WARNING: This page is about a different variant/trim than selected.

ENGINE OIL LEVEL SENSOR AND CHECK THE POWERTRAIN CONTROL MODULE CONNECTION
1. Check for loose, damaged or corroded connections on the engine oil level and on the slave Powertrain Control Module.
  Are there any loose or damaged connections?
  
  Yes
  - Repair the wiring connections as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go to 2.
WIRING CHECK ON THE ENGINE OIL LEVEL AND THE POWERTRAIN CONTROL MODULE
1. Check the wiring for an open circuit or high resistance between the engine oil level and temperature sensor and PIN 35 of the connector on engine side of the slave powertrain control module.
  Is there a high resistance or open condition in the wiring?
  
  Yes
  - Repair the open circuit or high resistance in the wiring.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go to 3.
WIRING CHECK ON THE ENGINE OIL LEVEL SENSOR AND THE POWERTRAIN CONTROL MODULE
1. Check the wiring for a short circuit between the engine oil level sensor and PIN 35 of the connector on engine side of the slave powertrain control module.
  Is there a short circuit in the wiring?
  
  Yes
  - Repair the short circuit in the wiring.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go to 4.
CHECK ENGINE OIL LEVEL SENSOR OPERATION
1. Check that the engine oil level sensor is working properly.
  Is the engine oil level sensor is working properly?
  
  Yes
  - End of diagnosis.
  No
  - Replace the engine oil level and temperature sensor.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK RELATED PCM AND COMPONENT CONNECTIONS
1. Perform any Service Bulletins that apply.
2. Disconnect all PCM harness connectors.
3. Disconnect all related in-line harness connections (if equipped).
4. Disconnect the related component harness connectors.
5. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
6. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
9. With the scan tool, erase DTCs.
10. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
11. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Replace the Powertrain Control Module (PCM) in accordance with the Service information. Refer to MODULE, POWERTRAIN CONTROL (PCM), REMOVAL AND INSTALLATION .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  - Test complete.
