Dorman A/C Compressor Flow Sensor — Direct-Fit OE FIX, Fits Select Lexus/Scion/Toyota Models

The Dorman 926-818 is a direct-fit air conditioning compressor flow sensor that lets you replace only the failed sensor instead of the entire compressor assembly.

Many dealers replace the whole A/C compressor when the factory flow sensor fails, driving up repair cost and labor. Dorman’s OE FIX solution supplies a replacement flow sensor engineered to fit the original compressor on specific Lexus, Scion and Toyota models, restoring sensing function while avoiding an expensive full-compressor swap. Always confirm vehicle compatibility with the garage fitment tool before ordering.

Which vehicles work with this sensor?

This Dorman flow sensor fits a range of Lexus, Scion and Toyota cars and SUVs built across several model years. Compatibility varies by trim and model year, so verify the Confirmed Fit indicator in the product garage tool; an information icon may indicate special fit notes to review.

• Lexus: ES300h, ES350, GS200t, GS350, GS450h, RX350, RX450h (select years).
• Scion: tC (2011–2016).
• Toyota: Avalon, Camry, Highlander, RAV4, Sienna (select years).
• Use the page garage tool and hover the blue “i” icon for any extra fitment details.

How does replacing the sensor save money compared with dealer repairs?

Dealers often replace the entire A/C compressor because the factory sensor is integrated, which increases parts and labor costs. This Dorman OE FIX sensor restores function without removing and replacing the full compressor, lowering parts expenses and shop time.

• Replaces only the failed sensor, not the whole compressor assembly.
• Reduces labor since retrofitting a sensor is quicker than full compressor replacement.
• Engineered to meet fit and performance expectations for a dependable repair.

Is the Dorman sensor reliable and easy to install?

The sensor is built from quality materials and has gone through fit and performance checks to help ensure a durable repair. Installation complexity depends on vehicle access and technician experience; some owners with mechanical skill can install it, while others may prefer a professional mechanic.

• Durable construction and U.S.-based engineering oversight for consistent quality.
• Tested for fit and function to match factory requirements where applicable.
• Installation may require minor compressor disassembly and refrigerant handling—professional installation recommended if unsure.

What should I check before ordering to ensure correct fit?

Fitment varies by trim and model year, so confirm your exact vehicle configuration using the garage fitment tool on the product page. If the Confirmed Fit bar shows an information icon, hover to read additional fit notes and match them to your vehicle’s specs.

• Enter vehicle year, make, and trim in the garage tool to confirm compatibility.
• Review any special fit notes shown by the blue “i” icon before purchase.
• Contact a technician or Dorman support if you have questions about fit or installation steps.
