Generic OBD PID List

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

An X in the Freeze Frame column denotes both a mode 1 and mode 2 PID (real time and freeze frame).

	AIR	Secondary Air Status	On/Off
	CCNT	Continuous DTC Counter	Decimal
X	ECT	Engine Coolant Temperature	Degrees
X	FUEL SYS1	Fuel System Feedback Control Status-Bank 1	OL/CL/OL DRIVE^a /OL FAULT/CL FAULT
	IAT	Intake Air Temperature	Degrees
X	LOAD^b	Calculated Engine Load	%
X	LONG FT1	Current Bank 1 fuel trim adjustment from stoichiometry which is considered long term.	%
	MAF	Mass Air Flow Rate	gm/s-lb/min
	O2S11	Bank 1 Upstream Oxygen Sensor (11)	Volts
	O2S12	Bank 1 Downstream Oxygen Sensor (12)	Volts
	OBD SUP	On-Board Diagnostic System	OBD II OBD I OBD Combination of or None
	PTO	Power Take-Off Status	On/Off
X	RPM	Revolutions per Minute	RPM
X	SHRT FT1	Current bank fuel trim adjustment from stoichiometry which is considered short term.	%

X	VSS	Vehicle Speed Sensor	km/h-mph
CL = Closed loop using HO2S(s) as feedback for fuel control. OL DRIVE = Open loop due to driving conditions (heavy acceleration). OL FAULT = Open loop due to fault with all upstream HO2S sensors. CL FAULT = Closed loop fuel control, but fault with 1 upstream HO2S sensor.

^a OL = Open loop, has not satisfied conditions for closed loop.

^b Percent engine load adjusted for atmospheric pressure.

^c Individual oxygen sensor fuel trim adjustment is not supported.
