RICHWEI Ignition Knock Detonation Sensor for Honda (30530PPLA01) — Direct-Fit, OE Replacement

RICHWEI's Ignition Knock (Detonation) Sensor 30530PPLA01 detects engine knock and sends signals so your engine control can adjust timing to protect the motor.

This direct-fit detonation sensor replaces OE numbers like 30530PPLA01, 30530-PL-A01, 30530PNA003 and others for many Honda and Acura models. Manufactured from durable, automotive-grade components and quality-checked during production, this sensor gives you the same mounting form and connector layout as the original equipment so installation is straightforward for experienced DIYers or professional mechanics.

How will I know when this knock sensor needs replacing?

Typical signs include persistent engine knock codes, unexpected ignition timing changes, or a check engine light related to cylinder knock or misfire diagnostics. Intermittent engine rattling under load or reduced throttle response can also point to a failing sensor.

• Check engine light with P0325–P0334 style knock codes
• Unusual pinging or metallic knocking under acceleration
• Engine timing adjustments or reduced power under load
• Visual damage or corrosion at the sensor or connector

Will this RICHWEI sensor fit my vehicle?

This sensor is compatible with specific Honda and Acura model years that use the same mounting and electrical interface as the listed OE numbers. Always confirm your vehicle year, make, model and engine trim against the part numbers before ordering to avoid fitment issues.

• Honda Civic: 2002–2005
• Honda CR-V: 2002–2009
• Honda Accord: 2003–2007; Element: 2003–2011
• Acura RDX: 2007–2012; RSX: 2002–2006; TSX: 2004–2008

What should I expect during installation and setup?

Installation is a straight replacement when the original sensor uses the same bolt location and connector type. You’ll typically need basic hand tools and should clear diagnostic trouble codes after installation; some vehicles may require relearn procedures for optimal timing control.

• Disconnect battery before starting and relieve engine heat
• Remove the old sensor’s bolt and unplug connector carefully
• Install the new sensor finger-tight, then torque to factory spec
• Clear codes and test drive to confirm knock-related codes are resolved

RICHWEI uses high-grade materials and multiple production checks to meet automotive durability expectations. The unit is manufactured to match the original part’s fit, connector style, and response characteristics, so it integrates with the engine management system without modification.

• Matches common OEM part numbers for direct compatibility
• Constructed from automotive-rated materials for temperature and vibration resistance
• Quality-controlled during production with repeated tests
• Sold as a single sensor in the package for immediate replacement
