About the Course:

This Diagnosing Bad Throttle Position Sensor microcredential trains technicians to identify, diagnose, and troubleshoot faults related to the Throttle Position Sensor (TPS) within hybrid electric vehicle powertrain systems. 

Learners will practice real-world diagnostic procedures including scanning for throttle position sensor-related fault codes, analyzing throttle angle and accelerator input data, inspecting sensor wiring and connectors, and testing sensor signal outputs using professional diagnostic tools. The course emphasizes safe diagnostic practices, proper use of scan tools and multimeters, and systematic troubleshooting techniques to accurately detect throttle position sensor failures that affect throttle response, engine performance, and electronic throttle control in hybrid electric vehicles.

To deepen your expertise in hybrid vehicle diagnostics and systems, explore our HEV Training Program.

Learning Objectives:

  • Identify common symptoms of a failing throttle position sensor such as poor acceleration, hesitation during throttle input, erratic engine idle, or illuminated warning lights 

  • Safely prepare the hybrid vehicle for diagnostic procedures by following proper electrical safety and vehicle shutdown protocols 

  • Use diagnostic scan tools to identify throttle position sensor fault codes and abnormal throttle angle readings 

  • Test throttle position sensor signals using a multimeter or oscilloscope 

  • Inspect throttle body wiring harnesses, connectors, and sensor mounting locations for damage, corrosion, or contamination 

  • Identify malfunctioning throttle position sensors affecting throttle control and engine response 

  • Interpret diagnostic data to determine the root cause of throttle input and engine performance issues 

  • Verify proper throttle response and sensor performance after repairs or sensor replacement

 

Course delivered via LMS and requires an Oculus VR headset for hands-on VR simulations.

At ImmerseLearn, we equip hybrid and electric vehicle technicians with the diagnostic skills required to service modern engine management and electronic throttle control systems through our HEV Technician Program. This microcredential strengthens sensor diagnostics, throttle system analysis, and electrical troubleshooting skills through immersive VR-based learning. 

Throttle Position Sensor Diagnostics −
Learn how to identify faulty throttle position sensors by analyzing engine control module (ECM) data, reviewing diagnostic trouble codes, and evaluating throttle angle and voltage signal outputs. Technicians develop the ability to quickly isolate sensor-related faults that affect throttle response, engine acceleration, and electronic throttle control performance.
Diagnostic Safety Practices +
Follow proper safety protocols when diagnosing hybrid vehicle throttle and engine systems. This includes performing correct vehicle shutdown procedures, isolating electrical power where necessary, and safely using diagnostic equipment while working near the throttle body, electronic control modules, and other engine components.
Fault Cause Analysis +
Recognize and evaluate common factors that can lead to throttle position sensor failures, such as wiring damage, corroded connectors, throttle body buildup, sensor misalignment, or internal sensor defects. Technicians will learn to interpret diagnostic data and vehicle symptoms to accurately determine the source of the problem.
Sensor Service and Performance Verification +
Perform appropriate corrective actions including repairing damaged wiring, cleaning or securing connectors, servicing the throttle body, adjusting the sensor if required, or replacing a faulty throttle position sensor. Technicians will then verify the repair by confirming correct throttle angle readings, stable sensor signals, and proper vehicle response during operation.

By completing this microcredential, technicians will gain the confidence and technical expertise needed to diagnose throttle position sensor failures, restore accurate throttle control, and improve engine responsiveness and performance in hybrid electric vehicles.
