PID 2182, here in the theme several times already had information about it
search for a theme

Header: 7E1
Put the answer on the PID 2182 in the PID test mode

How do you create an external PID?
Settings -> Manage extra PIDs/Sensors -> add custom PID -> OBD Header to use -> 7E1

Ok
No luck…need help

The setting Im trying

Setting 1
Mode: 2182 or 21D9
Min/max 0/325
scale factor: 1
Equation: ((((A*256)+B)*(84/1000)-480)/12)
Header: blank or auto (7E1 no data)

Results: temps all over the place

Setting 2
Mode: 2182 or 21D9
Min/max 0/325
scale factor: 1
Equation: ((((A*256)+B)*(7/100)-400)/10)
Header: blank or auto(7E1 no data)

Results: temps all over the place

Setting 2
Mode: 2182
Min/max 0/325
scale factor: 1
Equation: ((((A*256)+D)*(7/100)-400)/10)
Header: blank or auto(7E1 no data)

Results: temps all over

Any thoughts?

Thanks
Rob

Capp777…are you saying to export this info? if yes not sure how to do that…or just list the reading from these setting when the car is first started and then warmed up?

Thanks
Rob

Ok here is what I’m getting

Testing pid
Gauge 1
Results 172.4F
Command: 2182
Header: auto
Response: 7F2112 – changes to “no data” after few seconds
Variables used: A=78(hex=4E, binary=01001110)
Equation:=A*9/5+32

Gauge 2
Results 99.7 F
Command: 21D9
Header: auto
Response: 7F2112
Variables used:
A=78(hex=4E, binary=01001110)
B=0(hex=00, binary=00000000)
Equation:=((((A*256)+B)*(84/1000)-480)/12)

Gauge 3
Results 101.6 F
Command: 2182
Header: 2182
Response: 7F2112
Variables used:
A=79(hex=4E, binary=01001110)
B=0(hex=00, binary=00000000)
Equation:=((((A*256)+B)*(84/1000)-480)/12)

Have a Water coolant gauge that seems to be working and does not jump all over the place. Just to compare one snap shot in time…car running for 20 minutes
Coolant temp = 165.2 F
Gauge 1 temp = 213.8 F
Gauge 2 temp = 141.0 F
Gauge 3 temp = 142.8 F
The garage temp is about 32F right now

Thanks for you help!

You may have more than one module
responding. Your header is likely 7E0 or
7E1.

The fact that you are getting data baffles
me since you are reporting 7F… responses.

Looking for something like 6182… for a
successful response. e.g.,

7E8046182AABB
7E9046182AABB

Please post the response for gauge 3 using
header 7E0. 2182 is not a header. Please be
careful with what you send to your vehicle
to avoid unexpected results.

A*9/5-40 is correct form for °F
A-40 for °C.

not +32 used in gauge 1 listed above.

Updated gauge 3 to 7E0
When I tried 7E1 I got no response

Gauge 3
Results 139.2 F
Command: 2182
Header: 7E0
Response: 7F2112
Variables used:
A=100(hex=64, binary=01100100)
B=0(hex=00, binary=00000000)
Equation:=(((((A*256)+B)*(84/1000))-480)/12)
