FAQs
What is a knock sensor used for?
A knock sensor detects the vibrations caused by pre-ignition or detonation (engine knock) within the combustion chamber. This information allows the ECU to retard ignition timing, preventing engine damage.
Does this sensor come with wiring?
Yes, the Haltech Knock Sensor - Bosch HT-011100 includes a matching plug and pins to facilitate wiring to your ECU.
What size bolt does this sensor use?
The sensor is designed for an 8mm (5/16") mounting bolt.
Can I use this sensor with any ECU?
It is designed to be used with Haltech ECUs. However, it can be used with other ECUs that support a Bosch-type knock sensor input and are properly configured.
How do I know if my engine is knocking?
Engine knock is often described as a metallic pinging or rattling sound. This sensor detects knock at levels far below what the human ear can typically hear.
What happens if my engine knocks without a sensor?
Prolonged engine knock can lead to severe internal damage, including piston crown damage, bent connecting rods, and head gasket failure.
Is this a genuine Bosch sensor?
Yes, this is a genuine Bosch knock sensor supplied by Haltech.
Troubleshooting
No knock signal detected by ECU
Verify the sensor is securely mounted with the correct 8mm bolt. Check all wiring connections between the sensor, plug, pins, and ECU for continuity and proper pinout. Ensure the ECU is configured to read the knock sensor input.
False knock alerts
Check for mechanical noises from the engine or exhaust that might be mistaken for knock. Ensure the sensor is not loose, as this can cause spurious readings. Verify ECU sensitivity settings are appropriate for the engine.
Sensor damaged or cracked
Inspect the sensor for any physical damage. If damaged, it will need to be replaced. Ensure the replacement is a genuine Haltech Bosch HT-011100 or equivalent compatible sensor.

Setup, Compatibility & Care
Setup: The Haltech Knock Sensor HT-011100 requires a secure mounting location on the engine block or cylinder head where vibrations indicative of knock are most likely to be transmitted. It uses an 8mm (5/16") mounting bolt. The sensor comes with a matching plug and pins, which need to be wired correctly to the appropriate inputs on your Haltech ECU or compatible engine management system. Consult your ECU's wiring diagram for specific input channels.
Compatibility: This sensor is designed to work with Haltech ECUs and other engine management systems that support a Bosch-type knock sensor input. Ensure your ECU has a dedicated knock sensor input channel and is configured to read its signal.
Care: Knock sensors are generally maintenance-free. Ensure the sensor is securely fastened and free from physical damage. Keep the electrical connector clean and free from corrosion. Avoid exposing the sensor to excessive heat or contaminants that could damage the wiring or housing.
