Question
What causes knock sensor "false triggers" in turbocharged engines?
Answer
Vibrations from turbocharger and exhaust system mimic knock.
Explain
Turbocharged engines generate vibrations that trigger false knock signals. CHEPQ tools compare sensor readings with engine load and boost pressure—shielding the sensor wiring or replacing the sensor with a vibration-resistant model resolves the issue.
