Section 34.2
Troubleshooting Flash Code 29, PID 351/FMI 4

Flash Code 29 p 351/4 indicates the signal voltage for the Turbo Compressor In Temperature Sensor went below calibration limits. ‪

Section 34.2.1
Check the Turbo Compressor In Temperature Sensor Connector

Perform the following steps to check the Turbo Compressor In Temperature Sensor connector.‪

  1. Unplug the connector at the Turbo Compressor In Temperature Sensor.
  2. Measure resistance between cavity 1 and cavity 2. See Figure "TCI Connector and Turbo Compressor In Temperature Sensor" .
    Click to see this graphic in a separate window

    Figure 1. TCI Connector and Turbo Compressor In Temperature Sensor

    1. If measured resistance is greater than 5 Ω, refer to "34.2.2 Check for Open" .
    2. If measured resistance is less than 5 Ω, V-27 is shorted to V-59 on the ECU 68–pin connector. See Figure "ECM/ECU VIH Connector " . Repair the short and refer to "34.2.2.1 Verify Repairs" .

Section 34.2.2
Check for Open

Perform the following steps to check for short:‪

  1. Unplug the vehicle harness.
  2. Measure resistance between cavity V-27 and V-11. See Figure "ECM/ECU VIH Connector " .
    Click to see this graphic in a separate window

    Figure 2. ECM/ECU VIH Connector

    1. If resistance is less than 1.0 K Ω, wire V-27 is shorted to V-11. Repair and test.
    2. If resistance is greater than 1.1 K Ω, go to step 3 .
  3. Check for corrosion at the 2–pin and 68–pin connector.
    1. If corroded, clean corrosion from the terminals or replace the terminals. Refer to "34.2.2.1 Verify Repairs" .
    2. If terminals are clean, without corrosion, replace the Turbo Compressor Temperature Out Sensor. Refer to "34.2.2.1 Verify Repairs" .
Section 34.2.2.1
Verify Repairs

Perform the following steps to verify repairs.‪

  1. Turn ignition OFF. Reconnect all connectors.
  2. Turn ignition ON. Clear codes.
  3. Start and run the engine for eight minutes. Stop engine.
  4. Read inactive codes.
    1. If no codes are displayed, troubleshooting is complete.
    2. If code p 351/4 is logged with any other codes, review this section from the first step to find the error.
    3. If code p p 351/4 is not logged, but other codes are logged, refer to "18.3 First Step for Diagnosing a Fault Within the DDEC System" .
