NTK 23532 Oxygen Sensor - Upstream Left or Upstream Right

Direct Fit Oxygen Sensor

NTK oxygen sensor 23532 is a specific-fit, heated sensor built for emission control applications that require threaded installation and OE-level form and function. It is engineered for import and domestic coverage, including Jeep Grand Cherokee and Dodge Ram 1500 applications.

Key Features

• Heated oxygen sensor for faster operating response.
• Specific-fit design for direct application matching.
• Threaded mounting type with an 18 mm thread diameter.
• 18.25 in. wiring harness length for application-specific routing.
• 4-wire configuration for the correct sensor circuit layout.

Detailed Description

NTK 23532 is part of the Direct Fit Oxygen Sensor line, a product line focused on application-specific replacement and broad coverage. NTK is known for oxygen sensor manufacturing and uses ceramic technology control from raw material through finished sensor production. This oxygen sensor is extensively tested during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. It is a direct-fit replacement for select Jeep Grand Cherokee and Dodge Ram 1500 applications, making it a practical choice when replacing a worn upstream sensor on those vehicles. This part cross-references Bosch 15825 and DENSO Auto Parts 234-4653 for the same application.

What It Helps Address

• Check engine light concerns related to oxygen sensor performance.
• Incorrect air-fuel feedback from a failing heated sensor.
• Emissions test failures caused by degraded sensor response.
• Rough idle or drivability issues tied to inaccurate exhaust readings.
• Replacement needs for threaded, specific-fit sensor applications.

Installation Notes and Tips

Verify the connector style, wire count, thread diameter, and harness length before installation. Match the upstream left or upstream right application exactly as listed in the fitment data for Jeep Grand Cherokee and Dodge Ram 1500. Use the vehicle’s service information for proper removal and installation procedures.
