Allmotorparts Knock Sensor for Honda & Acura — Direct-Fit 30530-PPL-A01 Replacement, OE Connector, Restores Timing

Allmotorparts knock sensor replacement that fits many Honda and Acura models and detects engine knock so the ECU can adjust timing.

This aftermarket knock sensor from Allmotorparts is designed as a direct-fit substitute for part numbers 30530-PPL-A01 and 158-0917. It mounts to the intake manifold, cylinder head, or engine block and converts abnormal vibration from detonation into an electrical signal your engine control unit can use. Replace a failing sensor to stop fault codes, restore proper timing control and recover drivability—confirm vehicle fitment in the compatibility list before ordering.

How will I know the knock sensor is failing?

Failing knock sensors often trigger an illuminated check engine light and may coincide with rougher acceleration or reduced fuel efficiency. You might also notice unusual engine noises under load or decreased overall performance as the ECU limits timing to protect the engine.

• Check Engine Light (DTCs related to knock sensor or misfire)
• Poor acceleration and reduced power under load
• Lower fuel economy after the fault appears
• Intermittent or constant engine pinging or tapping noises

Which vehicles is this Allmotorparts sensor compatible with?

This sensor is made to match OE fitment for many Honda and Acura cars and cross-replaces common OEM numbers. Always verify the year, make and model of your vehicle against the compatibility list to ensure correct fitment before purchase.

Yes — this Allmotorparts unit is intended as an aftermarket equivalent to OEM part numbers 30530-PPL-A01, 30530PPLA01, 158-0917 and 1580917. It follows the original sensor’s mounting, connector style and electrical characteristics for an easy swap.

• Replaces: 30530-PPL-A01, 30530PPLA01, 158-0917, 1580917
• OE-style connector and thread pattern for direct installation
• Bench-tested for vibration response with accelerometer testing

What should I watch for when installing the replacement sensor?

When servicing the knock sensor you may need to remove the intake manifold or access the block, and debris can fall into engine openings. Work in a clean area, cover open ports, and follow torque specs for the sensor to avoid damage and ensure a proper seal.

• Protect intake openings from grit when removing manifold components
• Use the manufacturer-recommended torque value for sensor threads
• Confirm electrical connector seating and inspect wiring for damage
• Clear related Engine Control Module codes after installation

This part is an aftermarket replacement manufactured by Allmotorparts, not a genuine Honda/Acura OEM component. It is produced to meet OE form, fit and function standards but is sold as a third-party alternative. Verify your vehicle model and year against the compatibility section to ensure proper selection.

Who this is for: DIY mechanics and independent repair shops seeking a cost-effective, direct-fit knock sensor for specified Honda and Acura models. It suits owners troubleshooting knock-related fault codes, those restoring lost performance or anyone replacing a damaged sensor with a tested aftermarket option.
