So I cleared the stored codes on the car and drove it until it malfunctioned then checked the codes.
it gave me a 1574 which I believe is a vehicle speed sensor. My speedo is functioning properly though.
Here is a link to the video I made of the light flashing after I followed the procedure in the ESM . Pretty sure it clearly shows a 1574.
Also I am in Mexico so maybe we do not have the same OBD codes here? I noticed in the ESM is says "EURO-OBD"
Hi Dave ,Yes P1574 and not P1573 as you first said ,good .Yes this is a speed sensor failure , if the speedometer is working you are going to need a scan tool with live data to diagnose this issue as this could be a ECM failure. Possible causes :
This will cause you the problem you are having .
Check the wiring connections first on the sensor and meter ,but this could be a ECM ot TCM issue if the speedometer is working ..
Please get back to me if you need further assistance with this issue But please get back to me with the reply button, and not the poor or bad service, this way i can get back to you or suggest another expert if needed.Kind regards Greg
OK, do you have a location for the sensor? Is it on the trans or the engine? there is a sensor located on the trans in the front right corner not sure if that is the one.
The issue seems to come up more if we have had heavy rains and drive through puddles. If I can find the sensor I can clean the connections and apply some electric grease
That picture above is not a great representation of my engine Trans combo is that supposed to be the Trans that the vss is depicted on?
I took the airbox off yesterday and pulled the sensor. It is in a very exposed location for the elements but the inside of the connector looked ok. I decided to run an experiment and replaced the sensor but left it unplugged.
Car runs and drives like normal, the only difference so far is that when you first start the car the first time it shifts into second it revs a little higher than it normally would but every shift after that is ok.
We have gone as many as 3 days without the car acting up so I am not convinced that it is ok yet. Interesting result though.
No CEL. The OD light blinks 16 times on startup to indicate a problem with the sensor.
What is the PCM? And how does it going into backup mode with set parameters help?
