engine. The car is not moving past first gear unless I press down on the gas pedal but then the engine sounds like it's straining. The speedometer stopped working as well and the o/d light is blinking. Mechanics here don't have the part and I'm not sure what to order online. They said it's the transmission speed sensor but there are different types. Input/output etc. Can someone please help me?

Hi Shay,

We can help point you in the best direction, but unfortunately they will need to provide the detail of which one they are looking for. You are correct that there are more than one, so there is no way to tell you which one you need without knowing what they found the problem to be.

There could be a code in the system that points to one or the other but we need that info to confirm.

This issue is usually the output sensor but again, this would be a guess. Let me know if they gave you more detail about the issue or if you can call them and find out the part they need, we can help find it. Thanks

Hello, I'm Danny
I've attached a picture below of what the VSS- vehicle speed sensor looks like on your Corolla. It's mounted in the case of your automatic transmission. This picture and part number is from AutoZone auto parts stores and the part number can be cross referenced from any other auto parts stores near you. Hope this helps and thanks again for using 2CarPros.

The speedometer in my 1993 corolla was working sporadically and recently quit completely. I was told to check the speed sensor. I unplugged it and reoved the bolt, but have been unable to get the sensor out. I have pried on it quite a bit and it is really stuck. Any suggestions?

This is the 4 speed automatic?

Looks like one bolt holds it in: Althouth it does say there is a retaining plate that must be removed after bolt. I have no clear picture of it.

My transmission starts slipping and jumping in and out of gear, while driving sometimes. When this happens the speedometer needle jumps up and down from zero to approximate actual speed of vehicle. I do not know why it does this. Added fluid seemed to help but has not solved problem. Please help!
