Example reply from a 2021 Ram 1500.

Bits 0 to 15 of the reply, 16 bits. The value is signed.

0x1720 = 5920 → (5920 ÷ 100) = 59.2 kPa

Formula
(val ÷ 100)
Range
-327.68 to 327.67 kPa
Unit
kPa

Confirmed for 2013, 2019, 2021. In testing for 2009 to 2012, 2014 to 2016, 2018, 2020, 2022 to 2024. Not supported for 2017.

  1. The parameter's name and its ID in the OBDb. Confirmed shows when a response from a real car confirms the parameter.
  2. The clutch mark shows a Connectable, a parameter that Pelican surfaces in its interface.
  3. The service and PID/DID asked for, the control module it's sent to, and how often Pelican asks.
  4. The reply's bytes. The parameter's bytes are blue. Bytes for other parameters in the same reply are grayed out. Hover over a byte to see the parameter it represents.
  5. Where the parameter is in the response, and how Pelican converts the raw value into a value.
  6. A real reply, decoded. The raw value comes first, then the reading.
  7. Which model years have tested this parameter.

Absolute throttle position TPSAE J1979Confirmed

Throttle position at idle will usually be more than 0%, and throttle position at wide open throttle will usually be less than 100%.

Pelican can show this parameter as the throttle position.
