Scan Tool Data - Powertrain Control Module (PCM) (NGC)

SCAN TOOL DATA - POWERTRAIN CONTROL MODULE (PCM) (NGC)

The following chart lists data values taken from the Scan Tool Powertrain Control Module (PCM) data list for the NGC controller. The values were taken at key on, engine off and at idle. The data is to be used for reference only.

The following data values were recorded under the following conditions unless otherwise specified:

- No DTCs set
- Engine at operating temperature
- Vehicle in Park or Neutral
- A/C Off
- Speed Control Off
- Accessories Off
- Altitude at 297.2 meters (975 ft) above sea level

Data values may not be applicable for some models. Some data values can vary as much as 20 percent due to the following:

- Vehicle age and wear
- Altitude
- Weather
- Engine, Transmission and other Vehicle Options
- Aftermarket Accessories

There are footnotes located next to some values in the data table to reference specific conditions or additional information. They are listed in detail after the data table.






















Footnotes
1. Value may vary due to altitude and weather.
2. O2 Sensor will toggle from Low to High every few seconds.
3. Pre-catalyst O2 Sensors will toggle from 0.0 volt to 1.0 volt when operating in closed loop.
4. Post-catalyst O2 Sensors should remain near a fixed value.
5. Value may vary due to ambient air temperature.
6. Value will change due to fuel level change. Voltage will increase as available fuel decreases.
7. Will vary due to fuel level and ambient air temperature.
8. Can be different due to vehicle option.
