Speedometer and cruise control not working

Did they give you the specific codes that they found pointing to the wheel speed sensors? I suspect you have a wiring or module issue at this point but let me know what the codes are and we can get the detail to figure out next steps.

Just from this info, this sounds like a speed sensor issue but it may not be the wheel speed sensors. It could be a vehicle speed sensor. Getting the codes will help figure this out. Thanks

P0460 - Fuel Level sensor circuit malfunction
P0500 - Vehicle Speed Sensor
P1574 - ASCD Vehicle speed sensor

This is as I suspected that this is the vehicle speed sensor and not the wheel speed sensors. Basically these codes (except the fuel level sensor which is not related) are telling you that the input and output speed sensors are not the same.

Here is all the testing that needs to be done for each one of these. Let us know if you have questions.

I attached the info for these sensors and yes, they look similar but these are found in the side of the transmission. If you replaced both of these and you still have these codes then the sensors are most likely not the issue. Rather a wiring issue or control module issue. We need to run through the testing to confirm.

Unfortunately this is not definitive. We actually need to look at what the computer of the car is seeing from these sensors and to do that you need a scan tool capable of seeing the RPM signals from each sensor. These two signals need to be what the ECM is expecting to see from each one so that it can confirm the engine and transmission are operating the way it is supposed to.

Without this scan tool, we would be guessing because just because there is voltage does not mean it is sending the proper signal to the ECM.

Does that make sense?

Okay. This is good info. I suspect the issue is the Unified Meter and AC amplifier. Take a look at this info. The sensors send the signal to the ECM. The ECM then sends the signal to the unified meter and it sends the command to the cluster. If the cluster is new and the ECM is getting the signal of the engine speed then the issue must be this component.

I included the process on how to check it and make sure the circuits are okay and if they are then the component is confirmed as the issue.

Let me know if you have questions and we can go from there. Thanks

If the entire circuit board was failed then that could be. However, take a look at the screen shots of the testing I attached earlier. This lists the Unified meter as a possible cause so if we run through the testing laid on in those documents, you can confirm this but I am just trying to piece that together based on what you told me.

Let me know if you have questions but if you have doubts then we need to do the testing which is what I would do because I don't like replacing parts if they are not confirmed.
