Dorman Knock Sensor Connector 917-033 — Direct-Fit Replacement with Corrosion-Resistant Terminals

This replacement connector is manufactured to match the fit, function, and pin configuration of the factory part for specified applications. It is designed to address common failure points such as corrosion, brittle housing, or damaged terminals so the vehicle’s knock sensor can communicate properly with the engine control module. Dorman built this part using durable materials and quality control standards backed by decades of automotive component experience.

How does this connector match the original equipment?

The 917-033 connector is produced to the same shape, terminal layout, and mounting considerations as the factory connector so it installs without modification. Matching dimensions and electrical contact positions reduce the risk of poor connections or strain on wiring harnesses.

• OEM-style housing and latch geometry for secure fit
• Correct terminal spacing and contact type for reliable continuity
• Pre-engineered to align with factory mounting points

What problems does replacing the connector solve?

Replacing a worn or corroded knock sensor connector often restores proper sensor readings and prevents intermittent misfires, false knock detection, or engine management trouble codes. The new connector eliminates unreliable electrical contact caused by pitting, bent terminals, or cracked plastic.

• Replaces corroded or electrically compromised terminals
• Stops intermittent sensor signals that trigger fault codes
• Prevents further wiring damage from brittle or broken housings

What are the construction and durability features?

Dorman uses durable polymer and corrosion-resistant metal contacts to extend service life under engine-bay conditions. The materials and assembly processes are selected to withstand vibration, heat cycles, and exposure to common automotive fluids without losing electrical integrity.

• High-quality polymer housing resists heat and cracking
• Corrosion-resistant terminals maintain conductivity
• Robust latch keeps connector mated under vibration

How do I confirm this part fits my vehicle?

Fitment depends on make, model, year, and engine trim — Dorman recommends using the vehicle lookup tool or checking OEM part numbers. Verifying fit before purchase minimizes returns and ensures the connector hooks up cleanly to your existing knock sensor wiring.

• Input make, model and trim into the garage/fitment tool
• Compare terminal count and housing shape with the original
• Confirm mounting clip and latch orientation match factory unit

Who is this for: This connector is intended for DIY mechanics, professional technicians, and vehicle owners troubleshooting knock sensor faults or replacing damaged wiring harness connectors. If your vehicle has intermittent knock-sensor signals, visible terminal corrosion, or a cracked connector housing, the Dorman 917-033 offers a practical direct-replacement option to restore reliable sensor communication without expensive harness replacement.
