Dorman Knock Sensor Connector Replacement, Compatible with Select Models, Corrosion-Resistant

The Dorman 917-033 ignition knock (detonation) sensor connector is a direct-replacement electrical plug engineered to restore reliable signal connection and fit where the original connector has deteriorated.

This replacement connector is built to match the original equipment's shape and function so your vehicle's knock sensor maintains proper contact and communication with the engine control system. It is intended for specific applications — verify fit with your vehicle's make, model and trim — and is constructed from durable materials to resist corrosion and wear that commonly cause electrical faults.

How does this connector restore sensor function?

When the factory connector becomes corroded, cracked or loses secure pins, the knock sensor can lose signal or produce intermittent readings. This Dorman connector replaces the damaged plug so the sensor can send consistent electrical signals to the engine control unit.

• Replaces the original-style housing and terminal arrangement for compatible applications
• New contacts provide clean electrical continuity
• Durable plastic resists heat and engine-bay chemicals

Will this part fit my vehicle?

Fitment is vehicle-specific; the connector is manufactured to match select OEM configurations rather than a universal size. Always confirm compatibility using your exact year, make, model and trim in the garage-fit tool or parts lookup.

• Designed to match OEM pin layout and locking features
• Check the garage tool to confirm model-specific fit
• Intended as a direct replacement for listed applications only

What makes this connector durable for under-hood use?

The connector is made from robust, heat-resistant materials with corrosion-resistant contacts so it holds up to the temperature and chemical exposure typical in an engine compartment. Proper sealing and secure locking geometry reduce the risk of moisture intrusion and vibration-related loosening.

• High-quality plastics withstand heat and oils
• Corrosion-resistant metal contacts ensure long-term conductivity
• Locking tab secures the mating sensor connector to prevent disconnection

How easy is installation for a DIYer?

Installation is straightforward for someone comfortable with basic automotive electrical work: disconnect the battery, unplug the old connector, and attach the new connector to the existing wiring and sensor. If pins or wiring are damaged, additional crimping or splice work may be required.

• No special tools needed for plug-and-play replacements
• May require basic hand tools for clip release and battery disconnection
• Refer to vehicle repair guides if wiring repairs are necessary

Who is this for: The Dorman 917-033 connector is aimed at vehicle owners, independent mechanics and repair shops that need a reliable, OEM-style replacement for a failed or corroded ignition knock (detonation) sensor connector. It is ideal for those who want a cost-effective, durable part that restores proper sensor connection without replacing the entire sensor assembly. Confirm fitment with your vehicle's year, make and model before purchasing to ensure compatibility.
