  NOTE:
  Check Connectors - Clean/Repair As Necessary.
3. Measure The Resistance Of The (K935) EGR Outlet Temperature Sensor Signal Circuit Between The EGR Outlet Temperature Sensor Harness Connector And The PCM C1 Harness Connector.
  Is The Resistance Below 3.0 Ohms?
  
  Yes
  - Go To 4
  No
  - Repair The (K935) EGR Outlet Temperature Sensor Signal Circuit For An Open Or High Resistance.
  - Perform The POWERTRAIN VERIFICATION TEST. Refer To POWERTRAIN VERIFICATION TEST .
Check The (K914) EGR Outlet Temperature Sensor Return Circuit For An Open/High Resistance
1. Measure The Resistance Of The (K914) EGR Outlet Temperature Sensor Return Circuit Between The EGR Outlet Temperature Sensor Harness Connector And The PCM C1 Harness Connector.
  Is The Resistance Below 3.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Repair The (K914) EGR Outlet Temperature Sensor Return Circuit For An Open Or High Resistance.
  - Perform The POWERTRAIN VERIFICATION TEST. Refer To POWERTRAIN VERIFICATION TEST .
Check The Resistance Value Of The Exhaust Gas Recirculation Outlet Temperature Sensor
1. Measure The Resistance Between The (K935) EGR Outlet Temperature Sensor Signal Circuit And The (K914) EGR Outlet Temperature Sensor Return Circuit At The EGR Outlet Temperature Sensor.
  Is The Resistance Between 200 Ohms And 2.4M Ohms?
  
  Yes
  - Go To 6
  No
  - Replace The EGR Outlet Temperature Sensor In Accordance With The Service Information. Refer To SENSOR, EGR TEMPERATURE, REMOVAL .
  - Perform The POWERTRAIN VERIFICATION TEST. Refer To POWERTRAIN VERIFICATION TEST .
Check Related Harness Connections
1. Disconnect All PCM Harness Connectors.
2. Disconnect All Related In-Line Harness Connections (If Equipped).
3. Disconnect The Related Component Harness Connectors.
4. 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.
5. Connect All PCM Harness Connectors. Be Certain That All Harness Connectors Are Fully Seated And The Connector Locks Are Fully Engaged.
6. Connect All In-Line Harness Connectors (If Equipped). Be Certain That All Connectors Are Fully Seated And The Connector Locks Are Fully Engaged.
7. Connect All Related Component Harness Connectors. Be Certain That All Connectors Are Fully Seated And The Connector Locks Are Fully Engaged.
8. With The Scan Tool, Erase DTCS.
9. Test Drive Or Operate The Vehicle In Accordance With The WHEN MONITORED And SET CONDITIONs.
10. With The Scan Tool, Read DTCS.
  Did The DTC Return?
  
  Yes
  - Replace And Program The Powertrain Control Module (PCM) In Accordance With The Service Information. Refer To MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform The POWERTRAIN VERIFICATION TEST. Refer To POWERTRAIN VERIFICATION TEST .
  No
  - The Wiring Or Poor Connection Problem Has Been Repaired.
  - Perform The POWERTRAIN VERIFICATION TEST. Refer To POWERTRAIN VERIFICATION TEST .
