Example reply from a 2021 Ram 2500.

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

0x18D8 = 6360 → (6360 ÷ 100) = 63.6 kPa

Confirmed for 2021. In testing for 2010 to 2020, 2022 to 2026.

  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.
