 PID Not Workingon: July 18, 2017 (GMT)

GM Transmission Fluid Temperature
PID 221940 (Method 1)
PID 221940 (Method 2)
PID 221949 (Method 3)

Previously Method (2) would work but not now.
Methods 1 and 3 don’t work either.
2008 Chevy Equinox LTZ 3.4L Auto
Transmission: Asin Warner AF 33-5
Torque Application Ver. 1.8.158

Any input would be appreciated.

When you test the pid that use to work
what is the raw hex response reporting?

Hi! This is the response I get:
Result Equation: 52.00
Command: 22190
Response: 6219405B
Variables: A=91 (hex=5B binary -01011011)
Equation Steps: =A-40

I hope you can see the above image. The Transmission fluid temperature should read more 90 degrees F (south Florida)
but it’s reading 51 F.

What are your preferred settings because
51°C equals 123.8°F?

Looks to me that your pid is working but
you are displaying in celsius.

Torque will convert any recognized units (°C)
to the preferred units specified in the settings

Thanks, 51°C would be about right for a cold start up. I had edited to show °F but is guess I didn’t save it or something; I’ll do it again.
Sorry for all the trouble. It was working all the time?

Cap777: I am not receiving any emails about your replies. When does one select to receive them?

Also, which image size for this forum and do I use URLs?
Searched but couldn’t find the info.

Sorry I can’t assist with those questions.
Dropbox stopped supporting public links
so I haven’t been able to post pictures
since and I never used the email notification.

If you changed the units description from °C
to °F in the pid editor expecting a different
result… it will not work that way. The units
label is describing the result for the equation
being used.

Leave the default °C units label as is and instead
