  4. Measure resistance between cavities E-38 and E-15. See Figure "EGR Pressure Sensor Wiring" .
    1. If the resistance measurement is less than or equal to 5 Ω, Refer to "74.2.2 Check for Open" .
    2. If the resistance measurement is greater than 5 Ω, circuit E-38 or E-12 is open. Repair the open and refer to "74.2.2.1 Verify Repair" .

Section 74.2.2
Check for Open

Perform the following steps to check for an open. ‪

  1. Remove jumper cable.
  2. Measure resistance between cavities E-38 and E-15. See Figure "EGR Pressure Sensor Wiring" .
    1. If the resistance measurement is less than 5 Ω, E-38 is shorted to E-15. Repair short and refer to "74.2.2.1 Verify Repair" .
    2. If the resistance measurement is greater than 5 Ω, replace the sensor and refer to "74.2.2.1 Verify Repair" .
Section 74.2.2.1
Verify Repair

Perform the following steps to verify repairs for the EGR temperature or pressure sensor: ‪

  1. Connect all connectors.
  2. Start and run the engine.
  3. Road test the engine.
    1. If code 82 was not logged, no further troubleshooting is required.
    2. If code 82 was logged, please review this section from the first step to find the error. Refer to "74.2.1 Check EGR Delta-Pressure Sensor" . If this is the second time through the procedure, call the Detroit Diesel Customer Support Center (313–592–5800) or try a test ECM/ECU.
