Circuit Description

The heated oxygen sensor (HO2S) heater reduces the time required for the oxygen sensor to reach operating temperature and maintains the

operating temperature during extended idle periods. When the ignition is turned to the ON position, ignition voltage is supplied directly to the

sensor heater. The engine control module (ECM) controls the heater operation by first modulating the control circuit to ground when the sensors are

cold. This prevents the possibility of thermal shock to the sensor, from condensation build-up on the sensor, by controlling the sensors rate of

heating. After a predetermined amount of time, the ECM commands the heaters ON continuously. Once the sensor reaches operating temperature,

the ECM may modulate the heater control circuit to ground, to maintain a desired temperature.

The ECM controls the heater by grounding the control circuit with a solid state device called a driver. The driver is equipped with a feedback

circuit that is pulled-up to voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring

the feedback voltage.

The HO2S utilizes the following circuits:

* A signal circuit

* A low reference circuit

* An ignition voltage circuit

* A heater control circuit

Conditions for Running the DTC

P0030, P0031, P0032, P0050, P0051, P0052

* The ignition voltage is between 10-18 volts.

* The engine speed is greater than 80 RPM, 240 RPM for LLT.

Component Testing

1. Remove the intake manifold and disconnect the appropriate fuel injector.

2. Verify the resistance of each fuel injector with one of the following methods:

* If the engine coolant temperature (ECT) sensor is between 10-32掳C (50-90掳F), the resistance of each fuel injector should be 1.25-1.75

ohm.

瀚慖f not within the specified range, replace the fuel injector.

* If the ECT sensor is not between 10-32掳C (50-90掳F), measure and record the resistance of each fuel injector with a DMM. Subtract the

lowest resistance value from the highest resistance value. The difference between the lowest value and the highest value should be equal

to or less than 0.45 ohm.

瀚慖f the difference is more than 0.45 ohm, add all of the fuel injector resistance values to obtain a total resistance value. Divide the total

resistance value by the number of fuel injectors to obtain an average resistance value. Subtract the lowest individual fuel injector

resistance value from the average resistance value. Compute the difference between the highest individual fuel injector resistance

value and the average resistance value. Replace the fuel injector that displays the greatest difference above or below the average.

Circuit/System Description

The engine control module (ECM) provides ignition voltage to the fuel pump flow control module whenever the engine is cranking or running. The

control module enables the fuel pump flow control module as long as the engine is cranking or running, and ignition system reference pulses are

received. While this enable voltage is being received, the fuel pump flow control module supplies a varying voltage to the in-tank fuel pump

module in order to maintain the desired fuel line pressure.

- Passenger Compartment Dimming 1 Circuit

Diagnostic Fault Information

Circuit/System Description

The instrument panel (I/P) lamp dimmer switch is used to increase and decrease the brightness of the interior backlighting components. The I/P

dimmer switch provides a voltage signal that will increase as the brightness of the lights are increased and decrease as the brightness of the lights

are decreased. The body control module (BCM) provides a low reference signal and a B+ voltage reference to the I/P dimmer switch. When the I/P

dimmer switch is placed in the desired position, the dimmed voltage setting is applied from the I/P dimmer switch through the I/P dimmer switch

signal circuit to the BCM. The BCM interprets the signal and applies the dimmed voltage to the I/P lamps supply voltage circuit and the interior

backlighting components dim to the requested level.

Conditions for Running the DTC

* Battery voltage must be between 9-16 V.

* Park lamps ON.

DTC P0990

- Transmission Fluid Pressure (TFP) Switch 5 Circuit High Voltage

Diagnostic Fault Information

Circuit/System Description

The transmission fluid pressure (TFP) switch 5 is part of the control solenoid valve assembly, which has no serviceable parts. The TCM supplies a

signal circuit to the TFP switch 5. The TFP switch 5 has an internal case ground. TFP switch 5 is normally closed or LOW. When oil pressure is

present at the TFP switch 5, the switch is open or HIGH. The normally high pressure control (PC) solenoid 3 controls pressure to the R1/4-5-6

clutch regular valve. The TCM monitors the TFP switch 5 signal circuit to determine the position of the R1/4-5-6 clutch regulator valve. When the

low and reverse clutch and 4-5-6 clutch are commanded OFF, pressure is present on the TFP switch 5. When the low and reverse clutch or the

4-5-6 clutch is commanded ON, the R1/4-5-6 clutch regulator valve moves and pressure to the TFP switch 5 is exhausted through the R1/4-5-6

clutch regulator valve.

- Fewer Controllers On Than Programmed

Circuit Description

Modules connected to the GMLAN serial data circuits monitor for serial data communications during normal vehicle operation. Operating

information and commands are exchanged among the modules. The modules have programmed information about what messages are needed to be

exchanged on the serial data circuits, for each virtual network. The messages are also supervised and some periodic messages are used by the

receiver module as an availability indication of the transmitter module.

DTC U2103 will set when fewer modules are detected on the buss before the modules can learn the other module IDs. If the communication buss is

opened, or if the module power supply is lost when the vehicle is in the OFF power mode, and then placed in the RUN power mode, U2103 will set

in specific modules.

Conditions for Running the DTCs

* Voltage supplied to the modules is in the normal operating voltage range.

* The vehicle power mode requires serial data communication to occur.

* The DTC U2100 does not have a current status.
