MODEL/YEAR VIN CODE APPLICATIONS 

MODEL/YEAR VIN CODE APPLICATION 

ENGINE CODE LOCATION 

Engine code information label is located on engine. See Fig. 2 . On most engines, engine code information label 
is located on valve cover or engine itself. On some engines, exact location of engine code information label is 
not available. Emission calibration number label located on driver's door or door post pillar, as well as engine, 
also identifies engine code number and revision number. Engine code and calibration number may be needed 
when ordering parts.

Pin Voltage/PID Value Charts - Econoline & Pickup - Gasoline & CNG 

INTRODUCTION 

Parameter Identification (PID) mode allows access to certain data values, analog and digital inputs and outputs, 
calculated values, and system status information. There are 2 types of PID lists available. The first is a Ford 
specific PID list that can be accessed by using New Generation Star (NGS) scan tool or Worldwide Diagnostic 
System (WDS). The second is a Generic OBD-II PID list. This is a standard set of PIDs that all manufacturer's 
scan tools can access. Generic PIDs are located at the end of each PIN VOLTAGE/PID VALUES chart. 

PIN VOLTAGE/PID VALUES charts are used for diagnosing intermittent symptoms and faults that are unable 
to be resolved during self-diagnostics. Pin tests ensure the Powertrain Control Module (PCM) is receiving and 
transmitting proper voltage and other signals. If diagnosing a symptom, see appropriate symptom in 
SYMPTOM TESTING under TEST PROCEDURES. 

PID values are continuously updated when accessing PIDs from a specific PID list. Before performing tests, 
ensure mechanical conditions have been inspected and self-diagnostics has been attempted. Technical Service 
Bulletins (TSBs) may also be helpful in correcting a hard to diagnose problem. 

TEST EQUIPMENT 

In order to read Parameter Identification (PID) values, a New Generation Star (007-00500 ) scan tool, 
Worldwide Diagnostic System (WDS) or other OBD-II compliant scan tool is required. A DVOM, 104-pin 
Breakout Box (014-00950 ) and appropriate adapter cable are used to check PCM pin values. If a breakout box 
is not available, PCM pin values can be checked by backprobing PCM connector. 

TEST PROCEDURES 

PIN VOLTAGE TESTING 

Access PCM connector. See POWERTRAIN CONTROL MODULE LOCATIONS . If a breakout box is 
available, disconnect negative battery terminal. Connect breakout box to PCM harness connector and PCM. 
Reconnect negative battery cable. Take desired measurements between ground pin and specified pin on 
breakout box. If breakout box is not available, take desired measurements between ground pin and specified pin 
at PCM connector (backprobe PCM connector). See appropriate illustration in PIN VOLTAGE/PID VALUE 

NOTE:

Article includes Cutaway, RV Cutaway and F450-550 Super Duty information.

CAUTION: When battery is disconnected, vehicle computer and memory systems 

may lose memory data. Driveability problems may exist until computer 
systems have completed a relearn cycle. See COMPUTER RELEARN 
PROCEDURES article in GENERAL INFORMATION before disconnecting 
battery.
