Walker Products 242-1033 ignition knock (detonation) sensor for the 1999-2000 Honda Civic 4-cylinder 1.6L and other vehicles detects the vibration of knock and detonation in the engine. Spark knock can cause internal engine damage, reduced fuel economy and drivability issues, so the sensor lets the ECU retard spark when knock occurs.
- Monitors engine vibration frequencies to pick up knock or detonation events
- Lets the ECU adjust ignition timing in real time to prevent spark knock
- Tuned to the specific resonant frequency of knock in a given engine platform
- Heat- and oil-resistant materials suited to the conditions at the engine block and cylinder head
- Corrects spark advance during knock conditions to support fuel efficiency, performance and emissions
Quick facts
- Part: Walker Products 242-1033 ignition knock (detonation) sensor
- Fits: the 1999-2000 Honda Civic 4-cylinder 1.6L and other vehicles
- Condition: New
A failing knock sensor can bring a fault code such as P0325 or P0330, pinging under load or poorer fuel economy. These signs alone do not prove the sensor is at fault, and a damaged wire at its connector is another common cause.
Fits
The 1992-1993 Acura Integra 4-cylinder 1.7L, the 1994-2001 Integra 4-cylinder 1.8L and the 1994-1997 Honda Civic Del Sol 4-cylinder 1.6L are among the many vehicles this OE replacement sensor fits. It is engineered to match OE specifications for frequency range, sensitivity and electrical output. This listing is one sensor, the quantity these cars call for.

Is the Walker Products 242-1033 sensor right for a 1999-2000 Honda Civic 4-cylinder 1.6L?
Yes. Walker Products 242-1033 fits the 1999-2000 Honda Civic 4-cylinder 1.6L. For other years and engines, open the "Vehicles it fits" section and check your exact car.
Do I need to buy a wiring harness separately for this Walker Products sensor?
Yes, if your car needs one. This listing is one sensor with no wiring harness or mounting hardware.
How long is the sensor and what is its threaded end diameter?
This sensor is 50.02 mm long with a 12.7 mm threaded end diameter. It has a female circular connector and one male blade terminal.
Can a P0325 or P0330 code mean this sensor needs replacing?
It can. P0325 and P0330 are knock-detection codes, and if the sensor itself has failed, Walker Products 242-1033 replaces it.
Does Walker Products 242-1033 replace the 30530PV1A01 sensor?
Yes. 30530PV1A01 is on the interchange list for Walker Products 242-1033, along with 30530PV7A01 and KS66.
