Circuit/System Description
The heated oxygen sensors (HO2S) are used for fuel control and catalyst monitoring. Each HO2S compares the oxygen content of the surrounding
air with the oxygen content of the exhaust stream. When the engine is started, the control module operates in an Open Loop mode, ignoring the
HO2S signal voltage while calculating the air-to-fuel ratio. While the engine runs, the HO2S heats up and begins to generate a voltage within a
range of 0-1,275 mV. Once sufficient HO2S voltage fluctuation is observed by the control module, Closed Loop is entered. The control module
uses the HO2S voltage to determine the air-to-fuel ratio. An HO2S voltage that increases toward 1,000 mV indicates a rich fuel mixture. An HO2S
voltage that decreases toward 0 mV indicates a lean fuel mixture.
The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed
Loop earlier and the control module to calculate the air-to-fuel ratio sooner.

Circuit Description
The manifold absolute pressure (MAP) sensor has a 5 V reference circuit, a low reference circuit, and a signal circuit. The engine control module
(ECM) supplies 5 V to the MAP sensor on the 5 V reference circuit, and provides a ground for the low reference circuit. The MAP sensor provides
a voltage signal to the ECM on the signal circuit relative to the intake manifold pressure changes.
Conditions for Running the DTC
* DTC P0697 is not set.
* The engine is running.
* This DTC runs continuously within the enabling conditions.
Conditions for Setting the DTC
P0107
The ECM detects that the MAP sensor voltage is less than 0.20 V for more than 5 s.
P0108
The ECM detects that the MAP sensor voltage is more than 4.80 V for more than 5 s.
Action Taken When the DTC Sets
DTCs P0107 and P0108 are Type B DTCs.
Conditions for Clearing the MIL/DTC
DTCs P0107 and P0108 are Type B DTCs.

Action Taken When the DTC Sets
The module uses a default value for the missing parameters.
Conditions for Clearing the DTC
* A current DTC clears when the malfunction is no longer present.
* A history DTC clears when the module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.
Diagnostic Aids
* Use the DTC Descriptor list above to determine the module which is not communicating.
* If there are multiple non-communicating modules choose the one closest to the data link connector (DLC).
* Use Data Link References (See: Powertrain Management/Computers and Control Systems/Information Bus/Testing and Inspection/Initial
Inspection and Diagnostic Overview) to determine if the module uses high or low speed GMLAN serial data communications
* Some modules may not have internal protection for specific voltage outputs and may open a battery positive voltage or ignition voltage
source fuse. If a voltage input fuse is open and no short is found in that circuit, ensure that no module output voltage circuit is shorted to
ground before replacing the module.
* This diagnostic can be used for any module that should communicate with high or low speed GMLAN serial data providing the vehicle is
equipped with the option that uses that module.

Circuit/System Testing
Note: If more than one module is not communicating use Data Communication Schematics (See: Powertrain Management/Computers and
Control Systems/Information Bus/Diagrams/Electrical Diagrams) to determine which module is closest to the DLC. Start diagnostics with that
module.
Terminal and connector identifiers will be different depending on the individual module being tested. Use Schematic Reference and Connector End
View Reference to determine which connector and terminal to access.
1. Using the DTC Descriptor and Diagnostic Aids, determine the module that is not communicating that should be tested.
2. Ignition OFF, disconnect the harness connector of the module that is not communicating.
3. Test for less than 2 ohms between the module ground circuits and ground.
瀚慖f greater than specified range, test the ground circuit for an open/high resistance.
Note: Only the high speed GMLAN modules have a wired serial data wake up circuit. Refer to the module schematics to identify which
modules have a wake up circuit. If the module that is not communicating does not have a serial data wake up circuit, proceed to step 5.
4. Ignition ON, verify that a test lamp illuminates between the high speed GMLAN serial data wake up circuit OR the accessory wake up serial
data circuit and ground.
