< Back Throttle Body A valve assembly that regulates airflow into the engine. The throttle body contains a butterfly valve controlled by the accelerator pedal, either mechanically or electronically (drive-by-wire). It governs air intake volume, directly affecting power output. Carbon buildup can cause poor idle, hesitation, or reduced fuel economy. Cleaning with throttle cleaner restores smooth airflow. Electronic throttle bodies require adaptation using diagnostic tools after cleaning. Maintaining a clean and calibrated throttle ensures responsive acceleration and stable engine operation.

< Back Spark Plug Tester A tool that checks spark plug condition and ignition strength. A spark plug tester helps determine if a spark plug is firing correctly under pressure. It visually displays spark consistency and color, indicating combustion quality. Weak or intermittent sparks suggest fouling or coil issues. Testing each plug ensures balanced ignition and optimal fuel efficiency. In modern workshops, spark testers can simulate compression pressure for realistic evaluation. Routine spark testing prevents engine misfire, rough running, and power loss. Previous Next Related Diagnostic Guide This topic is part of CHEPQ’s system-level diagnostic framework.

Question How does TPMS interact with the vehicle’s ECU? Answer Sensors transmit pressure/temperature data to the ECU, which analyzes it and triggers alerts if values are out of range. Explain The ECU polls sensors every 10-30 seconds (varies by speed) and integrates TPMS data with other systems (e.g., disabling cruise control if pressure is critically low). CHEPQ scanners read ECU TPMS logs to review historical data (e.g., “Pressure dropped to 18 PSI at 2:15 PM”).
