TPI’s knock sensors are all thoroughly tested against heat, cold, vibration and salt spray, our production facilities are QSO/ISO certified. Each knock sensor meets or exceeds OEM standards. We offer well over 200+ SKUs and we are continuously expanding our product line for the satisfaction of our customers. Each sensor is carefully packaged with a silica bag to avoid moisture and oxidization.
Knock sensors do fail over time due to vibration, corrosion and dirt. A defective knock sensor can lead to problems such as lower fuel economy, slow acceleration and an illuminated check engine light.
