Replacement Part Number: 30530-PPL-A01 30530PPLA01, 30530-PNA-003, 30530PNA003, KS197, SU6143, 5S2320, 1580917 This Ignition Knock Detonation Sensor is especially designed for Acura RDX 2008-2012 RSX 2002-2006 TSX 2004-2007 Honda Accord 2003-2007 Civic 2002-2005 CR-V 2002-2009 Element 2003-2011. 1.Incorrect air and fuel mixture: If the air to fuel ratio is incorrect, this can lead to ignition problems Deposits in the cylinder: Dirt, grime and contaminants can get into the cylinder and create all kinds of problems. 2.Defective, unhealthy or incorrect spark plugs: the wrong type of spark plugs, plugs with deposit buildup or incorrect spark gap can lead to poor spark or incorrect spark timing 3.Improper timing: Sparks not firing at the correct time can lead to poor spark or incorrect spark timing, causing abnormal combustion in the engine cylinders 4.Your Toyota's oil pressure switch or oil pressure sensor communicates with your engine's computer and will turn on the oil light if the oil pressure is low. In some cases, they can fail due to oil leaks and must be replaced to prevent catastrophic damage to the engine Product optimization and solution points 1.The detonation sensor is used to measure the degree of engine shake, easy to install, stable performance, strong resistance. The ignition advance angle is adjusted when the engine shakes, thus ensuring the proper operation of the vehicle. 2.Knock sensors are used to protect the engine and help reduce engine power, and are built to accurately determine the vibration generated by a knock and effectively generate a voltage signal for your vehicle's computer. 3.The knock sensor is a device used to prevent knocking or sparking. Sensing sensitive, fuel-saving and environmental protection, smooth acceleration, improve power, eliminate cylinder noise and fault codes, effectively solve the problem of failure. Protect the engine mechanical parts, high quality parts, safe, stable and durable. Product installation location 1.The burst sensor is located on the engine block or screwed into the side of the block or under the intake microfolders, thus generating an input voltage that the ECM uses to measure dynamic engine vibrations Product composition and material quality 1.Made of high quality metal material with ABS plastic material, durable and corrosion resistant, in strict quality control, stable features and high reliability. 2.Made of good material, durable and corrosion resistant, effectively solve the problem of failure. Protect the engine mechanical parts, high quality parts, safe, stable and durable. 1.A knock sensor is a device used to prevent knocking or spark popping. It is used to detect engine knocking or sound, which is caused by abnormal combustion in the engine cylinder. Eliminates cylinder rattling and fault codes to effectively solve malfunction problems. Protects engine mechanical components 2.This burst sensor is designed to respond to high burst frequencies, adapts to shifts in engine burst frequency, making it a more flexible sensor that responds to the correct engine burst in a wide range of vehicle conditions accurately determines the vibration generated by the burst and efficiently generates a voltage signal for your vehicle's computer 3.The burst sensor is used to eliminate cylinder rattles and fault codes for effective troubleshooting Protects mechanical engine components sending signals to the Engine Control Module (ECM) to adjust timing and prevent detonation or spark bursts Quality confidence: 1.Consistent OEM specifications to ensure perfect fit of related parts - Durable and reliable use of material qualifications - Multidisciplinary testing such as balanced housing durability wheel load limiting seals, etc. to improve the quality of each unit 2.Made of high quality materials under strict quality control, stable characteristics and high reliability, the ignition detonation sensor allows the vehicle computer to monitor the combustion chamber, advance or delay ignition and valve timing or injector pulse width for optimal engine performance 1.12 months warranty.
