2005 wire schematic

Hello I’m Looking for wire schematic for 2005 Tacoma v6 automatic abs system. Having speedometer issues . If anyone could help me out with that be greatly appreciated thanks !!

 

We can help you with that.
But I have to ask, do you have a CEL on?
Is the code P0500?

 

Here is a diagram.
But I think you'll need more than the diagram to fix your issue.

Let us know if you need more help.

 

Only codes are for both front wheel front abs sensors but wiring to sensor checked good and just curious procedure to test sensors. Just find it strange for both front wheel sensors to be both coding. Had a code for rear right abs found broken wire at 4 pin plug in at rear . Fix that no more code for that wheel just the front .

 

Ok. Scroll down to the Speed Sensor Operation section in the link below.
Be sure to click the "spoiler" button. Grey button.
You'll find all you need to know.

I looked and There is no speed sensor at my transmission / transfer case output shaft . Its reads from all sensors from all 4 wheels ? So this link seems to be trouble shooting from a 2wd system or am I missing something here ?

 

No. The automatic operates off the rear wheel speed sensors.
Doesn't matter if it's 2WD of 4WD.

 

To be clear what are we chasing here, a P0500 or C02xx codes?

 

He said it wasn't a P0500.
Just codes for both front sensors.

But the rear was damaged at one point.
And supposedly fixed......

 

Well we need to know the codes to really know what we're after here, speedometer problem may or may not be related.

I'm assuming this is the standard vacuum brake booster and not the hydraulic one?

 

The codes I had initially were c0210 right rear speed sensor . Wire to the sensor was broken & repaired and code was able to be cleared as prior before fix it could not be so assuming that code is fixed now and that wheel sensor is now reading. ( my code reader is basic and can’t show individual wheel speeds etc.. just codes)
So right now I have 2 codes that are c0205 &c0200 . But now since the it’s just the rear wheels that work with speedometer I’m now curious.
So back to schematic . My rear speed sensors enter the skid control ecu. And from where does it keep going to finally convert my wheel sensors to the speedometer? Thanks for all your help guys and your quick responses by the way much appreciated!

 

I'd first check power at the sensors


Then

 

After looking under truck I’ve notice I have these same 2 sensors that appear to look like speed sensors does anyone know what they are . Input and output speed ? And how they operate in the system

 

You’d be right in saying they are speed sensors.
But they monitor the speed of internal components of the transmission.
They’d be better described as “rpm” sensors.

They have nothing to do with MPH.
