TSC 001079.03 – 5volt Power Supply to TLS Sensors, Voltage Too High

TSC 001079.03 (TSC 1079.03)

Code: 001079.03

Shortcode: 1079.03

Description:

This diagnostic trouble code, TSC 001079.03, is triggered when the voltage measured at the positive lead of the power supply to the 5-volt components (TLS position sensor B53 and TLS oil pressure sensor B167) exceeds 5.25 volts. This indicates a possible circuit short to a supply lead or an internal interruption at the TSC.

Reaction:

When this error occurs, the affected sensors may not operate correctly, potentially leading to incorrect readings and impaired functionality of the TLS system.

Recommendations:

Inspect Power Supply Circuit:

  • Check for Shorts:
    • Examine the wiring for any signs of short circuits to a supply lead.
    • Repair any identified shorts in the circuit.

Inspect Sensors:

  • Check Sensor Connections:
    • Ensure that the TLS position sensor B53 and TLS oil pressure sensor B167 are properly connected and not damaged.
    • Replace any faulty sensors.

Verify TSC Internal Circuitry:

  • Check for Internal Faults:
    • Inspect the internal circuitry of the TSC for any interruptions or faults.
    • Repair or replace the TSC if necessary.

Note:

Ensuring the stability of the 5-volt power supply to the TLS sensors is crucial for accurate sensor readings and proper system functionality. Regular inspections and maintenance of the power supply circuit and sensors are recommended.
