Dorman Ignition Knock Sensor Connector 917-033 Compatible Replacement Plug — Direct-Fit, Corrosion-Resistant

The Dorman 917-033 is a direct-replacement ignition knock (detonation) sensor connector engineered to restore the original connection between the knock sensor and vehicle wiring harness.

This connector is manufactured to match the fit and function of the factory part on specified applications, providing a clean, corrosion-free connection where an old or damaged plug has failed. Built from durable materials and supported by Dorman’s automotive expertise, the 917-033 aims to simplify repair, avoid splicing, and return sensor circuit integrity without replacing the entire harness.

What vehicle models will this Dorman connector fit?

The 917-033 is made for specific makes and model years—fitment depends on the vehicle’s original connector design. Dorman supplies this part as a like-for-like replacement for applications that used the same style knock sensor plug from the factory. Always check the vehicle compatibility tool or list to confirm exact match before ordering.

• Designed for select OEM applications that use the same connector style
• Intended as a one-to-one replacement for the factory plug
• Confirm fit by entering your vehicle make, model and trim in the garage tool

How does this connector restore sensor performance?

Replacing a corroded or broken plug with the 917-033 re-establishes the electrical path between the knock sensor and engine control module, which can resolve intermittent or failed sensor signals. The new connector provides solid contact and insulation to reduce the chance of future connectivity problems. This repair avoids cutting the harness or using temporary fixes that may degrade over time.

• Replaces worn or corroded factory connector to ensure clean electrical contact
• Prevents intermittent faults caused by loose or oxidized terminals
• Maintains original wiring routing and connector retention features

How durable and reliable is the Dorman 917-033 connector?

Dorman constructs this connector from quality materials chosen to withstand automotive underhood conditions, including heat, vibration and exposure to contaminants. The part is intended to provide consistent service life comparable to original components. Backed by Dorman’s product development and decades of aftermarket experience, it is a robust option for restoring function without replacing larger assemblies.

• Materials selected for resistance to corrosion and heat cycling
• Connector geometry preserves secure latch and terminal alignment
• Manufactured and supported by a brand with extensive automotive expertise

How do I confirm fit and install the replacement connector?

Before purchase, use the vehicle fitment or garage tool to verify that the 917-033 matches your vehicle’s original knock sensor plug. Installation typically involves unplugging the old connector, transferring terminals if required, or replacing the plug assembly as designed. If you’re unsure, consult a repair manual or a professional technician to ensure correct terminal seating and proper sealing.

• Verify compatibility using vehicle year, make, model and trim in the fitment tool
• Installation may require terminal transfer or simple plug swap depending on application
• Follow torque and routing guidance to prevent stress or chafing on the harness

Who is this for: The Dorman 917-033 connector is aimed at DIY mechanics and professional shops needing a reliable replacement for a damaged knock sensor plug. It’s a practical choice for anyone wanting to restore proper sensor connectivity without costly harness replacement—especially when the original connector shows corrosion, broken tabs or intermittent contact. Use the fitment tool to confirm compatibility and consult a technician if installation requires terminal crimping or wiring repairs.
