DTC Type Reference
Powertrain Diagnostic Trouble Code (DTC) Type Definitions (See: Diagnostic Trouble Code Descriptions/Powertrain Diagnostic Trouble Code
(DTC) Type Definitions)
Scan Tool Reference
Control Module References (See: Testing and Inspection/Programming and Relearning)for scan tool information
Circuit/System Verification
1. Observe the scan tool 5 V reference 1 circuit status and the 5 V reference 2 circuit status parameters. Verify the parameters display OK.
2. Ignition ON, observe the DTC information with a scan tool. DTC P0641 or P0651 should not set on this ignition cycle.
3. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed
from the Freeze Frame/Failure Records data.
Circuit/System Testing
Note: Additional DTCs may set when disconnecting components.
1. Ignition OFF, disconnect the harness connector of all the sensors connected to the 5 V reference bus for the applicable DTC. Refer to
Circuit/System Description.
Note: A short to voltage on the signal circuit of certain components may cause this DTC to set.
2. Ignition ON, test for 4.8-5.2 V between one of the 5 V reference circuits and ground.
瀚慖f less than the specified range, test all of the 5 V reference circuits for a short to ground. If all circuits test normal, replace the K20 ECM.
瀚慖f greater than the specified range, test for a short to voltage on all of the 5 V reference circuits, or the signal circuit for each component
associated with the appropriate 5 V reference bus for a short to voltage. If all circuits test normal, replace the K20 ECM.
3. Connect each component associated with the appropriate 5 V reference bus, one at a time, while monitoring the voltage. The voltage should
not change more than 1 V.
瀚慖f the voltage display changes more than the specified range when a component is connected, replace the component.
