OBD reader will not read the oil temp.

I bought myself a VeePeak obd reader a couple weeks ago and I cannot get it to read the oil temp. to read. I use the app obdfusion to read it. Can anyone help me out here?

 

Does it show the PID codes for that gauge or was it a blank guage that you added to the app?

 

This may or may not help, but ... al of these readers have "PIDs" (basically data/info addresses) where the ECU stores sensor info. Sometimes you need to use a custom PID in the app. There's a thread on it here to share PIDs and such, if it helps: https://www.tundras.com/threads/obd-thread-pids-apps-dashboards.60459/

 

I see this post says there is no oil temp sensor (for crankcase). No oil temp sensor would mean the ECU isn't capturing that data, thus can't display it.

There's one for trans temp though, the PID has been shared in 1GT forum a few times.

 

@Tundra234 It is has the PID codes from the app. The app had the "engine oil temperature" PID already but it doesn't read through the OBD. When I got it the transmission temps would not read but I found someone had made a different code for the Tundras so I just entered the different codes into the existing PID and it reads trans temps now. I was thinking maybe someone smarter than me had made a oil temperature code too but if @shifty` is correct there is not even a crankcase thermostat.

 

You could add a temp sensor if you wanted. URD makes an Oil filter "sandwich" block to add sensors.

And they have oil temp gauges, but I have no clue what kind of sensor you'd need other than a k-type or J-type thermocouple that screws into the sandwich block.

My 2019 has no oil temp sensor either. The PIDs on my OBD MX+ allow you to display an oil temp but its just based off of the ATF pan temp and basically just display that within a couple degrees.
