URO HA1317961 Ignition Knock Detonation Sensor

The URO Parts HA1317961 is a direct-fit replacement ignition knock sensor, also known as a detonation sensor, designed to restore proper engine timing and performance. This sensor monitors the engine block for abnormal combustion events—commonly referred to as engine knock, ping, or detonation—and relays that information to the engine control module (ECM) so timing and fuel delivery can be corrected in real time.

Manufactured by A.P.A. Industries under the URO Parts brand, this knock sensor is built to meet or exceed OEM specifications, offering a cost-effective alternative to expensive dealer components. The sensor is constructed using high-quality polymer and corrosion-resistant metal materials designed to withstand the thermal demands of the engine bay, with alloy conductors that minimize electrical resistance for accurate, reliable signal output.

Key Features:

• Direct-fit OE replacement design for straightforward installation
• Restores proper ignition timing for optimal power and fuel efficiency
• Constructed with corrosion-resistant metal and high-quality polymer housing
• Alloy conductors minimize electrical resistance for accurate readings
• Manufactured in ISO 9001 certified facilities
• Cost-effective alternative to OEM dealer pricing

A failed or malfunctioning knock sensor can result in poor fuel economy, reduced acceleration, and audible engine knock or pinging. Replacing a faulty unit with the URO Parts HA1317961 helps protect the engine from the long-term damage that uncontrolled detonation can cause.
