Appendix A: Global OBD II PID List &
Definitions
All parameter identification data (PID) listed was verified on actual vehicles to guarantee
accuracy. Definitions used to describe all PIDs were obtained from reliable sources and
are accurate at time of printing. It is possible that some newer vehicles may contain different
data different from that listed. In these cases, refer to an applicable vehicle service manual.
Data Parameter List Format
The PID list is organized in alphabetical order — the same way the scan tool does. For each
PID, the type of reading are provided. Remember to always refer to a vehicle service manual
for detailed diagnostic procedures for troubleshooting incorrect PID readings.
Types of Data Parameters
INPUT: These data parameters are obtained from sensor outputs. Sensor outputs
are inputs to vehicle’s computer module(s). For example, if an Oxygen Sen-
sor was generating a 400mV signal, then the scan tool displays O2S (v) 0.40.
OUTPUT: These data parameters are outputs or commands that come directly from
computer module(s). For example; the ignition spark advance is controlled
by PCM, on most vehicles, monitoring this PID shows spark output from
PCM. The scan tool would display IGN ADV(°) 10.
CALCULATED: These data parameters are calculated after analyzing various inputs to the
vehicle’s computer module(s). For example, the engine load. The PCM
calculates this from sensor inputs and displays it in a percentage.
PCM VALUE: Is information that is stored in the computer module(s) memory and deter-
mined to be useful to service technician. An example of this is TROUBLE
CODE value, the DTC that caused a freeze frame capture.
NOTE: Several different causes can have the same parameter indication. For information on
diagnostics consult vehicle service manuals.
DATA PARAMETER LIST
ABS FRP (0 - 655350kPA) or (0 - 95050.5PSI)
Absolute Fuel Rail Pressure is the fuel pressure at the engine when reading in refer-
ence to atmospheric pressure.
ABS LOAD (0 - 100%)
Absolute Load Value is the normal value of air mass per intake stroke displayed as a
percent.
ABSLT TPS (0 - 100%)
Absolute Throttle Position represents normal distance throttle is opened.
ACC POS D,E or F (0 - 100%)
Accelerator Pedal Position represents normal distance gas pedal is pressed.
BARO PRESS (0 - 255kPA) or (0 - 36.9PSI)
Barometric Pressure is normally received from a dedicated barometer, manifold abso-
lute pressure sensor and other inputs during certain modes of driving.
NOTE: The Baro Press may not be the same as some weather services Barometric
Pressure due to being read at sea level.
CALC LOAD (0 - 100%)
Calculated LOAD Value indicates load on engine.
CAT TEMPxy (-40°C - 6513.5°C) or (-40 - 9999.9F)
Catalyst Temperature Bank shall display catalyst substrate temperature for bank cata-
lyst, if used by control module strategy for on board diagnostics monitoring, bank,
sensor catalyst or temperature sensor.
