Diagnostic Test

WARNING: This page is about a different car, the 2014 RAM 3500 HD and 2014 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

Possible Causes
EGR TEMPERATURE SENSOR SIGNAL CIRCUIT SHORTED TO GROUND
EGR TEMPERATURE SENSOR SIGNAL CIRCUIT SHORTED TO THE SENSOR GROUND CIRCUIT
EGR TEMPERATURE SENSOR
POWERTRAIN CONTROL MODULE

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE .

ACTIVE DTC
NOTE:
Diagnose and repair any system voltage DTCs before continuing with this test.
1. Turn the ignition on.
2. With the scan tool, select View DTCs.
  Is the DTC Active at this time?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
EGR TEMPERATURE SENSOR
1. Turn the ignition off.
2. Disconnect the EGR Temperature Sensor harness connector.
3. Ignition on, engine not running.
4. With the scan tool, read the EGR Temperature Sensor voltage.
  NOTE:
  The sensor voltage should be approximately 5.0 volts (plus or minus 0.1 volts) with the connector disconnected.
  
  Does the scan tool display the voltage as described above?
  
  Yes
  - Verify that there is good pin to terminal contact in the EGR Temperature Sensor and Powertrain Control Module connectors. If OK, replace the EGR Temperature Sensor.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (K932) EGR TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.
3. Measure the resistance between ground and the (K932) EGR Temperature Sensor Signal circuit in the EGR Temperature Sensor harness connector.
  Is the resistance above 10k Ohms?
  
  Yes
  - Go To 4
  No
  - Repair the (K932) EGR Temperature Sensor Signal circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK FOR THE (K932) EGR TEMPERATURE SENSOR SIGNAL CIRCUIT SHORTED TO THE (K915) SENSOR GROUND CIRCUIT
1. Measure the resistance between the (K932) EGR Temperature Sensor Signal circuit and the (K915) Sensor Ground circuit at the EGR Temperature Sensor harness connector.
  Is the resistance above 10k Ohms?
  
  Yes
  - Repair the short between the (K932) EGR Temperature Sensor Signal circuit and the (K915) Sensor Ground circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 5
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the EGR Temperature Sensor and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the EGR Temperature Sensor and Powertrain Control Module connectors.
4. Perform any Technical Service Bulletins that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Replace and program the Powertrain Control Module in accordance with the service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
