2 DTC P0161 HEGO Heater Performance Bank 2 Sensor 2 Circuit/System Description Heated Exhaust Gas Oxygen Sensors (HEGO) are used for fuel control and catalyst monitoring. Each HEGO compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HEGO must reach operating temperature to provide an accurate voltage signal. A heating element inside the HEGO minimizes the time required for the sensors to reach operating temperature. Voltage is provided by the heater by an ignition voltage circuit through a fuse. With the engine running, ground is provided to the heater by the HEGO low control circuit through a low side driver within the engine control module (ECM). The ECM uses pulse width modulation (PWM) to control the HEGO heater operation to maintain a specific operating temperature range. Conditions for running the DTC P0030, P0036, P0050, or P0056 The ignition voltage is between volts. The engine speed is greater than 400 RPM. The DTC s run continuously when the above conditions are met for 1 second. P0053, P0054, P0059, or P0060 DTC s P0112, P0113, P0117, P0118, or P2610 are not set The ignition voltage is less than 32 volts The engine run time is greater than 3 seconds. The ignition is off for greater than 8 hours. The engine coolant temperature (ECT) is between 30 to +45 C ( 22 to +113F) at engine start up. The DTC s run once per drive cycle when the above conditions are met. P0135, P0141, DTC s P0116, P0117, P0118, P0125, or P0128 are not set. The ignition voltage is between volts The HEGO is at operating temperature. The HEGO is commanded on The DTC s run once per drive cycle when the above conditions are met for 120 seconds. 6.0 LITER ENGINE HEGO 1 Page 2 of 8

3 Conditions for setting the DTC P0030, P0036, P0050, or P0056 The ECM detects that the commanded state of the driver and actual state of the control circuit do not match for greater than 7 seconds. P0053, P0054, P0059, or P0060 The ECM detects that the HEGO heater is not within a specified resistance range at engine start up for greater than 1 second. P0135, or P0155 The ECM detects that the HEGO 1 heater current is greater than 3.1 amps, or less than 0.3 amp for greater than 10 seconds P0141, or P0161 The ECM detects that the HEGO heater current is greater than 2.9 amps, or less than 0.3 amp for greater than 10 seconds. 6.0 LITER ENGINE HEGO 1 Page 3 of 8

7 Circuit/System Verification 1. Engine idling, command the appropriate heated oxygen sensor heater to 100% and 0% with a scan tool while observing the control circuit status parameters listed below. Each parameter should toggle between OK and Not Run or Not Run and OK. HEGO Bank 1 or 2 sensor 1 or 2 check short to voltage status HEGO Bank 1 or 2 sensor 1 or 2 check open circuit status HEGO Bank 1 or 2 sensor 1 or 2 check short to ground status 2. Engine idling at operating temperature, observe the scan tool HEGO bank 1 or 2 sensor 1 or 2 heater parameter. The amperage should be within the specified range listed below: amps for HEGO bank 1 or 2 sensor amps for HEGO bank 1 or 2 sensor 2 3. Engine idling at operating temperature, move the related wiring and connections while observing the heated oxygen sensor heater parameter with a scan tool. The parameter should not change with movement. If movement affects the parameter, repair the appropriate harness or connector. 4. Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the freeze frame/failure record data. Circuit/System Testing 1. Ignition off, disconnect the harness connector at the appropriate HEGO. 2. Ignition on, verify that a test lamp illuminates between the ignition voltage terminal D and ground. If the test lamp does not illuminate, test the ignition voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, and the HEGO heater circuit fuse is open, test all components connected to the fuse, and replace as necessary. 3. Probe the appropriate control circuit terminal listed below with a test lamp connected to B+. Verify that the test lamp does not illuminate. HEGO 1 terminal E HEGO 2 terminal E If the test lamp illuminates, test the control circuit for a short to ground. If the circuit tests normal, replace the ECM. 4. Engine idling, the test lamp should illuminate or flash. If the test lamp does not illuminate, or flash, test the control circuit for a short to voltage, or an open/high resistance. If the circuit/connections test normal, replace the ECM. 6.0 LITER ENGINE HEGO 1 Page 7 of 8

8 Note: Less than 10 ohms on the ignition voltage circuit, or control circuit may set a DTC. If there is resistance on a circuit the driver will remain on and the scan tool will display greater than 0.0 amp. Performing this test may set additional DTC s. 5. Ignition off, connect a 10 amp fused jumper wire between the control circuit terminal listed below and the ignition voltage circuit terminal D. HEGO 1 terminal E HEGO 2 terminal E 6. Engine idling, observe the appropriate HEGO parameter. The scan tool should display 0.0 amps. If greater than the specified value, test the control circuit, and the ignition voltage circuit for high resistance. 7. If all circuits test normal, test or replace the appropriate HEGO. 6.0 LITER ENGINE HEGO 1 Page 8 of 8
