Ford F150 Pickup. Instruction — part 1251

z

Select PID/DATA MONITOR & RECORD.

z

Turn ignition switch to ON position or start engine and allow to idle.

z

Follow operating instructions from scan tool menu.

z

Select PIDs and press START to begin monitoring.

Compare actual PID values on scan tool to PID values in appropriate chart under PIN VOLTAGE/PID
VALUE CHARTS under PID DEFINITIONS & PIN VOLTAGE/PID VALUES. If PID value is not as
specified, perform appropriate SYSTEM TEST in SELF-DIAGNOSTICS - BI-FUEL - GASOLINE/LPG
article.

PID DEFINITIONS

NOTE:

To identify PCM connector, refer to illustration. See Fig. 4 .

NOTE:

This list contains AFCM-specific PID's only. Alternative fuel misdiagnosis can
occur if other operational symptoms are not considered. See PIN VOLTAGE
CHARTS - CUTAWAY, ECONOLINE, F450 SUPER DUTY, F550 SUPER DUTY,
PICKUP & RV CUTAWAY - GASOLINE & CNG article for gasoline related
information.

NOTE:

All references to 2V or 4V following an engine size or model is 2 or 4 valves per
cylinder.

PIN VOLTAGE/PID VALUE CHARTS

Notes To Typical Diagnostic Reference Value Charts

An attempt is made to provide as much information as possible; the diagnostic tool may not display all input
and output signals for each vehicle. Reference values may vary +/- 20% depending on operating conditions and
other factors. RPM values are axle and tire dependent. For downstream O2S (12, 22) greater activity will result
when catalyst monitor is active. See PID DEFINITIONS & PIN VOLTAGE/PID VALUES for PID
descriptions. For tests involving switches, the values will be switch OFF or ON.

NOTE:

This list contains AFCM-specific PID's only. Alternative fuel misdiagnosis can
occur if other operational symptoms are not considered. See PIN VOLTAGE
CHARTS - CUTAWAY, ECONOLINE, F450 SUPER DUTY, F550 SUPER DUTY,
