Speed sensor A

Does anyone know where the hell speed sensor A is!? Been chasing this for months and nobody seems to have an answer....I know there are two on the trans and the 4 wheel sensors. I just cannot confirm which it is!

There is no Speed Sensor A... Are you chasing a P0500-Vehicle Speed Sensor "A" problem?

This is one of those codes that is kind of not very clear with it's description. Vehicle speed on 4th Gen 4Runners is calculated by the ABS Module by combining the 4 ABS Wheel Speed Sensor inputs and averaging them together. An intermittent P0500 can be caused by one or more of the ABS Wheel Speed sensors not reading accurately and/or dropping out intermittently. It can also be caused by an issue with the ABS Module Communicating with the ECM and/or the Combination Meter (the ABS module reports vehicle speed data to the ECM and Combination meter separately, the ECM uses it for transmission shift logic, engine management, and cruise control; the combination meter uses it for cruise control and reporting vehicle speed).

The easiest way to find out which sensor is causing issues is to get a scantool that can communicate with the Toyota ABS system and pull the live data to see what the wheel speed sensors are reading and to test drive the vehicle and see which one is dropping out/reading incorrectly.

You could also try and look for any damaged/stretched looking abs wires as well as removing the wheel speed sensors and making sure they don't have crap stuck to the tips.

But before all that, could you give a brief history on the issue and when the DTC started occuring?

Thanks for the info! Been a while since I have been on here! No idea when it kinda started or why. Still hadn't fixed it,divorce stuff. Anyhow,I have some spare sensors I can just start swapping them out.
