Perform a pull test on each wire that relates to the turbochargers speed signal. Pull on each wire in order to verify that each wire is properly connected to each terminal and that each terminal is inserted into the connector.
Use 7X-1710 Multimeter Probes to measure the resistance between the points that are listed in Table 2. Wiggle the wiring between the P2 connector and the turbochargers speed sensor as you take each measurement.
Resistance Measurements For a 103-8 Code
Point    Point    Acceptable Resistance Value
P2-24     Terminal "1" on the engine harness connector for the turbochargers speed sensor     Less than five Ohms
P2-34     Terminal "2" on the engine harness connector for the turbochargers speed sensor     Less than five Ohms
P2-24     Engine ground     Open Circuit
P2-34     Engine ground     Open circuit    Expected Result:At least one of the resistance measurements is incorrect.Results:
High resistance between the electrical connectors - Identify the cause of the problem. Make the necessary repairs.STOP
Incorrect resistance to engine ground. - Repair: Identify the cause of the problem. Make the necessary repairs.STOP
All of the resistance measurements are correct. - Repair: Replace the turbocharger.STOPTest Step 6. Check the Electrical Power for the ActuatorRefer to Illustration 3. The truck wiring harness provides the +Battery to the engine wiring harness. The connectors that connect the truck wiring harness to the engine wiring harness are above the engine ECM.Note: Carefully following this procedure is a good way to identify the root cause of an intermittent wiring problem.
Carefully check the truck OEM wiring installation for the following problems:
Tripped circuit breaker or blown fuse
Damaged wiringDetermine the root cause of the problem if the circuit breaker is tripped or the fuse is blown. Continue with this procedure if the circuit breaker is not tripped and the fuse is OK.
Use 7X-1710 Multimeter Probes to determine the voltage at the engine harness connector for the truck wiring harness. Wiggle the truck wiring harness and the connectors on the truck wiring harness while you take the voltage measurement.Expected Result:Battery voltage is not at the engine harness connector.Results:
Battery voltage is not at the engine harness connector. - Repair: Determine the cause of the missing voltage. Make the necessary repairs to the truck wiring harness.STOP
Battery voltage is at the engine harness connector. - Repair: Use 7X-1710 Multimeter Probes to check for battery voltage at the engine harness connector for the actuator. Wiggle the engine harness and connectors while you take the voltage measurement.If the voltage is not equal to the battery voltage, repair the engine harness. Replace parts, if necessary. If the voltage at the engine harness connector for the actuator is OK, proceed to Test Step 7.Test Step 7. Check the CAN Data Link Between the Actuator and the Engine ECMNote: Carefully following this procedure is a good way to identify an intermittent problem.
Perform a visual inspection of the wiring between the P2 connector and the actuator. Look for these problems:
Damage that is caused
