Testing Notes

1. Diagnostic reference values are based on engine at operating temperature; between 180°-220°F (82°-104°C) / ECT value = 0.8-0.5 Volts.

2. KOEO and hot idle test measurements are taken with vehicle in Park (ATX), Neutral (MTX).

3. Reference values shown in charts may differ substantially between vehicles due to various factors: component tolerance, driving conditions, weather, etc... The values on these charts were obtained at approximately 600 feet altitude above sea level at ambient temperatures from 10°-21°C (50°-70°F).

4. WAC and FP do not correspond to values given in the Pinpoint Tests due to differences in the way these signals are measured. The Monitor measures these signals with reference to PWR GND (60/40).

5. O2S in switching mode ranges from 0.2-0.9 DCV.

NOTE: The Powertrain Control Module (PCM) is not fully compatible with the EEC-IV Monitor. Because of this, some inputs and outputs register inaccurate readings and cannot be used. These pins read Not Applicable (NA) in the reference value columns. These pins can be monitored using a Rotunda Breakout Box 007-00033.
