Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- DTCs P0606 and P0607 indicate the 5-volt reference circuit was shorted to ground. The engine may not start and the PCM may not communicate with the scan tool during a shot to ground in the 5-volt reference circuit.
- The EVAP system diagnostic can be monitored on the scan tool under the I/M System Information selection. When the EVAP test displays a YES status, indicating that the system diagnostic is completed, check for DTC P0450, P0452, or P0453 in the Last Test Failed screen of the scan tool. If there is no FTP sensor DTC displayed the EVAP system diagnostic has run and passed, indicating that no malfunction was present this time. DTCs MUST be cleared in order to view the Current Status of the system diagnostics being performed. Do not forget that the I/M System Information tests only indicate that the test has run, not if the test passed or failed. The Last Test Failed screen must be checked for related DTCs in order to determine the outcome of the diagnostic test involved.
