P1027 VOLVO – Internal Throttle Body Failure

VOLVO Code P1027: Causes, Symptoms, and Repairs


What does code P1027 mean on a VOLVO?

Code P1027 is specific to Volvo vehicles. Its generic description is “Throttle Body Internal Fault”, which indicates an anomaly detected by the Engine Control Module (ECM) in the throttle control system. However, depending on your Volvo’s model and year, the exact description may vary. This code is often related to a mechanical, electrical, or software malfunction of the throttle body or its associated components.


Possible causes of code P1027

  1. Electrical problems:
  • Damaged wiring harness, faulty connectors (broken, corroded, or poorly connected pins).
  • Short circuit or open circuit in the throttle body circuits.
  1. Throttle body failure:
  • Faulty throttle actuator motor.
  • Malfunctioning Throttle Position Sensor (TPS).
  1. Mechanical fouling:
  • Carbon buildup blocking throttle movement.
  1. Software error:
  • Incorrect calibration or need for ECM update.

Symptoms associated with code P1027

  • Illuminated engine light (“Check Engine” or “Service Engine Soon”).
  • Driving problems:
  • Unstable idle or engine stalling.
  • Hesitation during acceleration.
  • Limp mode activated (reduced power).
  • Stuck or irregular engine RPM.

Recommended repair procedures

  1. Visual inspection:
  • Inspect the throttle body electrical harness and connectors (look for bent, corroded pins, or exposed wires).
  • Clean the throttle body with a suitable product to remove carbon (if necessary).
  1. Electrical tests:
  • Use a multimeter to check the voltage and resistance of the TPS and actuator motor (refer to specific Volvo values).
  • Look for short circuits or lack of continuity in the circuits.
  1. Software diagnostics:
  • Use a Volvo diagnostic tool (such as VIDA) to:
    • Read live data from the TPS and throttle.
    • Check for software errors or necessary updates.
  1. Replacement or reset:
  • If the throttle body is faulty, replace it with an original or certified part.
  • Reset throttle adaptations via the diagnostic tool after repair.

Additional technical information

  • Affected models: This code is common on Volvos equipped with Drive-by-Wire electronic systems (without accelerator cable).
  • Precautions:
  • Disconnect the battery before any electrical work.
  • Avoid manually forcing the throttle, as this could damage the actuator motor.
  • Specific resources: Consult Volvo Technical Service Bulletins (TSB) for manufacturer solutions related to this code.

If the problem persists

  • Consult a professional: Volvo electronic systems often require specialized tools for accurate diagnosis.
  • Check the vehicle’s history: Recurring throttle body problems may indicate a design flaw or premature wear.

Note: Exact technical information varies by model and year. Contact a Volvo dealer for data specific to your vehicle.
